Abstract

Cardiorespiratory responses during exercise have been extensively described in populations with different demographic and clinical characteristics ,while fewer studies focused on post exercise recovery. However, more recently this “window”, defined as the time between the end of a bout of exercise and the subsequent return to what is considered a “resting” state, has been considered as a discrete phenomenon that should be given attention as an independent and valuable source of information. Indeed, the analysis of recovery from exercise may provide insights that could help optimize practical applications in terms of exercise recommendations for health and performance.

Highlights

Cardiorespiratory responses during exercise have been extensively described in populations with different demographic and clinical characteristics [1,2,3,4,5], while fewer studies focused on postexercise recovery [6]
This study investigated the influence of aging and effort intensity upon oxygen uptake ( V O2 ), carbon-dioxide production ( V CO2 ), minute ventilation ( V E ) and Heart Rate (HR) during postexercise recovery
The relative contribution of B/β was similar between age groups (P > 0.05) and increased with exercise intensity (P < 0.05) for V O2 (YG vs. OG: Ex100% - 69% vs. 69%; Ex75% - 56% vs. 50%; Ex40% - 48% vs. 47%) and HR (YG vs. OG: Ex100% - 93% vs. 92%; Ex40% - 69% vs. 63%), but not V CO2 and V E

Summary

Introduction

Cardiorespiratory responses during exercise have been extensively described in populations with different demographic and clinical characteristics [1,2,3,4,5], while fewer studies focused on postexercise recovery [6]. More recently this “window”, defined as the time between the end of a bout of exercise and the subsequent return to what is considered a “resting” state, has been considered as a discrete phenomenon that should be given attention as an independent and valuable source of information. Postexercise adjustments relate with homeostatic ability and health [7].
