OBJECTIVE To compare the aerobic and anaerobic exercise capacity of children with juvenile idiopathic arthritis (JIA) with healthy controls, to determine if there were differences based on disease onset type, and to examine the relationship between aerobic and anaerobic exercise capacity in children with JIA. METHODS Sixty-two patients with JIA (mean +/- SD age 11.9 +/- 2.2 years, range 6.7-1...

sleep deprivation has negative effects on performance and resulted in elevating of mortality risk, cardiovascular disease and diabetes. the purpose of this study was to investigate the effects of 30 hour sleep deprivation on serum levels of c-reactive protein, blood lactate, muscular strength and physiological factors of rast test in active students. the present study was a semi-experimental on...

gums are the most important stabilizers that are used in ice cream and other frozen dairy dessert industries. in this study, effect of different levels of guar gum (0, 0.1, 0.2 and 0.3%) and arabic gum (0, 0.1, 0.3 and 0.5%) on rheological behavior of frozen yogurt was investigated. the rheological behavior of samples showed that all samples exhibit shear thinning behavior and power law model f...

purpose this study investigated the effects of time-of-day on aerobic and anaerobic performances during the yo-yo, repeated sprint ability (rsa) and the wingate tests in young soccer players. methods in a counterbalanced and a random order, twenty junior male soccer players completed the yo-yo, the rsa, and the wingate tests at two different times-of-day: 07:00 and 17:00 h. during the yo-yo tes...

Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...

The physiological adaptation to training is specific to the muscle activity, dominant energy system involved, muscle groups trained, as well as intensity and volume of training. Despite increasing popularity of snowboarding only little scientific data is available on the physiological characteristics of female and male competitive snowboarders. Therefore, the purpose of this study was to compar...

INTRODUCTION Taekwondo (TKD) is a combat sport, which has also been proposed as a fitness program, with a strong anaerobic component. Creatine (Cr) supplementation is used to improve both anaerobic exercise performance and body composition. Therefore, Cr supplementation could be beneficial in TKD. AIMS To determine the effect of Cr supplementation (50 mg/kg body wt) on body composition, anaer...
