reduced MTP joint work during running for individuals with smaller toes, but the authors did not measure metabolic cost in the same subjects. Thus, it remains unclear whether the reported correlations between heel length and the metabolic cost of running are associated with higher forces in the Achilles

easy, inexpensive, and noninvasive tools to use and allow accurate estimation of the intensity and type of physical activity. In addition, studies in which physical activity is assessed by questionnaires and diaries have shown that these methods are valid and reliable with significant correlation

During this reduction process, various combinations for abbreviating the scoring were tested. Spearman correlations of individual items were analyzed and the items that were most related to

used to examine the relationship between sprint performance and the included kinematic variables. These analyses were based on best individual trial. Correlation values were interpreted categorically as trivial, small, moderate, large, or very large using the scale presented by Hopkins et al. 23 A

position transducer (LPT) during the RP of an STS showed good correlation to maximum gait speed ( r  = .536) and to power measured in the NPR ( r  = .646; Lindemann et al., 2015 ). In community-dwelling older adults, the RP of the STS measured with inertial body sensors has been established as an

determined using Spearman rank correlation coefficients with 95% confidence intervals. The resulting correlation magnitudes were assessed according the following criteria: trivial, .0 to .10; small, .11 to .30; moderate, .31 to .50; large, .51 to .70; very large, .71 to .90; and almost perfect, .91 to 1

hypothesized that AE would be positively associated with both VJH and SS; VJH would have a positive correlation with percentage lean mass, bone-body percentage, calf circumference and thigh circumference, and a negative correlation with body mass index (BMI) and body-fat percentage; SS would have a positive

participants’ behavior under investigation. 11 , 12 , 15 , 16 Also, they increase knowledge on SB because most of them include questions about time spent in different SB or sitting domains. However, self-report tools (eg, single item, diaries/logs or questionnaires) show low correlation with objective data as

using the means of the 3 trials. The significance level was set at .05 for all statistical tests. In addition, relative reliability was assessed using the intraclass correlation coefficient (ICC) in 2-way random models. ICC 1 , 2 and ICC 2 , 3 were used to analyze intrasession and intersession

variance was performed to compare levels of motor coordination, physical activity, and body fat according to age (12, 13, and 14 years old). Pearson correlation coefficients were used to examine the bivariate relationships between physical activity and motor coordination levels, as well as between body fat
