PINTO, Stephanie S. et al. Cardiorespiratory responses induced by hydrogymanstics exercises performed with and without the use of resistive equipment. Rev. Port. Cien. Desp. [online]. 2006, vol.6, n.3, pp.336-341. ISSN 1645-0523.

The aim of the present study was to analyse the heart rate and the oxygen uptake in hydrogymnastics exercises performed with and without the use of resistive equipment. The sample has been composed by ten young women who have undergone two sessions of aquatic tests, with the exercises jumping jack and cross country sky performed in the situations without resistive equipment, with the use of the aquafins equipment and with the use of the aqualogger equipment, which respected 30-minute breaks. For collecting heart rate and oxygen uptake data a S610 frequencimeter (POLAR) and a KB1-C gas analyser (AEROSPORT) were respectively used. ANOVA was used for repetitive measures, post-hoc Bonferroni and paired t-test (p<0.05). The cross country sky compared to the jumping jack showed a higher behavior for both variables due, probably, to a greater movement amplitude and greater muscle mass involved during the execution of the exercise. An increase statistically significant in the oxygen uptake has been observed in the cross country sky from the situation without equipment when compared with the situations with equipment. On the other hand, in the jumping jack have been noticed no differences between the situations. However, the heart rate has presented differences statistically significant among the three situations for both exercises. Therefore, the use of resistive equipment may be efficient in order to increase the cardiorespiratory responses related to the exercise done.
