Which of the following is NOT a critical event for the concentric phase of a one-arm shoulder press?

The correct answer indicates that 8° of lateral trunk flexion is not a critical event for the concentric phase of a one-arm shoulder press. In the context of this exercise, the concentric phase refers to the upward movement when the weight is being lifted.

During this phase, the primary focus is on the mechanics and positions that contribute to effective and safe execution of the shoulder press. Scapular upward rotation is essential because it allows the shoulder joint to move effectively and provides stability, thus optimizing the range of motion and force production. Full extension of the arm is also a critical event, as it signifies the culmination of the pressing movement where the arm is fully extended overhead, ensuring that the exercise is completed correctly.

Elbow joint flexion is important because it allows the arm to lift the weight from a lowered position to the overhead position, facilitating the motion required in the concentric phase. However, lateral trunk flexion does not play a significant role in the execution of the one-arm shoulder press. Instead, the movement emphasizes maintaining a stable and upright torso, minimizing unnecessary flexion to ensure effective power transfer and prevent injuries. Therefore, the indication that lateral trunk flexion is not a critical event highlights the importance of proper alignment and stability in this
