Abstract
BACKGROUND This study evaluated endocrine responsiveness (ER) to physical stress (contact vs. non-contact nature of play) during team handball matches, according to the playing positions, thereby contextualizing the contact nature of the handball match. METHODS The participants were ten male team handball players (24.1±3.17 years, 188.2±6.42 cm, 94.6±9.6 kg) divided into two groups: contact playing positions (CPP) and non-contact playing positions (NCPP). To evaluate the ER, the salivary cortisol (C), testosterone (T), and alpha-amylase (AA) concentrations were assessed before the game, during the halftime break, and after the match. Moreover, playing time (PT) and the number of contacts (NC) were counted post-match by video analysis. To determine possible differences between PT and the NC in the first and second halves of the match, a paired-sample t-test was used. The differences among ER-measures were calculated by the magnitude-based Cohen's effect size. Possible associations between NC and ER were analyzed by comparing CPP and NCPP in C, T, and AA. RESULTS The CPP group performed significantly more physical contacts, while there was no difference in playing time between the groups. A stronger C response was evidenced in players with a longer playing time. During the game, the C response was directly determined by physical contact, with CPP players showing a stronger C response than NCPP players. CONCLUSIONS This study provided evidence of the importance of contact actions during matches and training sessions, as a parameter of calculating training loads and preparing strategies for recovery and injury prevention. Further studies examining larger samples are warranted.

Analysis of Progressive Muscle Relaxation on Psychophysiological Variables in Basketball Athletes. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:17065. [PMID: 36554945 PMCID: PMC9778808 DOI: 10.3390/ijerph192417065] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 12/02/2022] [Accepted: 12/05/2022] [Indexed: 06/17/2023]
Abstract
The purpose of this study was to evaluate the effects of a progressive muscle relaxation program on psychological (stress levels, anxiety, and mood states) and physiological (blood pressure and heart rate) variables in basketball athletes. Fifty-nine basketball players, aged 14 to 19 years, and members of Bauru Basket team, were recruited for this study and grouped into control group (CG, n = 30) and intervention group (IG, n = 29). The participants were evaluated, before and after the intervention, by the following means: Competitive State Anxiety Inventory-2 (CSAI-2), to measure the pre-competitive anxiety state, i.e., how anxious each athlete felt just before the competition; Brunel Mood Scale (BRUMS), an instrument for early detection of overtraining syndrome; Recovery-Stress Questionnaire for Athletes (RESTQ-Sport), to identify the extent to which each athlete was physically or mentally stressed and the athlete's current capability for recovery; Athlete Burnout Questionnaire (ABQ), specifically developed for athletes. The IG athletes participated in 12 progressive muscle relaxation sessions, a practice for tensing or tightening a specific muscle until an ideal state of relaxation is reached. Each participant had blood pressure and heart rate measured before and after every session. The CG athletes were evaluated similarly to those in the IG but without relaxation. The results showed statistically significant differences in cognitive anxiety (p = 0.039) and specific stress (p = 0.016) between CG and IG before the intervention; in addition, a significant heart rate decrease (p < 0.01) between IG and CG was noted.

Abstract
The present study aimed to investigate the impact of a basketball competition on the pre-competitive anxiety and Heart Rate Variability (HRV) of young female basketball players. A total of 12 female basketball players participated in this cross-sectional study. Girls had a mean age of 14 (1.41) years old and a mean experience of 4 (0.85) years practicing basketball. The pre-competitive anxiety and the HRV was assessed the week before and immediately before and after the match. Results showed a significant reduction (p-value < 0.05) of the several HRV variables after the match compared to baseline and pre-competition measures. However, differences between baseline and pre-competition were not found. Furthermore, a significant increase in somatic anxiety after the competition was reported. Taking into account HRV, somatic anxiety, and cognitive anxiety results, young female basketball players did not exhibit an increase in pre-competition anxiety. HRV measurements before competition can help coaches and physical trainers to identify female players with higher pre-competitive anxiety and propose intervention to manage it. Future studies should investigate the impact of coaches and parents on the pre-competitive anxiety of female and male basketball players.

