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.
