This study examined the relationship between perceived coaching behaviors, coping strategies during a sport competition, and sport achievement. A prospective design was used in which 80 athletes from individual sports completed measures of perceived coaching behaviors two days before a competition (Time 1) and measures of coping and sport achievement within three hours after a sport competition (Time 2). As expected, results of multiple regressions indicated that supportive coaching was a positive predictor of task-oriented coping and sport achievement whereas unsupportive coaching was a positive predictor of disengagement-oriented coping. Both types of coping were significantly associated with sport achievement. Task-oriented coping was a significant partial mediator in the relation between supportive coaching and sport achievement. This study, which contributes to both the coaching and coping literatures, highlights the role of supportive coaching behaviors in the initiation of effective stress management during sport competitions.

The association between androgens and competition in women has been understudied compared with men. The current study examined the link between testosterone (T) and competition in elite female athletes, using a sample of female wrestlers that included athletes competing at both the national and international level. In a repeated-measures design, saliva samples were collected before and after wrestling bouts, with comparable samples of wins and losses, and subsequently analyzed for T. Study results showed a 22% increase in circulating bioavailable T from pre-to postbout, F(1, 12) = 9.71, P = .009. There was no significant difference in T between win or loss outcomes. These findings—showing a link between individual head-to-head competition and T in women—demonstrate that women’s androgenic responses to environmental contexts are dynamic and may be an important factor to address in research on competitive performance.

Athletes are required to continuously make decisions during their competition about how and when to invest their available energy resources. 1 This goal-directed regulation of their exercise intensity is also known as pacing. 2 However, the underlying mechanisms behind this decision

Elite athletes are exposed to a high level of both physiological and psychological stress leading up to and on the day of competition and therefore look to utilize a range of different strategies to gain and maintain a competitive edge. 1 One strategy that elite athletes use to counteract sleep

Purpose:

To investigate the patterns and performance of substitutions in 18 international 15-a-side men’s rugby union matches.

Methods:

A semiautomatic computerized time–motion system compiled 750 performance observations for 375 players (422 forwards, 328 backs). Running and technical-performance measures included total distance run, high-intensity running (>18.0 km/h), number of individual ball possessions and passes, percentage of passes completed, and number of attempted and percentage of successful tackles.

Results:

A total of 184 substitutions (85.2%) were attributed to tactical and 32 (14.8%) to injury purposes respectively. The mean period for non-injury-purpose substitutions in backs (17.7%) occurred between 70 and 75 min, while forward substitutions peaked equally between 50–55 and 60–65 min (16.4%). Substitutes generally demonstrated improved running performance compared with both starter players who completed games and players whom they replaced (small differences, ES –0.2 to 0.5) in both forwards and backs over their entire time played. There was also a trend for better running performance in forward and back substitutes over their first 10 min of play compared with the final 10 min for replaced players (small to moderate differences, ES 0.3–0.6). Finally, running performance in both forward and back substitutes was generally lower (ES –0.1 to 0.3, unclear or small differences) over their entire 2nd-half time played compared with their first 10 min of play. The impact of substitutes on technical performance was generally considered unclear.

Conclusions:

This information provides practitioners with practical data relating to the physical and technical contributions of substitutions that subsequently could enable optimization of their impact on match play.
