Correct riding method: < /p>
1. Saddle angle and height
The angle of the seat cushion should be kept roughly horizontal during riding; the height of the saddle should be adjusted too high, and the legs will stretch out when the pedal is pressed to the bottom. If the seat is too straight, the tension on the knee joint will be too great; if the seat is set too low, the knee joint will bend very tightly when the pedal is at the highest position, and the pressure on the knee joint will increase. Both of these conditions will cause knee joint tension. damage.
2. The angle of the sole of the foot
When many people ride a bicycle, the sole of their foot will involuntarily become inward or outward, which will affect the ankle joint during the pedaling process. The normal motion trajectory of the knee joint causes unnatural friction and force on the joint. Over time, the knee joint or ankle joint will experience varying degrees of discomfort. The correct riding posture is that the pedaling action is completely maintained on a vertical plane.
3. Pedaling frequency and intensity
Pedaling hard when going uphill, or suddenly accelerating, may cause damage to the knee joint, causing pain and discomfort. Therefore, it is not recommended to pedal hard deliberately and use the natural drop of body weight to exert force.
Professional cyclists will use "high cadence and low force" to protect their knee joints when riding. In a windless environment on a flat road, riding at a cadence of 90 rpm can achieve the highest riding efficiency, while riding at a cadence of less than 70 rpm is self-destructive to the knees. Of course, people who suffer serious knee joint injuries are mainly those who ride for a long time.
