Background & Aims: Since today, considerable attention is paid to public sports and according to the definition, a person who exercises 3 times a week for 30 minutes each time is known as a public (non-professional) athlete (1-6), but It is noteworthy that the physical condition of individuals (men and women) are completely different. For this reason, there is a lot of emphasis on the need to apply special standards for these devices. It is recommended that human tools and equipment should be designed and used according to the characteristics of users (6-11). They believe that some sports equipment installed in parks and sports clubs, in addition to not having a standard installation, even the way they are made is not suitable for both women and men (12).
Some of these devices are installed especially in public places; Most of its dimensions and size are suitable for adults and it is not even suitable for men and women to use the same device. This is while due to the lack of necessary standards in the design of these sports devices and its non-compliance with the physical characteristics of different users due to the design and construction of these devices abroad and the use of men and women by one Device with special features Sometimes using them is not only not useful, but also causes irreparable damage to users. The equipment used in athletes' bodybuilding clubs should be designed to fit the body parts of each type of user, in order to have a safe and effective performance (13). Also, park fitness machines and clubs, as one of the equipments that have attracted a lot of users, are no exception to this principle. If the design of these devices is not based on the anthropometric characteristics of users, not only will it reduce the effectiveness of movements and user satisfaction, but it can also cause complications, injuries and physical abnormalities and prevent users from using it. From these devices or even not engaging in sports activities (11). Therefore, due to the importance of this issue, the present study examines the appropriateness of ergonomic indices of bodybuilding machines used for women athletes (people who regularly go to the gym 2 to 3 times a week) and all Such a study deals with the relationship between anthropometric and biomechanical parameters in these individuals. Using the obtained information, it is possible to design devices that are in accordance with the anatomy of the body of Iranian women athletes, so that in addition to professional or non-professional blowing, their body is not injured (15).
On the other hand, due to the topic of anthropometry, researchers and major industrial designers have a very long history and in recent years, access to anthropometric data due to the growing need for such studies in the field of equipment design and human factor engineering. Among the field of sports that is currently considered by the public, has been more important, but in our country has not received much attention and the need for it in recent years is strongly felt and with the Considering that the basic model of these sports equipment is not only Iranian and in terms of major climatic differences as well as the use of one type of equipment taking into account the physical differences between men and women athletes may cause injury and Serious physical problems. As a result, it is very important to ensure that these devices are compatible with the structural characteristics of the community (men and women). In order to increase the efficiency of bodybuilding machines, their important standard and safe features based on ergonomic principles should be used to ensure the general health of users. Therefore, it is necessary to pay more attention to various issues regarding bodybuilding machines and their users.
Ealbaygi et al., By examining the proportionality of ergonomic indices of outdoor bodybuilding devices with anthropometric indices of men, showed that most of the desired dimensions of the devices with the relevant and optimal dimensions of users, there is a significant difference and these devices It is not ergonomic from an anthropometric point of view and it seems necessary to adopt a method for standardization (6). Nazarizadeh et al. Investigated the degree of conformity of ergonomic characteristics of park bodybuilding devices with anthropometric characteristics of female high school students in Tehran. The results indicate that the above devices installed in schools are not suitable for anthropometric measurements of female high school students in terms of dimensions (7). Due to the lack of studies in this field and increasing attention to public sports in the country, the main purpose of this study was to investigate the ergonomic and anthropometric characteristics of axillary press and aviation in vertical and horizontal position in female athletes.
Methods: Among the bodybuilding machines, Nirvana bodybuilding machine in parks and clubs was selected as a sample. Of the 154 people who used the devices regularly, 124 agreed to cooperate after receiving the necessary explanations from the researcher. And their anthropometric characteristics including: height, shoulder height, sitting height, sitting shoulder height, shoulder width, chest depth, elbow thickness, buttock width, buttock-knee length, leg thickness and sole length were measured and then measured with dimensions Bodybuilding machines were compared. First, the dimensions of the park bodybuilding machines were measured and recorded by a plumb line and an engineering meter. Then, in order to collect anthropometric information, the samples were present at the measuring station and from the measurement of their anthropometric features, initial anthropometric data were obtained. In the next step, using these initial data and based on how users are placed on the devices, bodybuilding standards and trigonometric functions, anthropometric computational data were obtained.
The collected data will be statistically analyzed with Excel and SPSS software. Descriptive statistics will be used to describe frequency, standard deviation and Kolmogorov-Smirnov test to examine the natural distribution of data. Also to analyze anthropometric data using kinematic biomechanics and to test the hypotheses from the correlation test (depending on the normality or abnormality of the data from Pearson or Spearman test) to test the hypotheses and determine the level Significance (p <0.05) is used.
Results: The results showed that there is a relationship between ergonomic and anthropometric indices in the axial press machine in the horizontal position (horizontal distance from the back of the seat to the handles and the optimal horizontal distance from the shoulder blades to the grip) in women athletes. Based on the results of Table 2, it can be said that because the calculated correlation coefficient (0.518) with 95% confidence is equal to or equal to the correlation coefficient of the critical table (0.518) and the significance level value (0.000) is less than the error level It is 0.05, so the research hypothesis is confirmed with 95% confidence. There is also a relationship between ergonomic and anthropometric parameters in the axillary press machine in the vertical position (vertical distance from the beginning of the seat to the handles and the optimal vertical distance from the beginning of the buttocks to the grip) in women athletes. Based on the results of Table 3, it can be said that because the calculated correlation coefficient (0.615) with 95% confidence is equal to or equal to the correlation coefficient of the critical table (0.615) and the value of the significance level (0.000) is less than the error level. It is 0.05, so the research hypothesis is confirmed with 95% confidence. The results showed that between the ergonomic and anthropometric parameters of the aviation device, including devices that simulate walking and are suitable for strengthening the cardiovascular system and leg muscles, can even stretch the leg muscles and help balance the body. (The horizontal distance from the bottom of the shoe to the abutment and the optimal horizontal distance from the heel to the toe) There is a relationship in women athletes. In addition, there is a relationship between ergonomic and anthropometric parameters of the aviator (vertical distance from the bottom of the shoe to the support and the optimal vertical distance from the heel to the toe) in female athletes.
Conclusion: According to the research results, there is a relationship between ergonomic indicators of bodybuilding machines and anthropometric features of female athletes. In this regard, research has been conducted in recent years, some examples of which are mentioned below. Conclusion: The findings of the present study showed that axillary and aviation presses installed in parks and open spaces are not ergonomically ergonomically for female users. This mismatch can lead to complications and physical injuries to users. Therefore, users should be careful when using these devices and avoid working with devices that do not fit their body dimensions.
