The influence of a new sole geometry while running.

Area of Science:

• Biomechanics
• Exercise Physiology

Background:

• Running shoe design significantly impacts biomechanical forces on the body.
• Understanding these forces is crucial for injury prevention and performance optimization.

Purpose of the Study:

• To compare ground reaction forces (GRF) between barefoot running, conventional running shoes, and new On running shoe architecture.
• To evaluate the impact of the On running shoe on physiological parameters during submaximal running.

Main Methods:

• Thirty-seven trained male runners participated.
• Data collected during submaximal running in barefoot, conventional shoe, and On shoe conditions.
• Measured biomechanical (GRF, center of pressure) and physiological (heart rate, blood lactate) parameters.

Main Results:

• On running shoes demonstrated GRF similar to conventional shoes, differing from barefoot running.
• No significant difference in running economy was found between On and conventional shoes.
• Slightly lower heart rate (1.3%) and blood lactate (5.5%) were observed with On shoes compared to conventional.
• Increased lateral deviation of the center of pressure was noted with On shoes.

Conclusions:

• The On running shoe's sole architecture results in biomechanical loading similar to conventional running shoes.
• While not altering running economy, the On shoe may offer minor physiological benefits like reduced heart rate and lactate accumulation.
• Further research is needed to determine the performance implications of these physiological changes.
