The effects of supplementation of the leucine metabolite beta-hydroxy-beta-methylbutyrate (HMB) were examined in a resistance training study. Thirty-nine men and 36 women between the ages of 20-40 y were randomized to either a placebo (P) supplemented or HMB supplemented (3.0 g HMB/d) group in two gender cohorts. All subjects trained three times per week(More)
Osteopenia/osteoporosis, sarcopenia, and obesity are commonly observed in the process of aging, and recent evidence suggests a potential interconnection of these syndromes with common pathophysiology. The term osteosarcopenic obesity has been coined to describe the concurrent appearance of obesity in individuals with low bone and muscle mass. Although our(More)
BACKGROUND Combining the amino acids arginine and glutamine with the leucine metabolite beta-hydroxy-beta-methylbutyrate (HMB) has been shown to reverse lean tissue loss in cancer and acquired immunodeficiency syndrome (AIDS) patients. Although each of these nutrients has been shown to be safe, the safety of this mixture has not been reported. Three(More)
Our study aims were: 1) to determine whether assisted weight bearing or additional weight bearing is more beneficial to the improvement of function and increased stability in gait and dynamic balance in patients with Parkinsonism, compared with matched controls (treadmill alone). Twenty-three men and women participants (M +/- SD = 74.5 +/- 9.7 yrs; Males =(More)
BACKGROUND While chronic β-Hydroxy β-Methylbutyrate (HMB) supplementation (≥ 2 wk) lowers exercise induced muscle damage, its acute or timing effects have not been examined. The purpose of this study was to investigate the acute and timing effects of oral HMB supplementation on serum creatine kinase (CK), lactate dehydrogenase (LDH), muscle soreness, and(More)
The purpose of this review was to examine the relationship between physical performance and body composition measurements, including fat/muscle mass and bone mineral density (BMD) in individuals ≥60 years of age. Various measurements used to assess body composition, BMD, and physical performance (PP) were discussed as well. Medline/PubMed, CINAHL, and SCIE(More)
The purpose of the study was to determine the accuracy of 11 prediction equations in estimating the 1 repetition maximum (1 RM) bench press from repetitions completed by collegiate football players (N = 69) using 225 lb. The demographic variables race, age, height, weight, fat-free weight, and percent body fat were measured to determine whether these(More)
OBJECTIVE To determine whether women with fibromyalgia benefit from strength training. DESIGN Randomized controlled trial. SETTING Testing was completed at the university and training was completed at a local community wellness facility. PARTICIPANTS Twenty-nine women (age range, 18-54 y) with fibromyalgia participated. Subjects were randomly assigned(More)
The leucine metabolite, beta-hydroxy-beta-methylbutyrate (HMB) enhances the effects of exercise on muscle size and strength. Although several reports in animals and humans indicate that HMB is safe, quantitative safety data in humans have not been reported definitively. The objective of this work was to summarize safety data collected in nine studies in(More)
There is increasing interest in how the quality of community environments influences health. We present the results of a pilot study designed to encourage overweight and obese low-income women to increase their level of physical activity, and explore the factors that either support or constrain their walking. The findings suggest that even relatively small(More)
