هدف پژوهش حاضر با بررسی اثرات تمرین تناوبی شدید در شرایط هایپوکسی (14o2%( و نورموکسی (21o2%( بر لکوسیت ها و سلول های خونی به پاسخ فعالیت وامانده ساز بود. 16 مرد فعال (سن 94/2±27/23 سال، قد 86/5±13/178 سانتی متر، وزن 87/7 ±06/74 کیلوگرم، چربی بدن 70/3±33/19 درصد) به طور تصادفی به دو گروه فعالیت در شرایط هایپوکسی (%14o2) و نورموکسی (%21o2) تقسیم شدند. پیش از شروع تمرین، آزمودنی ها آزمون واماندهس...
OBJECTIVE The aim of the present study was to examine the correlation between 1-legged bicycling and the 6-minute walk test (6MWT) in subjects post-stroke. A further aim was to analyse the relationship between specific stroke impairment and walking endurance. PARTICIPANTS Thirty-four subjects (mean age 60 (standard deviation (SD) 4.1) years; mean time post-stroke 62 (SD 33) months) with strok...
PURPOSE Cycling desks as a means to reduce sedentary time in the office has gained interest as excessive sitting has been associated with several health risks. However, the question rises if people will still be as efficient in performing their desk-based office work when combining this with stationary cycling. Therefore, the effect of cycling at 30% Wmax on typing, cognitive performance and br...
Exercise adherence is affected by factors including perceptions of enjoyment, time availability, and intrinsic motivation. Approximately 50% of individuals withdraw from an exercise program within the first 6 mo of initiation, citing lack of time as a main influence. Time efficient exercise such as high intensity interval training (HIIT) may provide an alternative to moderate intensity continuo...
INTRODUCTION The aim of the present study was to investigate the effect of ingesting a glucose plus fructose drink compared with a glucose-only drink (both delivering carbohydrate at a rate of 1.8 g.min(-1)) and a water placebo on endurance performance. METHODS Eight male trained cyclists were recruited (age 32 +/- 7 yr, weight 84.4 +/- 6.9 kg, .VO(2max) 64.7 +/- 3.9 mL.kg(-1).min(-1), Wmax 3...
آنالیز رشد روش با ارزشی در بررسی کمی رشد و نمو و تولید محصولات به شمار می رود. این آزمایش در مزرعه تحقیقاتی دانشکده علوم زراعی دانشگاه علوم کشاورزی و منابع طبیعی گرگان در سال زراعی 88-1387 اجرا گردید. آزمایش با طرح پایه بلوک های کامل تصادفی در چهار تکرار و در دو شرایط دیم و آبی به صورت آزمایش مرکب اجرا شد. در این آزمایش هفت رقم گندم پر کشت و کار و رایج در استان گلستان به نام های شیرودی، تجن، کو...
Costa VP, De-Oliveira FR. Physiological variables to predict performance in cross-country mountain bike races. JEPonline 2008;11(6):14-24. Mountain bike (MTB) is a recent sport derived from cycling with little information about the athletes and races. The aim of this study was to identify the morph-physiological characteristics in Elite MTB athletes and the physiological variables associated in...
Small depth networks arise in a variety of network related applications, often in the form of maximum flow and maximum weighted matching. Recent works have generalized such methods to include costs arising from concave functions. In this paper we give an algorithm that takes a depth D network and strictly increasing concave weight functions of flows on the edges and computes a (1−ǫ)-approximati...
The effects of protein supplementation on cycling performance, skeletal muscle function, and heart rate responses to exercise were examined following intensified (ICT) and reduced-volume training (RVT). Seven cyclists performed consecutive periods of normal training (NT), ICT (10 days; average training duration 220% of NT), and RVT (10 days; training duration 66% of NT). In a crossover design, ...
OBJECTIVE To study the effects of a physical training program on exercise capacity, muscle force, and subjective fatigue levels in patients with mild to moderate forms of osteogenesis imperfecta (OI). STUDY DESIGN Thirty-four children with OI type I or IV were randomly assigned to either a 12-week graded exercise program or care as usual for 3 months. Exercise capacity and muscle force were s...
