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...

The response of calf-muscle strength, resting blood flow, and postocclusive blood flow (PObf) were investigated after 4 wk of low-load resistance training (LLRT) with and without blood-flow restriction in a matched-leg design. Ten untrained older individuals age 62-73 yr performed unilateral plantar-flexion LLRT at 25% 1-repetition maximum (1RM). One limb was trained with normal blood flow and ...

BACKGROUND: In hemiparetic patients, the skeletal muscle is mainly affected with a combination of abnormalities (denervation, remodeling, spasticity, and eventually muscular atrophy). OBJECTIVE: This study examined role eccentric exercise in strengthening muscles lower extremity ultimately improving autonomy patients post-stroke hemiparesis during gait. METHODS: Thirty-seven adults were recruit...

Muscle strength and power are important requirements in many sports. The correlation of jumping performance as manifestation muscle squatting one-repetition maximum (1RM) has been shown several investigations. Correlations with force a linear isokinetic leg press still pending. Since different testing devices produce relationships rotational measurements show conflicting results, further eviden...

throughout a lifetime is essential for a favorable quality of life. Like most human tissue, skeletal muscle is highly plastic and is capable of responding to a stimulus through a network of anabolic signaling which results in growth and increases in strength. Skeletal muscle functions as the largest disposal site of ingested glucose 1, plays an important role in lipid oxidation 2, 3, and is one...

The purpose of this study was to determine whether the training responses observed with low-load resistance exercise to volitional fatigue translates into significant muscle hypertrophy, and compare that response to high-load resistance training. Nine previously untrained men (aged 25 [SD 3] years at the beginning of the study, standing height 1.73 [SD 0.07] m, body mass 68.9 [SD 8.1] kg) compl...

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 ...

The objective of this study was to compare (i) effects a flywheel and free-weight resistance training program; (ii) performing lateral frontal split squats as part flywheel-resistance program on jumping performance, the 5–0–5 change direction test time, one-repetition maximum (1RM) back squat in soccer players. Twenty-four male amateur players participated were randomly equally assigned one thr...

PURPOSE To compare the metabolic parameters, flexibility, muscle strength, functional capacity, and lower limb muscle power of elderly women with and without the metabolic syndrome (MetS). METHODS This cross-sectional study included 28 older women divided into two groups: with the MetS (n = 14; 67.3 ± 5.5 years; 67.5 ± 16.7 kg; 1.45 ± 0.35 m; 28.0 ± 7.6 kg/m(2)), and without the MetS (n = 14;...
