The statement is true as both systems, muscular and cardiovascular, can be overloaded during exercise.
Further Explanation:
Overload is defined as when the body is adapted to a certain level and amount of exercise, progressive increase of the exercise load is required for any further improvement. This is known as progressive overloading.
The cardiovascular system can be overloaded in two ways. First is by <u>pressure overload where peripheral resistance is increased in the circulatory system.</u> To overcome this resistance, the heart has to pump harder and it leads to high blood pressure and hypertension. The second way of overloading cardiovascular system is by exercise, the volume overload method. In this, larger volume of blood is pumped than normal which overloads the cardiac muscle. This can be attained by doing exercises that involve large muscle groups for prolonged time periods, especially in continuous activities. Some of these exercises include jogging, walking, dancing, and cycling.
While doing exercise, the muscular system can also be overloaded either mechanically or metabolically. For example, resistance exercises can lead to overload of muscular system resulting in leaner muscles.
Both the systems can be overloaded while exercising by changing variables like intensity, duration, or frequency of exercise. This will result in an improvement of cardiovascular system and muscular system of the body.
