abstract = {Background: Musculotendinous reactive strength is a key factor for the utilization of
elastic energy in sporting activities such as running. AIM: To evaluate the relationship between
musculotendinous reactive strength and lower-limb stiffness during running as well as to identify
age-related differences in both variables. Methods: Fifty-nine amateur endurance runners performed
three 20-cm drop jumps and a constant 3-min easy run on a motorized treadmill. Reactive strength
index and dynamic lower-limb stiffness were calculated with a photoelectric cell system by jumping
and running, respectively. Additionally, sit to stand difference in plantar arch height was assessed as
a static lower-limb stiffness measure. The cluster analysis allows the comparison between younger
and older runners. Results: No significant correlations were found between jumping reactive strength
and running lower-limb stiffness. The younger group performed better at drop jumps (p = 0.023,
ES = 0.82), whereas higher-but-no-significant results were found for reactive strength index and
stiffness-related metrics. Conclusions: Musculotendinous vertical reactiveness may not be transferred
to combined vertical and horizontal movements such as running.},
