Post-season detraining effects on physiological and performance parameters in top-level kayakers: comparison of two recovery strategies

摘要: This study analyzed changes in physiological parameters, hormonal markers and kayaking performance following 5-wk of reduced training (RT) or complete cessation (TC). Fourteen top-level male kayakers were randomly assigned to either a TC (n = 7) RT group at the end their competitive season (T1). Subjects undertook blood sampling an incremental test exhaustion on kayak ergometer T1 again 5 weeks (T2). Maximal oxygen uptake (VO2max) second ventilatory threshold (VT2) significantly decreased (-10.1% -8.8%, respectively). Significant decreases also observed but lesser extent (-4.8% -5.7% Heart rate VT2 showed significant increases (3.5%). However, no changes, detected heart VO2max any group. Peak lactate remained unchanged both groups T2. Paddling speed declined T2 (-3.3%), while paddling (-5.0% -4.2% for RT, Stroke increased only by 5.2% 4.9%, respectively. power although values higher than those TC. A decline cortisol levels (-30%) was groups, increase testosterone ratio These results indicate that strategy may be more effective order avoid excessive declines cardiovascular function paddlers. Key pointsShort-term (5-wk) athletes larger parameters when compared approach.Following athletes, strategies reflect androgenic-anabolic activity.
