Incremental Testing Design on Slide Board for Speed Skaters: Comparison Between Two Different Protocols.

abstract：:The 5-repetition sit-to-stand test (FRSTST) is a widely used measure of functional strength, particularly among older adults. The purpose of this review was to summarize the findings of research using the intraclass correlation coefficient (ICC) to describe the test-retest reliability of the FRSTST. A search of 3 elec...
