recently, the role of myostatin (mstn) in controlling insulin resistance (ir( has been known. the aim of this study was to determine acute and delayed response of mstn and ir to circuit resistance exercise. for this purpose, 12 healthy men volunteered and participated in 2 sessions of the resistance exercise and control with one-week interval. after a session to instruct how to perform resistan...
PURPOSE This study examined cycling economy before and after 8 wk of maximal leg-strength training. METHODS Seven previously untrained males (25 +/- 2 yr) performed leg-strength training 3 d.wk(-1) for 8 wk using four sets of five repetitions at 85% of one repetition maximum (1RM). Body mass, lean-leg muscle mass (LLM), percentage of body fat, and leg strength (1RM) were measured at 0, 4, and...
However the effects of endurance training on respiratory system is approved somedeal but, few and contradictory evidence exist concerning resistance training (RT), so the purpose of this research was therefore to study effects of eight weeks circuit RT (CRT) on pulmonary function of inactive women. Nineteen volunteer healthy inactive women were randomly divided into 2 groups: without tra...
in the past couple of decades sociocultural theory of sla and its implications in efl contexts have attracted attentions of research circles worldwide and aroused some controversies. firth and wagner (1997) have questioned the principles of the cognitive view which gives importance to mental constructs in favor of sociocultural view which highlights social and contextual constructs. but if soci...
[Purpose] The purpose of the present study was to determine whether vibrations should be applied before resistance exercises by examining changes in stress hormone levels with vibrations applied before different exercise intensities. [Subjects] Eighteen male subjects in their 20s were included, and were randomly divided into one-repetition maximum (1RM) 50% group (50% RMG, n = 6), 1RM 70% group...
This study compared physical characteristics (body height [BH], body mass [BM], body fat [BF], and fat free mass [FFM]), one repetition maximum bench press (1RM (BP)), jumping explosive power (VJ), handball throwing velocity, power-load relationship of the leg and arm extensor muscles, 5- and 15-m sprint running time, and running endurance in elite (n = 16; EF) and amateur (n = 15; AF) female h...
The study aim was to determine relationships between mechanical variables in the one-repetition maximum (1RM) traditional bench press (TBP) and close-grip bench press (CGBP). Twenty resistance-trained men completed a TBP and CGBP 1RM. The TBP was performed with the preferred grip; the CGBP with a grip width of 95% biacromial distance. A linear position transducer measured: lift distance and dur...
The purpose of the present study was to compare the changes in muscle strength in nontrained young males performing resistance training under different supervision ratios. One hundred twenty-four young men were randomly assigned to groups trained under a high (HS, 1:5 coach to athlete ratio) or low (LS, 1:25) supervision ratio. Both groups performed identical resistance training programs. Subje...
The purpose of this study was to examine the effect of knee extensor and ankle plantar flexor fatigue on dynamic balance among active elderly males. Fifteen healthy individuals having age of 72±6.57 years, height of 168.4±4.8 cm and weight of 70.5±7.4 kg without history of injuries at lower extremity, participated in this study. Knee extensor and ankle plantar flexor muscles fatigued with f...
OBJECTIVE This study aimed to determine the optimal Foley catheter balloon volume (30-mL vs. 80-mL) and the maximum time for cervical ripening (12 hours vs. 24 hours) to improve vaginal delivery rate within 24 hours of induction. METHODS We conducted an open-label, randomized controlled trial in a teaching hospital in China. Women with a term singleton pregnancy, cephalic presentation, intact...
