Incremental effects of 28 days of beta-alanine supplementation on high-intensity cycling performance and blood lactate in masters female cyclists.

Within the aging population, there exists a subset of individuals termed masters athletes (MA). As masters-level competition increases in popularity, MA must find methods to enhance individual athletic performance. Longitudinal beta-alanine (BA) supplementation is suggested to enhance physical capability during exercise; however, these effects have not been evaluated in MA.

Effects of 28-Day Beta-Alanine Supplementation on Isokinetic Exercise Performance and Body Composition in Female Masters Athletes.

Beta-alanine (BA) supplementation increases exercise performance due to increases in the intramuscular lactate buffer, carnosine. Females are more sensitive to these increases and results are further pronounced in trained individuals. Baseline intramuscular carnosine levels also naturally decrease with age; therefore, trained older females may experience augmented benefits from BA supplementation.

Physical activity and osteoporotic fracture among older women.

Objective: To determine the importance of physical activity in the occurrence of osteoporotic fracture and to examine the impact of exercise frequency on osteoporotic fracture among a national sample of women aged 50 years and older.

Design And Setting: This study involved female participants in the Third National Health and Nutrition Examination Survey (NHANES III), Phase 1.

Subjects: The sample consisted of 2,325 women aged 50 years and older who were interviewed for Phase 1 of NHANES III.

Exercise intervention designed to improve strength and dynamic balance among community-dwelling older adults.

Loss of balance and falling are critical concerns for older adults. Physical activity can improve balance and decrease the risk of falling. The purpose of this study was to evaluate a simple, low-cost exercise program for community-dwelling older adults.
