The same result is detected in the right shoulder moment graph. Individuals with high physical readiness place 2.44-2.61% more load on their shoulders on average compared to the overall evaluated sample group. The most noticeable trends are evident in the right elbow. During the peak moment, it is observed that the group with the lowest physical readiness exerts the highest load moment, approximately 5.53% more than the whole sample average. Additionally, the ergonomics of the group with high physical readiness in the elbow area are very similar to those of

Also, the high physical readiness group has a 4.63% lower moment than the low physical activity group during the first half of the transfer movement.

Analyzing the data by participant age reveals more significant findings. In this group, only two measurements of both shoulders in the 25-35 age group are statistically insignificant. The most ergonomic motion, resulting in the lowest moment, is consistently observed among professionals over 50 years old. In this age group, a positive effect is evident in both elbows and the left shoulder graphs. However, it is important to note that while the right shoulder shows the highest moment extremity within this age group, this does not represent the highest moment observed overall. Furthermore, the extremity of the moment in the elbows is consistently 3.26-4.90% lower in the group of subjects older than 50 years. For the shoulders, the maximum moment of the left shoulder is notably 11.84% lower, while the maximum value of the right shoulder is higher by 6.47% from the overall test sample. These percentage differences illustrate variations within \(\pm\)2.84% for shoulders and \(\pm\)2.19% for elbows across other age groups, which are considered not statistically significant. Figure 9A shows the average neck moment variation in relation to the ergonomic limits derived from [PERSON]'s research and the RULA standard. Across all scenarios, these ergonomic boundaries are consistently exceeded. During each motion cycle phase, an extreme neck moment is generated that surpasses these limits. Specifically, the first extremity accounts for 36.00% of the total motion duration, while the second extremity accounts for 30% of the motion duration. Overall, the ergonomic limit is exceeded 66.00% of the time, averaging a duration of 3.3 \(\pm\) 0.73 s. It is evident that during the transfer, subjects position their necks in such a way that the moment does not exceed the limit, but only for a brief period. Figure 9B shows the shoulder ergonomic limit plot in comparison with right and left shoulder moment plots. On average, shoulder load is 48.57% higher than the ergonomic limit. Figure 9C demonstrates the elbow moment compared to the ergonomic limit. This limit is exceeded throughout the entire transfer motion cycle and largely during the lifting and placing phases. Both elbows experience almost identical moments. The right elbow exceeds the ergonomic limit for 76.68% of the motion duration, while the left elbow exceeds the ergonomic limit for 75.67%. In terms of time, this generally amounts to 3.81 \(\pm\) 0.84 s. Given that the weight being lifted far exceeds the weight used to set the ergonomic limit, the elbow position during the motion should be lowered to minimize the load held in the active elbow position. Table 1 presents cumulative moment data for various data segments. This serves as additional criteria to evaluate different data cross-sections. The analysis of the different scenarios reveals that in the first scenario, all cumulative moments are higher compared to those of the entire sample.
