Abstract
Athletes of different sports have frequently used warm-up exercises as preparation for the training session or competition. Increased metabolism and performance, as well as musculoskeletal injury prevention, are among the reasons that lead coaches to adopt this procedure. The effects of prior exercise have been studied to analyze the limiting factors of physiological adjustments at the beginning of exercise and its effects on subsequent exercise performance. Thus, this article analyzes studies that have investigated the effects of prior exercise on the cardiorespiratory and metabolic responses and short-term aerobic performance. In this context, factors such as prior exercise intensity and duration and recovery period between exercise sessions are discussed, and the possible mechanisms that could explain the effects of prior exercise are presented. The effects of prior exercise on the oxygen uptake (VO2) kinetics do not seem to depend on the prior exercise intensity and recovery period between exercise sessions (i.e., prior and subsequent). However, the effects on exercise tolerance appear to depend on the interaction between the intensity of both exercises and the recovery period between them.
Highlights
Warm-up has been considered important in many sports as a way of preparing athletes for competition, seeking increased metabolism and performance and as a possible way to prevent musculoskeletal injuries
Studies that have investigated the effects of prior exercises have used relatively short durations (5-15 min) and intensity varies according to the characteristics of the subsequent exercise
The heavy exercise domain is located from the lowest exercise intensity, where [La] rises (> lactate threshold (LT)) and has as its upper limit the intensity corresponding to the critical power (CP) 19
Summary
Warm-up has been considered important in many sports as a way of preparing athletes for competition, seeking increased metabolism and performance and as a possible way to prevent musculoskeletal injuries This type of intervention has attracted much attention from researchers and coaches in the last decades[1,2,3,4,5]. Studies that have investigated the effects of prior exercises have used relatively short durations (5-15 min) and intensity varies according to the characteristics of the subsequent exercise. This review aims to analyze studies that investigated the effect of prior exercise on VO2 kinetics and short-duration aerobic performance (~ 2-9 min). Studies with potential relevance, i.e., those that investigated the effects of any type of prior exercise on physiological parameters (e.g., VO2 kinetics response or blood lactate concentration - [La]) and subsequent exercise performance were selected and 93 articles were found. At the end of the search, 36 articles directly related to the central purpose of the study were selected (Figure 1)
