The main symptom of this injury is pain. If the shoulder hurts, the pain in this part is mainly caused by the long tube and low handlebar on the car; Neck pain, this phenomenon often occurs at the same time as shoulder pain; The third is low back pain, which is often caused by straightness when riding, because more strength will increase the burden on the waist and lead to waist fatigue.
2. Upper limb injury

The harm of running
1, acute renal failure
Excessive exercise leads to muscle dissolution, and myoglobin in muscle will form crystals in renal tubules, blocking renal tubules, thus affecting the normal operation of kidneys.
2, anemia.
In fact, excessive exercise can also lead to anemia. Anemia here does not mean that the body bleeds a lot, but is called "sports anemia" in medicine. This is because a lot of sweat will flow out of the body during exercise. Besides water, there are many metal ions in sweat, such as iron ions in blood. The loss of sweat will lead to the reduction of iron ions in the blood and anemia, so it is also called "iron deficiency anemia".
3, affect endocrine
When you have experienced a heavy exercise, you often feel very tired and don't want to move, let alone continue to exercise. In fact, this phenomenon is caused by endocrine inhibition.
Usually, it is the pituitary gland that controls the secretion of hormones in our body. When we exercise excessively, the function of pituitary gland will be inhibited, which will affect the secretion of hormones, thus leading to physical fatigue, poor physical recovery and even cramps.
