【Research Review】Biomechanical Analysis of the Effects of Carbon-Plate Running Shoe Bending Stiffness on Running Economy (RE): A Study of Elite Athlete Physiological Characteristics (Article 709)

Reference Journal Source: Medicine & Science in Sports & Exercise (MSSE) • International Scientific 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 the cutting-edge literature of Medicine & Science in Sports & Exercise (MSSE), providing a detailed analysis of the performance of subjects in the experimental and control groups. The findings are not only highly valuable for professional coaches, but also provide a scientific basis for amateur runners pursuing their personal best (PB).

Research Background and Mechanical Effect Analysis

In recent years, “super shoes” featuring carbon-fiber plates and super-elastic midsole technology have completely transformed the history of road running. This study focuses on the physiological effects of the longitudinal bending stiffness (LBS) of carbon plates 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 Temperature Regulation

Competing in a marathon under hot and humid conditions places tremendous stress on the circulatory system. This report examines the effects of a systematic 10-14 day heat acclimatization protocol. The results show that heat acclimatization can significantly expand plasma volume by more than 6.5%, promote earlier activation of the sweat glands, improve thermoregulatory capacity, and effectively delay 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 Scientific Conclusions and Practical Recommendations

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

• Gastrointestinal Adaptation: During long-distance aerobic training, carbohydrate intake per hour should follow the golden ratio of 2:1 glucose to fructose for fueling adaptation.
• Quantitative Data Monitoring: It is recommended to use heart rate variability or maximal oxygen uptake zones to continuously assess autonomic nervous system fatigue and overload indicators.
• 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 the Achilles tendon and joints sufficient adaptation time.

Common Research Q&A (FAQ)

Q: Do carbon-plate running shoes provide the same level of improvement for every runner?

A: The research indicates that the degree of improvement shows significant individual variation. Runners with greater plantar stiffness and ankle joint 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 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.