Abstract
The purpose of this study was to investigate the effect of transcranial pulsed current stimulation (tPCS) on fatigue delay after medium-intensity training. Materials and Methods: Ninety healthy college athletes were randomly divided into an experimental group (n = 45) and control group (n = 45). The experimental group received medium-intensity training for a week. After each training, the experimental group received true stimulation of tPCS (continuous 15 min 1.5 mA current intensity stimulation). The control group received sham stimulation. The physiological and biochemical indicators of participants were tested before and after the experiment, and finally 30 participants in each group were included for data analysis. Results: In the experimental group, creatine kinase (CK), cortisol (C), time-domain heart rate variability indices root mean square of the successive differences (RMSSD), standard deviation of normal R-R intervals (SDNN), and frequency domain indicator low frequency (LF) all increased slowly after the intervention. Among these, CK, C, and SDNN values were significantly lower than those in the control group (p < 0.05). Testosterone (T), T/C, and heart rate variability frequency domain indicator high frequency (HF) in the experimental group decreased slowly after the intervention, and the HF value was significantly lower than that in the control group (p < 0.05). The changes in all of the indicators in the experimental group were smaller than those in the control group. Conclusion: The application of tPCS after medium-intensity training enhanced the adaptability to training and had a significant effect on the maintenance of physiological state. The application of tPCS can significantly promote the recovery of autonomic nervous system function, enhance the regulation of parasympathetic nerves, and delay the occurrence of fatigue.

Abstract
Purpose: A basketball match is characterized by intermittent high-intensity activities, thereby relying extensively on both aerobic and anaerobic metabolic pathways. Here, we aimed to compare the metabolic fluctuations between the four 10-min quarters of high-level basketball games using metabolomics analyses. Methods: 70 male basketball players with at least 3 years of experience in the Iran national top-league participated. Before and after each quarter, saliva samples were taken for subsequent untargeted metabolomics analyses, where Principal component analysis (PCA) and Partial least squares-discriminant analysis (PLS-DA) were employed for statistical analysis. Results: Quarters 1 and 3 showed similar metabolic profiles, with increased levels of ATP turnover (higher Lactate, Pyruvate, Succinic Acid, Citric Cid, Glucose and Hypoxanthine), indicating more reliance on anaerobic energy systems than quarters 2 and 4. In comparison, quarters 2 and 4 showed a reduction in Valine and Lucien and an increase in Alanine, Glycerol, AcetoAcetic Acid, Acetone, Succinic Acid, Citric Acid, Acetate and Taurine that was not present in quarters 1 and 3, indicating greater reliance of aerobic energy contribution, fat metabolism and gluconeogenesis. Conclusion: Our data demonstrate that the higher intensity of movements in the first quarter, where players are more rested, induce an increase in anaerobic energy contribution. This seems to be the case also for the third quarter that follows 15 min of rest, whereas the accumulated fatigue and reduction of high-intensity movements in the second and fourth quarters also reduces the speed of energy production and players thereby utilize more aerobic energy.

Abstract
The objective of this study is to show the links and differences in the expressions of competitive anxiety in the face of the existence of resilient resources in young athletes, according to sporting (years of experience) and personal (gender) characteristics. To meet these aims, the participants answered the Resilience Scale (RS-14) and the Competitive State Anxiety Inventory-2R (CSAI-2R). The sample consisted of 241 adolescent handball and basketball players between 14 and 17 years old. Different analyses were performed, including a differential and multivariate descriptive, a correlation, and a multiple regression. The results showed that anxiety was negatively related to resilience in its acceptance dimension. It was shown that girls showed higher levels of somatic anxiety, while boys showed higher levels of acceptance. Statistically significant differences were found in the resources for acceptance in favor of boys, while there were significantly different indicators in somatic anxiety and self-confidence in favor of girls. The sports experience was positively related to resilience and negatively to anxiety. Although the existence of indicators of cognitive anxiety (e.g., recurrent thoughts or rhyming), coaches and athletes need to understand that they are also indicators of a necessary activation for psychological functioning. Channeling such a process through psychological training of different skills will enhance the capacities for self-confidence.

