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

This hypothesis was based on the participant’s lack of prior exposure to a feedback intervention and the idea that participants would have trouble

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.

Context:
The agreement of clinical judgments of endfeel between certified athletic trainers and orthopedic surgeons is not known.
Objectives:
To examine agreement of clinical judgments of endfeel between sample populations and explore the influence of clinician technique on sensitivity for determining ACL injury when performing an isolated examination procedure.
Design:
Randomized, blinded, controlled clinical trials.
Setting:
Laboratory.
Subjects:
1 orthopedic surgeon, 22 certified athletic trainers, and 12 model patients.
Main Outcome Measures:
Kappa coefficients were calculated to determine the agreement of clinical judgments of endfeel between the 2 populations sampled. Lachman-test sensitivity was measured using true positive and false negative interpretations.
Results:
Concurrence was poor for clinical judgments of endfeel. Sensitivity varied according to clinician technique.
Conclusion:
Agreement between the 2 populations sampled was influenced by the examiners’ diagnostic skills and their capacity to properly perform and interpret the Lachman test.

Parents and 531 students (46% males, 78% white) completed equivalent questionnaires. Agreement between student and parent responses to questions about hypothesized physical activity (PA) correlates was assessed. Relationships between hypothesized correlates and an objective measure of student’s moderate- to-vigorous physical activity (MVPA) in a subset of 177 students were also investigated. Agreement between student and parent ranged from r = .34 to .64 for PA correlates. Spearman correlations between MVPA and PA correlates ranged from −.04 to .21 for student report and −.14 to .32 for parent report, and there were no statistical differences for 8 out of 9 correlations between parent and student. Parents can provide useful data on PA correlates for students in Grades 7–12.

Context:
The intrinsic foot muscle test (IFMT) is purported to identify intrinsic foot muscle (IFM) weakness during clinical examination. However, before this test can be used in clinical practice the clinometric properties must be determined. In addition, it is unclear if the IFMT provides information regarding the integrity of the foot arch beyond static foot posture assessments such as the navicular drop test (NDT).
Objective:
To determine the reliability of the IFMT as well as its correlation with the NDT.
Setting:
Laboratory.
Patients or other Participants:
Two novice ATs served as the raters. The NDT was assessed by a third investigator during the first session. Twenty-five participants (16 females, 9 males; age: 22.4 ± 1.7 years; height: 170.8 ± 10.2 cm; mass: 73.5 ± 12.8 kg) completed two data collection sessions separated by one week.
Interventions:
During each session the IFMT was assessed bilaterally in a counterbalanced order by the raters. Each test was rated simultaneously by both raters during each trial and the raters were blinded to each other’s results during and between test sessions.
Main Outcome Measures:
The independent variable was time (session one and session two) and the dependent variables included rating on the IFMT and navicular drop height.
Results:
Intrarater agreement was poor to fair (κ = .03−.41) and interrater agreement was fair to moderate (κ = .25−.60). Post hoc Wilcoxon rank tests demonstrated a significant number of participants improved between sessions for both raters. A weak correlation was observed between the NDT and IFMT for both right (r = −.14 to .04, p < .49) and left (r = −.19 to .07, p < .37) feet.
conclusion:
The IFMT demonstrated poor to fair intrarater and fair to moderate interrater agreement, suggesting future research is needed to modify this method of measuring IFM function. The improvement between sessions indicates a potential familiarization period within the test. The weak correlation between the IFMT and NDT indicates these tests evaluate different aspects of foot function.
