Volleyball Power Hitting IQ

False. Most hitting-related shoulder injuries occur as the arm is rapidly decelerating or stopping, not accelerating forwards. When a person swings their arm to hit something, the muscles and tendons in the shoulder undergo a lot of stress as they work to slow down the arm's movement. This can lead to injuries such as rotator cuff tears or shoulder impingement.

In the Hand Up movement, the power comes from the rotation of the hips and the transfer of weight from the back foot to the front foot. The wrist should not be held firm as it restricts the natural movement and rotation of the arm, which reduces the power generated. Instead, a loose wrist allows for a whip-like motion, maximizing the speed and force of the hit. Therefore, the statement is false.

The correct answer is "Tilt upwards." In the Draw & Tilt activity, the question is asking about the movement of the shoulders. The shoulders are instructed to tilt upwards, which means they should move in an upward direction. This movement is different from doing the same as the left hand or remaining parallel to the ground.

The ideal movement sequence of the body when hitting harder and safer is to first engage the pelvis, followed by the shoulder, and then the arm. This sequence allows for the generation of power from the lower body through the rotation of the pelvis, which is then transferred to the shoulder and arm. By initiating the movement from the pelvis, the body is able to generate more force and maintain stability, resulting in a harder and safer hit.

During the loading phase, the position of the lower back is slightly rounded forwards. This is because a slight rounding of the lower back helps to engage the core muscles and stabilize the spine, allowing for better force transfer and power generation. It also helps to maintain a more efficient and balanced position, reducing the risk of injury. However, it is important to note that excessive rounding or flexion of the lower back can be detrimental and increase the risk of injury, so a slight rounding is ideal for optimal performance and injury prevention.

The explanation for the correct answer is that while a faster approach can increase the speed and momentum of the athlete, it does not guarantee a higher jump. Other factors such as technique, strength, and timing also play a significant role in achieving a higher vertical jump. Therefore, simply focusing on performing the approach movements faster may not necessarily lead to an increase in vertical jump height.

Encouraging the hitter to work on touching the hands together in front and back of the body will not improve flexibility and speed of movement in the shoulders. This action may actually restrict the movement and limit the range of motion in the shoulders. Therefore, the correct answer is false.

To allow the pelvis to turn freely to the left, the right foot must turn the heel to the sky. This movement helps to create external rotation in the hip, allowing the pelvis to rotate without restriction. By turning the heel upward, the foot and leg are positioned in a way that promotes a greater range of motion in the pelvis, enabling it to rotate more easily to the left.

The shoulder blade muscles, also known as the scapular muscles, play a key role in opening the chest and stretching the chest muscles. These muscles include the rhomboids, trapezius, and serratus anterior. They help to stabilize and move the shoulder blades, allowing for proper alignment and movement of the upper body. By activating and strengthening these muscles, the chest can be opened and the chest muscles can be stretched effectively.

In the Elbow Up movement, the shoulders should tilt to the athlete's left. This means that the left shoulder should be raised slightly higher than the right shoulder. This movement helps to create the proper alignment and positioning for the elbow to be raised up, which is important for certain sports techniques or exercises.
