Objective: The main objective in this study was to determine possible differences in maximal strength and muscular endurance in hand grip among Tornado sailors, helmsman and crews, and non-sailors. An additional aim was to assess possible differences between the dominant and nondominant hands. Methods: Thirty-eight men, 19 of whom were sailors, were measured with a Jamar J5030 hand grip dynanometer. The maximal strength assessment protocol consisted of 3 maximum attempts with 1 minute's rest between them and muscular endurance in 1 minute of maximum isometric contraction. Results: No differences were found between helmsman and crew in any of the tests. Sailors obtained better results in the maximal strength test, 63.21 kg in the dominant hand and 59.79 kg in the nondominant hand, while non-sailors obtained 53.26 kg and 50 kg, respectively. In the endurance test, the control group showed a more marked loss of strength than the group of sailors. The dominant hand showed slightly higher strength values, which were statistically significant only in the helmsman group. Conclusions: Similar results were obtained by sailors, helmsman and crew in the maximal strength and endurance hand grip test. The results in sailors were higher than those in the control group. No differences were found between the dominant and non-dominant hands in any of the groups.
