Final answer:
Swimming (option d) is not an example of a non-repetitive skill because it involves continuous, repetitive motions. Catching a ball giving with the motion and entering water with a hand-first diver position reduce impact and potential injury.
Step-by-step explanation:
The student has asked which is not an example of a non-repetitive skill: tower dive, baseball bunt, shot put, or swimming. Non-repetitive skills are actions in sports or activities that are unique and not rhythmic or patterned. The answer is swimming, which unlike the other options, can be a continuous, repetitive motion rather than a one-off skill.
While catching a ball, giving with the ball allows for a softer catch and reduces the impact by moving your hands toward your body. However, keeping your hands still typically results in a harder impact and might cause the ball to bounce off or may cause injury. Similarly, hitting the water with a full palm, representing a belly flop, creates a large surface area impact that can be painful due to the resistance of the water. In contrast, diving with your hand leading with fingers creates less resistance and pain. It is similar to a swimmer performing a dive versus a belly flop.
Therefore, it is advisable to use the diving hand orientation when entering water to minimize resistance and avoid potential injury that could result from a belly flop. The catching ball example shows the importance of adaptability to reduce impact, similar to how a diver adjusts the body when entering water.
