Abstract

Purpose: As a multi-disciplined combat sport, relationships between external and internal training loads and intensities of mixed martial arts (MMA) have not been described. The aim of this study was to determine the external loads and intensities of MMA training categories and their relationship to internal loads and intensities. Methods: 20 MMA athletes (age=23.3±5.3, mass=72.1±7.2kg, stature=171.5±8.4cm) were observed for 2 consecutive weeks. Internal load and intensity (sRPE) were calculated using Foster’s RPE for the session overall (sRPE-TL) and segmented RPE (segRPE-TL) for each training category: warm-up; striking drills; wrestling drills; Brazilian jiujitsu (BJJ) drills; striking sparring; wrestling sparring; BJJ sparring; MMA sparring. External load and intensity were measured via Catapult Optimeye S5 for the full duration of each session using Playerload (PLdACC) and PLdACC per minute (PLdACC∙min-1). Differences in loads between categories and days was assessed via Bayesian ANOVA (BF10≥3). Predictive relationships between internal and external variables were calculated using Bayesian regression. Results: Session overall sRPE-TL=448.6±191.1AU; PLdACC=310.6±112AU. Category segRPE-TL range=33.8±22.6AU (warm-up) – 122.8±54.6AU (BJJ drills). Category PLdACC range=44±36.3AU (warm-up) – 125±58.8AU (MMA sparring). Neither sRPE-TL nor PLdACC changed between days. PLdACC was different between categories. Evidence for regressions was strong-decisive except for BJJ drills (BF10=7, mod). R2 range=.50-.77, except for warm up (R2=.17), BJJ drills (R2=.27), BJJ sparring (R2=.49) and session overall (R2=.13). Conclusions: Whilst MMA training categories may be differentiated in terms of external load, overall session external load does not change within or between weeks. Resultant regression equations may be used to appropriately plan MMA technical/tactical training loads.
