Background  Maximum voluntary bite force (BF) and hand grip strength (HS) serve as muscle strength markers from the jaw motor system and hand motor system.   Aim  To investigate i) differences in maximum BF and HS between dominant and non-dominant sides, ii) differences between repeated tests in the same session and iii) correlation between BF and HS.     Methods Fifteen resistance trained adults (n=6 women, mean age 24 (SD 1.04) years and n=9 men, mean age 27 (SD 4.06) years) were tested with electronic BF and HS devices, with three repeated tests per side. Paired sample T-test was used to detect differences in BF and HS between sides and whether there was a difference between repeated tests. Pearson test was used to determine correlation between BF and HS. P-value <0.05 was considered statistically significant.    Results HS showed differences between dominant and non-dominant sides in three tests (T1 P=<0.0001, T2 P=0.0002 and T3 P=0.0011). BF showed differences between repeated tests in the same session for T1-T2 (P=0.007), T1-T3 (P<0.0001) and T2-T3 (P=0.028) on dominant side and between T1-T2 (P=0.014), T1-T3 (P=0.010) on non-dominant side. Correlation between BF and HS showed r=0.41 for merged data (dominant + non-dominant side) (P=0.02).   Conclusions  In the context of resistance trained adults, the findings showed that BF did not alter between sides while HS did, with higher force production for the dominant hand. Repeated tests showed differences between tests for BF, but not for HS. A weak to moderate correlation could be observed when comparing BF to HS.
