Am I Top of the Pops? Does Feedback of Live GPS Between Sets of Hurling-Specific Small-Sided Games Improve Subsequent Running and Physiological Performance?

The investigation aimed to determine if live feedback of team- and player-specific global positioning system (GPS) running performance data between bouts of hurling small-sided games (SSGs) altered the physical and physiological responses during subsequent bouts of SSGs during a 6-week hurling pre-season period. Twenty-four (n = 24) hurling players (age 25.5 ± 3.2 years; height 177.9 ± 3.2 cm; body mass 83.5 ± 4.5 kg) received either feedback or no feedback during hurling-specific SSGs across a 6-week pre-season period. Teams were assigned to two specific groups, a) GPS live feedback or b) no GPS live feedback (control) for each session, with feedback provided during the SSG rest interval. Running performance (10-Hz, STATSports, Apex, Northern Ireland), heart rate (Polar T31 coded, Polar Electro, Finland), and rating of perceived exertion (RPE) were measured. Data was analyzed using linear mixed-effect models with the effect size (Cohen’s d) used to determine the size of the effect between feedback and non-feedback conditions. Trivial-o-small differences at all time points were observed in heart rate and RPE measures during SSGs, respectively. Trivial-to-moderate effects were observed between feedback and non-feedback conditions for total distance (p = 0.04; ES = 0.25; small) high-speed running (p = 0.043; ES = 0.59; moderate), maximal speed (p = 0.345; ES = 0.11; trivial) and accelerations (p = 0.03; ES = 0.55; moderate). The current data suggests that coaches and applied practitioners may use live GPS feedback to alter the running and physiological performance within hurling-specific SSGs during a pre-season period.