Abstract
Objectives The present study proposes a model for the relationships among competitive martial arts players’ positive emotions, hope (path and emotive force ideas), sense of control, self-handicapping, and precompetition state anxiety (PCSA). The model seeks to advance our understanding around the causal and mediating effects between these variables and, thus, has important implications for theory and practice in the field of sports and exercise psychology. Method A total of 327 participants (male: 255, female: 72; age: 21.45 ± 2.78 years; athletic training: 6.27 ± 2.54 years) in the China University Wushu Sanda Championship 2019 were surveyed. Within 2 h before the match, PCSA, sports hope, sense of control, anxiety, and self-handicapping were measured. Results The findings of the present study showed that (1) positive emotions have a significant positive correlation with path and emotive force ideas, anxiety orientation, ability to cope, goal attainment, and sense of control; (2) path and emotive force ideas were significantly positively correlated with anxiety orientation, ability to cope, goal attainment, and sense of control and significantly negatively correlated with anxiety intensity and self-handicapping; and (3) the path idea acted as a partial negative mediator between positive emotion and anxiety intensity, and the sense of control played a partial negative mediator between the emotive force idea and self-handicapping. Conclusion (1) Players’ positive emotions can predict the sense of hope. It also tends to interpret the anxiety intensity as a positive challenge rather than a negative sense of control. (2) Players with a higher path idea also tend to have lower negative emotion, anxiety intensity, and self-handicapping; (3) martial arts players’ path idea has a significantly higher predictive power for the sense of control than the emotive force idea. Still, both path and emotive force ideas can indirectly affect the intensity of anxiety orientation and self-handicapping through the multiple mediators of sense of control. Finally, recommendations for coaches related to training and preparation for competition are discussed.

Abstract
PURPOSE To determine whether there is an association between external match load and contextual factors on subjective wellness in the days before and after Australian Rules football match play. METHODS A total of 34 elite male Australian football players completed a subjective wellness questionnaire in the days leading into the match (-3, -2, and -1 d), the day of (match day), and the days after each match (+3, +2, and +1 d). Players subjectively rated each item (mood, energy, stress, leg heaviness, muscle soreness, sleep quality, hours slept, and total wellness [a sum of the total response score]) on a visual analog scale ranging from 1 to 10, with 1 representing the negative end of the continuum. External load during competitive matches was quantified using accelerometer-derived PlayerLoad, and running activity was quantified using global positioning system technology across 2 competitive seasons. The relationships between perceptions of wellness (within-individual z score), external match load, and contextual factors (match result, match location, and between-matches recovery duration) were analyzed using linear mixed models. RESULTS Mixed-effect linear models revealed trivial effects of match-day wellness z score on subsequent external match load metrics. Match result (win) and PlayerLoad in the anteroposterior vector (au·min-1) were associated with an increased (estimate ± SE: 0.30 ± 0.13 z score) and reduced subjective wellness (-0.15 ± 0.06 z score), respectively. CONCLUSION The results of this study suggest that prematch perceived wellness does not relate to external match load in elite Australian football players. The between-matches microcycle length appears to be sufficient to restore perceived wellness to values that do not affect the subsequent external match loads.

Abstract
BACKGROUND/AIM Combat sports might result in injuries to the face and teeth. However, it is unclear how often they occur and which sports presents the highest rates. The aim of this study was to investigate the prevalence of dentofacial injuries in combat sports participants. MATERIAL AND METHODS A systematic review was performed. Six main electronic databases and three grey literature databases were searched. Studies were blindly selected by two reviewers based on pre-defined eligibility criteria. Studies that evaluated the prevalence of dentofacial injuries (teeth, alveolar bone, jaw, lips, and/or cheekbones) among combat sports participants were considered eligible. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The software r statistics version was used to perform all meta-analyses. Cumulative evidence of the included articles was evaluated using GRADE criteria (Grading of Recommendations Assessment, Development and Evaluation). RESULTS From 1104 articles found on all databases, 27 were finally included. Eighteen studies were judged at low, seven at moderate, and two at high risk of bias. The following sports were investigated: boxing, capoeira, fencing, jiu-jitsu, judo, karate, kendo, kickboxing, kung fu, muay thai, sumo, taekwondo, wrestling, and wushu. Results from the meta-analysis suggested a dental pooled prevalence of 25.2% (12.3%-40.8%, i2 = 100%) and dentofacial pooled prevalence of 30.3 (18.1%-44.1%, i2 = 100%). Considering the sports' categories individually, jiu-jitsu had the highest pooled prevalence of dentofacial injuries (52.9% [37.9%-67.8%, i2 = 92%]), while judo was the sport with the lowest pooled prevalence (25.0% [7.6%-48.2%, i2 = 98%]). Among Panamerican sports, boxing had the highest prevalence of dental injuries (73.7% [58.7%-86.3%, i2 = 0%]). For dentofacial injuries, the GRADE criteria were considered low. CONCLUSIONS Overall pooled prevalence of dentofacial injuries in combat sports was approximately 30%. Raising awareness regarding the frequency of these injuries might encourage the use of protective devices and reduce complications related to these incidents.

