Using velocity loss for monitoring resistance training effort in a real world setting

The purpose of the present study was to evaluate the changes in movement velocity during resistance training with different loads while the trainees are attempting to move the load at a pre-determined repetition duration. Twenty-one resistance-trained men (age: 25.7 ± 5 years; height: 177.0 ± 7.2 cm; mass: 85.4 ± 13.56 kg) volunteered to participate […]

Fatigue and perceptual responses of heavier- and lighter-load isolated lumbar extension resistance exercise in males and females

Background There is a lack of research considering acute fatigue responses to high- and low-load resistance training as well as the comparison between male and female responses. Furthermore, limited studies have considered fatigue response testing with the inclusion of perceptions of discomfort and exertion. Methods The present study included males (n = 9; 23.8 ±

Similar acute physiological responses from effort and duration matched leg press and recumbent cycling tasks

The present study examined the effects of exercise utilising traditional resistance training (leg press) or ‘cardio’ exercise (recumbent cycle ergometry) modalities upon acute physiological responses. Nine healthy males underwent a within session randomised crossover design where they completed both the leg press and recumbent cycle ergometer conditions. Conditions were approximately matched for effort and duration

Knowledge about sport and exercise science: a cross-sectional survey among health professionals in Brazil

Purpose The aim of this study was to assess the knowledge on sport and exercise science held by a sample of Brazilian physiotherapists, nutritionists and physical educators. Design/methodology/approach A cross-sectional research design was used. The answers given by 1,147 professionals (300 physiotherapists, 705 physical educators and 142 nutritionists) who participated in a qualifying process for

Defining the number of bouts and oxygen uptake during the “Tabata protocol” performed at different intensities

It is usually reported that the Tabata protocol (TP) is performed with eight bouts of 20:10 intervals at a load equivalent to 170% of iVO2max. However, the feasibility of accumulating 160s of work at 170% iVO2max has been questioned. This article tested the intensity that would allow the performance of the original TP on a

Resistance training with single vs. multi-joint exercises at equal total load volume: effects on body composition, cardiorespiratory fitness and muscle strength

The present study aimed to compare the effects of equal-volume resistance training performed with single-joint (SJ) or multi-joint exercises (MJ) on VO2max, muscle strength and body composition in physically active males. Thirty-six participants were divided in two groups: SJ group (n = 18, 182.1 ± 5.2, 80.03 ± 2.78 kg, 23.5 ± 2.7 years) exercised with

Ability to predict repetitions to momentary failure is not perfectly accurate, though improves with resistance training experience

Repetitions in Reserve’ (RIR) scales in resistance training (RT) are used to control effort but assume people accurately predict performance a priori (i.e. the number of possible repetitions to momentary failure (MF)). This study examined the ability of trainees with different experience levels to predict number of repetitions to MF. One hundred and forty-one participants

Comparison of elbow flexor isokinetic peak torque and fatigue index between men and women of different training level

The purpose of the study was to compare elbow flexion peak torque (PT) and fatigue index (FI) during isokinetic concentric contractions in men and women with different training levels. Sixty-eight young men and women were divided into four groups: resistance trained men (RTM), non-resistance trained men (NRTM), resistance trained women (RTW) and non- resistance trained

High Resistance Training Volume and Low Caloric and Protein Intake Are Associated with Detrimental Alterations in Body Composition of an Amateur Bodybuilder Using Anabolic Steroids: A Case Report

Many bodybuilders use anabolic androgenic steroids (AAS) to potentiate muscle mass gain as a result of specific resistance training and nutrition. The case we describe hereafter outlines alterations in body composition of an amateur bodybuilder during his pre-competitive period (11 weeks). The Participant was a 28-year old Caucasian male who was aiming to participate in
