There is currently a dearth of scientific literature exploring the agreement of A-mode ultrasound (US) body composition analysis with dual-energy X-ray absorptiometry (DXA) and air displacement plethysmography (ADP).
To investigate the agreement of US with DXA and ADP for estimating fat mass (FM) and fat-free mass (FFM).
College-age men (n = 33) and women (n = 41) volunteered to participate in this study.

Obesity is a steadily growing epidemic affecting all segments of the population including college-aged students. The weight gain that is evidenced amid the transitional stage of college years increases the risks associated with cardiovascular and metabolic diseases. The BodyMetrix® BX-2000 (ULTRA) using a seven-site method has been evaluated against dual-energy X-ray absorptiometry (DXA) for estimation of body composition, which has yielded conflicting results.

The BodyMetrix(®) BX-2000 Ultrasound device (ULTRA) shows prowess in being an effective alternative to the expense and technicality of dual-energy X-ray absorptiometry (DXA). However, this technique has not been investigated using a seven-site methodology.
To employ a cross-over design to investigate the agreement between ULTRA using a seven-site methodology and DXA in assessing body fat (%BF) in a normal-weight sample of college-age men and women.

Sleep deprivation and cold air exposure are both experienced in occupational and military settings but the combined effects of these 2 stressors is unknown. The purpose of this study was to determine the effects of 53 hours of total sleep deprivation on thermoregulation during the rewarming phase (25°C air) after acute cold air exposure (10°C air).
Eight young men underwent 2 trials in which they either received 7 hours of sleep at night or were totally sleep deprived.

It has been repeatedly demonstrated that increasing the variety of available food and purchasing options reliably increases eating and consumer spending behavior, respectively. However, the potential probehavioral effect of increasing the variety of exercise equipment options on the amount of exercise individuals perform is very limited. The purpose of this investigation was to compare the amount, enjoyment (liking), and effort perception of resistance training exercise vs.