Hormonal and emotional responses to competition using a dyadic approach: Basal testosterone predicts emotional state after a defeat. Physiol Behav 2019; 206:106-117. [PMID: 30928410 DOI: 10.1016/j.physbeh.2019.03.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2018] [Revised: 03/21/2019] [Accepted: 03/26/2019] [Indexed: 11/21/2022]
Abstract
The present study analyzes the testosterone (T), cortisol (C) and emotional response in competitive interactions between dyads, as well as the relationship between basal T and the emotional response. Seventy-two men and women (36 dyads) participated in same-sex dyads in a face-to-face laboratory competition, and thirty-two men and women (16 dyads) carried out the same task in a non-competitive condition. Salivary samples (5 ml of saliva, plastic vials) were provided at three time points (baseline, task, and post-task), and subsequently T (pg/ml) and C (nmol/L) concentrations were measured using ELISA method. Participants completed self-reported measures of emotional valence, emotional arousal and perceived dominance by means of the Self-Assessment Manikin (SAM), at three time points (pre-task, task, and post-task). Two-level crossed Multilevel Models (MLM) showed a participants' stability in C (Mean ± SEM: baseline: 3.84 ± 0.28, task: 2.92 ± 0.28 and post-task: 2.62 ± 0.3), emotional valence (pre-task: 4 ± 0.06, task: 3.66 ± 0.1 and post-task: 3.84 ± 0.09), arousal (pre-task: 3.29 ± 0.09, task: 3.83 ± 0.09 and post-task: 3.38 ± 0.1) and dominance (pre-task: 3.28 ± 0.08, task: 3.4 ± 0.1 and post-task: 3.44 ± 0.09) values, which in the case of emotional valence and dominance was modulated by time-point, outcome and sex. Furthermore, analyses revealed that opponents' C, arousal and dominance values at one time-point influenced participants' values at the following time-point modulated by outcome, sex and time-point. Moreover, MLM indicated that in loser men, individuals higher in basal T (126.31 ± 6.4) displayed higher negative emotional valence after the defeat (post-task: 3.6 ± 0.21), while in women basal T (99.78 ± 12.6) was not significantly related to post competition emotional valence. These findings reinforce the importance of studying the relationship between hormonal and psychological changes in dyadic competition, and confirm that men and women differ in their psychophysiological responses to competition.

Salivary testosterone concentration, anxiety, perceived performance and ratings of perceived exertion in basketball players during semi-final and final matches. Physiol Behav 2019; 198:102-107. [PMID: 30365978 DOI: 10.1016/j.physbeh.2018.10.008] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2018] [Revised: 08/27/2018] [Accepted: 10/14/2018] [Indexed: 11/20/2022]
Abstract
The aim of this study was to examine the effect of playing semi-final (SFM) and final (FM) matches on salivary testosterone (T) concentration, anxiety, session rating of perceived exertion (session-RPE) and perceived performance (PP) in elite male youth basketball players. Data from 25 players who participated ≥15 min in 6 assessed matches consisting of SFM (n = 3; 1 match for each age-category [U15, U16, and U17]), and FM (n = 3; 1 match for each age-category) were retained for analysis. Saliva sampling was conducted before and after the matches. Video recordings of the matches were conducted to assess the players match involvement (technical and tactical actions). Anxiety (CSAI-2) was assessed before pre-match saliva sampling, and session-RPE and PP were assessed post-matches. A significant increase in T from pre-to-post matches (SFM and FM; F = 24.40, p < .001) was observed, with no effect for condition (F = 1.70, p = .20) or interaction (F = 0.006, p = .93). No significant correlation between changes in salivary T (pre-to-post matches) and match involvement was observed (p > .05). However, a higher anxiety, session-RPE and PP were observed for FM (p < .05). The results of the present study suggest that while rising T in winners might be considered to be a hormonal response to support the expression of high-status signs, regardless of the playoff round (SFM or FM), the T and perceptual responses may be explained based on psychological aspects associated with the environment rather than by the technical demands or player's involvement in the match.

