| dc.description.abstract | Background: In swimming, a swimmer’s performance is mostly determined by the
time spent on starts, stroking and turning. The start of a swimming races, especially
sprint races, can account for almost a quarter of race time.
Aim: The aim of this study was to analyse the biomechanics and performance of
three start techniques off the OSB11 starting platform over 15-meters to determine
which of the three is most effective when looking at the three parts that constitute the
start: block time, flight time and underwater time.
Methods: A Quasi-experimental cross over trial-based study design was used to
determine which of three starting techniques (Grab, Track & Kick) was the most
effective off the OSB11 starting block. Ten Swimmers who qualified for junior
nationals from Vineyard Swimming Club participated in the study. Each participant
acted as their own control and were required to perform each start once. All trials
were filmed and analysed on Dartfish pro suite 10. The following variables were
analysed: shoulder angle, hip angle, knee angle, reaction time, movement time, total
block time, flight distance, flight time, flight velocity, entry angle, underwater time,
underwater distance, time to 15-meters. | en_US |
