What is a challenge athletes may face during the Forestry step test?

The challenge that athletes may face during the Forestry step test primarily relates to the high level of coordination required to perform the test effectively. This test typically involves stepping up and down from a platform in a controlled manner, which demands precise timing, balance, and rhythm. Coordinating the movements of the legs while maintaining proper posture and endurance is crucial for accurately completing the test and obtaining valid results.

In contrast, the other options present either limitations that do not generally apply to the Forestry step test or describe conditions that are not inherent challenges of the test itself. For instance, while coaching can be helpful, athletes are typically capable of completing this test independently. Moreover, the test usually involves stepping on a stable surface, rather than a non-stable one, making that option misleading. Lastly, one of the defining features of the test is time constraints, as athletes are often given a specific duration to complete the steps, contrasting the assertion of unlimited time. Therefore, the need for high coordination stands out as a significant challenge in this context.
