Rugby union is a high-intensity invasion game characterisedby contact events (most frequently the tackle and ruck). Success in key defining moments (i.e. tackle breaks, turnovers,scrums) in elite level rugby union is therefore largely depen-dent on technical characteristics, and physical qualities in-cluding strength and speed (1). Understanding changes inforce characteristics across the full English professional rugby union season is therefore important for creating and monitor-ing strength and conditioning programmes. Aim The aim of this study was to examine changes in force out-put, rate of force development (RFD), and jump performance across the full season in elite male English rugby union players. Design Cross-sectional study. Methods Anthropometry, counter movement jump (CMJ), squat jump(SJ), drop jump (DJ), and isometric mid-thigh pull (IMTP) measures were obtained in four separate trials (July, September, January, April) across a forty-one week season.
