## 4 Discussion
In the intervention group of the study by [PERSON] et al. [38], participants reported a positive improvement in their quality-of-life perception after participating in a 17-week workplace exercise program. The sessions, lasting 15 min each, were conducted remotely three times a week. Improvements were observed in the domains of pain, physical aspects, functional capacity, and emotional performance, with pain being the only domain showing significant improvement. In the present study, pain did not show significant improvement. This discrepancy might be partially explained by [PERSON] et al. [9], who reported that the magnitude of pain perception improvement in different anatomical areas is related to participation, adherence, and commitment to the program. Furthermore, workers who were physically active before the program reported lower pain perception. Considering the biopsychosocial model, pain perception results from a multifactorial interaction between biological, psychological, and social factors. Therefore, optimal strategies for pain prevention and rehabilitation should focus not only on physiological factors, such as workload reduction or isolated physical exercise, but should also incorporate all three elements--physiological, psychological, and social--in a multidisciplinary intervention [39]. The vitality dimension, according to [PERSON] et al. [36], evaluates individual perceptions of energy and fatigue. In this context, [PERSON] et al. [39] demonstrated that physical activity in the workplace can boost social capital among teams and enhance worker vitality. Supporting these findings, [PERSON] et al. [40] verified the effectiveness of exercise programs, especially those combining resistance exercises, stretching, and aerobic activities, in reducing fatigue during and after the workday. These studies reinforce the findings of the present study, emphasizing that implementing workplace exercise programs promotes not only social well-being but also increased vitality and energy among workers. The findings of this study demonstrate that although there were improvements in the overall quality of life score, they were not significant, aligning with the findings of [PERSON] et al. [23], where a workplace exercise program conducted twice a week for ten minutes over twelve months was not considered effective in improving workers' quality of life. In contrast, [PERSON] et al. [29] highlighted that the effects of physical exercise on global health-related quality of life were more pronounced in unhealthy office workers compared to those already considered healthy, suggesting that the effectiveness of interventions may vary depending on the participants' initial health status. In our study, participants had above-average baseline quality of life scores, indicating generally good health at the start of the intervention. This pre-existing level of well-being may have limited the scope for further significant improvement. Based on the present findings, frequent, brief interruptions for physical activity during sedentary periods may enhance physical fitness and health. These results suggest that such interruptions are associated with an improvement in perceived quality of life. The physiological benefits of standing up and breaking up sedentary time highlight the necessity of incorporating breaks during extended periods of sitting, particularly in sedentary work environments [30]. In light of the rise in remote work, exercise interventions designed for this context emerge as a promising strategy for enhancing employee health and well-being. This pilot study aims to demonstrate that even virtual exercise sessions can provide benefits for quality of life.
