BACKGROUND Healthy young women who engage in an exercise program may lose fat that is not reflected in body weight changes because of concurrent gains in fat-free mass (FFM). OBJECTIVE This study addressed the question of how well anthropometry-based predictive equations can resolve these changes. DESIGN Several widely used skinfold-thickness- or(More)
Through its association with fat-free mass (FFM), bioelectrical impedance analysis (BIA) offers an alternative to physical performance testing. We examined the relations between stature2/resistance (S2/R), FFM, and muscular strength in data from three studies of young military men and women. Resistance was measured at 50 kHz by using the conventional(More)
The purpose of this study was to investigate the effects of aging on the cutaneous circulatory response to heat stress. Young (6–8 too) and old (22–24 mo) Fischer 344 rats were placed unanesthetized in an environmental chamber arranged so that the body could be heated while the tail remained at ambient temperature (23°C Total blood flow (TBF) to the tail(More)
STUDY DESIGN Cross-sectional study. OBJECTIVES The purpose of this study was to examine the effects of the superficial heating modality, Fluidotherapy, on skin temperature and on sensory nerve action potential (SNAP) conduction latency and amplitude of the superficial radial nerve in healthy individuals. BACKGROUND Fluidotherapy is a dry, superficial(More)
Although tape measurement of thigh girth is a common component of a clinical knee examination, the implications of thigh girth asymmetry are not well understood. The purpose of this study was to examine the relationship between thigh girth asymmetry and torque asymmetry for extension and flexion of the knee. Thirty subjects with thigh girth asymmetry of at(More)
This study assessed whether a practice effect occurs across five serial administrations of the sensory organization test. Composite equilibrium scores and mean equilibrium scores from 30 healthy volunteers (M age=36.9, SD = 12.2 yr.) performing each of the six test conditions were examined using a two-way repeated-measures analysis of variance. Analysis(More)
The aims of this study were: (1) to determine the macro- and microvascular actions of nitrous oxide (N2O) in the rat, and (2) to determine whether the vascular actions of N2O involved specific interaction with alpha-adrenergic receptors or opioid receptors. Systolic blood pressure, heart rat, total tail blood flow, blood cell velocity in subepidermal(More)
