#' Vescovi Timing Gates Sprint Times
#'
#' Timing gates sprint times involving 52 female athletes. Timing gates were located at
#'     5m, 10m, 20m, 30m, and 35m. See \strong{Details} for more information.

#' @details
#' This data-set represents sub-set of data from a total of 220 high-level female athletes
#'    (151 soccer players and 69 field hockey players).  Using a random number generator,
#'    a total of 52 players (35 soccer and 17 field hockey) were selected for this data-set.
#'    Soccer players were older (24.6±3.6 vs. 18.9±2.7 yr, p < 0.001), however there were no
#'    differences for height (167.3±5.9 vs. 167.0±5.7 cm, p = 0.886),
#'    body mass (62.5±5.9 vs. 64.0±9.4 kg, p = 0.500) or any sprint interval time (p > 0.650).
#'
#'    The protocol for assessing linear sprint speed has been described previously (Vescovi 2014,
#'    2016, 2012) and was identical for each cohort.  Briefly, all athletes performed a standardized
#'    warm-up that included general exercises such as jogging, shuffling, multi-directional movements,
#'    and dynamic stretching exercises. Infrared timing gates (Brower Timing, Utah) were positioned at
#'    the start line and at 5, 10, 20, and 35 meters at a height of approximately 1.0 meter.
#'    Participants stood with their lead foot positioned approximately 5 cm behind the initial infrared beam
#'    (i.e., start line). Only forward movement was permitted (no leaning or rocking backwards) and timing
#'    started when the laser of the starting gate was triggered. The best 35 m time, and all associated split
#'    times were kept for analysis.  The assessment of linear sprints using infrared timing gates does not
#'    require familiarization (Moir, Button, Glaister, and Stone 2004).
