Seasonal changes in the physical activity levels of youth Gaelic football players.

This study quantified changes in physical activity (PA) levels attained by adolescents during Gaelic football (GF) participation across two time points in a season and determined if these changes affected their overall daily PA levels. A total of 130 adolescents (65 females;15.3 ± 1.5 years) wore an activPAL accelerometer to determine total moderate PA (MPA), vigorous PA (VPA) and moderate-to-vigorous PA (MVPA) during a seven-day measurement period, including during GF. The PA measurement was completed at "preseason" (T1) and "in-season" (T2) timepoints. Between T1 and T2, females significantly increased time spent in MVPA daily (p < 0.001, d = 0.95), on Gaelic football days (GFDs) (p = 0.036; d = 0.30), on non-Gaelic football days (NGFDs) (p < 0.001; d = 0.43), and during GF (p < 0.001, d = 0.90). Males did not record any significant changes in PA over time (p > 0.05). At T2, there were no significant differences in time spent in MVPA daily, on GFDs and NGFDs, and during GF between the genders (p > 0.05). The results suggest that the change in daily PA levels by females is a consequence of increased MVPA during GF and reduced PA barriers across the season.
