The answer is true
Endurance training can improve athletic ability, and improve sustainability over long periods of time. (Aerobic workouts involve oxygen, necessary in many physical activities).
Chronic stress, or a constant stress experienced over a prolonged period of time, can contribute to long-term problems for heart and blood vessels. The consistent and ongoing increase in heart rate, and the elevated levels of stress hormones and of blood pressure, can take a toll on the body. i hope this helps <3
