The Internet of Things (IoT) is one technology that can revolutionize traditional methods and transform sports infrastructure. To promote the adoption of IoT effectively, it's vital for sports manager to understand the factors that positively and negatively affect it. The aim of this study was to investigate how perceived risk impacts people's willingness to use IoT technology in sports. This quantitative study used a survey method and applied a descriptive approach. The statistical population included Iranian athletes, and 394 individuals completed questionnaires using a non-probability sampling method. Data analysis was performed using Smart PLS3 software. Results showed that perceived risk has a direct and negative impact on perceived ease of use, willingness to use, and perceived usefulness. However, its effect on attitude towards use was insignificant. The study also confirmed the positive impact of perceived ease of use on perceived usefulness and attitude towards use. Perceived usefulness had a greater effect on the latter variable. Additionally, perceived usefulness had a significant positive impact on willingness to use IoT technology in sports, as did attitude towards use. Attitude towards use also had a significant positive impact on willingness to use IoT technology in sports. The study recommends implementing strategies to enhance and improve perceived usefulness, ease of use, and attitude towards use while reducing perceived risk to increase acceptance and willingness to use IoT technology in sports.

Purpose: This study aimed to investigate the effect of a pulmonary rehabilitation exercise program on post-COVID-19 patients. Method : Three patients (two women and one man) with different severities, from moderate to severe, were selected. Blood pressure, heart rate, blood oxygen, and body function were measured at the beginning and end of the exercises, which included 12 sessions of arm and leg cycle ergometer and treadmill with adjustable resistance levels. Patients’ functionality was assessed using the Barthel index, and their quality of life was assessed using the SF-36 questionnaire. Results: Regarding the first patient, oxygen saturation increased from 85 to 95, the 6-minute walk test (6MWT) result increased from 0 to 420 meters, and the Barthel index increased from 35 to 85. For the second patient, arterial oxygen saturation increased from 82 to 92, the 6-minute walk test (6MWT) result increased from 0 to 390 meters, and the Barthel index increased from 30 to 90. For the third patient, arterial oxygen saturation increased from 87 to 96, the 6-minute walk test (6MWT) result increased from 320 to 510 meters, and the Barthel index increased from 60 to 85. All the patients showed improvements in their physical functions, such as walking, personal affairs, and quality of life. This functional improvement was higher in more severe levels of the disease. Conclusion: Based on the results, it seems that pulmonary rehabilitation exercises for post-COVID-19 patients can contribute to the improvement of their status, arterial oxygen level, quality of life, and pulmonary functionality.
