An All-Out Test to Determine Finger Flexor Critical Force in Rock Climbers

The fatigue resistance of the finger flexors is known to be a key determinant of climbing performance. This study set out to establish the association between the single all-out assessment of finger flexor critical force (ff-CF) and the impulse above CF (W') on climbing performance (self-reported sport and boulder climbing ability).A total of 129 subjects completed an assessment of dominant arm ff-CF, comprised of a series of rhythmic isometric...
