Which of the following is a sign that a training program may require adjustments?

A training program may require adjustments if there is persistent fatigue in individuals participating in it. Persistent fatigue often indicates that the program might be too intense, not allowing adequate recovery, or not aligned with the participants' current fitness levels. When individuals consistently feel fatigued, it suggests that the workload may be overwhelming or that there are underlying issues such as inadequate nutrition or rest that aren't being addressed. This sign is crucial because it can lead to burnout, decreased motivation, and increased risk of injury if not addressed promptly.

In contrast, improved sleep quality suggests that the training is beneficial and may be positively impacting overall health. Increased participation in the program can indicate that it is engaging and effective. Positive feedback from peers is also a signal that the program is well-received and likely fulfilling its intended purpose. These signs reflect a successful training environment rather than highlighting the need for adjustments.
