Specific futsal training program can improve the physical performance of futsal players

Physical Training Considerations for Futsal Players According to Strength and Conditioning Coaches: A Qualitative Study

The professionalization of futsal requires greater physical demands on players, requiring strength and conditioning coaches to manage loads, optimize performance, and prevent injuries. This study aimed to describe the current practices of high-level strength and conditioning coaches and determine the elements needed to optimize their performance. Two video-recorded focus groups consisting of eight strength and conditioning coaches from the Spanish futsal league's first and second divisions were transcribed, translated, and analyzed using a content analysis approach with open-ended questions on physical preparation and current practices. Results showed that strength and conditioning coaches prioritized five main areas: (1) competitive demands, (2) training load control and monitoring, (3) injury risk mitigation strategies, (4) contextual factors and interpersonal relationships, and (5) training methodologies to optimize performance. However, they also claim to deal with several limitations such as lack of time, limited resources and access to facilities, insufficient staff, problems related to combining sport with other activities (e.g., work), or the difficulty to individualize, which limits the optimization of their practices. Based on these findings, practical applications include implementing neuromuscular and strength training sessions at least twice a week, using cost-effective load monitoring tools (e.g., RPE and wellness questionnaires) to manage workloads, individualizing training programs to address the specific demands and characteristics of each player, and fostering close multidisciplinary collaboration to optimize performance and reduce injury risks. These insights can guide current and aspiring strength and conditioning coaches toward optimized practices. This study can assist novice strength and conditioning coaches in identifying the key focus areas of elite physical trainers and understanding their challenges and limitations, fostering collaboration among sports professionals to create a more optimized environment.

3-min All-out Test to Evaluate Aerobic and Anaerobic Indexes in Court Team Sports

This study aimed to test the reproducibility of the 3-min all-out effort applied using shuttle running and compare its values to aerobic parameters. On the first day, 14 futsal players underwent an exhaustive test to determine the maximal incremental speed (MIS) and anaerobic threshold (AnT). On the second day, the participants performed the 3-min all-out effort (n=14), which was repeated after 48 h (third day) to test its reproducibility (n=11). Peak oxygen consumption (V̇ O2PEAK) and peak blood lactate concentrations ([La-]) were determined from 3-min all-out efforts performed through a 20-m shuttle run on the official court. The distance covered, mean speed, and critical speed (CS) during the 3-min all-out presented direct relationships with aerobic parameters determined through the incremental test (r>0.62). The distance covered above CS (D') presented a direct relationship with peak lactate concentrations induced by a 3-min all-out effort (r=0.81). Despite the acceptable levels of reproducibility observed for most of the 3-min all-out variables, the minimal detectable change for D' was high (72%). Our results demonstrated the potential use of mean speed to evaluate aerobic fitness. However, the applicability of the 3-min all-out shuttle run test to monitor training adaptations should be avoided, at least in nonexperienced athletes.

Trends in anthropometric and somatotype profiles of Brazilian female futsal players: a 20 year study

This study describes the anthropometric measurements and somatotype of the elite female futsal players from Brazil in 2021 and analyse the changes and trends over time in these physical characteristics. Data were collected from the 396 female futsal players, of whom; 169 players were assessed in 2021 then compared to those assessed in 2001 (n=112) and 2011 (n-115). Anthropometric measurements, including body weight, height, breadths, girths, and skinfolds were assessed. The somatotype was calculated and graphically represented. The changes between 2021 and the previous years were analysed using ANOVA and multiple linear regression. A jointpoint regression was performed to verify the annual percentage change. The comparison between 2021 data versus the other time points showed a higher age and lower fat content (2001: 22.7 ± 5.1 BF%; 2011: 22.2 ± 5.2 BF%; 2021: 19.0 ± 5.1 BF%). Players from 2021 had higher tensed arm and relaxed calf girths. All the positions, excluding pivots, significantly decreased their body fat units between 2021 and 2001 (goalkeeper: b=-4.49; defender: b=-2.78; winger: b=-4.48). Over the last 20 years, body fat reduced, and tensed arm and relaxed calf girths increased, suggesting an increase in fat-free mass content from the limbs.

Differences in Psychological Variables and the Performance of Female Futsal Players according to Playing Position, Match Result and Menstruation

Futsal performance has been extensively investigated in previous studies, demonstrating that the psychological state of the players or the playing position condition performance. However, research with female indoor soccer players is scarce; therefore, menstruation has not been considered as a determinant aspect for performance in females. Previous research has shown the influence of menstruation on the psychological state and performance of players of different sports; however, there is no known research on female futsal players. For this reason, the aims of the present research were to establish the differences in pre-match psychological variables and offensive performance as a function of playing position, match result and menstruation. A total of 132 s division Spanish players participated in the research. All participants completed the Questionnaire of Psychological Needs of the Athlete-15, and their regular league matches were recorded and subsequently analyzed to determine their offensive performance. The results showed differences according to playing position: pivots and closers showed greater motivation than wings, while the pivots showed greater activation and shots on goal than the wings and closers. Regarding match results, pivots demonstrated more shots on goals than closers only when the match was lost. In addition, the motivation and activation of the pivots, as well as the number of shots on goal, were higher than that of the wings and closers only when they were not menstruating.

