How much cardiorespiratory endurance is enough?



According to guidelines from the U.S. Department of Health and Human Services (HHS), for general health adults should aim for 150 to 300 minutes of moderate physical activity or 75 to 150 minutes of vigorous-intensity aerobic physical activity each week


Final answer:

Cardiorespiratory endurance requirements vary with age, health goals, and physical condition. The American Heart Association suggests 150 minutes of moderate or 75 minutes of high-intensity aerobic exercise weekly for average adults to maintain good cardiovascular health.


The amount of cardiorespiratory endurance required can vary greatly depending on individual health goals, specific age, and physical condition. However, for the average adult, the American Heart Association recommends at least 150 minutes of moderate-intensity or 75 minutes of high-intensity aerobic exercise per week.

This could include activities like brisk walking, swimming, cycling, or running. This helps improve cardiovascular health, boost lung capacity and in general promote a healthier lifestyle. Always remember that it's important to gradually increase the duration and intensity of your workout sessions to prevent injuries.

Explain what distinguishes first class levers from second and third class levers.


Levers are classified into first, second and third class categories based on the different positions of the load, effort and fulcrum.

First class levers :

  • The fulcrum is located inbetween the Effort and the load such as in scissors

Second class levers :

  • The load is inbetween the fulcrum and effort such as in Wheel barrow.

Third class levers :

  • The Effort is inbetween the load and Fulcrum such as in Spade.

Therefore, different classes of levers are based on the position of the fulcrum, load and effort

First class levers are distinguished by the positioning of the fulcrum in-between the load and the effort, unlike second and third class levers where the load or the effort is placed between the other two components.

The categorization of levers into first, second and third class is based on the relative positions of the fulcrum, the load, and the effort. In a first class lever, the fulcrum is between the load and the effort. This is the design of a see-saw, where the fulcrum (the pivot point) is in the middle, and the load and the effort are at the ends. Examples include scissors, pliers, and a crowbar.

On the other hand, in a second class lever, the load is between the effort and the fulcrum (e.g., wheelbarrow), and in a third class lever, the effort is between the load and the fulcrum (e.g., a pair of tweezers).
