[Research Review] Biomechanical Quantification of the Effects of Carbon-Plated Shoe Bending Stiffness on Running Economy (RE): A Physiological and Mechanical Analysis — Experimental Report (No. 970)

Reference Journal Source: Medicine & Science in Sports & Exercise (MSSE) • International Research Findings Review Series

In the research field of the road running section, the latest biomechanical analyses and nutritional studies have revealed more subtle physiological codes. This research report is compiled from cutting-edge literature in Medicine & Science in Sports & Exercise (MSSE), providing a detailed analysis of the performance of subjects in both the experimental and control groups. The findings are not only highly valuable for professional coaches, but also provide a scientific basis for citizen-level runners pursuing their personal best (PB).

Research Background and Mechanical Effect Analysis

In recent years, “super shoes” featuring carbon-fiber plates and hyper-elastic midsole technology have completely transformed the history of road running. This study focuses on the physiological effects of the carbon plate’s Longitudinal Bending Stiffness (LBS) on runners’ lower-limb joint moments and Running Economy (RE). The research found that an appropriate LBS can minimize energy loss at the metatarsophalangeal joint during the loading and toe-off phases, thereby reducing the runner’s energy expenditure.

Mechanisms of Heat Acclimatization on Human Blood and Thermoregulation

Competing in a marathon under hot and humid conditions places tremendous stress on the circulatory system. This report explores the effects of a systematic 10–14 day heat acclimatization training protocol. The results show that heat acclimatization can significantly expand plasma volume by more than 6.5%, and promotes earlier activation of the sweat glands, improving thermoregulatory capacity and effectively delaying the onset of excessively high core body temperature during exercise.

Comparative Experimental Data on Carbon Plate Stiffness (LBS) and Running Economy (RE)

Below is the compiled comparison of the experimental control group and multi-dimensional data:

Core Research Conclusions and Practical Recommendations

Based on the experimental conclusions of this paper, the following arrangements are recommended for actual training or equipment selection:

• Hydrodynamic Drag Reduction: During underwater pulling in swimming, focus on the EVF (Early Vertical Forearm) high-elbow catch technique, shifting the fulcrum of force to the latissimus dorsi to prevent rotator cuff strain.
• Gastrointestinal Adaptation: During long-distance aerobic training, carbohydrate intake should be adapted using a 2:1 golden ratio of glucose to fructose per hour.
• Biomechanical Feedback: Strengthening the gluteus medius and deep core muscles can significantly improve pelvic tilt during the stance phase, preventing uneven patellar loading under high intensity.
• Equipment Efficacy Adaptation: When using carbon-fiber stiffened plates or deep-section wheels, gradually increase weekly mileage to allow sufficient adaptation time for the Achilles tendon and joints.

Common Research Q&A (FAQ)

Q: Does a carbon-plated shoe provide the same level of improvement for every runner?

A: The research indicates that the degree of improvement exhibits significant individual variation. Runners with greater plantar stiffness and ankle strength can more efficiently harness the elastic return of the carbon plate.

Q: What is the recommended intensity for heat acclimatization training?

A: It is recommended to perform easy jogging below the aerobic threshold, either indoors or outdoors, at temperatures of 32–38°C, for 60–90 minutes per session. This can achieve 80% of the physiological characteristics of heat acclimatization within 10 days.
