Crotty, Nora May; Boland, Marie; Mahony, Nick; Donne, Bernard; Fleming, Neil – Measurement in Physical Education and Exercise Science, 2021
This study evaluated the reliability of the portable Lactate Pro 2 analyzer (LP2), and its validity compared to a laboratory-based analyzer, YSI 1500 Sport (YSI). Blood samples (n = 258) were collected during 44 graded incremental rowing tests, with data from 17 tests used to quantify load, heart rate, and oxygen consumption at lactate threshold.…

Derouchey, Joe D.; Tomkinson, Grant R.; Rhoades, Jesse L.; Fitzgerald, John S. – Measurement in Physical Education and Exercise Science, 2020
Anthropometry is important for predicting sports performance. While 3-dimensional (3D) body scanners increase the feasibility of anthropometric assessment, reliability data on athletes are lacking. The aim of this study was to determine the test-retest reliability of a portable, single-camera 3D body scanning system (Styku S100) to assess…
