Height depends on the innate height gene and the acquired right amount of calcium and vitamin D. After the developmental period, the bones will not continue to develop. The intake of calcium and vitamin D will enhance bone density, prevent fractures and osteoporosis.

So exercise will not affect height, I mean after development (usually after adulthood)

If teenagers do intensive strength training for a long time, such as weight-bearing squats and hard pulling. Without stretching and relaxing the corresponding muscles in time, the excessively tense muscles may affect the bone development. Moreover, muscle repair and growth after training need a lot of nutrients such as protein and carbohydrates, which will also affect development.

Of course, it is also beneficial for teenagers to do some aerobic exercise occasionally, such as running, swimming and climbing mountains.

Strength training is also called anaerobic exercise.

The classification of anaerobic exercise comes from the classification of skeletal muscle metabolism during human exercise. At present, the concept of anaerobic exercise is mainly based on anaerobic metabolic energy supply system. For example, anaerobic exercise refers to the exercise of human muscles under anaerobic energy metabolism. But what we think of as anaerobic exercise in our daily life refers to the high-speed and strenuous exercise of muscles in the state of "hypoxia". Anaerobic exercise is mostly exercise with high load intensity and strong immediacy, which is difficult to last and the time of fatigue elimination is slow.

Anaerobic exercise is relative to aerobic exercise. The metabolism of the body is accelerated during exercise, and the accelerated metabolism needs to consume more energy. The energy of human body comes from the catabolism of sugar, protein and fat. When there is not much exercise, such as jogging and dancing, the energy supply of the body mainly comes from the aerobic metabolism of sugar. The exercise that mainly depends on the aerobic metabolism of sugar is what we call aerobic exercise. When the sports we are engaged in are very intense or explosive, such as weightlifting, 100-meter sprint, wrestling and so on. At this time, the body needs a lot of energy instantly, but under normal circumstances, aerobic metabolism can't meet the needs of the body at this time, so sugar quickly produces a lot of energy through anaerobic metabolism. Exercise in this state is anaerobic exercise.
