-release buckles on either side of the metal-coiled strap. Methods Land Testing Land testing consisted of body composition, strength, ROM, anaerobic capacity, and an aerobic capacity (VO 2 max) test. Body composition was conducted with the COSMED BOD POD (COSMED, Chicago, IL). Strength measures were obtained using

Evaluation of anaerobic energy production is important to athletes involved in speed-endurance sports. The Wingate test is one of the most popular laboratory tests designed to evaluate anaerobic power. 1 This 30-second cycle ergometer test has been shown to be effective at distinguishing

However, it is not clear whether short-term anaerobic performance is also affected during acute hypoxia (simulated altitude). 8 , 9 Elite alpine skiers require both a high level of aerobic and a very high level of anaerobic performance. 9 , 10 A popular method to mitigate the detrimental consequences of

Intense sprint exercise results in rapid increases in energy turnover from both aerobic and anaerobic metabolism. Having an

A definitive measure for assessing the energy contribution of anaerobic pathways during exhaustive exercise remains inconclusive. The accumulated oxygen deficit (AOD) has been used in several studies to estimate energy contribution. The underlying assumptions of the AOD measure have been criticized for underestimating the true contribution of anaerobic metabolism in high intensity exercise. Indeed, the AOD measure has been the subject of much controversy. Several of the physiological exercise responses of children may lead to an even greater underestimation of the anaerobic energy contribution to high intensity exercise in children than adults when AOD measures are calculated.

There is limited data concerning the glycemic changes during mass sporting competitions for children and youth with diabetes. In general, aerobic exercise is associated with decreasing glucose values, whereas brief, very high-intensity or anaerobic exercise is related to increasing glucose values

The main purpose of the present study was to determine isokinetic strength and endurance, isometric strength, and anaerobic power for untrained healthy Saudi children and adolescents. The secondary purpose was to evaluate the effects of age in relation to anthropometric characteristics on strength and anaerobic performances. Forty-four (untrained) 11- to 19-year-old boys were grouped by age: 11-13 years, 14–16 years, and 17–19 years. All participants underwent anthropometric measurements, a flexibility test, a vertical jump test, a grip strength test, isokinetic strength measurements (Cybex Norm), and a Wingate anaerobic power test. Oneway ANOVA results indicated age-related increases in muscle strength and power. High correlation coefficients that were found among age and strength and anaerobic power indices almost disappeared when fat-free mass (FFM) was controlled for, indicating that the amount of variance in these indices that was explained by age is mostly shared by FFM. In addition, stepwise linear regression models indicated that FFM was the main predictor of strength and power performances. Thus, FFM was the best scaling variable for body size when comparing these age groups of Saudis. Until wide-range normal representative values for isokinetic strength and anaerobic power for Saudi children and adolescents are available, the present study’s results can serve as a reference for these indices.
