the MAPEs were significantly different between devices and between ND and D wrist. The Bland-Altman method (bias and limits of agreement) was also used to determine the level of agreement between each wrist tracker and the pedometer for measuring step counts. Data analysis was performed in IBM SPSS

Thus, the focus of this paper was to understand how intra-individual variations over a year within the OA population, regardless of the source or sources of these variations, affect measurement of between-group PA differences and to determine the level of agreement between using a single versus

activPAL functions as a pedometer and provides measures of step cadence and step number, distinguishing stepping from standing. Studies evaluating the validity of the activPAL under laboratory and free-living conditions have reported excellent agreement with ground truth measures of sedentary behavior (i

for “good” reliability was set as R  = .8 as per recommended suggestions, where R  = .7 is considered acceptable and .9 is excellent ( Polit, 2014 ). Test–retest agreement for measures from the UGhent, and Bangsbo and Mohr ( 2011 ) dribbling tests were determined using 95% limits of agreement

agreement would exist in the detection of biomechanical errors between the participants performing the jump-landing task and the expert evaluating the task. This hypothesis was based on the participant’s lack of prior exposure to a feedback intervention and the idea that participants would have trouble

relevant to MVPA including METs and stepping accumulation per epoch. However, few studies have examined the concurrent agreement of MET- or step-based MVPA measured using the activPAL3 micro with the ActiGraph GT3X. Previous research has found that activPAL-measured MVPA has high agreement with ActiGraph

between DXA and ADP ( 3 ). ADP was found to overestimate %BF versus the 5-compartment model in collegiate female athletes ( 24 ). Most of these previous studies assess the agreement between ADP and hydrostatic weighing (as the reference method) to estimate %BF from body density ( 4 , 8 , 12 , 25 , 35 , 36

In Canada, amateur athletes who receive government funding in support of their training are required to sign an agreement with the respective sport organization in order to qualify for the assistance. This illustrates how legal practices are increasingly being used in sport. It is important for participants in sport to understand what the legal elements of such practices are in order to identify those situations in which they have been applied properly, inaccurately , or inappropriately. The purpose of this paper is to analyze the content of the agreements signed by Canadian athletes and the procedures by which they are implemented. The result of this analysis is a list of issues that athletes and administrators may wish to address or improve in order to provide a more fair agreement between the parties.

intermethods agreement in 12- to 14-year-old active males. Methods Subjects and Study Design The present investigation is a cross-sectional analysis as part of a 33-month longitudinal PRO-BONE study (effect of a program of short bouts of exercise on bone health in adolescents involved in different sports), of
