Final answer:
Exercise intensity for maintaining adequate cardiorespiratory fitness according to the ISSA and the ACSM should be within 60-70% of your VO2 max. This intensity range supports sustained aerobic activity, contributing to overall health and endurance.
Step-by-step explanation:
According to the ISSA (International Sports Sciences Association) and the ACSM (American College of Sports Medicine), exercise intensity should be at what percentage of your VO2 max in order to maintain an adequate level of cardiorespiratory fitness? The answer is b) 60-70%.
VO2 max is an important measure of aerobic fitness, representing the maximum amount of oxygen a person can utilize during intense exercise. It is used as an indicator of an individual's cardiovascular and respiratory efficiency. To improve and maintain adequate cardiorespiratory fitness, exercising within 60-70% of your VO2 max is recommended. This intensity level supports the aerobic energy-generating process and is sufficiently supported by aerobic metabolism, allowing for activities to be performed for extended periods.
Cycling, brisk walking, and jogging are examples of aerobic exercises that can be done within this intensity range, providing numerous health benefits such as increased cardiovascular endurance, healthy weight management, and cognitive ability improvements.
