Anaerobic exercise in pediatric cystic fibrosis

Pediatric Pulmonology, 2003
AbstractAnaerobic fitness is important for daily functioning of children with cystic fibrosis (CF). The aim of this study was to assess the determinants of anaerobic performance in CF. Anaerobic performance was measured in 39 children with CF (mean age, 13.2 ± 1.8 (SD) years, forced expired volume in 1 sec (FEV1) 81.6 ± 22.1% predicted), using a ...

Anaerobic Exercise and Oxidative Stress: A Review

Canadian Journal of Applied Physiology, 2004
Oxidative stress and subsequent damage to cellular proteins, lipids, and nucleic acids, as well as changes to the glutathione system, are well documented in response to aerobic exercise. However, far less information is available on anaerobic exercise-induced oxidative modifications.

Anaerobic Exercise Testing in Children with Asthma

Journal of Asthma, 1998
Twenty-two males with asthma and 22 healthy males (7-18 years old) performed a Wingate Anaerobic Test. The subjects with asthma had a lower mid-maximal expiratory flow rate (78.3+/-25.3 vs. 100.1+/-24.5%, p < 0.01) than the controls. Aerobic and anaerobic exercise performance (peak power: PP; mean power: MP) were similar for the two groups whether ...

Aerobic exercise, anaerobic exercise and the lactate threshold

British Medical Bulletin, 1992
All exercise draws first on intramuscular stores of ATP and creatine phosphate; initially these are replenished by anaerobic glycolysis. The lactic acid produced contributes to the rapid development of fatigue in high intensity exercise. Aerobic metabolism (at first mainly of glycogen, later increasingly of fat) is the principal route of ATP ...

Aerobic and anaerobic metabolism in exercising dogs

Journal of Applied Physiology, 1964
For an analysis of the energy expenditure as related to the work performance in exercising dogs, the O2 consumption and the lactic acid production were determined at rest and during running on a treadmill at varying speeds (from 4 to 16 km/hr) and inclines (from 0 to +20%).

Anaerobic exercise induces moderate acute phase response

Medicine & Science in Sports & Exercise, 2001
It was intended to compare the immune reaction after single and repeated short bouts of anaerobic exercise.Twelve unspecifically trained male subjects (27 +/- 2 yr, 75 +/- 2 kg, VO(2peak) 52 +/- 2 mL x min(-1) x kg(-1)) performed one 60-s all-out test (SMT) on a cycling ergometer and the same test followed by eight 10-s all-out tests every 5 min (AN-TS)

The effect of preceding anaerobic exercise on aerobic and anaerobic work

European Journal of Applied Physiology and Occupational Physiology, 1983
The effects of exercise-induced elevation of lactic acid concentration in blood [Lab] up to 12-14 mM on the subsequent aerobic (less than or equal to VO2 max) and anaerobic (supramaximal) performance was investigated in a group of trained non-athletic subjects.

Anaerobic exercise in teleost fish

Canadian Journal of Zoology, 1982
In teleost fish, high speed ("burst") swimming is performed anaerobically while sustained performance is aerobic. The degree to which anaerobic energy production contributes to swimming performance in the steady exercise zone (swimming maintained for 2 to 200 min) in unknown.

The Anaerobic Threshold Measurement in Exercise Testing

Clinics in Chest Medicine, 1984
The exercise intensity (VO2) above which aerobic energy production starts to be supplemented by anaerobic mechanisms is termed the anaerobic threshold (AT). Lactic acid is produced at an increased rate above this work level. Since this acid is almost completely buffered by HCO-3, the rate of CO2 production increases in excess of that being derived from

Muscle Deoxygenation in Aerobic and Anaerobic Exercise

1998
It has been generally accepted that the use of oxygen is a major contributor of ATP synthesis in endurance exercise but not in short sprints. In anaerobic exercise, muscle energy is thought to be initially supported by the PCr-ATP system followed by glycolysis, not through mitochondrial oxidative phosphorylation.
