It has been suggested that deep squats could cause an increased injury risk of the lumbar spine and the knee joints. Avoiding deep flexion has been recommended to minimize the magnitude of knee-joint forces. Unfortunately this suggestion has not taken the influence of the wrapping effect, functional adaptations and soft tissue contact between the back of thigh and calf into account. The aim of ...

The purpose of this investigation was to examine the effect of an 8-week training program with heavy- vs. light-load jump squats on various physical performance measures and electromyography (EMG). Twenty-six athletic men with varying levels of resistance training experience performed sessions of jump squats with either 30% (JS30, n = 9) or 80% (JS80, n = 10) of their one repetition maximum in ...

Background: Wearable technology is used by clinicians and researchers play a critical role in biomechanical assessments rehabilitation. Objective: The purpose of this research to validate soft robotic stretch (SRS) sensor embedded compression knee brace (smart brace) against motion capture system focusing on joint kinematics. Methods: Sixteen participants donned the smart completed three separa...
