Resumo(s)
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.
