Moving forward through the process, rehabilitation tends to gradually get more specific and the clinical setting is often traded for a sport-specific setting. The emphasis during the last phase of rehabilitation is on

This study represents a first step in the development and validation of a measure of sport-specific self-acceptance. Phase 1 of this study involved instrument design and pilot testing. In Phase 2 a random sample of Division I collegiate athletes (N=131) were asked to complete the Self-Acceptance Scale for Athletes (SASA) as well as measures of general self-acceptance self-esteem, stability of self-concept, and sport-specific self-description (i.e., perceived competence/adequacy). Test-retest coefficients ranged from 62 to .75 and alpha coefficients ranged from .58 to .80. Factor analysis suggests two factors, independence of self-regard and self-accepting self-regard representing the two dimensions of self-acceptance measured in the SASA. Scores on the SASA have moderate correlations with general self-acceptance, self-esteem, and stability of self-concept. A significantly stronger relationship between self-esteem and perceived competence/adequacy than between self-acceptance and perceived competence/adequacy suggests that the SASA is able to discriminate between these closely related constructs

The purpose of this study was to examine whether a video-based warm-up could provide an acute performance benefit to response time for athletes in a sport-specific agility task. In addition, 2 learning strategies, explicit and implicit, were compared for their effectiveness in facilitating an improvement in sport-specific agility. Thirty representative male junior rugby union players (age 14–16 y, mean age 14.6 ± 1.09 y) were placed in 3 experimental groups (explicit, implicit, and control) and completed 2 intervention sessions. Testing sessions included preintervention testing, completion of the video-based warm-up intervention, and postintervention testing. A 3D motion-analysis system was used to assess response time in the testing battery. The athletes’ response times on the pre- to postintervention tests were compared to determine the effectiveness of the video-based warm-up. A 2-way general linear model with repeated-measures analysis indicated that both the explicit (P = .030, d = 0.28) and implicit (P = .049, d = 0.33) groups significantly improved their response time by the intervention compared with the control group (P = .367, d = 0.08). The mean postintervention response time for the explicit group improved by 19.1% (from 0.246 s pre to 0.199 s post), and the implicit group improved by 15.7% (from 0.268 s to 0.226 s). Findings suggest that a video-based warm-up may provide an acute benefit to sport-specific agility performance for junior athletes.
