“…However, in the present study, differences between the displacement forms were observed for all cadences, including 80 bpm. This difference between studies may be due to the higher sample size in the present study (12 subjects) compared to the results of Kanitz et al 3 who recruited only six subjects.…”

“…However, Kanitz et al 3 did not find a significant difference between deep water running with and without displacement in cardiorespiratory responses at a cadence of 80 bpm. The authors believe that, despite the increased resistance to exercise with horizontal displacement, the lower displacement velocity may have contributed to submaximal resistance, which influences the variables.…”

“…In deep water running, resistance can be increased by using different arm movements 22 and alternating running with and without displacement. 3 In this way, Kanitz et al 3 compared deep water running with and without displacement in a submaximal cadence of 80 bpm. The authors observed no significant differences in VO 2 , energy expenditure (EE) or perceived exertion (PE) and stated that the low linear velocity of horizontal displacement at a submaximal cadence (80 bpm) may have contributed to the resistance, which was maximized to influence other variables.…”

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.
