比较健康个体中两个不同的下蹲练习的有效性

实验性的：膝盖过去的脚趾下蹲

将应用具有所需特征的蹲式程序

其他：跪在脚趾上

指示参与者舒适地站立，脚骨盆宽度相距，大约15-30°侧面，手臂在他们的前面伸展。 要求参与者蹲在他们最舒适的地方，直视前方，而没有脚跟离开地板，并保持了2秒钟的位置，然后返回原始的站立位置。 臀部和地板之间的距离是使用尺子垂直测量的，以进行深蹲深度。 进行了三项试验，并将三个试验的平均值用于进一步分析。

实验性的：膝盖不过去的脚趾蹲

将应用具有所需特征的蹲式程序

其他：膝盖不超过脚趾的蹲下

在有限的下蹲运动中，不允许膝盖最前部的位置延伸到脚趾之外。 在有限的下蹲练习中，将木板放置在每只脚的第一脚趾的远端，而60厘米宽的木板限制了膝盖运动。 指示参与者的脚舒适地站立，距离骨盆宽度，侧面约15-30°，他们的手臂伸到他们的前面。 要求参与者蹲在膝盖弯曲的90°，直视前方，而没有脚跟离开地板，并保持位置2秒钟，然后返回原始的站立位置。 下蹲深度是通过使用膝关节上的Goniiomenter测量90°膝盖屈曲的，并使用标尺在臀部和地板之间垂直测量的膝盖屈曲。 进行了三项试验，并将三个试验的平均值用于进一步分析。

Oswestry Disability Index

It was developed to evaluate the degree of loss of function in low back pain. Items question pain severity, self-care, lifting and carrying loads, walking, sitting, standing, sleeping, degree of pain change, travel and social life. Under each item there are six statements in which the patient ticks the one appropriate to his/her situation. The first statement is scored as "0" and the sixth statement is scored as "5". When the total score is calculated, it is multiplied by two and expressed as a percentage. The maximum score is "100" and the minimum score is "0". As the total score increases, the disability level also increases.

Y balance test

The test is a practical functional test that can predict dynamic balance and postural stability. The player's performance improves with balance, flexibility, coordination and power integration. For this test, players stand in the center of a 'Y' shaped arrangement with 3 lines drawn at certain angles. The players are asked to reach in anterior, posterolateral and posteromedial directions using one foot. Three applications are made in each direction and the average of the reach distances is recorded in centimeters. Pre-measured leg length is used to normalize the mean score of these three treatments. Percentage of maximum reach = deflection distance/leg length. Leg length; Spina iliaca anterior superior to the distal point of the medial malleolus. To obtain an overall measure of the Y Balance Test, data from all directions must be averaged to calculate the composite score.

International Physical Activity Questionnaire - Short Form

This questionnaire is a standardized tool for measuring physical activity, developed by researchers from various countries with the support of the World Health Organization (WHO) and Centers for Disease Control (CDC). Questionnaire, four areas of physical activity; It covers work, transportation, housework/gardening, and leisure activities, but also includes questions about time spent sitting as an indicator of inactivity. In each of the four areas, the energy expended in moderate and vigorous activities in the last 7 days, the number of days the activities were performed, and the number of activities performed during the day are recorded. The times are multiplied by the Metabolic Equivalent (MET) values per activity, and the results for all items are added to form the overall physical activity score. The question about sitting is not included in the physical activity score. Classification is made in three categories as physically inactive (3000 MET min/week).