Leg dominance and performance in change of directions tests in young soccer players

The present study aimed to examine the influence of leg dominance on the change of direction (COD) performance. In this study participated 94 healthy young highly trained male soccer players belonging from two categories (n = 27 vs. n = 67; 14.81 ± 0.40 vs. 16.64 ± 1.25 years of age; 170.61 ± 5.61 vs. 173.73 ± 7.19 cm of height; 64.74 ± 8.44 vs. 66.70 ± 7.95 kg of weight, for U16 and U18, respectively). Fitness assessments were performed two times in a period of three months, and included: (1) anthropometry measures, (2) 30–15 IFT, (3) 10-m sprint test, (4) 505-COD test, 90° COD test and cross-over hop test. A paired sample t-test was performed to evaluate the asymmetries at the intragroup level in each of the COD’s tests. A symmetry index was used to analyse the asymmetries between categories, and an independent sample t-test was used to compare the variability between the two categories in each of the three tests performed. The effect size was also evaluated. Analysis demonstrated that evidence a trend for a better performance with the preferred leg in the cross-over hop and 505-COD tests, and with the non-dominant leg in the 90° COD. However, in the intragroup analysis, only the 505-COD test registered differences, and no differences were notice din the intergroup comparison. Only in the 505-COD test the percentage of variability (CV) was statistically significant (7.03 ± 4.18% vs. 4.03 ± 2.02% from U16 and U18, respectively). In sum, bilateral differences were noticed in the intragroup comparison, although only in 505-COD test the leg dominance showed to influence performance. In the intergroup analysis any difference was noticed between age categories.

Reliability and Validity of a Novel Futsal Special Performance Test Designed to Measure Skills and Anaerobic Performance

PURPOSE

To examine the validity and reliability of a novel futsal special performance test (FSPT) as a measure of futsal performance and skills.

METHODS

Thirty-six futsal players with different levels of experience were recruited and divided into 2 groups (elite and nonelite). Players participated in 4 sessions (at least 7 d apart): (1) familiarization session, (2) anaerobic power (Wingate test), (3) FSPT trial 1, and (4) FSPT trial 2. The FSPT was carried out on a futsal court (wooden sprung floor) and skills such as dribbling, rotation, long and short passing, and shooting were examined. Content validity was assessed by 6 experienced futsal coaches and instructors.

RESULTS

There was a significant correlation between FSPT and various aspects of anaerobic power (r = .5-.91; P ≤ .001). Moreover, significant large correlations were observed between test and retest of FSPT (r = .77; 95% confidence interval [CI], .56-.98; P ≤ .001). All instructors and coaches confirmed the content validity. There was high interrater reliability of the FSPT (r = .89; 95% CI, .85-.93; P < .001). FSPT total time (P = .001), penalty time (P = .022), and performance time (P = .001) were superior in elite relative to nonelite players. Anaerobic power was greater in elite players (P < .001).

CONCLUSION

The results support the use of the FSPT to assess futsal players' performance in conjunction with skill and anaerobic fitness.

Generic vs. small-sided game training in futsal: Effects on aerobic capacity, anaerobic power and agility

The aim of this study was to compare a 6-week conditioning training program based on Small Sided and conditioning game (SSG) and based on traditional and generic fitness the aerobic capacity, anaerobic power and agility of young futsal players. It was also aim of this study to compare the variations on the internal load markers (heart rate and perceived exertion) between both training programs. Twenty youth players (age: 18.6 ± 0.5 years old) were randomly assigned to SSG (n = 12) and generic fitness training (GFT) group (n = 8). Each group performed workouts with equal duration and intensities. Participants completed a VO2max treadmill test, the Wingate test and an agility test pre and post training period. Training heart rate and Rate Perceived Exertion (RPE) were used as internal load markers during the training program. There was a significant difference in training load (RPE) between two groups in all types of training but not in the heart rate. Despite significant improvements (p < .05) from pre to post tests in all measured indicators except minimum power, there was no significant changes between groups for agility, anaerobic, and aerobic parameters (p > .05). SSG-based program provided a similar heart rate stimulus on players comparing to GFT program and both programs meaningfully improved the fitness parameters of the young futsal players. Moreover, SSG-based program also resulted in better technical performance, thus representing an effective alternative to generic fitness training for the development of aerobic capacity and anaerobic power in futsal.
