Background Resistance training is hardly recommended for postmenopausal women to counteract negative effects of hormonal changes. However, some concern exists about the marked hemodynamic responses caused by high-load resistance exercises. In this regard, studies on young, healthy, physically active individuals suggest that set configuration can mo...

INTRODUCTION: Menopause is a critical phase in women’s health, increasing the risks of hypertension and vascular dysfunction (1). Resistance exercise (RE) can promote a post-exercise hypotensive response in postmenopausal women (2). Set configuration can modulate the acute cardiovascular response to RE (3,4). However, menopause may influence the ac...

Introduction. During a resistance exercise session (RE), the set duration and the number of sets shape the blood pressure (BP) response to a greater extent than the load (Gjøvaag et al., 2016; Lamotte et al., 2005). Hence, set configuration (i.e., the repetitions performed with respect to the maximum feasible number in a set (Iglesias-Soler et al.,...

La configuración de la serie se presenta como una variable capaz de modular las respuestas cardiovasculares al entrenamiento de fuerza (Figueiredo et al., 2015; Rúa-Alonso et al., 2020) pero las posibles adaptaciones a largo y medio plazo casi no se han explorado (de Sousa Fortes et al., 2017). Por ello, el objetivo de este estudio fue determinar l...

The purpose of this study was to determine the effects of training load (25% vs. 75% of one repetition maximum (1RM)) and fatigue (failure vs. non‐failure) during four weeks of unilateral knee extension resistance training (RT) on maximal voluntary force in the trained and the untrained knee extensors. Healthy young adults (n=42) were randomly assi...

INTRODUCTION Cluster training is defined as a set configuration in which rest periods are more frequent than traditional protocols (1). It has been suggested as a method for allowing each repetition of the set to be performed with the highest quality (2). By the manipulation of set configuration is possible to improve the velocity of training while...

Introduction Cross education (CE) consists in strength transfer from trained to non-untrained limb after an unilateral strength training program (3). Neural adaptations are suggested as responsible of CE phenomenon (4), and it seems that characteristics of load are determinant in order to obtain significant improvements. The aim of this study was t...

INTRODUCTION Resistance exercise produces a sudden increase in blood pressure (BP), so trainers should be careful when provide training in special populations. Many studies have shown that the length of the set determines the response of BP, with higher levels with each subsequent repetition and a peak occurring prior to muscular failure. In additi...
