Was PBM originally devised in response to the lack of pain based models of training available?

Yes, Pain-Based Models (PBM) were originally devised in response to a perceived deficiency in training models that adequately addressed pain management and its impact on performance. Traditional training models often overlooked the complexities of pain in athletic and rehabilitation contexts. PBM seeks to incorporate an understanding of pain as a critical factor influencing training and recovery, thereby enhancing overall effectiveness and safety in training regimens.
