This document, which was adapted from Rushall, B. S., & Graham, K. S. (1993). Muscular condition tests for swimming. NSWIMMING Coaching Science Bulletin, 2(20), 1-13, contains descriptions of and protocols for tests that can be used by post-pubertal NSW swimmers to assess the performance of important muscle groups. Some tests are in the formative stage of development. In time, their scientific verification will be completed. All have been adjudged, by a panel of sport scientists and appropriately trained coaches, to have considerable face validity for assessing the type of performance each muscle group has in swimming. These tests are not appropriate for swimmers who have yet to enter the adolescent growth spurt. The age at which this occurs is: (a) for girls, between 11 and 13 years, and (b) for boys, between 13 and 15 years. The tests which are recommended are as follows: 1.Front Abdominal Hold. This measures the static muscular endurance of the frontal abdominal muscles. 2.Lumbar Hold. This measures the static muscular endurance of the lower back. 3.Wide-grip chins. This measures the strength potential of the muscles that produce adduction of the upper arm which is very important in all stroking patterns. 4.Horizontal arm hold. This measures the static muscular endurance of the forearms, wrists, and fingers that are needed to hold hand and lower arm positions in stroking patterns. 5.Standing long jump. This is a single assessment of the adequacy of leg "power" which should form a basis for acceptable leg functioning in all swimming strokes. Coaches are cautioned when first implementing these tests. Since they usually involve maximum exertions, they could cause injury if attempted without adequate precaution. The following tests are recommended: Front Abdominal Hold, Lumbar Hold, Wide-grip chins, Horizontal arm hold, Standing long jump.
