Table 4B.

Ball vs. non-ball sports: comparisons of pca at different head acceleration bin—vertical canals.

Head acceleration bin
Sport type 3000 deg/s2 4000 deg/s2 5000 deg/s2 6000 deg/s2 7000 deg/s2 8000 deg/s2
Ball 0.987 0.982 0.974 0.959 0.979 0.975
Non-Ball 0.968 0.958 0.935 0.906 0.843 0.808
p-value 0.001 <0.001 <0.001 <0.001 <0.001 <0.001

PCA was estimated using the single bin approach (Equation 2). Using the Bonferroni correction, only p < 0.0027 (highlighted in gray) were consider statistically significant.
