Repetition Increases Efficiency

Training is specific, so the more you practice your sport, the better you are able to do it. That’s why triathletes who compete and train in three sports are relatively mediocre in each sport when compared to those who only run, cycle or swim. (Sports Biomechanics, Volume 6, Issue 1, 2007).

In this study, elite cyclists produced significantly more effective force on their pedals than triathletes. They had far less wasted side-to-side motion, and they required less oxygen to do the same amount of work.

Repeating the same motion over and over causes your muscles to become more efficient so they can generate more power with less oxygen. For example, when you run, you use your arms to maintain your center of gravity. When your right leg moves forward, so does your left arm; your left leg and right arm move backward.

Do triathletes get injured more often than one-sport athletes?

Triathletes are injured only about one third as often as marathon runners even though they do far more work in their program of swimming, cycling and running. Training intelligently for three sports is less likely to injure you than training very hard for one. Training is limited by damage to skeletal muscles.

Every time you exercise, your muscles develop small tears with bleeding. It takes at least 48 hours for muscles to heal from exercise. Each sport stresses a particular group of muscles most. Marathon runners who train every day stress the same muscles and often do not allow adequate time to recover from the previous day’s workout, so they are at increased risk for injury.

Top triathletes train in different sports on consecutive days. Running stresses the lower leg muscles most, cycling stresses the upper leg muscles most and swimming stresses the arms and shoulders most. Triathletes usually set up a workout schedule that includes two sports on one day and one on the next.
