Which of the following is essential to discuss with clients before sports massage?

Discussing a client's medical history is essential before conducting a sports massage because it provides important information about any pre-existing conditions, injuries, or medications that may impact the treatment. Understanding the client's health background ensures that the practitioner can tailor the massage techniques appropriately and safely. For instance, if a client has a history of certain orthopedic conditions, sports massage techniques may need to be modified to avoid further injury. Additionally, awareness of any medical procedures or ongoing treatment can help in assessing contraindications and preventing adverse reactions during the massage.

While understanding a client's favorite sports, exercise routine, or dietary habits may also be relevant to personalizing the session, they do not carry the same level of risk as information regarding the client's medical history. This area is foundational for ensuring the client's safety and well-being during the massage therapy session.
