Abstract
Opponent left-handedness does not affect fight outcomes for Ultimate Fighting Championship hall of famers
Highlights
This paper is a commentary on Pollet et al (2013), where both the incidence of left-handedness and its effect on outcomes were analyzed
If we find some indication for a fixed effect of opponent handedness in a Generalized Linear Mixed Model with binomial link (GLMM), after accounting for the nested structure of the data, this suggests that the opponent’s handedness significantly influences the outcome
In the GLMM, with a random intercept for hall of famer, we found no evidence for a handedness effect (B = −0.214(±0.520); Z = −0.412, one-tailed p = 0.34)
Summary
This paper is a commentary on Pollet et al (2013), where both the incidence of left-handedness and its effect on outcomes were analyzed. We explore the effects of left-handedness on fight outcomes in a small sample of elite UFC fighters with multiple fights from the same fighter. For each fight we coded the outcome and handedness of the hall of famer and his opponent, if available.
