Abstract

KANITZ, A.C. et al. Cardiorespiratory responses during deep water running with and without horizontal displacement at different cadences. Rev Andal Med Deporte [online]. 2014, vol.7, n.4, pp.149-154. ISSN 2172-5063.  https://dx.doi.org/10.1016/j.ramd.2014.07.002.

Objective: To compare the cardiorespiratory responses during deep water running with and without displacement at different cadences. Methods: Twelve young women performed deep water running with and without displacement during 4 min at three separate cadences: (a) 60 bpm; (b) 80 bpm; and (c) 100 bpm. The heart rate (HR), ventilation (Ve) and oxygen uptake (VO₂) were collected in the last minute of each test. Two-way ANOVA for repeated measures was used with Bonferroni's post hoc test (p < 0.05) to compare variables. Results: The results showed a significant increase in all variables as the cadence increased (HR: p < 0.001; Ve: p < 0.001; VO₂: p < 0.001). In addition, the VO₂ and Ve values were significantly higher for deep water running with displacement compared to running without displacement (VO₂: p = 0.047; Ve: p = 0.007). However, there was no significant difference in HR with and without displacement (p = 0.065). Conclusions: The results indicate that the increase in both cadence and displacement results in significant cardiorespiratory responses as a result of deep water running. This finding is important for adapting exercise prescription to the goals of participants.
