Is There Swimming Testing?
Swimming testing includes several specific methods adapted to assess an athlete's performance in the water. Unlike running tests, swimming tests must take into account technique, hydrodynamics, and different swimming strokes.
Critical Speed (CSS)
Measures the maximum speed a swimmer can maintain for a long time without significant fatigue. Test: 400m and 50m/100m at maximum speed.
SWOLF Index
A measure of swimming efficiency: SWOLF = time (sec.) + number of strokes in a 50m pool. A lower SWOLF means better efficiency.
Lactate Threshold
Blood lactate measurement after swims of varying intensity. Determines the aerobic/anaerobic threshold.
STEP Test
7×200m at increasing speed. Heart rate and lactate are measured after each segment.
