Variability of ventilation during exercise is greater in adolescents than in adults Adolescence involves rapid physiological changes that may affect ventilatory control. This study used Poincaré and approximate entropy (ApEn) analyses to assess ventilatory variability and…

Study of #ventilatory #variability during steady-state #exercise in healthy adolescents and young adults finds greater ventilatory variability and randomness in adolescents, likely reflecting immature ventilatory control

Breathing technique‐dependent acute cardiopulmonary responses during squats in healthy females Breath-holding (BH), including variations of the Valsalva maneuver, is used during resistance exercise to stabilize the trunk and increase intra-abdominal pressure. However, its hemodynamic and…

#WomensHealth #Research: #Hemodynamic and #ventilatory effects of breath-holding are investigated during low-to-moderate intensity #strength #training in healthy women, and show dependence on the #breathing technique used.
