Which of the following is an example of improved functioning as related to the benefits of muscular strength and endurance training? A. having stronger bones B. easier to do household chores C. lower blood pressure D. larger lung capacity

A - Larger muscles also provide a decreases risk for bone injury

If you wanted to increase your muscular endurance, it would be important to participate in activities that __________. A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle B. decrease the amount of fuel that the muscle can store and increase the time it takes for the muscle to contract C. increase the number of muscles and decrease the size of the muscle cells D. decrease the length of the muscle and increase the thickness of the muscle

A - Muscular endurance revolves around supply oxygen to the muscles in an efficient manner. Usually increase in strength also results in increase in endurance

If you were running a marathon, which type of muscle fibers would be most useful to you? A. slow-twitch B. fast-twitch, type I A C. intermediate-twitch, type II B D. slow-intermediate twitch, type I B

A - Slow twitch muscles contract slower, but have more endurance. Fast twitch muscles contract faster, but have less endurance. Intermediate twitch muscles are the middle ground, but more fast than slow. Type A - Slow twitch Type B I - Intermediate twitch Type B II - Fast twitch

B

True (DUH, its in the name)

T/F - In some sports, muscular strength can be more important than muscular endurance.
