Effect of resistance exercise on cardiac perturbations and systolic performance: A cross-over randomized trial comparing volumes and techniques.

This study investigated the magnitude and time-course of resistance exercise (RE) technique induced transient cardiac perturbations. Twenty-four participants were assigned to one of four arms: sets to failure or non-failure with 8-10 repetition maximum (RM), and sets to failure or non-failure with 15RM. Echocardiographic and blood pressure (BP) data were recorded at baseline and 30 min, 6 h and 24 h post-exercise.

High-intensity interval training ameliorates endothelial dysfunction through adropin, nitric oxide, MR-proADM, and copeptin changes in overweight subjects.

Purpose: The purpose of this study was to determine adropin, NO, MR-proADM, and copeptin changes following four different types of high-intensity interval training (HIIT) in men with overweight.

Methods: In the current study, 45 overweight participants were included in the pre-intervention assessments and randomly assigned to the following groups: (1) control, (2) HIIT bike, (3) HIIT short-treadmill, and (4) HIIT long-treadmill groups. The participants were given 10-min sessions of HIIT intervention between 85 and 95% of VO, followed by 1-min inactive recovery at three sessions/week for 8 weeks.

Preconditioning intensive training ameliorates reduction of transcription biofactors of PGC1α-pathway in paretic muscle due to cerebral ischemia.

Exercise training increases fibronectin type III domain-containing protein 5 (FNDC5/irisin) via the peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α)-pathway. The PGC1α pathway induced FNDC5/irisin changes in response to exercise training and ischemic stroke are not entirely understood. We investigated the relation of the PGC-1α/FNDC5/irisin pathway to exercise training and to the pathophysiology of ischemic stroke in paretic muscles of stroke-induced rat models.

The impact of high-intensity interval training on postprandial glucose and insulin: A systematic review and meta-analysis.

Aims: We performed a systematic review and meta-analysis to investigate the effects of high-intensity interval training (HIIT) on postprandial glucose (PPG) and insulin (PPI) versus non-exercise control and moderate-intensity continuous training (MICT) in participants with both normal and impaired glucose.

Methods: The PubMed, Scopus, and Web of Science electronic databases were searched up to October 2021 for randomized trials evaluating HIIT versus control and/or versus MICT on glucose and insulin AUC using oral glucose tolerance testing. Subgroup analyses based on intervention duration (short-duration < 8 weeks, moderate-duration ≥ 8 weeks), baseline glucose levels (normal glucose and impaired glucose) and type of HIIT (L-HIIT and SIT) were also conducted across included studies.

Effect of resistance training with and without caloric restriction on visceral fat: A systemic review and meta-analysis.

We performed a systematic review and meta-analysis to investigate the effect of resistance training (RT) with and without caloric restriction (CR) on visceral fat (VF). PubMed and Scopus were searched to identify original articles published through December 2020. Standardized mean differences and 95% confidence intervals (95% CIs) were determined, and separate analyses were conducted for RT versus control, and RT plus CR versus CR only.

Voluntary wheel running promotes improvements in biomarkers associated with neurogenic activity in adult male rats.

In rodents, hippocampal neurogenesis and synaptogenesis phenomena are affected by exercise. However, the role of exercise parameters such as intensity, duration, and mode on molecular mechanisms involved in these processes has not been elucidated. In this study, we evaluated the effects of different intensities and modes of running on the expression of genes contributing to neuronal differentiation and synapse formation in the hippocampus of adult male rats.

Taurine with combined aerobic and resistance exercise training alleviates myocardium apoptosis in STZ-induced diabetes rats via Akt signaling pathway.

Aim: The aim of this study was considering the effects of taurine supplementation with combined aerobic and resistance training (CARE) on myocardial apoptosis and Protein Kinase B (akt) level changes in diabetic rat.

Main Methods: Forty male Wistar rats were randomly divided in to 5 groups of 8 animals in each: 1) control, 2) Diabetes Mellitus (DM), 3) DM with taurine supplementation (DM/T), 4) DM with CARE (DM/CARE), and 5) DM with combination of taurine and CARE (DM/T/CARE). DM was induced by injection of streptozotocin (STZ) and nicotine amid (NA) for 2, 3, 4 and 5 groups.

Efficacy of Vitamin D Supplementation in Physical Performance of Iranian Elite Athletes.

Background: There has been no report of the vitamin D status of the professional athletes from Iran to date. This study was performed to evaluate the efficacy of weekly vitamin D supplementation on athletic performance in Iranian athletes expedited to Asian competition in Taipei, China, 2015.

Methods: This study was a randomized controlled clinical trial.

Effects of six weeks of resistance-endurance training on microRNA-29 expression in the heart of ovariectomised rats.

Introduction: Heart disease risk rises with age. However, women's symptoms become more pronounced following the onset of menopause. The aim of the present study was to evaluate the effects of six weeks of combined resistance-endurance (RE) training on microRNA-29 expression in the heart of ovariectomised rats.

Effect of combined endurance-resistance training and soy extract supplementation on expression of eNOS gene in ovariectomized rats.

Introduction: Menopause is an independent risk factor for cardiovascular disease (CVD). Physical exercise and soybean diets have been suggested to reduce the risk of CVD in postmenopausal women. The purpose of this study was to investigate the effects of combined resistance and endurance (RE) training and soy extract (SOY) supplementation, both known to improve endothelial function, on expression of the eNOS gene in the heart of ovariectomized (OVX) rats.

Possible role for growth hormone in suppressing acylated ghrelin and hunger ratings during and after intermittent exercise of different intensities in obese individuals.

Body weight is influenced by both food intake and energy expenditure. Acylated ghrelin enhances appetite, and its circulating level is suppressed by growth hormone. Data on the acylated ghrelin responses to exercise of different intensities in obese individuals are currently not available.
