The Effects of Finger Extensor Training on Climbing Performance Compared With Traditional Flexor Training

The purpose of this study, is to assess climbing performance metrics that include max strength testing on a rock climbing hangboard, maximum grip strength, assessment of pain and function using the DASH (disability of the arm, shoulder and hand), and maximum flexor strength and maximum extensor strength in climbers who perform a traditional finger training protocol compared to climbers who train both traditional flexor training protocol and extensor tendons.

Inclusion Criteria: * Adults aged 18 years or older * Recreational to advanced rock climbers as defined by the International Rock Climbing Research Association (IRCRA) scale * Climbing experience of at least 1-2 sessions per week for the past 6 months OR a minimum of 2 years of climbing experience * Ability to commit to two 45-minute training sessions per week for 6 weeks * Access to a hangboard or fingerboard and appropriate loading equipment * Ability to provide informed consent * Willingness to refrain from climbing the day prior to testing sessions Exclusion Criteria: * Upper extremity injury (hand, wrist, elbow, or shoulder) within the past 6 months * Participation in a structured or organized hangboard training protocol within the past 4 months * Climbing less than 1-2 times per week during the past 6 months and less than 2 total years of climbing experience * Age under 18 years * Inability to safely perform maximal isometric finger flexion or extension testing * Inability or unwillingness to comply with the study protocol
