PURPOSE To determine if there is an optimal grip span for determining the maximum handgrip strength in male and female teenagers, and if the optimal grip span was related to hand span. If they are related then the second aim was to derive a mathematic equation relating hand span and optimal grip span. METHODS One hundred healthy teenage boys (15.1 +/- 1.1 y) and 106 girls (15.4 +/- 1.3 y) wer...

INTRODUCTION The hand grip strength test provides useful and reliable information about overall health. Different studies have investigated the optimal grip span for determining maximal hand grip strength in different populations such as adults, adolescents and children without disabilities. OBJECTIVE To ascertain whether there is an optimal grip span for determining maximal hand grip strengt...

This study investigates which position (grip span) on the standard grip dynamometer results in maximum grip strength. Our null hypotheses included (1) no optimal grip span exists for measuring grip strength and (2) optimal grip span is unrelated to hand size. We also intended to derive a simple mathematical algorithm to adapt grip span to hand size. Seventy healthy subjects (40 women/30 men; me...

The perceptual span and eye–hand span of pianists were examined while they played and read single-line melodies (with four beats per measure). The perceptual span was measured by the use of a moving-window technique with four window conditions: two beats, four beats, six beats, or no window. It was found that pianists need to see no more than the whole measure that they are fixating in order to...
