ecological validity of the assessment, it is beneficial for controlling environmental factors such as wind, rain, temperature, and humidity, especially when the effects of these variables on fast-bowling skill is not understood. In attempt to enhance the ecological validity of the assessment, 5 of the

-phase process (Phase 1: scale development, Phase 2: assessment of factorial validity, and Phase 3: assessment of test–retest reliability). Global estimates report that <20% of adolescents are sufficiently active (with a marked decline in physical activity of ~7% each year during adolescence; Hallal et

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

investigating the comparative validity of measures of automatic associations. Measurement as a Persistent Challenge in the Study of Automatic Associations Compared with explicit constructs, implicit processes are greatly understudied and remain poorly understood. Before exercise-specific dual-process theories

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

. Validity is considered as one of the psychometric properties emphasized by researchers in order to evaluate the accuracy and significance of the obtained test scores. The measure expresses the extent of accuracy to which the test material can evaluate the constructs, properties, roles or abilities for

criterion validation of the activPAL3 has been performed. Previously, Sellers, Dall, Grant, and Stansfield ( 2016b ) examined the validity and reliability for activity classification and step detection in a population of eight young and 20 adult participants. Participants performed a scripted routine and a

information output from the device (i.e., features) should be both valid and reliable ( Duking, Fuss, Holmberg, & Sperlich, 2018 ). However, the literature assessing activity trackers is voluminous, with varied protocols, brands and versions, locations worn, and modes of testing. This makes it challenging to

Key Points ▸ The reliability of manual goniometry is highly dependent on the examiner. ▸ The concurrent validity of the inertial goniometer was very high compared to a 2D analysis. ▸ The ease of use, time efficiency, and concurrent validity supports the application of inertial goniometry. Range of

stage, the required running speed increases, until the child can no longer run the 20-m distance in time with the audio signal (on 2 consecutive occasions) or when the child stops due to volitional fatigue. The test has moderate criterion validity against gas-analyzed peak V ˙ O 2 (mL/kg/min) (see
