The effects of whole-body vibration amplitude on glucose metabolism, inflammation, and skeletal muscle oxygenation.

Whole-body vibration (WBV) is an exercise mimetic that elicits beneficial metabolic effects. This study aims to investigate the effects of WBV amplitude on metabolic, inflammatory, and muscle oxygenation responses. Forty women and men were assigned to a high (HI; n = 20, Age: 31 ± 6 y) or a low-amplitude group (LO; n = 20, Age: 33 ± 6 y).

Exercise testing in patients with cystic fibrosis-importance of ventilatory parameters.

Background: Ventilatory parameters obtained during exercise predict survival in several chronic diseases; however, long-term changes in exercise ventilatory parameters in patients with cystic fibrosis (CF) have yet to be examined and potential differences between sexes in CF are unknown.

Purpose: We sought to examine the change in exercise ventilatory parameters over time in patients with CF and determine if the change is different between sexes.

Methods: Exercise capacity (VO peak) and exercise ventilatory parameters (V/VO peak, V/VCO peak, and V/VCO slope) were determined from a maximal cardio-pulmonary test on a cycle ergometer on two visits separated by 39 ± 16 months in 20 patients with CF (10 female, 10 male).
