Stroke rate (sport)

The number of strokes (also stroke frequency ) is a measure of the number of movement cycles per minute in canoeing and rowing . For Canadians this corresponds to the number of paddle strokes , for rowing boats the number of oar strokes . For kayaks with double paddles , only the stroke on one side is counted. H. when the paddle is used alternately, the number of complete cycles is counted and not the (twice as high) number of paddles used.

The number of strokes is generally relatively high at the beginning of the race, then changes to the low-frequency track stroke and increases again towards the end of the race towards the final sprint . The number of beats is measured in beats per minute .

To measure the number of beats, there are special number of beats that automatically calculate and display the number of beats from the period for executing a certain number of cycles (typically three).

In canoe racing , the number of strokes in a single kayak (K1) is between 70 and 75 in GA1 , between 80 and 85 in GA2. On sprint routes up to 200 m and on the final sprint, the number of strokes can be up to 130. In team boats, the number of beats is generally 5 to 10 beats per minute higher than in the K1.

In rowing , the number of strokes during a 500 m race is between 32 and 38, with the Olympic 2000 m distance around 30 to 35.
