oksüdatsioonisuguvõime

Oksüdatsioonisuguvõime, often translated as oxidative capacity, refers to the ability of an organism or a biological system to perform oxidative phosphorylation, the process by which cells generate energy (ATP) by consuming oxygen. This capacity is largely determined by the concentration and efficiency of mitochondria within cells, particularly in tissues with high energy demands like skeletal muscle, heart, and brain.

Higher oxidative capacity means a greater potential for aerobic energy production. This is crucial for endurance activities, as it allows for sustained muscle contraction without rapid fatigue. Factors influencing oxidative capacity include genetics, training status, age, and health conditions. Endurance training, for example, is a well-known stimulus for increasing mitochondrial biogenesis and improving the function of the enzymes involved in oxidative phosphorylation, thereby enhancing oxidative capacity.

Conversely, a lower oxidative capacity can limit an individual's ability to sustain prolonged physical exertion and may be associated with conditions characterized by impaired energy metabolism or increased susceptibility to oxidative stress. Measuring oxidative capacity can involve various physiological tests and biochemical analyses, providing insights into an individual's aerobic fitness and metabolic health.
