Participants: Fifty boys (24 obese and 26 control), aged 11 to 15 years, with no history of asthma or other atopic diseases, took part in the study. Measures: Anthropometric measurements and spirometry were performed at rest and spirometry was repeated at 5 and 15 minutes after an eight-minute submaximal exercise on cycle ergometer. Results: The falls in ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) and expiratory rates at 5 and 15 minutes after the exercise were significant in obese boys. Only significant change was the fall in FEV1/FVC at 5th minutes in controls. There was no significant difference between obese group and controls in the number of EIB-positive cases. Pulmonary function changes after the exercise had significant negative correlation with body mass index, subscapular and biceps skinfolds. Conclusions: Since the fall in pulmonary function was severe in obese boys and these falls were correlated with body mass index and skinfolds, it is concluded that diagnosis and management of EIB may improve aerobic exercise performance and participation in obese children.

Spirometry was performed before and every three minutes after a seven-minute exercise challenge on a treadmill. There were 11 obese children and 6 controls who had at least a 15% fall in at least one of three monitored pulmonary function parameters ( P<.05). The group mean percentage falls in FEV1and FEF25%-75%were significantly greater in the obese group than in the controls. The pattern of bronchospasm, occurring soon after the exercise challenge, is consistent with that found in the known asthmatic population. A significant correlation was found between triceps skin-fold thickness and degree of fall in FEF25%-75%( r= .55, P<.005). This study demonstrated that significantly greater frequency and degree of bronchospasm of the smaller airways occur in obese children, partially related to the amount of subcutane...

This randomized, double blind, crossover study was composed of two 8-week periods of supplementation with either 100 mg.day(-1) CoQ10 or placebo. Fifteen healthy and sedentary men participated in the study. Five Wingate tests with 2 min rest between tests were performed. Blood samples were collected at rest, immediately after, 15 and 60 min after the fifth Wingate test for oxidative stress (malondialdehyde, nitric oxide, xanthine oxidase and adenosine deaminase) and antioxidant (superoxide dismutase, glutathione peroxidase and uric acid) markers. At baseline exercise session, malondialdehyde increased 15 and 60 min after the exercise compared to the rest and immediately after the exercise. Malondialdehyde at rest, immediately after and 60 min after the exercise decreased with coenzyme Q10 supplementation when compared to baseline. At baseline exercise session, uric acid increased 15 and 60 min after the exercise when compared to the rest. In conclusion, lipid peroxidation and antioxidant defense increase after repeated short-term supramaximal exercise. Coenzyme Q10 supplementation partially prevents the increase in lipid peroxidation after repeated short-term supramaximal exercise.

Methods: Twenty-three untrained young males participated in the study. A double blind design was used to create the creatine and placebo groups. Wingate test was performed 5 times with 90 g x kg(-1) body weight load with 2-min intervals. Peak power, mean power (MP), fatigue index (FI) were calculated. Capillary blood samples for lactate analysis were taken during the initial rest period and soon after the fifth Wingate test. For 6 days the creatine group (n=12) ingested 5 g creatine monohydrate, the placebo group (n=11) a flavored drink without creatine monohydrate 4 times daily. On the 7th day, the Wingate tests were repeated, as was the 1st day. Results: In the creatine group, MP in the 3rd and 4th Wingate test, in the placebo group FI in the 1st and 2nd Wingate test significantly increased. While the total power output obtained from the five Wingate tests increased 7.6% from 366.3+/-65 W to 394+/-67.1 W, there was no change in the placebo group. Conclusions: It is concluded that creatine supplementation enhances total power output during the repeated bouts of supramaximal exercise separated by short resting intervals.

Fourteen healthy males participated in this study. The subjects&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; individual preferred walk-to-run transition speeds (WRTS) were determined. Each subject covered a 1.5-mile distance for 4 exercise tests; walking (WRTS-W) and running (WRTS-R) tests at WRTS, 2 kmxh-1 slower walking than WRTS (WRTS-2) and 2 kmxh-1 faster running than WRTS (WRTS+2). Blood samples were taken pre, immediately, and 30 minutes post each test. The changes in (MDA) and glutathione (GSH) levels and superoxide dismutase (SOD), catalase (CAT), and creatine kinase activities were measured. Oxygen uptake, carbon dioxide output, oxygen uptake per kilogram of body weight, and heart rate during exercises were significantly higher in both the WRTS-W and the WRTS+2 exercises compared with the WRTS-2 and WRTS-R. Oxygen consumption and energy expenditure were higher in walking than in the running exercise at the preferred WRTS and only WRTS-W exercise significantly increased MDA levels. Catalase activities were increased by WRTS-W, WRTS-R, and WRTS+2 exercises. Changes in SOD and CAT activities were not different between walking and running exercises at the preferred WRTS. Total plasma GSH increased in response to WRTS-W exercise, which could be associated with an increase in MDA. Also, total GSH levels 30 minutes postexercise were significantly lower than postexercise in WRTS-2, WRTS-W, and WRTS+2 exercises. Our results indicate that walking and running exercises at the preferred WRTS have different oxidative stress and antioxidant responses.
