Aim: To verify the response of tissue saturation index (TSI) during ischemia-reperfusion (IR) interventions with different cuff-pressures. Methods: Twenty-nine healthy men experienced in resistance training were recruited. Each one has undergone a control condition (no cuff) and one of the three IR interventions: 1) 190 mmHg (CP-190, 22.7 ± 3.0 yea...

The outbreak of the new Coronavirus and the sudden lockdown promoted alternative approaches for health care procedures, such as telemedicine and telerehabilitation appointments. The establishment of social distancing as the "new normal" and use of technologies became necessary for remote online activities (i.e., school, work, leisure and shopping)....

Performance Expectation, Anxiety, and Motivation of Triathletes and Swimmers during Different Lockdowns Stages in Covid-19 Pandemic. JEPonline 2022;25(4):75-83. The purpose of this study was to analyze the levels of anxiety during...

Há um consenso de que um suplemento nutricional é ergogênico quando estudos revisados por pares demonstram que este, após semanas a meses de ingestão, melhora significativamente o desempenho físico. Embora o uso de uma variedade de suplementos seja amplamente difundido no mundo dos esportes, apenas alguns demonstram evidências científicas que suste...

Instagram (IG) reaches millions of people, sharing personal content and all kinds of information, including those related to exercise and health. However, the scientific quality of the posted information is questionable. Thus, this study aimed to analyze whether exercise and health information posted by popular Brazilian IG influencers has technica...

Paes ST, Scapim SN, Arriel RA, Meireles A, Marocolo M. Main Source of Information Regarding Physical Activity Among Physically Active Brazilian People. JEPonline 2021;24(5):23-28. This study investigated the main sources of information that people who exercise outdoors use to learn about physical activity (PA). The study sample consisted of 418 phy...

RESUMO: O pré-condicionamento isquêmico [do termo em inglês ischemic preconditioning (IPC)] é uma estratégia caracterizada por breves ciclos de restrição do fluxo sanguíneo seguidos de reperfusão, realizados nos membros superiores ou inferiores com o objetivo de melhorar o desempenho físico. Essa intervenção tem chamado atenção devido a sua caracte...

Instagram (IG) reaches millions of people, sharing personal content, and also all kinds of information, including those related to exercise and health. However, scientific quality of the posted information is questionable. Thus, this study aimed at analyzing whether exercise and health information posted by main IG Brazilian influencers have techni...

Abstract: It has been demonstrated that brief cycles of ischemia followed by reperfusion (IR) applied before exercise can improve performance and, IR intervention, applied immediately after exercise (post-exercise ischemic conditioning—PEIC) exerts a potential ergogenic effect to accelerate recovery. Thus, the purpose of this systematic review with...

We read with interest the recent Viewpoint by Ferrandi, Alway, and Mohamed (1) on the interaction between SARS-CoV-2 and ACE2 with skeletal muscle, and although several relevant points were raised, we would like to present some elements to enrich the debate. Pathologies that affect directly the skeletal muscle (e.g., Duchenne muscular dystrophy) or...

Aims: To evaluate whether body mass (BM) and body composition may influence mountain bike cycling performance. Methods: Forty male amateur mountain bikers attended the laboratory on two non-consecutive days. At the first visit, anthropometric measures (height, BM, body fat [BF], fat-free mass [FFM] and body mass index [BMI]) and familiarization to...

Background: Previous studies have assessed the effects of ischemic preconditioning (IPC) on exercise performance and physiological variables, such as lactate and muscle deoxygenation. In this study, we verified the IPC effects on heart rate and performance during and immediately after a maximal incremental cycling test. Methods: Eighteen recreat...

Introduction: Regular practice of resistance training offer positive results on muscular and physical performance. Thus, some strategies have been developed to influence the increase of performance results. Therefore, the objective of this study was to verify the influence of music, placebo supplementation and biofeedback on the number of execution...

Several studies have reported that high doses of synthetic anabolic androgenic steroids (AAS) can have serious negative effects on health, including the cardiovascular system. The aim of this study was to evaluate the combined effects of AAS and exercise training on ventricular repolarization and cardiac autonomic modulation in rats. Male Wistar ra...

Anxiety is the main emotion, which influences life quality and competitive performance. The purpose of this study was to evaluate anxiety levels on different training phases during a semester season and to analyze the relation between anxiety and athletic training of adolescent swimmers. Twenty swimmers were included, 13 men with an average age of...

Introdução: O pré-condicionamento isquêmico [do termo em inglês ischemic preconditioning (IPC)] é caracterizado por breves momentos de oclusão vascular seguido por reperfusão. Embora concebido na área clínica, quando inserido na área esportiva, o IPC mostrou efeitos positivos sobre o desempenho físico. Entretanto, a influência no desempenho do exer...

Experiment carried out with people with diabetes, through an intervention which consisted of physical and psychological activities. The goal was to verify if performing an intervention would have any impacts on improving the anxiety in the individuals. Anxiety is an emotion associated with diabetes which can impair the glycemic control and affect t...
