Efficacy and costs of 3 levels of medical-behavioral treatment intensity in conjunction with nicotine replacement therapy (NRT) were compared in 240 one-pack-a-day smokers: (a) a low-intensity (LI) group that received 8 weeks of NRT (n = 80) and 1 advice and education (A&E) session with a nurse practitioner (NP); (b) a moderate-intensity (MI) group that was provided NRT and 4 A&E sessions with ...

purpose: doing plyometric training with and without the vessel occlusion is an effective practice for rapid increase of muscles strength their hypertrophy. we evaluated the effects of plyometric training with and without the vessel occlusion on electromyographic parameters. methods: in this quasi-experimental study, 22 females were selected through convenience sampling method. they were randoml...

BACKGROUND The relative benefit of higher statin dosing in patients with peripheral artery disease has not been reported previously. We compared the effectiveness of low- or moderate-intensity (LMI) versus high-intensity (HI) statin dose on clinical outcomes in patients with peripheral artery disease. METHODS AND RESULTS We reviewed patients with symptomatic peripheral artery disease who unde...

The hemodynamics of light-load exercise with an applied blood-flow restriction (BFR) have not been extensively compared between light-intensity, BFR, and high-intensity forms of both resistance and aerobic exercise in the same participant population. Therefore, the purpose of this study was to use a randomized crossover design to examine the hemodynamic responses to resistance and aerobic BFR e...

The purpose of the current study was two-fold: (1) To examine the variation in velocity and power with increasing intensity in the back squat among subjects; and (2) To explore individual subject characteristics as possible explanations for variations of velocity in the back squat. Fourteen recreationally trained male subjects with experience in the back squat agreed to participate in the study...

The purpose of this study was to examine the power-strength curve in a half squat exercise in trained basketball players of the EBA league. For that, a cross sectional, descriptive study was carried out to 8 high-level male basketball players. After controlling the participants 1RM, a progressive test, consisted on moving loads of 30, 45, 60, 70 and 80% of 1RM as fast as possible in the concent...

the aim of this study was to determine the effects of circuit resistance training with different intensities on plasma ghrelin and gh in non–athlete young women. for this purpose, 20 young women were voluntarily selected and randomly divided into four experimental and control groups. experimental groups were three groups who performed the protocol with intensity of 40% 1rm (group 1), %60 1rm (g...

Purpose: Doing plyometric training with and without the vessel occlusion is an effective practice for rapid increase of muscles strength their hypertrophy. We evaluated the effects of plyometric training with and without the vessel occlusion on electromyographic parameters. Methods: In this quasi-experimental study, 22 females were selected through convenience sampling method. They were random...

A single bout of high-intensity resistance exercise is capable of activating the expression of various genes in skeletal muscle involved in hypertrophy such as myosin heavy chain (MHC) isoforms, myogenic regulatory factors (MRFs), and growth factors. However, the specific role exercise intensity plays on the expression of these genes is not well defined. The purpose of this study was to investi...
