Calcium β-hydroxy β-methylbutyrate (HMB) supplementation has been reported to reduce catabolism and promote gains in strength and fat free mass in untrained individuals initiating training. However, the effects of HMB supplementation on strength and body composition alterations during training in athletes is less clear. This study examined the effects of 28-d of calcium HMB supplementation during intense training on markers of catabolism, body composition, strength, and sprint performance. In a double-blind and randomized manner, 28 NCAA division I-A football players were matched-paired and assigned to supplement their diet for 28-d during winter resistance/agility training (~8 hr/wk) with a carbohydrate placebo …


Moderate Intensity Exercise Training Improves Cardiorespiratory Fitness In Women, J. David Branch, Russell R. Pate, Sharon P. Bourque Jan 2000

Moderate Intensity Exercise Training Improves Cardiorespiratory Fitness In Women, J. David Branch, Russell R. Pate, Sharon P. Bourque

Faculty Publications

Among women, there is an increased prevalence of sedentary lifestyle and less participation in physical activity at levels recommended by the Surgeon General. As a result, women have been identified as a target group in public health initiatives to increase physical activity. The health-related benefits of habitual, moderate intensity physical activity are well documented in the epidemiological literature, but less is known about the effect of such physical activity on cardiorespiratory fitness. Our hypothesis was that moderate and vigorous exercise training regimens of similar estimated energy expenditure would result in similar changes in cardiorespiratory fitness. Eighteen sedentary premenopausal women with …

The Effects Of Exercise And Smoking On Serumlecithin: Cholesterol Acyltransferase Activity Inyoung Men, Cumhur Kilinç, Zübeyr Yağmur, Kurtuluş Yilmaz, Üçler Kisa

Turkish Journal of Medical Sciences

Lecithin: cholesterol acyltransferase (LCAT) is an enzyme responsible for the formation of most cholesteryl esters (CE) in human serum. In this study investigating the effects of exercise and smoking on LCAT acitvity, serum triglyceride (Tg), total cholesterol (C), HDL-C, HDL3-C and LCAT activity were measured in the sera of 29 nonsmoking and 36 smoking (at least one packet/day) young men before and after their 6-week military training period. LCAT activity was determined by measuring the amount of cholesterol esters produced in the incubation of serum and reconstituted HDL including [ 14 C]-cholesterol. Tg and C were measured with enzymatic-colorimetric methods. …


The Relationship Between Functional And Histological Changes In Muscle Following Eccentric Exercise In Mice, Michael John Newton Jan 2000

The Relationship Between Functional And Histological Changes In Muscle Following Eccentric Exercise In Mice, Michael John Newton

Theses: Doctorates and Masters

Exercise-induced muscle damage (EIMD) is known to be produced by novel or unaccustomed exercise, especially high force eccentric contractions. Histological myofibre disruption, force loss and muscle soreness are associated with EIMD and have implications for sporting performance. Traditional practices of assessing the extent of disruption to the myofibres is by performing needle biopsies and subsequently analysing the histology of the fibres. Recently there has been interest in investigating whether changes in force production and contractile properties of muscle following damaging exercise correlate strongly with the magnitude of disruption to the myofibres. The main aim of this study was to investigate …
