Segmental coordination (PL\u2013LB, LB\u2013LT, LT\u2013UT) was analyzed using 3D motion capture and a modified vector coding method across concentric and eccentric phases. Coordination pattern frequencies and variability were statistically assessed using repeated-measures ANOVA and Statistical Parametric Mapping (SPM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In-phase coordination patterns were dominant in the PL\u2013LB and LB\u2013LT couplings across all intensities. However, pyramidal loading led to increased distal dominance and reduced proximal contribution, particularly at 90% intensity. Significant differences in coordination patterns were observed between the two loading strategies, while coordination variability did not differ significantly.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Pyramidal loading imposes greater neuromechanical demands on trunk segments, increasing the risk of coordination breakdown and potential injury in distal spinal regions.
