Jessica, a 26-year-old client weighing 125 lb (56.8 kg), completes the 1-mile walk in 16:40 with an immediate post-exercise HR of 132 bpm. Calculate her V• V•
O2 O2 max:
max = 132.853 – (0.1692 x body weight) – (0.388 x age) – (3.265 x time) – (0.1565 x HR) = 132.853 – (0.1692 x 56.8) – (0.3877 x 26) – (3.265 x 16.67) – (0.1565 x 132) = 132.853 – 9.61 – 10.08 – 54.43 – 20.66 = 38.07 mL/kg/min
1.5-mile Run Test
The 1.5-mile (2.4-km) run test is used by the U.S. Navy to evaluate cardiovascular fitness levels of its personnel. The purpose of this test is to measure cardiovascular endurance and muscular endurance of the legs. Like the Rockport 1-mile (1.6-km) fitness walking test, the goal of this test is to cover the required distance in the least amount of time. A running track is the preferred setting. Due to the intense nature of running, this test is not suitable for less-conditioned individuals. Effective pacing is important for a successful outcome. Equipment: • Quarter-mile track or suitable alternative (e.g., treadmill) • Stopwatch • HR monitor with chest strap (optional) Pre-test procedure: • After explaining the purpose of the 1.5-mile (2.4-km) run test, define the course. • The goal of the test is to run as fast as possible for 1.5-miles (2.4-km). Walking is permitted if necessary, though it will create an underestimation of the V•
