Recovery From 50 Eccentric Biceps Curls in Young, Untrained Men and Women

Summary

The purpose of the study is to investigate muscle stiffness in relation to muscle damaging work and to investigate how well the change in muscle stiffness correlates with the degree of muscle damage (myofibrillar disruption and necrosis). To date, the reduction in force-generating capacity is the best non-invasive marker of muscle damage. It is already established that muscle stiffness correlates well with the decline in force-generating capacity after damaging exercise. However, the correlation between degree of muscle damage and muscle stiffness has not yet been investigated. The main focus of the study is therefore to investigate the relationship between muscle stiffness and muscle damage. Further, the researchers aim to investigate how calcium cycling is affected by damaging work, and if impaired calcium cycling may partially explain the observed reduction in force-generating capacity.
