The Tanita BF-689 demonstrates excellent test-retest reliability, moderately strong absolute agreement with DEXA, and high specificity for overfat and obese classification. Compared to DEXA, the BF-689 is an accurate, portable, and efficient means of assessing %BF in elementary school children.
The purpose of this study was to evaluate landing biomechanics in soccer players following
ACLR during two landing tasks. Eighteen soccer players with an ACLR and 18 sex-matched healthy
control soccer players participated in the study. Planned landing included jumping forward and
landing on the force-plates, whereas unplanned landing included jumping forward to head a
soccer ball and landing on the force-plates. A significant landing×group interaction
was found only for knee flexion angles (p=0.002). Follow-up comparisons showed that
the ACL group landed with greater knee flexion during planned landing compared with unplanned
landing (p<0.001). Significant main effects of landing were found. The unplanned
landing showed reduction in hip flexion (p<0.001), hip extension moments
(p<0.013), knee extension moments (p<0.001), and peak pressure
(p<0.001). A significant main effect for group for gastrocnemius muscle was found
showing that the ACL group landed with reduced gastrocnemius activity (p=0.002).
Unplanned landing showed greater injury predisposing factors compared with planned landing.
The ACL group showed nearly similar landing biomechanics to the control group during both
landing tasks. However, the ACL group used a protective landing strategy by reducing
gastrocnemius activity.
The Azumio® Instant Heart Rate application when used by either platform appears to be a reliable and valid tool to assess pulse rate in healthy individuals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
