The reproducibility of the internal load and performance-based responses to simulated amateur boxing

Abstract:
The aim of this study was to examine the reproducibility of the internal load and performance-based responses to repeated bouts of a three-round amateur boxing simulation protocol (BOXFIT). Twenty-eight amateur boxers completed two familiarisation trials before performing two complete trials of the BOXFIT, separated by 4-7 days. To characterise the internal load, mean (HRmean) and peak (HRpeak) heart rate, breath-by-breath oxygen uptake (V ̇O2), aerobic energy expenditure (EEaer), excess carbon dioxide production (CO2excess) and ratings of perceived exertion (RPE) were recorded throughout each round and blood lactate determined post-BOXFIT. Additionally, an indication of the performance-based demands of the BOXFIT was provided by a measure of acceleration of the punches thrown in each round. Analysis revealed there were no significant differences (P > 0.05) between repeated trials in any round for all dependent measures. The typical error (coefficient variation %) for all but one marker of internal load (CO2excess) was 1.2 – 16.5% and reflected a consistency that was sufficient for the detection of moderate changes in variables owing to an intervention. The reproducibility of the punch accelerations was high (CV% range = 2.1 – 2.7%). In general, these findings suggest that the internal load and performance-based efforts recorded during the BOXFIT are reproducible and thereby offers practitioners a method by which meaningful changes impacting on performance could be identified.
