anaerobic capacity

an·aer·o·bic ca·pa·ci·ty

(an'ār-ō'bik kă-pas'i-tē)
Maximal work performed during maximum-intensity short-term physical effort; reflects the energy output capacity of anaerobic glycolysis.

anaerobic capacity

the total amount of energy that can be obtained from anaerobic sources (creatine phosphate breakdown and anaerobic glycolysis) in a single bout of continuous exercise. Strictly a theoretical concept, since some contribution from aerobic metabolism cannot be prevented in any real-time measurement. Estimated by total work output in 30 s (Wingate test) or 90 s cycle ergometer tests, or by treadmill running up a steep gradient; the longer test periods more closely extract all possible energy from the anaerobic systems, but cannot avoid a small yet significant aerobic contribution.

Thus far, the literature base on CF demonstrates its efficacy for improving body composition (15,42,48,51,52), aerobic and anaerobic capacity (42,51,57), muscular strength (40,56), flexibility (15,57), and extremity power (6,40).
2]-plateau is a function of the finite anaerobic capacity and the ability to regulate anaerobic substrate metabolism and the concomitant recruitment of less metabolically efficient type II muscle fibres.
The Wingate test provides basic parameters of anaerobic performance: anaerobic power (AP) is the maximal value one achieves in the first few seconds of the test and represents the phosphocreatine energetic pathway of power development; the mean power is a unit of anaerobic capacity (AC) that includes glycolytic energy release as well; the explosive power (EP) is the speed at which maximal power is achieved and reflects transformation of chemical energy into mechanical work.
Since it is known that the fatigue index indicates the rate at which power output declines for an athlete, [35] this index can provide coaches with information about an athlete's anaerobic capacity or endurance.
The requirements in aerobic and anaerobic capacity were differences between distance (Borysiuk, et al.
Izumi Tabata found that this form of training not only increases aerobic capacity, or stamina, but also improves anaerobic capacity, or ability to build muscle.
To the estimation of the anaerobic capacity the run anaerobic speed test (RAST) and 20-m dash test were performed on different days, with at least 24 hours between each test.
The 30-second WAnT (11) was performed on the Monark ergometer (Monark AB, Varberg, Sweden) with peak power, anaerobic capacity (AC), and fatigue index (FI) (%) being calculated and recorded.
After six weeks of testing, the group following Tabata's plan - exercising for just 88 minutes a week - had increased their anaerobic capacity by 28 percent and their VO2 max, a key indicator of cardiovascular health and maximal aerobic power, by 15 percent.
During exercise they maintained higher muscular strength and aerobic power throughout, As the exercise progresses, anaerobic work capacity tends to be higher [22], so that the general physiological profile of the successful pahalwan is of one with high anaerobic power, high anaerobic capacity, high muscular endurance, average to above average aerobic power and normal flexibility [23].
They also discuss quality assurance in the exercise laboratory, athlete preparation prior to testing, and generalized test procedures for the determination of anaerobic capacity, concepts for the measurement of maximal aerobic power and blood lactate thresholds, and guidelines for the use of altitude and hypoxic exposure and the preparation of athletes for hot and humid environments.
