purpose this study was designed to assess the effects of ramadan fasting on the profile of mood state and perceived exertion in young soccer players and aerobic and anaerobic performances during the yo-yo, repeated sprint ability (rsa) and the wingate tests. methods twenty junior male soccer players completed the yo-yo, the rsa, and the wingate tests on three different occasions: one-week befor...

Carbohydrate (CHO) consumption before anaerobic exercise was studied in 13 adolescent boys (15.2 ± 0.9 yrs). A within subjects design was employed where subjects consumed a 22% CHO or volume-matched placebo (PL) beverage 30-min before anaerobic exercise on two separate days. Exercise consisted of a Wingate Anaerobic Test (WAnT), ten by 10-s-sprints, and a second WAnT. Fatigue index and peak pow...

Arginine supplementation has been shown to induce endothelium-dependent vasodilation and enhance exercise performance via increasing nitric oxide (NO) production in patients with various cardiovascular diseases. The purpose of this study was to determine the effect of short-term arginine supplementation on vasodilation and performance in intermittent anaerobic exercise in well-trained male athl...

The objective of the present study was to determine the effects of exercise continued until the anaerobic threshold on balance performance in basketball players. Twelve male basketball players (age = 20.92 ± 2.81 years, body height = 192.72 ± 7.61 cm, body mass = 88.09 ± 8.41 kg, training experience = 7.17 ± 3.10 years) volunteered to participate in this study. A Kinesthetic Ability Trainer (KA...

although sport-physiologists have repeatedly analyzed respiratory gases through exercise, it is relatively new in the cardiovascular field and is obviously more acceptable than standard exercise test, which gives only information about the existence or absence of cardiovascular diseases (cvds). through the new method of exercise test, parameters including aerobic and anaerobic are checked and m...

PURPOSE This study examined the effects of hypohydration and moderate hyperthermia (core temperature elevation) on anaerobic exercise performance in a temperate environment. METHODS Eight active males completed two passive heat exposure trials (180 min, 45 degrees C, 50% rh) with (EUH) and without (HYP) fluid replacement. A single 15-s Wingate anaerobic test (WAnT) was used to assess anaerobi...

Purpose: Ischemic preconditioning (IPC) has been used to protect myocardial cells against ischemiareperfusion injury and is recently utilized for improving exercise performance. It is unknown whether remote IPC (RIPC) to tissues not involved in exercise can induce similar exercise improvements and what “dose” of IPC is necessary to induce exercise performance benefits. This study determined if ...

The anaerobic threshold is commonly measured by either blood lactate (lactate threshold) or ventilatory gases (ventilatory threshold); however, the relationship between these 2 methods is not conclusive. The lactate threshold has been characterised at either a fixed or variable blood lactate concentration (BLa). Recent studies have indicated a specific blood lactate concentration for each indiv...
