Correct Answer:
(C) Not enough information
Explanation:
With the information provided in this question, you can’t tell whether Nadia should be inhaling or exhaling at this point. Generally, athlete’s exhale through the concentric portion of the exercise movement, however, the question states that Nadia’s latissimus dorsi is performing an isometric muscle action. This means that the lats are not contracting or lengthening at this time. Additionally, the lats are not a major muscle of the deadlift anyway, the legs are. The question makes no mention of what the legs are doing. The breathing should revolve around the type of movement being performed by the major muscles of the exercise, not an accessory muscle.
