Eight mature (12 +/- 2 yr; MAT) and 5 older (22 +/- 2 yr; OLD) Standardbred mares were used to test the hypothesis that aging and exercise training would alter apoptosis in white blood cells and antioxidant status. The horses were housed indoors overnight (16 h/d) in 3 m x 3 m stalls and were turned out in a drylot during the day. They were fed a diet consisting of total mixed ration, hay cubes...
A percentage of either measured or predicted maximum heart rate is commonly used to prescribe and measure exercise intensity. However, maximum heart rate in athletes may be greater during competition or training than during laboratory exercise testing. Thus, the aim of the present investigation was to determine if endurance-trained runners train and compete at or above laboratory measures of 'm...
SUMMARY This study was undertaken to compare the incidence of electrocardiographic abnormalities associated with a near maximal and a maximal exercise test, because of previous reports of high incidence of such abnormalities among older men. One hundred fourteen male volunteers ranging in age from 40 to 75 years were studied by both near maximal and maximal exercise testing. All subjects were c...
چکیده هدف از این پژوهش بررسی تاثیر مصرف مکمل عسل روی عوامل التهابی مردان جوان هندبالیست به دنبال یک فعالیت بدنی وامانده ساز بود. بدین منظور 30 نفر از هندبالیست های مرد جوان (سن2±17، قد9±180 ، وزن20±79، ضربان قلب 18±172 و حداکثر اکسیژن مصرفی 09/5 ±06/49) به صورت تصادفی انتخاب و در سه گروه مصرف مکمل عسل+ فعالیت بدنی شدید، مصرف مکمل نما+ فعالیت بدنی شدید و مصرف مکمل عسل قرار گرفتند. آزمودنی های گ...
OBJECTIVE The Genes for Treatment study is an international, multisite collaboration exploring the role of genetic, demographic, and clinical predictors in response to cognitive-behavioral therapy (CBT) in pediatric anxiety disorders. The current article, the first from the study, examined demographic and clinical predictors of response to CBT. We hypothesized that the child's gender, type of a...
BACKGROUND Quercetin is a health-enhancing antioxidant bioflavonoid (1-3). This flavonoid occurs in variety of natural fruits and vegetables such as apple, cranberry, onion, broccoli, and teas. Many studies have shown that quercetin has possible positive effects on exercise performance. The aim of this study is the evaluation of effects of quercetin supplementation on VO2max and exercise perfor...
PURPOSE The objectives of this study were to examine the effect of 4-week moderate- and high-intensity interval training (MIIT and HIIT) on fat oxidation and the responses of blood lactate (BLa) and rating of perceived exertion (RPE). METHODS Ten overweight/obese men (age = 29 ±3.7 years, BMI = 30.7 ±3.4 kg/m(2)) participated in a cross-over study of 4-week MIIT and HIIT training. The MIIT tr...
BACKGROUND We previously reported an association between 5HTTLPR genotype and outcome following cognitive-behavioural therapy (CBT) in child anxiety (Cohort 1). Children homozygous for the low-expression short-allele showed more positive outcomes. Other similar studies have produced mixed results, with most reporting no association between genotype and CBT outcome. AIMS To replicate the assoc...
The extraction of the response from field fluctuations excited by random sources has received considerable attention in a variety of different fields. We present three methods for the extraction of the systems response that are based on cross-correlation, deconvolution, and the solution of an integral equation, respectively. For systems that are invariant for time-reversal the correlation metho...