Abstract
The study aimed to investigate physiological and psychological states prior to competition and prior to training in three different demanding activities. Eighteen canoe athletes, 18 street runners and 18 jiu-jitsu fighters were included in this study (n=54). The Competitive State Anxiety Inventory-2 (CSAI-2), salivary cortisol and heart rate variability (HRV) were measured at two time points (pre-training and pre-competition). Somatic anxiety (F1,42 = 15.29, p = 0.0003), HRV (F1,42 = 23.24, p < 0.0001) and salivary cortisol (F1,42 = 22.96, p < 0.0001) were significantly greater at the pre-competition measurement point than at the pre-training point, but without a main effect of the type of athlete on these variables. A main effect of the type of athlete was found on somatic anxiety (F2,42 = 6.58, p = 0.0033), cognitive anxiety (F2,42 = 10.69, p = 0.0002) and self-confidence (F2,42 = 5.42, p = 0.0080). Correlations between most CSAI-2 and physiological parameters were not significant (p > 0.05). In conclusion, the results indicated that both emotional indices and psychophysiological indices of stress are higher before competition than before training, with differences between emotional states between these sports. Although correlations between emotional states and psycho-physiological states before competition and before training were largely non-significant, these findings reinforce the importance of psychological monitoring of athletes in association with traditional physiological markers such as cortisol and HRV in sportive training programmes as complementary resources to improve both competition performance and the training routine.

Abstract
This study examined the effects of competition stage on the salivary concentration of testosterone (T), cortisol (C), alpha-amylase (sAA), and IL-1ß cytokine, perceived performance (PP) and session rating of perceived exertion (session-RPE) in elite youth basketball players (age, 15.8 ± 0.8 yrs.; stature, 190.9 ± 7.9 cm; body mass, 90.0 ± 16.9 kg) from two age-categories (U16; n = 7; U17; n = 7). Two winning playoff matches (FM; playing for the championship; 1 for each age-category) and two winning regular stage matches (RM; 1 for each age category, played against opponents ranked 2nd place), were assessed in the current study. Saliva samples were collected before and after each match and analyzed by ELISA; PP and session-RPE were assessed after each match. The results from the two-way ANOVA (condition; FM and RM) with repeated measures (pre-and post-matches) showed a significant effect for time (increase from pre-to-post matches) in T (F = 7.0, p < .001), C (F = 34.0, p < .001), and sAA (F = 25.0, p < .001), but not for IL-1ß (p > .05). No effect of condition or interaction (FM and RM) was observed on salivary markers. PP was higher for FM, compared to RM (effect size; ES = 0.85), despite no clear difference in session-RPE (ES = 0.22). A higher PP for FM might be associated with the fact that players were no longer concerned about issues linked to social dominance and status threats after FM, but they might be uncertain about their status after RM. Additionally, when playing against a high-level opponent, the players might perceive their opponent as a threat against status stability, regardless of the stage of the competition, which might explain the similar change in salivary neuro-endocrine-immune-related markers.

Abstract
Block periodization (BP) has been proposed as an alternative approach for application in the context of high-level sports. Despite its growing acceptance, there is no empirical evidence of BP adoption in high-level judo athletes. Therefore, this study aimed to compare the maximal strength, muscle power, judo-specific performances, and hormonal concentration changes of state/national level (NG) and international level (IG) judo athletes subjected to BP. Twenty-one elite judo athletes (international level = 10; 21.7±1.9 years, 167.2±7.6 cm, 67.6±9.4 kg, 15.7±1.9 years of practice; national level = 11; 21.9±3.0 years, 167.5±9.1 cm, 71.8±16.5, 15.9±3.0 years of practice) were subjected to 13-week BP training (5-week accumulation phase [ACP], 5-week transmutation phase [TP], and 3-week realization phase [RP]). The judo-specific performance (SJFT) increased as there was observed a decrease in the SJFT index (final heart rate [HR] (bpm) + HR1 min after the test divided by the number of throws) for both NG (effect size [ES] = 0.83) and IG (ES = 0.53) from ACP to TP (p < 0.05). The row exercise maximal strength decreased (p < 0.05; ES = 1.35) after the ACP but returned to the baseline level after the TP, for the whole group (ES = 1.39). The athletes did seem to cope appropriately with the demands of BP, as besides increases in SJFT performance no significant changes were observed for cortisol and testosterone concentrations. This is the first study to demonstrate that judo athletes from different competitive levels subjected to BP improved SJFT, likely due to an appropriate balance between training loads and recovery. Thus, the BP approach may be a useful alternative periodization strategy for high-level judo athletes.

