Question

which test best assesses cardiovascular endurance?
sit - and - reach
pacer test
vertical jump
push - up test
the principle of ______ states that training should gradually become more difficult over time.
intensity
overload
specificity
progression

Explanation:

• For the first question: The PACER (Progressive Aerobic Cardiovascular Endurance Run) test is designed to assess cardiovascular endurance as it involves continuous running which elevates heart rate and tests the body's ability to sustain aerobic activity over time. The sit - and - reach is for flexibility, vertical jump for power, and push - up test for muscular strength.
• For the second question: The principle of progression in fitness training means that the training stimulus (such as intensity, duration, or frequency) should be gradually increased over time to continue making gains. Intensity refers to the level of effort, overload is a more general concept of increasing the training load (but progression specifically emphasizes the gradual increase over time), and specificity is about training for a particular activity.

Answer:

• First question: PACER test
• Second question: Progression
