Effect of reduced training volume on cardiac function, VO2 max, and running performance.
This study examined the physiological effects of reducing training mileage in a veteran long distance runner while increasing exercise intensity. Variables measured included stroke volume, cardiac output, maximum oxygen uptake, ventilation threshold and performance time in a 10,000 m run. For 8 weeks, training mileage was reduced from 75.8 miles per week to 42.5 miles per week including interval training twice weekly. Following the specialized training, performance time was 10 seconds faster although VO2max and heart contractility had decreased. It was concluded that distance running performance can be maintained while considerably reducing training mileage and increasing exercise intensity twice a week.
