  • Effectiveness of post-match recovery strategies in rugby players
  • 2006
  • Ingår i: British Journal of Sports Medicine. - 0306-3674 .- 1473-0480. ; 40, s. 260-263-

    • Objectives: To examine the effectiveness of four interventions on the rate and magnitude of muscle damage recovery, as measured by creatine kinase (CK).Methods: 23 elite male rugby players were monitored transdermally before, immediately after, 36 hours after, and 84 hours after competitive rugby matches. Players were randomly assigned to complete one of four post-match strategies: contrast water therapy (CWT), compression garment (GAR), low intensity active exercise (ACT), and passive recovery (PAS).Results: Significant increases in CK activity in transdermal exudate were observed as a result of the rugby match (p<0.01). The magnitude of recovery in the PAS intervention was significantly worse than in the ACT, CWT, and GAR interventions at the 36 and 84 hour time points (p<0.05).Conclusions: An enhanced rate and magnitude of recovery was observed in the ACT, CWT, and GAR treatment groups when compared with the PAS group. Low impact exercise immediately post-competition, wearing compression garments, or carrying out contrast water therapy enhanced CK clearance more than passive recovery in young male athletes.

  • The relationship between changes in interstitial creatine kinase and game-related impacts in rugby union
  • 2008
  • Ingår i: British Journal of Sports Medicine. - 0306-3674 .- 1473-0480. ; 42:3, s. 198-201

    • Aim: The primary purpose of this study was to investigate the relationship between the pre-game to post-game changes in creatine kinase concentration ([CK]) and impact-related game statistics in elite rugby union players.Methods: Twenty-three elite male rugby union players each provided interstitial fluid samples obtained via electrosonophoresis (ESoP) 210 min before and within a maximum time of 30 min after up to five rugby union games. Specific game statistics that were deemed to be important in determining the relationship between impact and [CK] were obtained from AnalyRugby software for each individual player. Regression equations to predict [CK] from game statistics were created using a backwards random-effects maximum likelihood regression.Results: The [CK] (mean (SD)) from pre-game to post-game was 926.8 (204.2) IU. Game time and time defending were significantly correlated to [CK] in both the forwards and backs. The predicted [CK] (mean (95% confidence limit)) was 1439.8 (204.9) IU for the forwards and 545.3 (78.0) IU for the backs and was significantly correlated with the actual [CK] (r = 0.69 and r = 0.74).Conclusions: CK increased from pre-game to post-game in a position-specific manner. A large proportion of the [CK] can be explained by physical impact and thus can be predicted using a prescribed number of game statistics. As the [CK] is an indicator of muscle damage, the prediction of [CK] provides a theoretical basis for recovery strategies and adjustment of subsequent training sessions after rugby union games.

  • Individual perception of recovery is related to subsequent sprint performance
  • 2013
  • Ingår i: British Journal of Sports Medicine. - : BMJ. - 0306-3674 .- 1473-0480. ; 47:11, s. 705-709

    • Background Training recovery is vital for adaptation and performance, and to avoid cumulative fatigue and symptoms associated with overtraining. The use of cold-water immersion (CWI) as a recovery strategy is common; however, the physiological and biochemical rationale behind its use remains unclear. This study aimed to assess the relationship between body temperature responses to water immersion and individual perception of recovery, with subsequent exercise performance. Methods Twelve male rugby players participated in a 3-week cross-over trial where an intense 60 min conditioning session was followed immediately by 15 min of either 14 degrees C CWI, 30 degrees C warm-water immersion (WWI) or passive control (CON) recovery intervention. Postexercise body temperatures and subjective ratings of the recovery intervention were recorded and subsequently related to performance in a 5x40 m repeated sprint protocol undertaken 24 h later. Results CWI induced large reductions in core body temperature postimmersion (effect size (ES) range 1.05-3.21) and improved subsequent sprint performance compared to WWI (ES 1.04 +/- 0.84) and CON (ES 1.44 +/- 0.84). Both the degree of temperature decrease at 60 min postimmersion (r=0.6948; p=0.0121) and the subjective rating of the recovery intervention (r=0.5886; p=0.0441) were related to subsequent sprint performance. A very strong linear correlation was observed when these two factors were integrated (r=0.7743; p=0.0031). Conclusion A combination of physiological and psychological indices provides an improved indication of subsequent performance and suggests an important role of individual perception in enhancing training recovery.
