this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
OBJECTIVE To compare, retrospectively, the values of maximum heart rate (MHR) and the decrease of the heart rate at the first minute of recovery, which were obtained in an exercise test (ET) performed in two different ergometers and at different moments. METHODS Sixty individuals (from 29 to 80 years old), submitted to cardiopulmonary ET in a cycle of lower limbs (CLL) in our laboratory and w...
Background: The purpose of this study was to determine the effect of a period of combined exercise training on the plasma leptin level and hormonal factors in overweight men. Materials and Methods: The subjects of this research consisted of thirty males (22-42 years old, BMI ≥29) who randomly were divided into experimental (n=15) and control groups(n=15). The experimental group performed fo...
the purpose of this study was to examine the effects of omega3 and aerobic exercise intervention on the calcium metabolism regulating hormones in non – athlete postmenopausal women. for this purpose 40 healthy non – athlete postmenopausal women with age 57.72±3.53 years, height 157,75±9,24 cm, weight 58.08±12.76kg, bmi 23.78±3.73kg/m2, fat 23.18±4.68% volunteered in this study. subjects in a do...
چکیده معضل چاقی به عنوان عارضه ای جدی برای زندگی بی تحرک و ماشینی، مورد توجه اغلب مراکز بهداشتی و درمانی دنیا قرار گرفته است. چاقی عامل زمینه ساز و در واقع عامل خطری برای بروز بیماری های قلبی - عروقی است که عموماً با کاهش طول عمر مورد انتظار و افزایش بیماری همراه است. هدف پژوهش حاضر تأثیر 12 هفته تمرینات ویبریشن کل بدن، تمرینات هوازی و تمرینات ترکیبی( هوازی و ویبریشن کل بدن) بر ترکیب بدنی زنان ...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
CRF is the most frequently reported symptom affecting up to 90% of cancer patients. CRF is distinguishable from normal tiredness in that CRF symptoms are severe, distressing, and are not relieved by rest or sleep. While the mechanisms and contributing factors that lead to CRF are unclear, good evidence exists for promoting exercise as an intervention to combat CRF. Currently, more than 20 RCTs ...
BACKGROUND The Mean Heart Rate (MHR) tends to decrease with age. When adjusted for gender and diseases, the magnitude of this effect is unclear. OBJECTIVES To analyze the MHR in a stratified sample of active and functionally independent individuals. METHODS A total of 1,172 patients aged > 40 years underwent Holter monitoring and were stratified by age group: 1 = 40-49, 2 = 50-59, 3 = 60-69...
Maximal treadmill exercise heart rate, work capacity and electrocardiographic response were studied in 95 asymptomatic, predominantly sedentary women between the ages of 19 and 69 years. Average maximal heart rate (MHR) was found inversely related to age, such that MHR = 216 -0.88 (years of age) +/- 10 beats/min (X +/- 1 SD). Treadmill exercise endurance was 7.64 min +/- 1.99. The reduction of ...
OBJECTIVE To assess maternal rectal temperature and fetal heart rate responses to dynamic exercise. METHODS 11 healthy women with low risk pregnancies completed three separate upright cycling tests at 34 to 37 weeks gestation: 15 min at 62.5 W (mean maternal heart rate [MHR] 138 beats.min-1 (test A); 15 min at 87.5 W (MHR 156 beats.min-1) (test B); and 30 min at 62.5 W (MHR 142 beats.min-1) (...
