Plyometrics Improve Swimming Performance Compared to Nothing
In 2011, Potdevin took 33 adolescent swimmers (M=10, F=13) who swam 5.5 hours/week and split them split into a control (C) or plyometric group (PG) for six weeks. The PG performed two training sessions/week and a total of 2,146 jumps were performed. The PG was systematic and progressive using a variety of double and single limb jumps. Swimming and land performance tests were performed before and after the six weeks. The PG had significant increases in the countermovement jump (CMJ) and squat jump (SJ). The PG had significant improvements in maximal glide speed. Swimming velocity during a 400- and 50-meter swim significantly increased in the PG.
