(01.10 lc)
lower body muscles are designed to (5 points)

a increase digestive efficiency

b maintain upper spine strength

c transfer power and energy through the torso

d provide oxygen to muscles and tissue

question 2 (5 points)
(01.10 lc)
much of your cardiorespiratory health relies on (5 points)

a using the upper body muscle groups

b using the lower body muscle groups

c maintaining core strength

d maintaining core endurance

Explanation:

Question 1

• Option a: Digestive efficiency is related to digestive organs, not lower body muscles. Eliminate a.
• Option b: Upper spine strength is maintained by upper body and core muscles, not lower body. Eliminate b.
• Option c: Lower body muscles (like legs, glutes) transfer power/energy through the torso during movement (e.g., walking, running). This makes sense.
• Option d: Providing oxygen is the role of the cardiovascular and respiratory systems, not muscles. Eliminate d.

• Option a: Upper body muscle use doesn’t primarily drive cardiorespiratory health. Cardiorespiratory health is more about large - muscle, sustained movements. Eliminate a.
• Option b: Lower body muscle groups (legs) are large and used in activities like walking, running, cycling. Sustained use of these muscles boosts heart and lung function, so cardiorespiratory health relies heavily on them.
• Option c: Core strength is for stability, not the main factor for cardiorespiratory health. Eliminate c.
• Option d: Core endurance is for core stability over time, not the key for cardiorespiratory health. Eliminate d.

Answer:

c. transfer power and energy through the torso
