Triathlon fewer injuries than those who only use running as part of their exercise routine due to the incorporation of low impact swim and bike training. Triathletes spend many hours training for competitions, like other endurance event participants. There are three components that have been researched to improve endurance sports performance; aerobic capacity, lactate threshold, and economy. Injuries that are incurred from long hours of a single activity are not as common in triathlon as they are in single sport events. The cross-training effect that athletes achieve from training for one sport by doing a second activity applies to triathlon training.
Triathlon equipment Triathlon, USAT and ITU do not specifically disallow snorkels. British Triathlon does not list snorkels as part of the accepted equipment, thus they are disallowed. For safety reasons in open-water events, some federations permit special inflatable flotation devices; though activating the device will usually disqualify the swimmer, it can be used to float if the swimmer experiences difficulty. Because most triathlon swim stages are conducted in open waters (lakes, rivers, or oceans) which are often cold, many early races allowed wetsuits. However, typical wetsuits manufactured for snorkeling or water skiing are not optimal for triathlon, because the sleeves generally restrict
