between sessions. Validity A correlational study design was used to assess on-water performance times in relation to the trunk peak isometric force tasks (CORE and SIM absolute and relative scores). Within 1 week following the on-water event, the participants returned to the laboratory to complete the

effect on the accuracy of the sRPE values. Therefore, the aim of this study was to investigate the effect of (1) the survey methods and (2) the time points when RPE was assessed on the correlation between subjective (sRPE) and objective assessment (HR) of TL. Methods Subjects Overall, 85 athletes (58 men

individual FMS™ tests and BMI. The authors hypothesized that there would be a significant correlation between BMI and FMS™ score, a significant correlation between BF% and FMS™ score, and that a greater percentage of obese players would score below the FMS™ cutoff score when compared with players with nBMI

Researchers examined the output for factor loadings on the varimax rotated component matrix to identify items with high

), although one study in young children reported no association at all ( Spessato, Gabbard, Robinson, & Valentini, 2013 ). Brian, Goodway, Stodden, and Tsuda ( 2014 ) found that the correlation between actual and perceived motor competence increased with age (4–5 years, r  = 0.074; 7–8 years, r  = 0.133; 10

Sample entropy quantifies the regularity and or predictability of the CoP time series. High entropy values indicate more irregularity of the time series. Correlation dimension measures the

Finally, the device has proved highly reliable in recognizing walking speed (intraclass correlation coefficient [ICC] = .87; Gorelick, Bizzini, Maffiuletti, Munzinger, & Munzinger, 2009 ). The battery life of the IDEEA monitor provides up to 60 hr

Similar to results of Riemann and Schmitz, 13 the authors found no relationship between the single-leg balance test and SEBT assessments, but did find significant ( P  < .05) correlations ( r  = −.35
