Abstract

There is a great interest in coaches and fitness trainers to define the physical demands of training, in order to optimize the training process, to evaluate the players’ performance and provide suitable recovery time and nutrition. The determination of training load can be particularly challenging in Rugby Union, a team sport played by 15 players of highly variable build, that is characterized by short, high intensity efforts (struggle, impacts, sprinting) and longer, low intensity activities (standing still, walking, jogging).Our study aimed at applying a heart rate based approach to measure absolute and relative workloads in two typologies of training, typically used in rugby union: team session (TS) and unit training (UT).Methods15 forwards (FW) and 15 backs (BK) from Venezia Mestre Rugby (elite Italian senior championship) undertook one incremental test to exhaustion on the treadmill to determine individual VO2max, heart rate (HR) at max and HR/VO2 relationship. Furthermore, within the following month, HR was continuously monitored during 12 training sessions (6 TS and 6 UT).For each training session, we determined absolute (Kcal*kg-1*min-1) and relative intensity (%HRmax, %VO2max,). Mean and standard deviation were calculated in FW and BK for TS and UT sessions and compared by t test (p< 0.05).Results & DiscussionThe athletes were 24±3 years old, a 12±3 years playing experience and a VO2max of 47±5 ml*kg-1*min-1.
