ental Questionnaire (SPMQ), and Clock Drawing
Test (CDT). Data regarding their sparring exposure were also collected.
Results: The mean ± SD of MMSE score of the participants was 27 ± 1.95 (95% CI), while for
SPMQ and CDT was 9.86 ± 0.35 (95% CI) and 3.92 ± 0.28 (95% CI). Correlations between the
boxers’ performance on the neuropsychological tests and their age and boxing record were non
significant (p>0.05). However, various indices of increased sparring exposure were inversely
correlated with MMSE (p 5 year
** = grade 1 : no contact, grade 2: 1-10 punches per round, grade 3: 11-20 punches per round, grade 4: >
20 punches per round.
