Biomechanical Investigation of Lower Limbs during Slope Transformation Running with Different Longitudinal Bending Stiffness Shoes

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This paper researches the effects of running shoes with different longitudinal bending stiffness on lower limb biomechanics. The research content is interesting, but there are the following problems.

1. This paper only researches three kinds of longitudinal bending stiffness, which is too small to draw a convincing conclusion.

2. This paper measured the joint rotation angle through the motion capture system and the ground reaction force through the force measuring plate. How these two types of signals are related to biomechanics?

3. In this paper, the joint angle and joint moment are used to characterize the biomechanics of lower limbs. Whether these indicators can effectively express biomechanical changes?

1.This paper only researches three kinds of longitudinal bending stiffness, which is too small to draw a convincing conclusion.

Response：Thank you very much for your question. This experiment has a stiffness close to that of previous studies. Based on your suggestion, I have added the explanation to the text and highlighted it in red.

2. This paper measured the joint rotation angle through the motion capture system and the ground reaction force through the force measuring plate. How these two types of signals are related to biomechanics?

Response：Thank you for your question. The angle of activity of the joints could be calculated from the motion capture system. In this experiment, the data of the ground reaction force is used with the angle to calculate the moment, power, and work. Joint work could be used to assess the energy consumption of a joint in a particular exercise. Joint power refers to the efficiency of energy conversion in a joint during exercise. These data are an important source of information for sports biomechanics.

3.In this paper, the joint angle and joint moment are used to characterize the biomechanics of lower limbs. Whether these indicators can effectively express biomechanical changes?

Response：Thank you for your question. In sports biomechanics, joint angles and joint moments are an important parameter that helps to understand the motor control of the human body during exercise and the characteristics of various force changes.

Thanks again for your constructive criticism, and time spent to analyze this manuscript. We really appreciate your help and patience.

Reviewer 2 Report

Comments and Suggestions for Authors

1. The research aim - to examine the variations in lower limb biomechanics during the transition from level to uphill while wearing different LBS running shoes.
2. This research is not original. In addition, this work can be considered as a continuation of previously performed research by authors: https://doi.org/10.3390/bioengineering9110607; https://doi.org/0.3389/fphys.2022.907016 . But this research is relevant from a thematic point of view, because to date, lower limb biomechanics during the transition from level to uphill while wearing different LBS running shoes have not been studied.
3. Compared to other published materials in the subject area under study, knowledge about the effect of LBS on the biomechanics of the limb during the transition from level to uphill is added.
4. The method adopted by the authors for solving the problem to achieve the goal can be considered as satisfactory and does not need improvement.?
5. The research carried out by the authors allowed us to expand knowledge in the field of biomechanics of the lower limb. However, the authors did not use these results to formulate conclusions indicating achievement of the stated goal.
6. The Introduction section and research problem statement should be improved to include all relevant studies published within the last 5 years.
Conclusion.

To improve this work, the authors must provide a better overview of the problem state of the art and more rigorously justify the aim of this study. The review should include all significant work related to the evaluation of longitudinal bending stiffness shoes published within the last 5 years.

In the conclusions, it is necessary to note the practical significance of the research results and recommendations for choosing sports shoes during slope transformation running.
