-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

In addition, the high occurrence of high-intensity efforts such as dynamic body contacts and swimming sprints 3 , 4 implies that in addition to aerobic, anaerobic metabolism appears to play a decisive role in energy

adaptations across all three energy systems, resulting in faster rates of phosphocreatine breakdown and greater glycolytic and mitochondrial enzyme activity ( Ross & Leveritt, 2001 ). 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
