1.  POSTACTIVATION POTENTIATION: AN INTRODUCTION 
Improving strength and power in the athlete who is being rehabilitated is a central focus of the sports physical therapist, particularly in the terminal phases of rehabilitation where the emphasis shifts to readiness to return to sport and sports performance enhancement. High load strength training and power training through plyometric exercises are two key components of performance enhancement programs. A current concept in the strength and conditioning literature that is relatively unknown in sports physical therapy is postactivation potentiation (PAP). Even though we have limited data and there may be limited application of the concept of PAP for the sports physical therapist, awareness of this phenomenon is important nonetheless. The purpose of this clinical commentary is to introduce the sports physical therapist to the concept of PAP.

2.  THE ROLE AND IMPLEMENTATION OF ECCENTRIC TRAINING IN ATHLETIC REHABILITATION: TENDINOPATHY, HAMSTRING STRAINS, AND ACL RECONSTRUCTION 
The benefits and proposed physiological mechanisms of eccentric exercise have previously been elucidated and eccentric exercise has been used for well over seventy years. Traditionally, eccentric exercise has been used as a regular component of strength training. However, in recent years, eccentric exercise has been used in rehabilitation to manage a host of conditions. Of note, there is evidence in the literature supporting eccentric exercise for the rehabilitation of tendinopathies, muscle strains, and in anterior cruciate ligament (ACL) rehabilitation. The purpose of this Clinical Commentary is to discuss the physiologic mechanism of eccentric exercise as well as to review the literature regarding the utilization of eccentric training during rehabilitation. A secondary purpose of this commentary is to provide the reader with a framework for the implementation of eccentric training during rehabilitation of tendinopathies, muscle strains, and after ACL reconstruction.
