The purpose of this study is to determine if a heart rate-speed index can assess training adaptations or determine how an athlete is responding to their training over 16 weeks of swimming training.

Previously it has been used as a valid measure in runners. It uses the relationship between heart rate and speed to determine how an athlete is responding to exercise. It is based off the well-known phenomenon; as an athlete adapts their heart rate will decrease for the same intensity.
