Purpose:

To investigate the effects of combining cold-water immersion (CWI), full-body compression garments (CG), and sleep-hygiene recommendations on physical, physiological, and perceptual recovery after 2-a-day on-court training and match-play sessions.

Methods:

In a crossover design, 8 highly trained tennis players completed 2 sessions of on-court tennis-drill training and match play, followed by a recovery or control condition. Recovery interventions included a mixture of 15 min CWI, 3 h of wearing full-body CG, and following sleep-hygiene recommendations that night, while the control condition involved postsession stretching and no regulation of sleeping patterns. Technical performance (stroke and error rates), physical performance (accelerometry, countermovement jump [CMJ]), physiological (heart rate, blood lactate), and perceptual (mood, exertion, and soreness) measures were recorded from each on-court session, along with sleep quantity each night.

Results:

While stroke and error rates did not differ in the drill session (P > .05, d < 0.20), large effects were evident for increased time in play and stroke rate in match play after the recovery interventions (P > .05, d > 0.90). Although accelerometry values did not differ between conditions (P > .05, d < 0.20), CMJ tended to be improved before match play with recovery (P > .05, d = 0.90). Furthermore, CWI and CG resulted in faster postsession reductions in heart rate and lactate and reduced perceived soreness (P > .05, d > 1.00). In addition, sleep-hygiene recommendations increased sleep quantity (P > .05, d > 2.00) and maintained lower perceived soreness and fatigue (P < .05, d > 2.00).

Conclusions:

Mixed-method recovery interventions (CWI and CG) used after tennis sessions increased ensuing time in play and lower-body power and reduced perceived soreness. Furthermore, sleep-hygiene recommendations helped reduce perceived soreness.

The present study used a mixed methods approach to evaluate the usage and perceived effectiveness of a 12-month coping intervention. Twelve junior national netball players followed an intervention that had two objectives: 1) to encourage the use of future-oriented coping across goal-oriented contexts and 2) to facilitate resource accumulation and maintenance by developing coping related competencies. Mentors and players maintained reflective diaries throughout the intervention and were contacted via telephone or e-mail every 2–3 months. In addition, players completed the Brief COPE measure at 1, 6, and 12 months. Eight players and 8 mentors completed postintervention interviews. Data indicated that following completion of the intervention, players perceived themselves to have a better understanding of when and how to use future-oriented coping. They also perceived enhanced psychosocial resources, and a more flexible approach toward goal pursuits. Recommendations for future research developments and the evaluation of coping interventions are presented.

Background:

The purpose of this study was to implement and assess the impact of a person-centered, feel-based self-regulation intervention on the stress, burnout, well-being, and self-regulation capacity of eight university student-athletes experiencing burnout. This was warranted given the negative outcomes associated with athlete burnout, the scarcity of burnout research focusing on student-athletes, and the lack of intervention research addressing burnout in sport.

Method:

A mixed methods design including questionnaires administered at four time points during the athletic season, pre- and postintervention interviews, and multiple intervention sessions was used.

Results:

Repeated-measures ANOVAs revealed that stress and burnout levels significantly decreased, and well-being and self-regulation capacity levels significantly increased as the intervention progressed. The qualitative data supported these findings.

Conclusion:

It appears that university student-athletes participating in this type of intervention can learn to effectively manage themselves and their environment to reduce adverse symptoms and improve optimal functioning.

Physical activity experiences of 12 age-matched boys with and without attention-deficit hyperactivity disorder (ADHD) were explored by converging information from Test of Gross Motor Development-2 assessments and semistructured interviews. The knowledge-based approach and the inhibitory model of executive functions, a combined theoretical lens, enabled the description of similarities and differences in experiences that emerged during interviews. Skill assessments indicated boys with ADHD were not as proficient movers as their peers without ADHD. Thematic analysis revealed that boys with ADHD reported playing with friends, paid little attention to detail, possessed superficial knowledge about movement skills, and expressed many negative feelings about physical activity. Task-specific interventions and a wider range of mixed methods research are recommended for future research studies in ADHD.
