Developmental phase

Primary outcomes

Vertical jump reach and initial 0.3 seconds of upward velocity.Vertical reach was measured using a Vertec as participants jumped upwards from a squat jump position. The maximum height of the plastic vains that they displaced was recorded. For the 0.3 sec vertical acceleration silver surface reflective markers were placed on participant's anterior superior iliac spine bilaterally. Infrared cameras were used to measure how quickly the reflective markers accelerated upwards. The centroid of the two reflective markers was mathematically determined and used to calculate vertical velocity.

Interventions/Control_1

Participants were randomly assigned to 3 interventional groups between testing sessions: 1) lower body strength training, 2) lower body proprioceptive training, and 3) a no training control. Group 1 underwent supervised exercises 3 days a week at 2 sets of 12 repetitions of squats, seated knee extensions, standing knee flexions, and standing calf raises at approximately 25% of their body weight.

Interventions/Control_2

Group 2 participants engaged in 4 supervised proprioceptive exercise stations 3 days a week involving Bosu ball stance, Rocker board, Body blade, and one-legged stance exercises at 4 min per station

Interventions/Control_3

Group 3 was a control and they just underwent baseline and post-testing.

Results

Results: Analysis of group*time demonstrated a small positive improvement in overall group performance for jump height at post-test F(2,36) = 5.527, p = 0.008, r = 0.36. However, post-hoc testing demonstrated no statistically significant difference between groups for study dependent variables.
Conclusions: One week of lower body weight training or lower body proprioceptive training was insufficient to induce a statistically significant improvement in vertical jump performance.
