title: [Maximal aerobic capacity and sports activity in Mexicans from 13 to 56].
abstract: The maximum oxygen uptake (VO2máx) of Mexicans living at 2240 m altitude was measured to obtain reference values relating VO2máx with athletic performance, and to evaluate the impact of this measure of cardiorespiratory fitness and sport activity on the ageing process. Clinically healthy male individuals (N = 138), 13 to 56 years of age, were divided into groups by decade and according to sport participation. The VO2máx maximum values for power (Power max), and heart rate (HRmax) were measured while subjects exercised on an electronic cycle ergometer using an open circuit spirometry system. The maximum power index (PImax) was also calculated. The VO2máx indicated that modes of sport activity positively affected aerobic power and "counteracted" age-related decreased in HRmax-, VO2máx-, Powermax-, and PImax.
