Key Points

To clarify how varying loads during upper limb elevation exercises influence spinal movement in healthy males.
Fifteen healthy males performed shoulder flexion exercises at 0 kg, 0.5 kg, 1.0 kg, and 2.0 kg loads.
Two-dimensional angle analysis was conducted on still images captured from video at various degrees of shoulder flexion.
Angles of the thoracic, thoracolumbar junction, and lumbar spine were calculated.
At 0.5 kg, thoracic angle changes were minimal across shoulder flexion from 15° to 90°.
At 1.0 kg and 2.0 kg, thoracic and lumbar angles changed with increased shoulder flexion, with lumbar movement direction varying at certain angles.
No changes were observed at the thoracolumbar junction across all conditions.

Examines how different exercise loads affect spinal movement in healthy adult males, suggesting implications for clinical application.
