Effects of Caffeine on Anaerobic Exercise in Boys

Pediatric Exercise Science, 2012
The effects of caffeine on anaerobic exercise in young boys was investigated. Twenty-four healthy 8–10 year old boys participated in a randomized doubleblind, double-crossover, counter-balanced study. Each subject received the caffeinated drink (CAF—5 mg · kg−1) or placebo (PL) twice each on four separate visits.

Creatine Is an Ergogen for Anaerobic Exercise

Nutrition Reviews, 2009
Throughout history, athletes have searched for performance-enhancing agents. Recently, creatine (N-[aminoiminomethyl]-N-methyl glycine) has been marketed as an ergogenic dietary supplement. There appears to be scientific merit to the claim that creatine is ergogenic when taken in large amounts.

Reproducibility of Post-Exercise Lactate and Anaerobic Threshold

International Journal of Sports Medicine, 1988
To test the effect of previous strenuous training on lactate (LA) formation and on changes of lactate threshold (AT) values, a group of seven male athletes aged 26.3 +/- 9.2 years, height 184 +/- 6.2 cm, body weight 79.3 +/- 8.1 kg, percentage of body fat 8.8 +/- 3.7 and VO2 max 56.2 +/- 5.4 ml/kg were examined on a treadmill to the maximum in the ...

High anaerobic energy release during submaximal arm exercise

Clinical Physiology, 1993
Summary. The anaerobic energy release during submaximal arm (AE) and leg exercise (LE) has been estimated from O2 deficit measured at the onset of exercise. Eight male subjects were studied during 8–10 min of arm or leg cycling at the same relative workload (53% of the peak exercise‐induced increase in pulmonary oxygen uptake, VO2). The workloads were

Anaerobic metabolism of the respiratory muscles during exercise

Medicine & Science in Sports & Exercise, 1984
Although minute ventilation (VE) exhibits marked increases during heavy rhythmic exercise utilizing a large muscle mass, the extent to which this hyperpnea stresses the respiratory muscles remains controversial. In an attempt to resolve this matter, we measured arterial blood lactate concentration during seated isocapnic reproduction of peak exercise ...

Plasma Volume Responses to Consecutive Anaerobic Exercise Tests

International Journal of Sports Medicine, 1996
This study examined the change in plasma volume (% delta PV) in response to consecutive Wingate tests (30 sec Anaerobic Power test). Twelve active men (21 +/- 1.6 yr, 81.3 +/- 6.6 kg) performed two Wingate tests (W1 and W2, separated by 10 min) on three occasions (T1-T3, tests were two weeks apart).

Massive Insulin Secretion in Response to Anaerobic Exercise in Exercise-induced Hyperinsulinism

Hormone and Metabolic Research, 2005
Exercise-induced hyperinsulinism (EIHI) is a recently described entity characterised by recurrent episodes of hypoglycaemia induced by physical exercise. The index patient for this disorder and a matched control were subjected to aerobic and anaerobic exercise tests on a cycle ergometer.

Quantification of anaerobic energy production during intense exercise

Medicine &amp Science in Sports &amp Exercise, 1998
Anaerobic energy production during supramaximal exercise has been estimated from muscle metabolic changes. Based on such measurements the anaerobic energy production was determined to be 63 and 189 mmol ATP x kg(-1) d.w. for 60 and 142 s of exhaustive cycling exercise, respectively. These estimations do not, however, include release of lactate from the

Oxidative metabolism and anaerobic glycolysis during repeated exercise

Journal of Physiology and Biochemistry, 1998
The purpose of the present study was to examine aerobic and muscle anaerobic energy production during supramaximal repeated exercise. Eight subjects performed three 2-min bouts of cycling (EX1-EX3) at an intensity corresponding to about 125 % of VO2 max separated by 15 min of rest.
