[Purpose] This study investigated the effects of core muscle stability training on the weight distribution and stability of the elderly. [Subjects and Methods] Thirty elderly persons were randomly divided into an experimental group which performed core strengthening exercises, and a control group which performed standard strengthening exercises for 8 weeks. A Tetrax Interactive Balance System w...

Squat and lunge are classic exercises that have become an integral part of lower-extremity strengthening and postoperative rehabilitation programs [1]. Despite their widespread use across age and BMI spectrums, very few studies have looked at the biomechanics of these exercises. Of existing studies, most have focused on younger, normal weight, populations. The influence of obesity on the perfor...

BACKGROUND Understanding the magnitude and direction of joint forces generated by hip strengthening exercises is essential for appropriate prescription and modification of these exercises. The purpose of this study was to evaluate hip joint forces created across a range of hip flexion and extension angles during two hip strengthening exercises: prone hip extension and supine hip flexion. METH...

CONTEXT Functional exercises are often used in strengthening programs after lower extremity injury. Activation levels of the stabilizing hip muscles have not been documented. OBJECTIVE To document the progression of hip-muscle activation levels during 3 lower extremity functional exercises. DESIGN Cross-sectional. SETTING Laboratory. PARTICIPANTS 44 healthy individuals, 22 women and 22 ...

BACKGROUND Recently, physical activity (PA) was found to improve cognitive and memory functions in the brain; however, no epidemiological studies have specifically investigated this phenomenon in the Korean adolescent student population. The purpose of this study was to investigate the effects of various types of PA undertaken at various frequencies, on the academic performance of Korean adoles...

OBJECTIVE To determine whether there is sufficient evidence to conclude that exercise interventions are more effective than no exercise control and to compare the effectiveness of different exercise interventions in relieving pain and improving function in patients with lower limb osteoarthritis. DATA SOURCES Nine electronic databases searched from inception to March 2012. STUDY SELECTION R...
