We aimed to quantify the time–motion characteristics and technical demands of small-sided soccer games (SSGs) played on small, medium and large pitches using a high frequency non-differential global positioning system (NdGPS) that allowed assessment of acceleration and deceleration patterns. Eight male soccer players competed in SSGs comprising 4 × 4 min quarters (3 min recovery) on small (30 × 20 m) medium (40 × 30 m) and large (50 × 40 m) pitch sizes. Time motion analysis using a NdGPS positioning system quantified distance covered sprinting (⩾6.7 m s⁻¹), high speed running (⩾5.8 m s⁻¹) and low (1–2 m s⁻²), medium (2–3 m s⁻²) and high (>3 m s⁻²) acceleration. The frequency of common technical actions (passing, turning, dribbling, shooting, tackling, heading and interceptions) was performed using a hand notation system. SSGs played on medium and large pitches had a greater physical …
