The effect of graded doses of pentagastrin on the gastric scretion of acid was compared in patients with and without gastritis. Biopsies were taken from the body of the stomach. Ten subjects had normal gastric mucosa, eight had superficial gastritis, and 10 atrophic gastritis. Pentagastrin in a dose of 1.5 mug/kg/hr elicited a near maximal HCl response from both the normal gastric mucosa and th...

results the means ± standard deviations of the averaged emg during the lateral and frontal wp exercises were 40.1 ± 19.1, and 23.7 ± 11.3 µv, respectively. those of the percent maximal voluntary contraction during the lateral and frontal wp exercises were 51.4 ± 29.7, and 31.3 ± 20.5, respectively. gmax activity during the lateral wp exercise was significantly higher than that during the fronta...

introduction: spinal malalignment is a common problem in the present societies and forward head posture is one of the most common dysfunction in cervical region. the purpose of the present study is to evaluate effect of stabilization exercises in improving of forward head posture. materials and methods: twenty six female students with forward head posture in age range of 20-27 years old partici...

PURPOSE The aim of this study was to evaluate the power output (PO) during the cycle phase of the Beijing World Cup test event of the Olympic triathlon in China 2008. METHODS Ten elite triathletes (5 females, 5 males) performed two laboratory tests: an incremental cycling test during which PO, HR at ventilatory thresholds (VT1 and VT2), and maximal aerobic power (MAP) were assessed, and a bri...

This study aimed to investigate mechanisms of neuromuscular fatigue during maximal concentric and isometric leg extensions inducing similar torque decrements. Nine physically active men performed two separate fatiguing sessions maintained until similar torque decreases were obtained. The first session, only conducted under isokinetic concentric conditions (CON), consisted of three series of 30 ...

J Strength Cond Res 35(6): 1484–1490, 2021—The purpose this study was to investigate influence ankle, knee, hip net joint moments (NJMs), relative muscular effort (RME), vertical ground reaction forces (GRFs) exercises, such as midthigh pull. Eigh...

Background/Objective The heart rate (HR) and metabolic (VO2) responses to treadmill running using the GlideTrak™ body weight support system have not been reported. The purpose of this study was to compare the submaximal and maximal HR and VO2 responses to normal-weight treadmill running (TMR) to treadmill running with body weight support provided by the GlideTrak™ (GTR). Methods Twenty partic...

Purpose: The present study aimed to investigate the effect of voluntary and electrically stimulated quadriceps muscle fatigue on postural control. Methods: Sixteen healthy young males participated in this quasi-experimental study. All subjects performed two fatiguing exercises with equal intensity of isometric maximal voluntary contraction: Voluntary (VOL) and Electrical Stimulation (ES). The ...
