The relationship between handgrip isometric strength and swimming performance was assessed in the four competitive swimming strokes in swimmers of different age groups and of both sexes. 78 national-level Portuguese swimmers (39 males, 39 females) were selected for this study. Grip strength, previously used as a marker of overall strength to predict future swimming performance, was measured using a hand dynamometer. The best competitive time at 100 and 200 m in all four swimming strokes were converted into 2010 FINA points. Non-parametric tests were used to evaluate differences between groups. Pearson product-moment correlations were computed to verify the association between variables. Handgrip maximum isometric strength was significantly correlated with swimming performance, particularly among female swimmers. Among female age group swimmers, the relationship between handgrip and 100-m freestyle was significant. Handgrip isometric strength seems to be related to swimming performance, especially to 100-m freestyle and in female swimmers. For all other distances and strokes, technique and training probably are more influential than semi-hereditary strength markers such as grip strength.
研究人员评估了不同年龄组和性别的 78 名国家级葡萄牙游泳运动员的四种竞技游泳姿势的握力等距强度与游泳表现之间的关系。握力是一种整体力量的标志物，用于预测未来的游泳表现，此前已被用于测量。在所有四种游泳姿势中，100 米和 200 米的最佳比赛时间均转换为 2010 年国际泳联积分。研究人员使用非参数检验评估组间差异，并计算皮尔逊积矩相关来验证变量之间的关联。握力最大等距强度与游泳表现显著相关，尤其是女性游泳运动员。在女性年龄组游泳运动员中，握力与 100 米自由泳的关系具有统计学意义。握力等距强度似乎与游泳表现相关，尤其是与 100 米自由泳相关，而且在女性游泳运动员中更为显著。对于其他所有距离和泳姿，技术和训练可能比握力等半遗传性力量标志物更具影响力。
