The Influence of pitch size on running performance and physiological responses during hurling specific small-sided games.

The current study examined how the impact of pitch dimensions influences physiological and running performance during 4 min small-sided games (SSG). Twenty four (n = 24) hurling players were monitored with GPS and heart rate monitors during the in-season training period. Total distance (m) high speed running distance (m) (≥17 km·h), very high speed running distance (≥22 km·h) (m), total accelerations (n), acceleration distance (m) peak and mean velocity (km·h) were calculated. Additionally SSG rate of perceived exertion (RPESSG ;AU), % maximum heart rate and individualised training impulse (iTRIMP; AU) were collected. The current results show that the manipulation of SSG pitch size has an impact on the running performance and physiological responses. The data showed that SSG played on large pitches (SSG80x20m) had greater running demands than medium (SSG60x20m) or small (SSG40x20m) pitches, with significantly more distance covered in all movement categories. Total distance covered at high speed was 354 ± 111 m on a large pitch, 254 ± 72 m on a medium pitch and 198 ± 62 m on a small pitch. Large pitch dimensions resulted in greater physiological and perceptual demands on players (higher %HRmax, iTRIMP [AU] and RPESSG [AU]) compared to medium and small pitches. The current data help applied practitioners to understand further how modifying different aspects of SSG can alter the running and physiological responses of players. Moreover, applied practitioners now have consistent information to design and optimize their training time in mixing the physical, technical and tactical elements within specific SSG pitch dimensions.
