Cardiorespiratory responses during deep water running with and without horizontal displacement at different cadences

Abstract

a b s t r a c tObjective: 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 (VO 2 ) 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; VO 2 : p < 0.001). In addition, the VO 2 and Ve values were significantly higher for deep water running with displacement compared to running without displacement (VO 2 : 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. Respuestas cardiorrespiratorias de la carrera en aguas profundas con y sin desplazamiento horizontal y en diferentes cadenciasPalabras clave: Ambiente acuático Mujeres jóvenes Frecuencia cardíaca Ventilación Consumo de oxígeno r e s u m e n Objetivo: comparar las respuestas cardiorrespiratorias durante la carrera en aguas profundas con y sin desplazamiento horizontal y a diferentes cadencias. Método: Doce mujeres jóvenes realizaron la carrera en aguas profundas con y sin desplazamiento durante cuatro minutos a tres cadencias diferentes: a) 60 bpm, b) 80 bpm, y c) 100 bpm. La frecuencia cardíaca (FC), la ventilación (VE) y el consumo de oxígeno (VO 2 ) se recogieron en el último minuto de cada prueba. ANOVA de dos vías para medidas repetidas con post hoc de Bonferroni (p < 0,05) se utilizaron para comparar las variables. Resultados: Los resultados mostraron un aumento significativo en todas las variables con el aumento de la cadencia (FC: p < 0,001; Ve: p < 0,001; VO 2 : p < 0,001). Además, los valores de VO 2 y Ve fueron significativamente mayores para la carrera en aguas profundas que se ejecuta con desplazamiento en comparación con la realizada sin desplazamiento (VO 2 : p = 0,047; Ve: p = 0,007). Sin embargo, no hubo diferencia significativa en FC con y sin desplazamiento (p = 0,065). Conclusiones: Los resultados indican que el incremento de la cadencia y el desplazamiento proporcionan importantes respuestas cardiorrespiratorias en la carrera en aguas profundas.

Acute Deep Water Running Response and Linear Load Inspiratory Exercise in Overweight/Obese and Slim Adults: Randomized Study

“…According to previous studies, DWR is a great therapeutic activity working on cardiovascular conditioning in young adults who are overweight, due to reduced joint overload and low risk of musculoskeletal injury. (KANITZ et al, 2014, SADEJA et al, 2019.…”

“…It is an exercise that can be performed with or without displacement, done with the individual in a vertical position with a float vest, making it impossible to touch the feet on the bottom of the pool. (KANITZ et al, 2014).…”
