The prediction of power and efficiency during near-maximal rowing.

摘要: The relationship between power and gross efficiency during near-maximal rowing, physiological measures of strength, power, aerobic anaerobic capacities United State Rowing Association (USRA) performance tests (independent variables) was investigated among collegiate male rowers. Criterion rowing were measured in a moving-water tank, using an oar instrumented with strain gauges to assess force potentiometer position. Bivariate correlation analysis (n = 28) indicated no the independent variables (P > 0.05). [mean (SD) 483.4 (34.75) W] significantly related inboard leg extension strength (IL r 0.63), outboard (r 0.45), combined time complete USRA 2000-m simulated race −0.52; P < Stepwise regression resampling cross-validation 15 random samples (21 subjects per sample selected from total group 28 intercollegiate oarsmen) that predictors IL blood lactate following peak oxygen uptake test significant multiple correlations R 0.61 0.86 standard error estimate (SEM) ranged 18.1 29.9 W, or 5.3 (0.77)% criterion value.

In conclusion, data present study suggest increase training should emphasize decrease level accumulated rowing.
