During rehabilitation, training is typically performed two to three times per week to ensure optimal tendon load progression while still allowing sufficient muscle recovery. However, this structured rest period creates a paradox often referred to as the “Gap Problem.” Between formal training sessions, muscles may begin to lose elasticity and gradually decondition, which can undermine progress. In addition, inactive periods contribute to tissue stiffness, as peripheral muscles tend to shorten when not regularly engaged. Finally, extended rest without movement may actually prolong pain persistence, delaying effective pain management and slowing the overall recovery process.
