Do the ergonomic characteristics of armpit and aviation park sports equipment fits with the anthropometric parameters of male users?

The aim of this study was to investigate the ergonomics of armpits and aviators outdoor (park) based on anthropometry parameters of male users.

Among male users of these outdoor park equipment, 120 people from Tehran and in the age range over 20 years (48.38 16 27.27) were selected as a sample. The research variables were the dimensions of the devices and the anthropometry of the male users. The plumb line, engineering meter, ruler, goniometer and static anthropometer kit (caliper) were used to measure the dimensions of the devices and the anthropometry of the users (according to Pheasant instructions). Then, according to the standards of ergonomics and bodybuilding, the science of motor biomechanics and the way of installation on the devices, the fit of the devices was evaluated. Descriptive statistics were used to describe the data and single-group t-test (parametric statistics) and binomial statistics (non-parametric statistics) were used to test the hypotheses.

The results showed that there was a significant difference between most of the desired dimensions of the devices with the relevant and optimal dimensions of users (P <0.05). Therefore, from the anthropometric point of view, these devices are not ergonomic for male users, and it is necessary to adopt a method for the standardization of these devices.

Most dimensions of underarms and outdoor aviators are not ergonomic from the anthropometric point of view of male 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 physical dimensions.
