Interaction of Cardiorespiratory Physical Fitness and Heat Tolerance,
Abstract
Most authors agree that physical training in a cool environment improves tolerance to work in the heat and heat acclimatization but the extent or degree of improvement remains controversial. The major benefits of physical training appear to involve exposure durations (heat) of less than two hours. The best improvement in heat tolerance is associated with intensive interval or continuous training at a training intensity greater than 50% of the maximal oxygen uptake for 8 to 12 weeks; the maximal oxygen uptake should be increased 15-20%. Generally, individuals with high maximal oxygen uptake values (previously trained and endurance athletes) are at an advantage in the heat. Utilization of proper physical training appears to produce about 50% of the total adjustment resulting from heat acclimatization, while increased fitness is associated with greater retention of acclimatization in cool environments.
