Efectos de un protocolo de 8 semanas de liberación miofascial con foam roller sobre el perfil fuerza velocidad en el ejercicio de sentadilla y el salto con contramovimiento de deportistas universitarios colombianos

Myofascial release through foam rollers is a strategy used in sports to reduce fatigue and muscle soreness of late post-exercise onset, as well as to optimize neuromuscular performance and flexibility. Currently, the investigation of this strategy has been limited to studying the acute effects of this type of massage on the athlete's recovery and its influence on the range of joint mobility, without delving into how force production could be affected in the long term. Taking the above into account, the objective of this project is to determine the effects of an 8-week myofascial release protocol with foam rollers on the force-velocity profile in the squat and countermovement jump exercise of Colombian university athletes. For this, a quasi-experimental study will be carried out with a group that will receive intervention based on myofascial release with a foam roller for 8 weeks. Regarding the measurement of the variables, the neuromuscular performance of the lower body will be obtained from the countermovement jump (CMJ) protocol quantified through the Optogait device, while a progression protocol will be carried out for the evaluation of the speed-force profile. load to failure (1RM) in the squat exercise, quantifying the average propulsive velocity of each repetition through a Speed4lifts linear position transducer.
