Final answer:
The best adaptation for a wheelchair basketball session for new players is to lower the basketball net, making it easier for players to score and facilitating skill development in a sport where precision is key due to the small target size.
Step-by-step explanation:
The best adaptation to use when leading a wheelchair basketball session for a group of adolescents learning to maneuver sports wheelchairs would be D. Lower the basketball net. This adaptation allows players to reach the goal more easily, aligning the challenge with their current skill level while using sports wheelchairs. Lowering the net can significantly increase the success rate of scoring and improve the overall enjoyment and engagement in the learning process. It provides a more attainable target, which is crucial in basketball considering that the basket is only 18 inches across and offers little room for error. This adjustment can facilitate a better learning curve and ensure that those just starting do not get discouraged.
In contrast, using a smaller ball (A) would not necessarily accommodate the specific needs of wheelchair basketball players. Shortening the game time (B) could help manage fatigue but would not assist in skill development related to shooting. Reducing the size of the court (C) may make the game more manageable in terms of space, but it does not address the core challenge of shooting the basketball into the hoop. Therefore, lowering the hoop, while ensuring the location has sufficient space to prevent collisions, would be the most effective adaptation for beginners in sports wheelchairs.
