Responses to exercise at a given percentage of one's maximum rate of oxygen consumption
(V̇o2max), or percentage of the power associated with V̇o2max during a graded exercise …

The mechanical unloading of spaceflight elicits a host of physiological adaptations including
reductions in muscle mass, muscle strength, and muscle function and alterations in central …

Exercise intolerance is a primary symptom of heart failure (HF); however, the specific
contribution of central and peripheral factors to this intolerance is not well described. The …

We have previously predicted that the decrease in maximal oxygen uptake (V̇o2max) that
accompanies time in microgravity reflects decrements in both convective and diffusive O2 …

Purpose: Training characteristics such as duration, frequency, and intensity can be
manipulated to optimize endurance performance, with an enduring interest in the role of …

Background Exercise countermeasures are the main approach taken to protect astronauts
from musculoskeletal deconditioning in microgravity (μg). Future exploration class missions …

INTRODUCTION: This study aimed to determine values and ranges for key aerobic fitness
variables that can individually map the level of success for planetary mission tasks …

Objective Exercise-induced muscle damage (EIMD) has been shown to reduce endurance
exercise performance. This study examined the effects of EIMD on critical torque (CT) and …

With the completion of the Chinese space station, an increasing number of extravehicular
activities will be executed by astronauts, which is regarded as one of the most dangerous …
