Examine the statements about long jump technique phases:

1. The run-up on the runway builds peak momentum prior to takeoff.

2. Takeoff involves pushing from the weaker leg to ensure stability.

Which statements are accurate?

The correct answer is Only 1.

Let us analyze each statement regarding the long jump technique phases:

1. Statement 1: "The run-up on the runway builds peak momentum prior to takeoff."
This statement is accurate. The main objective of the run-up (or approach phase) in the long jump is to accelerate to maximum controllable velocity. Building peak horizontal velocity and momentum prior to hitting the takeoff board is essential for achieving maximum distance during the flight phase.

2. Statement 2: "Takeoff involves pushing from the weaker leg to ensure stability."
This statement is inaccurate. The takeoff phase requires the athlete to push off explosively using their stronger or dominant leg (often referred to as the takeoff leg) to convert horizontal momentum into vertical lift. Pushing off from the weaker leg would decrease stability, reduce jump height, and result in sub-optimal power generation.

Therefore, only Statement 1 is correct.
