Hypohydration Reduces Vertical Ground Reaction Impulse But Not Jump Height

摘要

This study examined vertical jump performance using a force platform and weighted vest to determine why hypohydration (approximately 4% body mass) does not improve jump height. Jump height and other measures of functional performance from a force platform were determined for 15 healthy and active males when euhydrated (EUH), hypohydrated (HYP) and hypohydrated while wearing a weighted vest (HYPv) adjusted to precisely match water mass losses. HYP produced a significant loss of body mass - 3.2 +/- 0.5 kg (- 3.8 +/- 0.6%); P.
