Variability and physical demands of international seam bowlers in one-day and Twenty20 international matches across five years

Objectives To quantify and compare the match demands variability of international One-Day (ODI) with Twenty20 (T20) cricket matches to ODI when competing home away. Design Single cohort, longitudinal observation. Methods Thirteen male seam bowlers across 204 (ODI = 160; T20 44) were investigated over five-years (2015−2019). Using global positioning sensors accelerometers, physical quantified using distance covered at different velocities number entries into high low intensity acceleration deceleration bands. Variability was coefficient variation (CV) smallest worthwhile change. Results Significantly greater (p < 0.05) found for all variables relative minutes played against matches, except 20−25 km h−1 which ODI. Distance between 0−7 km∙h−1 showed no significance difference 0.60). The moderate decelerations (2−4 m∙s2) 0.04) away compared in All other significance. Relative played, ≤4 m∙s2 (within-player CV 75.5%. 72.0%) accelerations >4 79.2%. 77.2%. Between-player 84.7%. 38.8%) >25 65.5%. 64.1%) greatest variability. Conclusions Players are exposed Vs but not matches. Practitioners should be aware large high-speed/intensity
