Research in instability has focused on the analysis of muscle activation. The aim of this
systematic review was to analyse the effects of unstable devices on speed, strength and …

The aim of this study was to determine whether whole body vibration increases movement
variability while performing a half squat with different ballasts and rhythms through entropy …

The effect of electromyographic (EMG) activity on agonist muscles during exercises
performed on stable and unstable surfaces remains uncertain. We aimed to review the …

Objective: The purpose of this study was to compare the impact of unilateral (U) and bilateral

Introduction Core stability is crucial for preventing and rehabilitating lumbar spine injuries.
An external focus instruction using a paper balloon is an effective way to activate the trunk …

Context: The quadriceps femoris is consistently ranked among the muscles most prone to
sustain strain injuries in sports involving kicking and sprinting actions. Given the …

(I) Training in unstable conditions, with different elements, platforms, or situations, has been
used because there is a significant increase in muscle activation, balance, proprioception …

Purpose We previously reported that a Hammerobics exercise using weights can enhance
trunk and lower extremity muscles, some studies suggested that training effects could also …

Training using instability devices is common; however, for highly trained athletes, a single
device may not provide sufficient challenge. This study examines the effect of superimposed …

[Purpose] This study aimed to develop a more effective exercise program for lower extremity
muscle function by evaluating the effects of an 8-week lunge exercise performed on an …
