Association between dietary fat intake, liver fat, and insulin sensitivity in sedentary, abdominally obese, older men.
Whether dietary fat influences the interaction between liver fat, visceral adipose tissue (VAT), and metabolic risk is unclear. Thus, we sought to determine the independent associations between 1 and 10 d dietary fat intake, liver fat, and […]

Muscle deoxygenation of upper-limb muscles during progressive arm-cranking exercise.
The purpose of this study was to determine which upper-limb muscle exhibits the greatest change in muscle deoxygenation during arm-cranking exercise (ACE). We hypothesized that the biceps brachii (BB) would show the greatest change in muscle deoxygenation during progressive ACE to exhaustion relative to […]

The potential benefits of creatine and conjugated linoleic acid as adjuncts to resistance training in older adults.
Human aging is associated with a significant reduction in muscle mass (sarcopenia) resulting in muscle weakness and functional limitations in the elderly. Sarcopenia has been associated with mitochondrial dysfunction and the accumulation of mtDNA deletions. Resistance […]
Resistance training, sarcopenia, and the mitochondrial theory of aging.
Skeletal muscle aging is associated with a significant loss of muscle mass, strength, function, and quality of life. In addition, the healthcare cost of aging and age-related disease is growing, and will continue to grow as a larger proportion of our population reaches retirement […]
Effect of estrogenic compounds (estrogen or phytoestrogens) combined with exercise on bone and muscle mass in older individuals.
Exercise has a beneficial effect on bone, possibly by stimulating estrogen receptor α. Because estrogen up-regulates this receptor, estrogen therapy combined with exercise training may be optimal for increasing bone mineral density. Studies combining estrogen […]
Timing of creatine or protein supplementation and resistance training in the elderly.
Muscle loss with age has a negative effect on strength and functional independence. Age-related loss of muscle is the result of decreased muscle fiber number and size, which are functions of altered hormonal status, physical inactivity, and variations in nutritional intake. […]
Vascular nitric oxide: effects of exercise training in animals.
Exercise training is known to induce several adaptations in the cardiovascular system, one of which is increased skeletal muscle blood flow at maximal exercise. Improved muscle blood flow, in turn, could in part be accounted for by augmented endothelium-dependent, nitric oxide (NO)-mediated vasodilation. Studies […]
The impact of nutritional and exercise strategies for aging bone and muscle.
This symposium addressed recent evidence suggesting that nutritional intervention and resistance-training strategies may be important for aging bone and muscle. The physiological consequences of aging and the potential mechanistic actions of nutritional aids during resistance training were emphasized.
