Musculotendinous adaptations induced by training and competitions in high and low performance triathletes

Abstract

The study investigated musculotendinous adaptations in high- and low-performance triathletes compared to a control group, using ultrasound to analyze the calcaneal tendon and triceps sural muscles. Only the pennation angle of the medial gastrocnemius muscle showed statistically significant differences between the groups (p = 0.002), with higher values in the control group compared to the triathletes. The angle of pennation directly influences the capacity to generate muscle strength and endurance, and stands out for the greater cross-sectional area in efficiently packed muscle fibers. This study suggests that these adaptations may influence performance and predisposition to injury in triathletes.
