3. each participant is warmed up sufficiently to reduce the risk of injury;

4. the participants tested the following support angles, respectively: 35 °, 40 °,42 °, 45 ° and 50 °;

5. during the test, the participants rowed for at least 5 minutes under the corresponding supporting angles, and the data of the speed, the heart rate, the rowing power and the like of the participants are recorded during the test;

6. after the test is finished, the participants fill out questionnaires and evaluate the comfort, fatigue degree and sensory efficiency under the supporting angle;

7. after all tests are completed, the data are analyzed to obtain the optimal supporting angle.

The experimental data obtained finally are as follows:

table 1: different pedal support angle contrast experiments:

according to the above data, the 42 degree support angle performs better in terms of average speed, heart rate, power, comfort, effort and efficiency feel. The following is an analysis of experimental data:

1. average speed: the average speed at the 42 degree support angle is highest (4.7 m/s), indicating that at this angle the participant is able to transfer force more effectively to the rowing machine, thereby increasing speed.

2. Average heart rate: the average heart rate at the 42 degree support angle was lower (145 beats/min), indicating that at this angle the participants were less burdened with the heart when the same task was completed.

3. Average power: the average power at the 42 degree support angle is highest (240 watts), indicating that at this angle the participant is able to produce a higher power output.

4. Comfort score: the highest comfort score (8.5/10) at the 42 degree support angle indicates that the participant is more comfortable at this angle.

5. Fatigue degree scoring: the lowest fatigue score (5.5/10) at the 42 degree support angle indicates that the participant experienced less fatigue during exercise at this angle.

6. Efficiency sensation score: the highest perceived efficiency score (8.5/10) at the 42 degree support angle indicates that at this angle the participant believes himself is most efficient during exercise.

In summary, the 42-degree support angle performs best in this experiment, and can provide the rower with the best comfort and efficiency.
