The 30 Second Sit to Stand Test is also known as 30 Second Chair Stand Test (30CST), was initially designed for testing leg strength and endurance in older adults. It is part of the Fullerton Functional Fitness Test Battery. This test was developed to overcome the floor effect of the five or ten repetition sit to stand test in older adults.[1] There is also some consideration for its use as a physical performance test in younger adult and athletic populations, but further investigation may be necessary.
