Functional capacity and risk of injury in CrossFit practitioners measured through smartphone apps.

Background: CrossFit is a high intensity functional training that tends to challenge physical limits. The objectives of this study were to assess functional capacity, prevalence and risk of injury in CrossFit practitioners.

Methods: This cross-sectional, observational and prospective study evaluate the rate of injuries that occurred in CrossFit practitioners in the last 12 months and their functional capacities.

Muscle excitation, force response, and efficiency during explosive force production after diacutaneous fibrolysis on lateral gastrocnemius of recreational athletes.

Objective: Fibrous adhesions impair normal muscle mechanics. The present study aimed to assess lateral gastrocnemius muscle excitation, isometric force response, and neuromuscular efficiency during explosive force in plantarflexion before and after diacutaneous fibrolysis.

Methods: Thirty-five recreational athletes were allocated in the intervention group (n = 20) treated with diacutaneous fibrolysis, while the sham group (n = 15) was treated with placebo diacutaneous fibrolysis.
