Evaluation methods and objectives for neuromuscular and hemodynamic responses subsequent to different rest intervals in resistance training: a systematic review

Abstract

Introduction: The training routine planned, and performed correctly results in exercises that, systematically organized, influence the levels of strength, and muscle hypertrophy. However, the magnitudes of these gains vary considerably. To optimize these gains, it is important to underst, and the interaction between training variables such as external load, volume, number of exercises, number of repetitions, duration of repetitions, the order of exercises, number of series, recovery interval between series, and the exercises, as well as the time under tension. The influence of the recovery interval on the response following exercise on neuromuscular components is very important. However, different objectives, and instruments are used to evaluate these responses. Objective: The purpose of this study is to conduct a systematic review of the assessment methods, and objectives for responses after different recovery intervals in strength training. METHODS: The present study is characterized by a systematic review study. Articles found in the following databases were considered for the systematic review: Scopus, PubMed / MEDLINE, Web of Science, Cochrane Library. The following descriptors, and their respective synonyms according to the terms MeSH were used in the databases, both singular, and plural: “Resistance Training”, “Rest Interval”, and “Bech Press”. As filters were used: a) species (humans), and type of study (original). Results: Seven studies were analyzed that met the established criteria. Conclusion: The studies presented have verified the influence of different recovery intervals on muscle, and hemodynamic responses. Evaluating image measurements such as ultrasound, and resonance, blood measurements such as GH, Testosterone, IGF-1, and Lactate, number of repetitions for performance, and fatigue, as well as heart rate, and blood pressure.
