BACKGROUND Obesity rates have reached epidemic proportions in the United States and California. Thus, the California Department of Education began a series of steps to address the increase in obesity and decline in fitness in the 6.3 million public school children in California. We evaluated serial changes in obesity and fitness in California school children following implementation of preventi...

BACKGROUND Muscle strength is necessary for upper body normal function. Upper extremity function impairments have been reported in breast cancer (BC) survivors. It is not possible to know precisely if cancer adjuvant therapy such as radiation and chemotherapy had any effect on the unaffected arm. The aim of this study was to compare shoulder girdle strength among women with BC and similarly age...

The purpose of this study was to evaluate the effects of 2 modes of aerobic exercise (continuous or intermittent) on maximum strength (1 repetition maximum, 1RM) and strength endurance (maximum repetitions at 80% of 1RM) for lower- and upper-body exercises to test the acute hypothesis in concurrent training (CT) interference. Eight physically active men (age: 26.9 +/- 4.2 years; body mass: 82.1...

PURPOSE Current evidence suggests many health benefits from physical activity during and after cancer treatment. However, the optimal exercise program for cancer survivors has not yet been established. The purpose of this meta-analysis was to summarize evidence for the efficacy of resistance training (RT) interventions to improve muscle strength and body composition among adult cancer survivors...

It is unclear whether gender differences in the relative strength of the upper and lower body are due to differences in muscle mass distribution or dissimilarity of use. There is also controversy as to whether prolonged resistance training increases strength per unit cross-sectional area (CSA). To help resolve these questions, maximum isometric torque per unit muscle and bone (M+B) CSA was meas...

Twelve middle-aged women (mean age 41.9 +/- 1.6 y) performed variable-cam resistance training and aerobic training 3 times/week for 14 weeks. One repetition maximum (1 RM) significantly increased between pre-training and training week 7 (13.1%-17.8%), between training week 7 and post-training (10.8%-14.1%), and between pre-training and post-training (25.5%-30.9%). Total-body lean soft tissue an...
