RELIABILITY OF A SIMPLE NOVEL FIELD TEST FOR THE MEASUREMENT OF PLANTAR FLEXOR MUSCLE STRENGTH

ABSTRACT Introduction When a person is in standing position, the plantar flexor muscles are involved most static and dynamic body movements. Objectives The aim of this study was to investigate trial factorial reliability measuring contractile characteristics PF using simple novel field test. Methods sample consisted 452 healthy subjects, 120 male 332 female. research conducted by means testing method, isometric dynamometry performed conditions. ANOVA used estimate differences among trials, Cronbach’s alpha interclass correlation correlations principal component analysis evaluate contribution each overall variability. Results main findings that trials differed significantly (p<0.000) for maximal force (Fmax) rate development (RFDmax), indicating three procedural were necessary. highly correlated (Fmax, RFDmax, r>0.9), proving reliable, separated second third accounting total Conclusions test measurement recommended proved be as reliable laboratory testing, but easy perform conditions outside scientific or diagnostic institutions, which greatly facilitates work scientists, coaches professionals.