Abstract
This study examined the effect of playing matches against different opponent teams (hard match; HM, medium match; MM, and easy match; EM) on pre-match testosterone concentration (T), pre-to-post match cortisol (C) concentration, and pre-competitive anxiety (CSAI-2 questionnaire) in 20 elite male basketball players. One training session (TS) was also assessed (control condition). Saliva steroids were determined by ELISA. The pre-T concentration was significantly lower for the TS (163±54pmolL-1), compared to the three official matches (EM: 208±82pmolL-1, MM: 213±57pmolL-1, and HM: 218±37pmolL-1) (p<0.05). A significant change in C from pre-to-post was observed for all conditions (TS [5.8±3.7 vs 14.4±9.4ƞmolL-1], EM [10.1±4.9 vs 17.3±10.2ƞmolL-1], MM [13.0±7.4 vs 21.5±8.3ƞmolL-1], and HM [18.9±5.8 vs 31.4±5.3ƞmolL-1] (p<0.05). A higher PRE-C was observed for the HM, compared to TS and EM (p<0.05) and a higher POST-C concentration for the HM was detected, compared to the TS, EM, and MM (p<0.05). A lower anxiety level was observed for the EM (somatic: 15.0±3.7; cognitive: 15.8±4.5 arbitrary units [AU]) compared, to the MM (somatic: 16.4±3.5; cognitive: 17.7±4.0AU) and HM (somatic: 15.8±3.9; cognitive: 18.3±3.9AU) (p<0.05) and a higher self-confidence was observed for the TS (28.9±5.1AU), compared to the HM (26.7±3.0AU) (p<0.05). These results suggest that playing against a high-level opponent may cause a higher psychobiological stress, likely because opponent level may be perceived as threating to the social status in a given hierarchy.

Abstract
BACKGROUND Standardized communication frameworks are believed to help students feel more confident and less anxious about handover reports. One of the handover communication frameworks being used in nursing programs was the ISBARR framework (Identify, Situation, Background, Assessment, Recommendation, and Repeat). The aim was to explore whether learning the ISBARR framework affected nursing students' perceived anxiety and confidence levels associated with handover reports. METHOD The study tested null hypotheses by analyzing pre- and posttest data collected with the Competitive State Anxiety Inventory-2 (CSAI-2) survey. Three qualitative questions were included in the posttest to compare with the quantitative data. Statistical significance was set at p = .02. RESULTS The results revealed that learning the framework had a strong effect in reducing the perceived somatic anxiety levels, a medium effect on increasing perceived confidence levels, and a medium effect in reducing the perceived cognitive anxiety levels. CONCLUSION Findings suggested that learning the standardized framework may help to address students' perceived anxiety and confidence levels associated with handover reports and generate a mental picture of handover reports.

Abstract
Salivary biomarkers have shown to be useful to assess physiological stress in football, but their relationship with physical performance is unknown. The aims of this study were to investigate the effect of a football match on salivary cortisol, testosterone and immunoglobulin A (IgA) concentrations in elite footballers, and to examine the relationship of physical performance during the match to these biomarkers. Nine elite football players were assessed before, during and after a friendly international match. Physical performance during the match was measured by time-motion analysis, whilst salivary cortisol, testosterone and IgA were measured before and 10 min post-match. The results showed that players covered an average of 9463 ± 458 m during the match. Salivary cortisol did not change post-match. Testosterone and IgA concentrations decreased by 30.6% and 74.5%, respectively. The testosterone/cortisol (T/C) ratio decreased by 64.2% after the match. Changes in testosterone concentrations correlated (r = 0.85) with distance covered. Pre- and post-match testosterone levels correlated with post-match IgA concentrations (r = 0.8 and 0.89, respectively). These results suggest that a football match induces catabolic stress as indicated by the decreased T/C ratio. It seems that footballers with smaller decreases in testosterone levels covered more distance and decreased their immune function less.
