Stressors Associated with Professional Australian Rules Football Athletes Across a Competitive Season

Abstract

Objective: This study explored psychophysiological stress in professional Australian Rules football athletes across the course of one competitive season.

Methods: A sample of eight players listed with one professional Australian football club participated in this study. Each week during the competitive season (22 weeks), players self-reported their general fatigue and sleep using a paper-based scale, as well as providing a salivary cortisol measure. Testing occurred 48-hours after competition. Participants’ weekly performance rating scores based on a points system metric of players’ data obtained during competitive matches were also recorded by the club each week.

Results: A significant inverse relationship was observed between cortisol and performance ratings, sleep and fatigue, and sleep and performance ratings. There was a significant predictive relationship observed, with cortisol levels and performance rankings (R² = .35, F (6,74) = 7.06, p<.001). There was no significant relationship between performance and fatigue or performance and sleep.

Conclusions: This study shows a significant relationship between performance outcomes and psychophysiological stress in professional Australian football players. Professional clubs should look towards objective assessment protocols to measure athlete psychological stress to enhance current practice of self-report stress measures.

The Influence of COVID-19 Upon Perceptions of Parent Identity and Role Among Youth Sport Spectators

ABSTRACT

Parent experiences in youth sport settings during the COVID-19 pandemic are a notable and understudied phenomenon. Parents had varied experiences as a result of safety mandates and protocols that limited physical presence and engagement in their child’s sports activities. These limitations proved to be an emotional challenge for parents – balancing the responsibilities of protecting the safety of their families and providing sports experiences to promote both normalcy and acquire the life skills gained from sports participation in a fluid environment. In some instances, parents engaged in virtual spectating experiences which sought to minimize physical risks associated with COVID-19, but also did not require their physical presence to participate. Research on the virtual experience of parents is novel and from a sample of 112 parents across youth sport sectors in 18 states how the spectating modality influenced parental roles and identities was examined. Virtual spectating experiences reflected many challenges for parents, but also prompted much gratitude for allowing continued engagement in their child’s sports activities. This exploratory research prompts larger questions urging sport-based professionals to examine the influences of spectating modalities on experiences of parents. The authors captured retrospective parent reactions to their personal spectating experience and generated a grounded theory diagram to demonstrate relationships between factors shaping the parent identity and role in this context. Implications for sport-based professionals are discussed.

Changes in Vertical Jump Height and Sprint Time During a Congested Match Schedule in Youth Female Soccer Players

Abstract

Purpose: The purpose of this study was to examine changes in jump height and sprint time and to assess the relationship between relative changes in jump height and accumulated training load during a congested match schedule in youth female soccer players. Methods: This study included data from 14 youth female soccer players who performed countermovement jump testing pre- and post-match, post-tournament, as well as sprint testing pre- and post-tournament. A one-way repeated measures ANOVA was conducted to compare changes in jump height over the course of the tournament. A paired sample t-test was performed to compare sprint time between pre- and post-tournament, and Pearson product moment correlations were used to determine the relationship between percent change in jump height and accumulated training load. Results: Jump height decreased significantly (p < 0.001) between time periods during the tournament, and sprint time increased significantly (p = 0.001). There was no significant relationship between percent change in jump height and accumulated training load. Conclusion: This study found that jump height decreased over the course of the tournament and there was a significant increase in sprint time from pre- to post-tournament. Applications in Sport: These results suggest that appropriate recovery strategies and training are needed to assist players in coping with the demands of a congested youth soccer schedule.

Servant Leadership and the Relationship to Autonomy, Competence, and Relatedness in Division I Athletic Departments

ABSTRACT

Purpose

The purpose of this study was to explore the relationship between observed servant leadership behaviors of Division I athletic directors and self-reported basic work-related psychological needs satisfaction of Division I administrative (e.g., non-coaching) athletic department employees. This study examined the relationship between servant leadership behaviors in Division I athletic directors and the three elements of basic work-related psychological needs satisfaction including autonomy, competence, and relatedness.

Methods

A sample of athletic department employees in 35 randomly selected Division I athletic departments (n = 230) were sent an electronic survey via email that included questions on demographics, the seven-item Servant Leadership Scale (SL-7), and the 12-item adapted Work-Related Basic Need Satisfaction Scale (W-BNSA).

Results

The results of this study revealed a statistically significant, positive relationship exists (p < .001) with observed servant leadership behaviors in athletic directors and the athletic department employees’ work-related psychological needs of autonomy, competence, and relatedness.

Conclusions

This finding supported the view that greater levels of servant leadership behaviors in Division I athletic directors were associated with greater work-related basic psychological needs satisfaction of Division I athletic department employees.

Applications in Sport

The results of this research provide an opportunity for athletic directors at the highest level of intercollegiate competition (Division I) to adopt a leadership style that can contribute to the three components of basic psychological needs satisfaction in their employees.

Relationships Among Muscle Characteristics and Rowing Performance in Collegiate Crew Members

Abstract

Purpose: The purpose of this study was to explore the relationships among measurements of muscle quality and rowing performance in college-aged club rowers. Methods: Ten men and women (mean ± SD: age: 22.1 ± 4.0 years; ht: 180.5 ± 8.3 cm; wt: 79.0 ± 13.5 kg) volunteered to participate in this study. Ultrasound images were collected at 50% thigh length in a transverse plane to quantify muscle size. The sum cross-sectional area (mCSA) of these muscles was reported. Bioelectrical impedance analysis (BIA) was conducted to predict fat-free mass (FFM) and estimate total leg lean mass. One-repetition maximum leg press (LP_MAX) was recorded as well as vertical jump (VJ_HT; cm). Lastly, participants completed a 2,000m time trial on the rowing ergometer, where the 500m average split was used in analyses. Pearson’s product moment correlations were calculated across all variables and backwards stepwise linear regression was completed using VJ_HT, LP_MAX, FFM, and mCSA as possible predictors of 500m performance. Results: The correlations coefficients among recorded variables were all very high and significant (r = 0.867-0.950; p = 0.001-0.04). The regression analysis indicated VJ_HT was a significant predictor of 500m time trial performance (R²=0.903; p<0.05). Conclusions: Although rowing may often be considered an endurance sport, the single best predictor of and the strongest correlation to time trial performance is vertical jump height as an index of power. Applications in Sport: Emphasis on plyometric training may serve as one of the most important aspects of athlete development beyond rowing form and mechanics, more so than strength or hypertrophy in collegiate rowers.
