ranges from a few weeks to several months, one can easily imagine that an injury seriously affects a player’s aerobic fitness. 9 Fortunately, the negative effects of detraining on aerobic performance can be reversed by endurance training. 10 To accomplish this, training loads during the rehabilitation

screened neuromuscular ACL injury risk factors change significantly from preseason to midseason in women’s collegiate soccer athletes. A recently identified and rapidly emerging category of risk factor for many lower-extremity injuries is training load. 33 Training load can be defined as stress placed on

Therefore, the field evaluation and monitoring of these hormones (TT and C), together with the training load, can elucidate, with greater accuracy, the adaptive responses

Considerations for Single and Double Leg Drop Jumps: Bilateral Deficit, Standardizing Drop Height, and Equalizing Training Load
Matthew T.G. Pain
Bilateral deficit is well documented; however, bilateral deficit is not present in all tasks and is more likely in dynamic activities than isometric activities. No definitive mechanism(s) for bilateral deficit is known but an oft cited mechanism is lower activation of fast twitch motor units. The aim of this study was to produce comparable and consistent one and two legged drop jumps to examine bilateral deficit in elite power athletes and elite endurance athletes. Seven power athletes and seven endurance athletes performed single and double leg drop jumps from a range of heights that equalized loading per leg in terms of: height dropped, energy absorbed, and momentum absorbed. Force and motion data were collected at 800 Hz. Bilateral deficit for jump height, peak concentric force, and peak concentric power were calculated. Power athletes had a significantly greater (P < .05) bilateral deficit for jump height and peak power, possibly due to power athletes having more fast twitch motor units, however, endurance athletes generally had a bilateral surfeit which could confound this inference. Results indicate that equalizing loading by impulse per leg is the most appropriate and that a consistent drop height can be obtained with a short 10 minute coaching session.
