this study aimed to compare the effects of high intensity and high volume training on lactate accumulation, time performance and vo2peak in 10-14 years old distance runners. 20 male endurance runners aged 12.5±2.32 years old and with a height of 154.62±3.27 cm, weight of 34.5±5.12 kg, maximum heart rate of 207.5±3.1 and vo2max of 36.45±3.22 ml /kg/min took part in the experiment. the experiment...

ôbjective: many studies evaluated the efficacy of exercise on some depression indices, but the effect of physical exercise in exhilarating milieu on urine 3-methoxy-4-hydroxyphenylglycol (mhpg) sulfate-the main metabolite of norepinephrine is not clear. the purpose of this research was to study the effect of a six-week intermittent walking in the water on 24-hour urine mhpg sulfate in depressed...

The purpose of this study is to evaluate whether the range of motion exercise of the temporo-mandibular joint (jaw ROM exercise) with a hot pack and massage of the masseter muscle improve biting disorder in Duchenne muscular dystrophy (DMD). The subjects were 18 DMD patients (21.3+/- 4.1 years old). The jaw ROM exercise consisted of therapist-assisted training (2 times a week) and self-training...

This study evaluated cardiopulmonary and metabolic responses to maximum exercise and aerobic capacity in hemiplegic patients and clarified the relationship between the resulting data and motor disability. Twenty patients with stroke and fifteen healthy controls were included in the study. Cardiopulmonary and metabolic responses to maximum exercise were investigated with an electronically braked...

TO THE EDITOR: We read with interest the Point:Counterpoint opinion piece titled “Pulmonary edema does/does not occur in human athletes performing heavy sea-level exercise” (3). We do not think there is much debate to this opinion piece. Several studies using healthy human subjects (2, 4, 5, 7) demonstrate evidence of pulmonary edema from sea-level exercise. In a recent review (6), 51 of 78 sub...

The purpose of this study was to examine the effect of exercise-induced damage of the elbow flexor muscles on steady motor performance during isometric, shortening, and lengthening contractions. Ten healthy individuals (age 22+/-4 yr) performed four tasks with the elbow flexor muscles: a maximum voluntary contraction, a one repetition maximum (1 RM), an isometric task at three joint angles (sho...

Noise-robust speech recognition has become an important area of research in recent years. In current speech recognition systems, the Mel-frequency cepstrum coefficients (MFCCs) are used as recognition features. When the speech signal is corrupted by narrow-band noise, the entire MFCC feature vector gets corrupted and it is not possible to exploit the frequency-selective property of the noise si...

BACKGROUND We evaluated exercise-induced changes in the profile of circulating cytokines and growth factors in patients with AS. METHODS We studied 32 consecutive asymptomatic moderate-to-severe AS patients and 32 age and sex-matched controls. Plasma levels of interleukin (IL)-6, IL-10, hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), and transforming growth factor (...

We examined the effect of exercise intensity and mode on the acute responses of free testosterone to cortisol ratio and salivary α-amylase. We also evaluated the relationship between cortisol and salivary α-amylase. Ten healthy young active males participated voluntarily in this study in six single sessions. They exercised on a cycle ergo meter, treadmill, and elliptical instrument at intensiti...

A reduced exercise tolerance, maximum oxygen uptake (VO2max), and anaerobic threshold have been reported after lung transplantation (LT). We prospectively assessed the hemodynamic responses to incremental cycle ergometry before and after LT in eight recipients. All recipients underwent a 6-week formal exercise training program. The VO2max increased after versus before LT (13.4 +/- 0.8 vs 9.2 +/...
