Role of Skeletal Muscle Nitric Oxide Production in Age-related Fatigue and Fatigability
This is a pilot study funded by the National Institutes of Health. In this project, we will investigate the potential effect of skeletal muscle nitric oxide (NO) production on muscle strength and physical function in older…

Aging
Fatigability of Lower Limb Muscle in Older Adults: Protective Effects of Strength Training Exercise in Old Men and Women
The proposed studies will assess 1) the mechanisms for the age-related increase in fatigability during dynamic exercise (Aims 1 and 2) and 2) the effectiveness of high-velocity resistance training coupled with blood flow…

4 mA tDCS, Estrogen, and Leg Muscle Fatigability
The majority of transcranial direct current stimulation (tDCS) studies have failed to consider sex as a modulating factor. This neglect may partly account for the high inter-subject variability bemoaned by many tDCS investigators…
