Answer:
Explanation:
To determine which ratios indicate a failure to meet the criteria for balanced endurance among the muscle groups tested, we need to compare the values provided.
Given the trunk endurance test results:
Flexion: 40 seconds
Extension: 60 seconds
Right-side bridge: 46 seconds
Left-side bridge: 44 seconds
Let's examine each option:
A. Flexion: Extension ratio
The flexion to extension ratio is 40 seconds (flexion) to 60 seconds (extension), which simplifies to 2:3. This ratio indicates that for every 2 seconds of flexion endurance, there are 3 seconds of extension endurance.
B. Right side bridge: Left side bridge ratio
The right-side bridge to left-side bridge ratio is 46 seconds (right side) to 44 seconds (left side). This ratio simplifies to 23:22.
C. Right side bridge: extension ratio
The right-side bridge to extension ratio is 46 seconds (right side) to 60 seconds (extension), which does not simplify further.
D. Left-side bridge: extension ratio
The left-side bridge to extension ratio is 44 seconds (left side) to 60 seconds (extension), which also does not simplify further.
To determine if the performance fails to meet the criteria for balanced endurance, we need to compare the ratios. In this case, the only ratio that is significantly imbalanced is the Flexion: Extension ratio (A), which shows a 2:3 ratio. The other ratios (B, C, D) are closer in value and do not indicate a significant imbalance.
Therefore, the client's performance fails to meet the criteria for balanced endurance in the Flexion: Extension ratio (A).
