Hard calf muscles do not mean that you can’t grow taller. Patients with symptoms of hard calf muscles, may be due to long-term strenuous exercise such as running, playing soccer, etc. or overwork such as heavy manual labor and other reasons. Hard calf muscles do not affect the growth and development of bones, and there is no correlation with the human body’s height, so hard calf muscles are not a manifestation of the human body can not grow taller. Whether the human body’s height can grow or not, mainly depends on whether the epiphysis of the long bone is closed or not. If the epiphysis is not closed, there is still the possibility of growing taller, if the epiphysis is closed, the possibility of growing taller is not great. At the same time, it is also related to genetic inheritance, nutritional status, exercise status, sleep quality and other factors. If there is any discomfort, it is recommended to consult a doctor in time.
