Key result
Physiological reductions in perfusion pressure (hand above heart level) increased muscle fatigue in 5 of 7 subjects, accompanied by a proportional rise in central blood pressure.
Why the study?
Does reduced arterial perfusion pressure increase fatigue in a working human hand muscle?
Does reduced arterial perfusion pressure increase fatigue in a working human hand muscle?
Physiological reductions in perfusion pressure can increase human muscle fatigue, which is accompanied by a proportional compensatory rise in central blood pressure.
No takes yet. Share an insight, caveat, or question.
Reduced perfusion may accelerate hand muscle fatigue; hypothesis-generating for compensatory BP responses in larger cohorts.
Wright et al. (1999) studied Healthy (n=7). Hand above heart level vs. Hand at heart level was evaluated on Muscle fatigue assessed by maximal isometric twitch. Physiological reductions in perfusion pressure (hand above heart level) increased muscle fatigue in 5 of 7 subjects, accompanied by a proportional rise in central blood pressure.
