. To optimize the training process and control injury risk, practitioners must be able to utilize valid and reliable methods to monitor individual and team-training loads, 2 because without precise quantification of training load, it is not possible to identify the response to training. 3 Training

involvement of these variables is provided in Table  3 , as well as other specific reviews on dietary standardization prior to performance trials ( Jeacocke & Burke, 2010 ), external sources of motivation ( Halperin et al., 2015 ), and the organization of reliable and valid measurements of performance

The 1-repetition maximum (1RM) is defined as the maximum load that can be lifted just once in a given exercise. 1 The 1RM is one of the variables most commonly reported to assess the efficacy of various training and rehabilitation interventions as it is considered a valid indicator of maximal

participants’ cognitive and motivational processes. The dearth of valid measures to assess transfer of responsibility learning in physical education or TPSR programs constitutes a gap in the literature ( Jacobs & Wright, 2017 ). The desire to see learning transfer is certainly not restricted to physical

There are several specialized standalone ergometers for laboratory use and its high level of reliability and validity have been confirmed (Lode, 1 Ergoline, 2 Monark, 2

The purposes of this tutorial are threefold: (a) to clarify the meaning of measurement validity, (b) to provide appropriate validation procedures for use by researchers in adapted physical activity, and (c) to raise the awareness of the limitations of the traditional views on measurement validity. Several validation procedures are described with specific examples from adapted physical activity research based on traditional approaches of providing validity evidence. Conceptual and empirical limitations of the traditional validity framework are discussed. We recommend that several categories of validity evidence should be reported in research studies. We encourage practicing the unified concept of measurement validity (Messick, 1993, 1995) in adapted physical activity research and practice.

displacement plethysmography has shown high reliability and validity for evaluating body composition in many populations, and it has been used frequently as a criterion measure for field techniques in the past two decades, as other methods such as hydrodensitometry and dual-energy X-ray absorptiometry are not

This study attempted to assess the construct validity of the performance profile technique (Butler, 1989) within elite track and field athletics. Twelve elite (senior international honors) athletes (5 male, 7 female: mean age = 21.2, SD = 1.81) completed their profile on five occasions across winter training and the indoor season. Support for the construct validity of the profile was identified by a reduction in profile areas of perceived need (F (4, 44) = 11.77, p < .05) which was congruent with the observed increase in performance (F (4, 44) = 26.30, p < .05) as athletes progressed from winter training to the peak of the competitive indoor season. Trend analyses also identified that areas of perceived need in profile constructs, which were classified as most important to performance, showed a greater and more rapid reduction across the five occasions compared to the least important constructs. However, the results raise some concern over the usefulness of the profile for detecting subtle but important changes in performance and perceived need.
