dynamometer was placed just above the ankle, and resistance was applied downward over 1 second. Following a familiarization test, subjects performed 2 trials with standardized verbal encouragement, and the peak force (measured in kilograms) maintained for over half a second was recorded. 17 Vertical Jump Test

common athlete monitoring measures such as the hormonal response after exercise, jump tests used to assess neuromuscular fatigue or self-reports about postexercise symptoms (eg, fatigue and muscle soreness) should not be considered as measures of internal load. As a rule of thumb, an indicator of the

All the subjects had been previously familiarized with SJ and CJ tests. Blood Lactate Concentration Blood lactate concentration was measured before (pre) and

? Squash relevance? CMJ Measure of leg power The RSI and CMJ are considered to be a measure of explosive ability of the leg extensors in fast stretch–shortening cycle actions under high stretch loads. RSI (30-cm drop jump) The RSI is a ratio of jump height to ground contact time during a drop jump test

similar measures taken from force platforms during vertical jump testing. Our findings that reliability for each variable decreased at the heavier load (ie, decrease in ICC and/or increase in CV%) is also consistent with previous research on both ballistic bench press 29 and medicine ball throwing. 22

everyday living and thus the SDT is not challenging enough. Whereas the jump test could find a difference between athletes with CAI and uninjured controls. 2 To overcome this problem incorporating an additional task during the measurement could possibly reduce their ability to compensate for deficits. 8

athlete’s lower body power production ( Callister, Callister, Fleck, & Dudley, 1990 ). Moreover, the majority of the previous literature strictly reports the height achieved during jump testing (squat jump or CMJ) as evidence of lower body power production ( Filaire et al., 2001 ; Iglesias et al., 2003
