Abstract Resume

Background: Individuals with experience in sports that can be played as exergame (EXG) could reach different intensities those without experience. Additionally, they also would
present gestures and efforts distinct from non-experienced people. The aim of present study was to evaluate the effort level in an EXG combat sport, considering Taekwondo experience.

Methods: Were enrolled 14 boys (12 to 16 yo), 7 with more than 6 months of experience in Taekwondo (TKD group) and 7 physically active with no experience in combat sports (NTKD). Both
groups showed no experience in the Xbox 360™ and with the EXG Fighters Uncaged© (Ubisoft Entertainment S.A). The participants played a single match of 6-round against the same virtual opponent. The
heart rate (HR) were collected before (HRREST) and during the match to obtain peak (HRPEAK) and mean (HRMEAN) values. The percentage of age-predicted maximal HR (%HRMAX) was calculated using the 208 -
(0.7*age) equation. We punctured 15µl of blood from earlobe before, immediately after, 2min, 4min and 6min after the match, and the lactate concentration [LAC] was analyzed in Yellow Springs 2300®.
The rate of perceived effort (RPE, 0-10 OMNI scale) was registered after the match. The video analysis was conducted by Taekwondo specialist, who quantified the techniques. Data were show with mean
(SD), the comparisons between groups (TKD and NTKD) and between techniques (kicks and punches) were made with 2-way ANOVA, with Tukey post-hoc. Were conducted bivariate correlations with Pearson’s
test. The significance level was set in 5%.

Results: The mean time of practice was 1min07s to TKD and 1min10s to NTKD group. We found no differences between groups to RPE, HRPEAK (TKD=90.1±14.7% and NTKD=79.8±17.2%; t=1.7;
p=.25) and HRMEAN (TKD=74.2±15.7% and NTKD=66.6±18%; t=1.2; p=.41). To [LAC], were found no differences between groups (F1,6=2.9; p=.14), but between moments (F4,3=13.4; p<.001), with significant
interactions (F4,3=5.6; p=.002). Were found higher values in TKD group in the 4th (3.9±1.13 vs 2.37±0.61 mmol/L; t=4.31; p=.005) and 6th (3.98±1.63 mmol/L vs 2.2±0.67 mmol/L; t=5.01; p=.002) minutes.
We found differences in the type of techniques applied (F1,6=52.5; p<.001) with significant interactions (F1,6=10.6; p=.02). Both groups used more punches than kicks (83±22 punches vs 23±11 kicks;
t=12.9; p<.001), and the NTKD groups applied more punches (96±21 vs 69±22 punches; t=4.2; p=.03). We found significant correlations between kicks and RPE (r=-.69; p=.01) and between punches and [LAC]
in the 2nd (r=.64; p=.02) and 4th min (r=.61; p=.03), and with HRMEAN (r=.61; p=.03).

Conclusions: We found small differences in physiological variables between groups, with higher values to [LAC] during the 4th and 6th min post-EXG in TKD group. The technical
differences were small, with more punches in NTKD. We highlight significant increments in HR and [LAC] during EXG combat's practice, despite no effect of previous experience in combat sports.
