Abstract: Tri-axial accelerometry has previously been shown to provide a reliable technique for the assessment of MMA specific activities during isolated training movements. However, this method has yet to be used for the analysis of competition demands. Six male MMA trained participants took part in a single simulated MMA bout each comprising of 3 rounds of 5 minutes with 1 minute rest between rounds. Participants wore a tri-axial accelerometer positioned between the T3-T4 vertebrae in a harness. Mean accumulated player load (PLdACC) and mean accumulated player load per minute (PLdACC.min-1) were calculated for each round and for the bout overall. Capillary blood lactate samples were also taken prior to warm up, post warm up, upon completion of each round and 5 minutes post bout whilst video based time motion analysis was completed post hoc. PLdACC was 224.32 ± 26.59 au, whilst PLdACC.min-1 was 14.91 ± 1.78 au. Participants had a mean post bout lactate of 9.25 ± 2.96 mmol.L whilst there was significant differences in lactate levels across all six sampling points. The group was found to have a work rest ratio (W:R) of 1:1.01 whilst a significant difference was found between bout winners and bout losers in terms of the amount of successful takedowns.
