To profile the seasonal changes of maximal swimming power (PP) in collegiate swimmers.

This 21-week study examined the changes in maximal swimming power of 16 collegiate swimmers before, throughout, and after a double taper season. Following a standard warm-up, the swimmers were tethered to a computerized force transducer. The swimmers swam two maximal swim trials with the peak force values recorded for each trial. The swimmers were tested five times throughout the season just prior to the corresponding competition dates.

PP fluctuated throughout the season. An unexpected 9% (±4.57) mean decrease in PP corresponding with the first taper (p < .05) was followed by a 21%(±4.81) increase in PP over the last half of the season (p < .01). PP was significantly correlated with swimming velocity at 50, 100, and 200y distances throughout the entire season with higher correlations earlier in the season (p < 0.05 to .001).

PP is trainable and fluctuates during the season. There is a very strong relationship between increases in PP and swimming velocity throughout the entire season. There is a possible negative relationship between time off weight training and PP. Supported by Frost Research Center, Hope College, Holland, MI 49423
