MORAES, H.B. et al. Heart rate, rating of perceived exertion and blood lactate levels in jump fit and hydro jump classes. Motri. [online]. 2012, vol.8, n.2, pp.52-61. ISSN 1646-107X.  https://doi.org/10.6063/motricidade.8(2).712.

The purpose of the present study was to compare the heart rate responses (HR), rating of perceived exertion (RPE) and blood lactate levels in jump fit and hydro jump classes. The sample comprised 8 female subjects (43.5 ± 5.2 years, 160.0 ± 4.68 cm, 58.93 ± 4.15 kg and 25.69 ± 4.40 %BF), all of them participants of jump fit classes. The study involved three evaluation moments. The first moment consisted of evaluating anthropometric measurements, resting heart rate and resting blood lactate levels, familiarization and training of hydro jump class and how to use the rating of perceived exertion scale (RPE). The second and third moments included collecting the variables during hydro jump class. 48 hours later, the variables during jump fit class were collected. Descriptive and inferential analysis consisted in applying one way ANOVA and Tukey’s Post Hoc test in order to compare the HR and lactate blood levels during exercise, and further the Wilcoxon test to compare the RPE. A statistical significance was assumed as p < .05. No statistically relevant differences were found among the average values of all the variables studied. Jump classes had similar effects on the variables both in the terrestrial and aquatic context.

Keywords : rebound exercise; heart rate; rate of perceived exercitation (RPE) and blood lactate.
