Does Physical Conditioning Influence Performance Attenuation and Recovery in Gaelic Football?

Relationship Between Objective and Subjective Markers of Muscle Recovery in Professional Handball Players

PURPOSE

To evaluate the relationship between items of the Short Recovery and Stress Scale (SRSS) related to physical stress and recovery and the biomarker creatine kinase (CK) in professional handball.

METHODS

CK and SRSS items (physical performance capability, overall recovery, muscular stress, and overall stress) were assessed in an observational study of 16 adult male professional handball players from a team in the highest German league during the 2019-20 preseason. Their preseason training schedule included several microcycles, each consisting of 3 consecutive days of intense training followed by a rest day. On 5 of these rest days, when players were classified as nonrested, and the 5 immediately following days, when players were classified as rested, players completed the SRSS between 8:00 and 9:00 AM, followed by blood sampling. Correlations between SRSS items were performed using Kendall τ. The relationship between each SRSS item and CK levels over time was examined using a mixed-effects model with a random intercept.

RESULTS

CK levels and SRSS stress items were significantly higher and SRSS recovery items were significantly lower in nonrested players. SRSS items were significantly positively or negatively correlated (all items: P < .001) and showed a significant effect indicating lower CK levels in rested players (all items: P ≤ .001; ηp2=.1-.32).

CONCLUSIONS

The investigated SRSS items may be a viable option for assessing muscle recovery in adult male professional handball players in a cost-effective and noninvasive manner. They can be used as a single monitoring tool or as part of a multimodal approach.

A new database of the analysis of the physiological needs in amateur female basketball during official matches

The PHYAFB database is a valuable resource for studying the physiological demands of female amateur basketball players during high-stress official games. It contains heart rate data from ten players aged 18 to 26, collected during ten crucial relegation phase matches, with 348,232 HR samples in CSV and Excel formats for easy access and analysis. The database includes Python source code for initial examination. The primary aim of the PHYAFB database is to provide a useful reference for other teams facing similar situations. Furthermore, the database represents a unique and valuable resource for sports scientists, coaches, and trainers seeking to comprehend the physiological demands of female basketball players during official competitions. Through the analysis of heart rate data, coaches and trainers can identify the intensity and duration of physical activity during games, enabling the development of more effective training programs. Additionally, the database can be used to compare the physiological demands placed on male and female basketball players or to investigate the impact of different game strategies on player performance.

The Use of Recovery Strategies in Gaelic Games: A Mixed-Methods Analysis

PURPOSE

This study investigated Gaelic games players' (1) use of postexercise recovery strategies; (2) recovery strategies according to sport, biological sex, and playing standard; and (3) recovery strategy periodization.

METHODS

Participants were a total of 1178 Gaelic players (n = 574 female), age 24.6 (6.6) years. These players completed a questionnaire investigating postexercise recovery strategies. Participants were further dichotomized by playing standard into developmental (club/collegiate; n = 869) and national (intercounty; n = 309) levels and by sporting codes: Gaelic football (n = 813), Camogie/hurling (n = 342), and handball (n = 23).

RESULTS

Active recovery (90.4%), cold temperature exposure (79.5%), regular sleep routine (79.1%), strategic nutritional intake (72.3%), and massage (68.8%) were the most commonly used recovery strategies. Recovery strategy use was periodized by 30% of players. A significantly larger proportion of national-level players apply cold temperatures (86.7% vs 73.1%; P = .001) and nutritional strategies (80.1% vs 69.2%; P = .012) when compared with developmental players. A significantly larger proportion of female players have a regular sleep routine (82.6% vs 75.1%; P = .037), apply external heat (63.4% vs 48.5%; P = .002), and perform stretching (76.5% vs 66.4%; P = .002) postexercise when compared with male players. A significantly larger proportion of male players employ nutritional strategies (77.6% vs 67.5%; P = .007) and consume a combination of protein and carbohydrate (62.1% vs 28.0%; P < .001) postexercise when compared with female players.

CONCLUSION

Gaelic games players regularly implement a range of postexercise recovery strategies in an attempt to expediate the return of performance capacity and psychophysiological status to preexercise levels. The current findings may support practitioners who seek to prescribe effective and periodized recovery interventions targeting optimized preference/compliance.
