Hand dynamometer: effects of trials and sessions.
12 normal, self-reported dextral subjects (6 men, 6 women) were assessed with a hand dynamometer with 10 trials per hand for 10 consecutive wk. The test-retest reliability of the 10-trial average across the 10 sessions averaged .91 for men and .94 for women for both preferred and nonpreferred hands. Fatigue effects over trials were statistically significant for both sexes and hands except for women's preferred hand. Skill acquisition effects over sessions were only statistically significant for men's nonpreferred and women's preferred hands.
