Abstract

The purpose of this study was to compare dynamic stability on land and in water, between young and middle-aged adults performing plyometric exercises. Twenty adults were asked to volunteer: Young = 24.40 ± 2.63 years, n = 10 and middle-aged = 46.80 ± 3.05 years, n = 10. Participants performed three plyometric exercises (countermovement jump, squat jump, and drop landing) on land and in waist-deep water. Dynamic stability was assessed during landing for each exercise using a time to stabilization (TTS) paradigm. Data were collected via a waterproof force plate positioned on an adjustable-depth pool floor and analyzed with a 2 (age) X 2 (environment) x 3 (jump type) repeated measures ANOVA. Results revealed TTS was greater on land (1.45 ± 0.12s) than in water (1.35 ± 0.12s) for two jumps (p = 0.01). Across both age groups, dynamic stability was better in the water. This suggests that jump training in water may be beneficial for improving dynamic stability.
