研究目的: |
运动锻炼是目前航天飞行中应用最有效的防护措施,对于心血管、肌肉、骨骼和平衡功能都有良好的防护作用,但空间飞行及卧床实验显示现有的运动防护对于肌骨及跟腱的刺激仍有待加强。不同的足部着地方式对人体生物力学特征有明显的影响,足跟着地会产生更大的平均和峰值载荷率、步长、下肢总功率及髋膝关节的离心功率,而前、中足着地将会增加踝关节的离心功率及跖屈肌(小腿三头肌)的离心载荷。由于骨骼肌肉系统对压力负荷改变的适应和恢复需要一定的时间,因此,若要改变着地方式,需要一定时间的针对性训练进行学习和适应。 在长期失重环境下,需要综合考虑地面冲击力、机械载荷、肌肉激活度、运动防伤等因素衡量不同着地特征的防护效果。我国航天员目前采用的鞋具为传统硬底带支撑的运动鞋,倾向于后脚跟着地。鉴于不同着地方式在触地冲击力、能耗、肌肉力量及髋、膝、踝动力学等方面各有特点及前中足着地对于小腿后群肌肉的刺激优势,我们有理由假设前中足着地能够作为现有在轨训练方式的有效补充,航天员需提前进行针对性训练来适应这种运动姿态。目前尚无失重状态下不同足部着地特征的运动机能变化的研究,相关的力加载负荷、运动学、动力学、能量经济性等参数的变化规律尚不明确。 为了更好的优化在轨锻炼模式,提升防护效果,本项目拟以地面1G重力环境为参照,针对模拟失重和部分重力(月球、火星等)下不同着地特征开展研究,深入分析不同着地特征对人体的力学作用、肌肉激活度以及足底支撑区作用的特征差异,并利用仿真建模,探索关节运动和肌肉力的关系,针对性指导跑步锻炼。 |

Objectives of Study: |
Exercise is currently the most effective protective measure applied in space flight, which has good protective effects on cardiovascular, muscle, skeletal, and balance functions. However, space flight and bed rest experiments have shown that existing exercise protection still needs to be strengthened in stimulating muscle bone and Achilles tendon. Different foot landing styles have a significant impact on the biomechanical characteristics of the human body. The heel landing will produce greater average and peak load rate, step length, lower limb total power and centrifugal power of the hip and knee joints, while the forefoot and midfoot landing will increase the centrifugal power of the ankle joint and the centrifugal load of the plantar flexor muscle (triceps surae). Due to the time required for the adaptation and recovery of the skeletal muscle system to changes in pressure load, it is necessary to undergo targeted training for learning and adaptation in order to change the landing mode. In a long-term weightlessness environment, it is necessary to comprehensively consider factors such as ground impact force, mechanical load, muscle activation, and sports injury prevention to measure the protective effect of different landing characteristics. The footwear currently used by Chinese astronauts is traditional hard soled sports shoes with support, which tend to land on the heel. Given the unique characteristics of different landing styles in terms of impact force, energy consumption, muscle strength, and hip, knee, and ankle dynamics, as well as the stimulation advantages of landing with the front and middle feet for the muscles in the posterior group of the calf, it is reasonable to assume that landing with the front and middle feet can serve as an effective supplement to existing in orbit training methods. Astronauts need to undergo targeted training in advance to adapt to this movement posture. At present, there is no research on the change of movement function of different foot landing characteristics under weightlessness, and the change rule of relevant force load, kinematics, dynamics, energy economy and other parameters is still unclear. In order to better optimize the in orbit exercise mode and improve the protective effect, this project plans to conduct research on different landing characteristics under simulated weightlessness and partial gravity (such as the Moon and Mars), using the 1G gravity environment on the ground as a reference. It will deeply analyze the differences in the mechanical effects, muscle activation, and foot support zone effects of different landing characteristics on the human body, and use simulation modeling to explore the relationship between joint motion and muscle force, Targeted guidance exercises. |

Randomization Procedure (please state who generates the random number sequence and by what method): |
Qualified participants who agreed will be randomly assigned to the front foot landing group and the rear foot landing group in a 1:1 ratio. The front foot landing group will be further divided into 5 groups: 0g, 0.16g, 0.38g, 0.8g, 1g, and the rear foot landing group will be further divided into 5 groups .Participants’ allocations will be according to a computer-generated randomization table. Generation of the allocation sequence, enrollment of participants, and assignment of participants to interventions will be done by the main researcher of the trial. When the subject is enrolled into the study, the subject will be assigned a study number sequentially. If the subject drops out of the study, the assigned study number will not be reused. The random numbers will be sealed in envelopes by an individual other than the trial researchers. The envelopes will be randomly selected by the patients, and they would be assigned to groups according to the contents of the envelope |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
临床观察表由研究者填写,每个入选受试者必须完成临床观察表。完成的临床观察表由临床监查员审查后,第一联移交数据管理员,进行数据录入与管理工作。数据录入与管理由统计学教研室指定数据管理员负责。数据管理员采用R软件编制数据录入程序,进行数据录入与管理。为保证数据的准确性,应由两个数据管理员独立进行双份录入并校对。对报告表中存在的疑问,数据管理员将产生疑问解答表(DRQ),并通过临床监查员向研究者发出询问,研究者应尽快解答并返回,数据管理员根据研究者的回答进行数据修改、确认与录入,必要时可以再次发出DRQ。在盲态审核并确认建立的数据库正确后,由主要研究者、统计分析人员对数据进行锁定,锁定后的数据文件不再做改动。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The Clinical report form is filled out by the investigator, and each selected subject must complete the form. After the clinical monitor reviews the completed Clinical report form, the first page will be handed over to the data administrator for data entry and management. Data entry and management are the responsibility of the designated data administrator of the Statistics Department. Data administrators use EPI Data software to compile data entry procedures for data entry and management. To ensure the accuracy of the data, two data administrators should independently double-entry and proofread. For the questions in the report form, the data administrator will generate a Question Answer Form (DRQ) and send questions to the investigator through the clinical monitor. The researcher should answer and return it as soon as possible. Modify, confirm and enter, and reissue DRQ if necessary. After blindly reviewing and ensuring that the established database is correct, the principal investigator and statistical analyst will lock the data, and the locked data files will not be changed. |
