The acceleration dependent validity and reliability of 10 Hz GPS.
OBJECTIVES To examine the validity and inter-unit reliability of 10 Hz GPS for measuring instantaneous velocity during maximal accelerations. DESIGN Experimental. METHODS Two 10 Hz GPS devices secured to a sliding platform mounted on a custom built monorail were towed whilst sprinting maximally over 10 m. Displacement of GPS devices was measured using a laser sampling at 2000 Hz, from which...
متن کاملValidity and Reliability of 5 Hz GPS for Measurement of Non- Linear Cycling Distance and Velocity
This study aimed to determine the validity and reliability of a 5 Hz GPS system for recording distance and velocity during non-linear cycling activity. One trained male cyclist (age 37 yrs; stature 172.4 cm; body mass 74.2 kg) took part in the study. Two non-differential GPS units (Minimax X3, Catapult) were attached securely into the rear pocket of a cycling shirt at approximately the T11-12 v...
متن کاملReliability and Accuracy of 10 Hz GPS Devices for Short-Distance Exercise.
The use of GPS technology for training and research purposes requires a study of the reliability, validity and accuracy of the data generated (Petersen et al., 2009). To date, studies have focused on devices with a logging rate of 1, although it seems that more frequent sampling can increase the accuracy of the information provided by these devices However, we are unaware of any study of the re...
متن کاملValidity and Reliability of 10-Hz Global Positioning System to Assess In-line Movement and Change of Direction
The objectives of the present study were to examine the validity and reliability of the 10 Hz Johan GPS unit in assessing in-line movement and change of direction. The validity was tested against the criterion measure of 200 m track-and-field (track-and-field athletes, n = 8) and 20 m shuttle run endurance test (female soccer players, n = 20). Intra-unit and inter-unit reliability was tested by...
متن کاملValidity and reliability of GPS devices for measuring movement demands of team sports.
There is limited information regarding the validity and reliability of global positioning system (GPS) devices for measuring movement during team sports. The aim of this study was to assess the validity and intra-model reliability of different GPS devices for quantifying high-intensity, intermittent exercise performance. Two moderately trained males each completed eight bouts of a standard circ...
