Final answer:
The Valsalva maneuver should only be recommended by a personal trainer if the client has exercise technique experience, does not have hypertension, and is resistance trained. The specific exercise such as the bench press is not a deciding factor.
Step-by-step explanation:
The Valsalva maneuver is a specific breathing technique that is often utilized by experienced weightlifters to stabilize the core muscles during heavy lifts.
However, because the maneuver can cause a significant increase in blood pressure, it is not recommended for everyone. When considering whether a personal trainer should recommend the Valsalva maneuver to a client during resistance training exercises, several factors must be considered for safety.
The correct answer to your question is C. II, III, and IV, which means that a personal trainer should consider recommending the Valsalva maneuver to a client if:
- The client has exercise technique experience - as this indicates a familiarity with resistance training and the body awareness necessary to execute the Valsalva maneuver safely.
- The client does not have hypertension - because individuals with hypertension should avoid any activity that may further elevate their blood pressure.
- The client is resistance trained - meaning they have a level of conditioning and understanding of the demands placed on the body during heavy resistance exercises and can therefore use the maneuver effectively.
It does not depend on the specific exercise like the bench press, but rather on the client's experience, health condition, and training status.
