Related to supramaximal exercise: anaerobic exercise

anaerobic exercise

any short-duration exercise that is powered primarily by metabolic pathways that do not use oxygen. Such pathways produce lactic acid, resulting in metabolic acidosis. Examples of anaerobic exercise include sprinting and heavy weight lifting. Compare aerobic exercise. See also active exercise, passive exercise.

anaerobic exercise

A general term for exercise consisting of slow rhythmic movements against a force—e.g., calisthenics, such as push-ups, sit-ups, weight lifting—which evoke minimal increases in heart rate. Anaerobic exercise is said to strengthen muscles, increase joint mobility and reduce risk of musculoskeletal injury.

an·ae·ro·bic ex·er·cise

(an'ār-ōbik ek'sĕr-sīz)
Physical activity that alternates short bursts of energy with periods of rest.

anaerobic exercise

exercise at an intensity exceeding aerobic capacity, which therefore draws a significant fraction of its energy from anaerobic sources. Sprints of any form, jumps and forceful throws are examples. In sustained anaerobic exercise, metabolic products accumulate rapidly; this is indicated by the continual increase of blood lactate concentration throughout the period of effort, but other products such as phosphate ions, ADP, AMP and adenosine contribute much more to the fatigue which forces termination of the effort after some 10-120 s, depending on its intensity. Also known as supramaximal exercise . Compare aerobic exercise.

anaerobic exercise,

n physical activity, which instigates a metabolism that does not depend on oxygen. Examples include isotonics, in which the muscles contract against an object of resistance with movement (e.g., weight lifting); isometrics, in which muscles contract against resistance but without movement; and calisthenics (e.g., sit-ups and knee-bends), which increase flexibility and improve joint mobility.

anaerobic

the absence of air.

anaerobic bacteria
anaerobic effluent treatment
is usually conducted in deep ponds where air does not penetrate. A fully contained system is also available.
anaerobic exercise
exercise at high work intensity during which the needs of muscle metabolism for oxygen exceeds the capacity of the circulation to supply it and an oxygen debt is incurred.
anaerobic infection
one caused by aerobic organisms.

From the results and discussion of these previous studies, we hypothesized that acute hypoxia would cause a greater degree of peripheral muscle deoxygenation during supramaximal exercise when compared with performance under normoxia, whereas performance during the exercise would be maintained by an increment in anaerobic energy production.
These factors lead us to the hypothesis that athletes would experience a greater degree of muscle deoxygenation during supramaximal exercise under hypoxia when compared with untrained subjects.
The present study was designed to investigate the effects of acute normobaric hypoxia on peripheral muscle deoxygenation during the supramaximal exercise in trained track sprinters and healthy untrained non-athletes.
It follows from the present study and previous reports that acute hypoxia would enhance the degree of peripheral muscle deoxygenation during supramaximal exercise compared with normoxia.
These findings suggest that arterial oxygen desaturation caused by pulmonary diffusion limitation would be the dominant factor to explain a pronounced muscle deoxygenation during supramaximal exercise under hypoxic conditions.
There are no reports, as far as we know, to compare the effects of hypoxia on muscle oxygenation trends during supramaximal exercise between athletes and untrained subjects.
Our findings are consistent with earlier results, suggesting that pronounced muscle deoxygenation during supramaximal exercise under hypoxia in athletes would be explained mainly by the greater arterial oxygen desaturation.
It may be difficult to determine the effect of hypoxia on lactate kinetics during and following supramaximal exercise using capillary blood samples.
To the best of our knowledge, no study has assessed the effects of long duration intermittent fasting (Ramadan Fasting) on removal rate of LA from the blood following supramaximal exercise.
