Validity of the 3 min step test in moderate altitude: environmental temperature as a confounder

摘要: The 3 min step test is a widely used method to evaluate physical fitness, but whether this valid when performed at altitude unknown. purpose of study was examine the effect on fitness score test, and role ambient temperature in effect. In I, 11 healthy volunteers (aged 18.1 ± 1.1 years) sea level (1950 m). Plasma lactate stress hormones, as indicators metabolic stress, were measured before after test. To determine temperature, we II with same simulating condition (24 °C high versus 32 °C level) 23 subjects 20.4 ± 0.4 y). plasma elevated during greater extent altitude. cortisol testosterone levels only However, heart rate (HR...
