Effects of exercise timing on sleep architecture and nocturnal blood pressure in prehypertensives.

Background: During nocturnal sleep, blood pressure (BP) "dips" compared to diurnal BP, reducing stress on the cardiovascular system. Both the hypotensive response elicited by acute aerobic exercise and sleep quality can impact this dipping response.

Purpose: The purpose of this study was to investigate the effects of aerobic exercise timing on circadian BP changes and sleep architecture.

A comparison of men's and women's strength to body mass ratio and varus/valgus knee angle during jump landings.

The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.

Effects of lactate consumption on blood bicarbonate levels and performance during high-intensity exercise.

The authors sought to determine the effects of oral lactate consumption on blood bicarbonate (HCO(3)-) levels, pH levels, and performance during high-intensity exercise on a cycle ergometer. Subjects (N = 11) were trained male and female cyclists. Time to exhaustion (TTE) and total work were measured during high-intensity exercise bouts 80 min after the consumption of 120 mg/kg body mass of lactate (L), an equal volume of placebo (PL), or no treatment (NT).

Effect of leucine supplementation on indices of muscle damage following drop jumps and resistance exercise.

The purpose of this study was to determine the effect of leucine supplementation on indices of muscle damage following eccentric-based resistance exercise. In vitro, the amino acid leucine has been shown to reduce proteolysis and stimulate protein synthesis. Twenty-seven untrained males (height 178.
