HSD = high-speed running distance (>14.4 km/h); HR = heart rate; LI = low intensity; MI = moderate intensity; HI = high intensity. Velocity zones: walking = 0–7.19 km/h, jogging = 7.20–14.39 km/h, running = 14.40–21.59 km/h, and sprinting =.21.6 km/h. Acceleration/deceleration zones: low intensity = 0–1.99 m/s
2, moderate intensity = 2–3.99 m/s
2, and high intensity = >4 m/s
