Literature has not shown the minimum time required to recover from muscle fatigue after a prolonged trunk isometric contraction. The purpose of this study was to determine if the lumbar multifidus (LM) and gluteus maximus (GM) muscles would recover from fatigue after three different rest periods following performance of a back extension endurance test. Endurance time and electromyographic (EMG)...

The purpose of this study was to assess the relationships between obesity and measures of back and core muscular endurance in firefighters. Methods. A cross-sectional study was conducted in career firefighters without low back pain. Obesity measures included body mass index (BMI) and body fat percentage assessed with air displacement plethysmography. Muscular endurance was assessed with the Mod...

objective: visfatin, is a novel adipokine, and an adipose tissue-derived hormone shown to correlate with visceral fat mass in patients with obesity. it is not well known whether endurance training – induced change in adipose tissue and blood lipids decreases plasma visfatin or not; thus, the purpose of this study was to examine the effect of 12 weeks endurance training on plasma visfatin in men...

Objective: The aim of this study was to compare the three endurance training intensities on the expression of Perlipin A protein in subcutaneous adipose tissue and pancreatic B-cells function in male diabetic rats. Materials and Methods: In this study, 40 healthy male wistar rats were divided into five groups, including diabetic with low intensity endurance training, diabetic with moderate int...

Objective: RIP140 is one of the proteins that play a role in regulating and metabolizing lipid droplets. The aim of this study was to compare the three endurance training intensities (low, moderate and high) on the expression of RIP140 protein in visceral adipose tissue and insulin resistance in male diabetic wistar rats. Materials and Methods: Forty male wistar rats were assigned to five grou...

introduction exercise is associated with an increase in cortisol - the most important hormone in fat metabolism. cortisol levels vary during a day. this study was conducted in view of the lack of any documents on cortisol levels in endurance athletics in iran. methods in a cross-sectional study, 25 male endurance runners age 18-25 years and 25 non-athlete men were selected. the cortisole and tg...

the purpose of this study was to investigate the effects of 8 weeks of endurance training (et) on ? -1a protein of pre-synaptic p-q-type calcium channels in fhl and soleus muscles of rats. 16 male wistar rats provided from razi institute, were randomly divided to 2 groups (control-sham; n=8 and endurance training; n= 8). training group performed 8 weeks (5 session/week) of endurance training on...

BACKGROUND AND PURPOSE Electrical stimulation has been used to assess skeletal muscle resistance to fatigue. The purpose of this study was to test the hypothesis that 12 weeks of intense endurance exercise training on a bicycle ergometer would reduce the percentage of decline in quadriceps femoris muscle torque during an electrically elicited fatigue test. SUBJECTS AND METHODS Eleven nondisab...
