The purpose of this study was to determine the effects of an alleged aromatase and 5-α reductase inhibitor (AI) on strength, body composition, and hormonal profiles in resistance-trained men. Thirty resistance-trained men were randomly assigned in a double-blind manner to ingest 500 mg of either a placebo (PL) or AI once per day for 8 wk. Participants participated in a 4-d/wk resistance-trainin...

Introduction: Obese individuals have elevated levels of inflammatory and cell adhesion molecules that can critically induce the occurrence of atherosclerosis. Aerobic exercise training reduces biochemical markers and anthropometric characteristics involved in atherosclerosis. However, little is known about the effect of resistance exercise training on these biomarkers. This study aimed to inves...

The present study investigated the accumulated oxygen deficit (AOD) method to assess the energy cost in resistance exercises (RE). The aim of the study was to evaluate the aerobic and anaerobic energy release during resistance exercises performed at 80% 1-RM in four exercises (half squat, bench press, triceps extension and lat pull down), as well as the accuracy of its estimation. The sample co...

This study examined whether supplementing the diet with a commercial supplement containing zinc magnesium aspartate (ZMA) during training affects zinc and magnesium status, anabolic and catabolic hormone profiles, and/or training adaptations. Forty-two resistance trained males (27 +/- 9 yrs; 178 +/- 8 cm, 85 +/- 15 kg, 18.6 +/- 6% body fat) were matched according to fat free mass and randomly a...

The effect of oral L-ornithine hydrochloride (0.1 g/kg BW) on energy expenditure during a rest period from 120 to 180 min after resistance exercise was evaluated by indirect calorimetry. Healthy male subjects who have no habit of resistance training underwent resistance exercise (chest press, lat pulldown, leg press, shoulder press, leg extension, and leg curl), with 3 sets of each exercise and...

The influence of internal (movement focus) and external (outcome focus) attentional-focusing instructions on muscular endurance were investigated using three exercise protocols with experienced exercisers. Twenty-three participants completed a maximal repetition, assisted bench-press test on a Smith's machine. An external focus of attention resulted in significant (p < .05) improvements in perf...

While regular exercise training is associated with numerous health benefits, a single bout of physical exercise has been shown to induce inflammatory process and cellular damage. However, natural supplementation may attenuate these in athletes. Hence, the present study was conducted to assess the effect of BCAA supplementation on serum C reactive protein, creatine kinase (CK) after acute resist...

Free weights are dumbbells and barbells that are used without the external support of a machine. Major lifts are lifts used in the sports of weight and power lifting. Also used are the power clean and the incline and overhead presses. These lifts involve the use of free weights lifted through the extremes of joint motion in a ballistic rather than a controlled fashion. They have significant pot...

OBJECTIVES To determine the effect of 26 weeks of low-load high-repetition resistance training (BodyPump™) on maximal strength, gait speed, balance and self-reported health status in healthy, active middle-aged and older adults. DESIGN Two-group randomised control trial. METHODS Sixty-eight apparently healthy, active adults aged over 55 years completed either 26 weeks of BodyPump™ training ...
