![]() ![]() To make matters even more confusing, some coaches also refer to Cycle Rates (CR), rather than SR, which makes the fly, back, breast and free rates similar. For example, a 1 second CT is the same as a 120 SR. The CT is often referred to as SR but it is not. Some coaches prefer to use Cycle Time (CT), which is the time it takes a hand to go from one entry to the next one, or through one cycle. When it comes to measuring SR, there is a lot of confusion. The ideal SR for a given swimmer depends on many variables, including the event distance, stroke, stroke technique, age, size, kicking speed and physical maturity of a swimmer. In breaststroke and butterfly, since both arms are pulling at the same time, the SR’s are about half of those of freestyle and backstroke. ![]() The SR of a swimmer is equivalent to the RPM of an engine that is how many arm strokes are taken per minute. The greater the propulsion and the lower the frontal drag forces, the further the swimmer will go with each stroke taken. A swimmer’s DPS is determined by the propulsion and the frontal drag forces. The truth is that in order to swim fast, a swimmer needs to achieve the ideal DPS and SR. It seems as if SR has lost some of the attention it deserves. They both count equally in determining the swimmer’s speed, yet many coaches place a lot more emphasis on DPS than they do on SR. The velocity of a swimmer in any stroke is determine by the swimmer’s stroke rate (SR) multiplied by the swimmer’s distance per stroke (SR x DPS). ![]()
