Land/Water Strength In Swimmers
Strength is an essential physical quality for swimmers in short distances. Sprinters are typically stronger than distance swimmers. They spend more time developing strength on land. This is because sprinters need more strength to swim faster for short distances. Sometimes they spend about 40% of workout time on dryland. Is it enough or too much? Testing of swimmers with tensiometers in land/water strength helps answer these questions.

Tensiometers Testing Methodology
Land/water strength is carried out using tensiometers. Strength is measured in four positions: on dryland in the middle of stroke, in water performing pulling, kicking and full body swimming. On dryland, with the use of tensiometers, the athlete applies a maximum effort during an isometric contraction on a swim bench, while in the water the athlete aims to stretch the maximum length of a rubber cord with all-out efforts during the pull, kick, and swim.
