JCOA The Japanese Clinical Orthopaedic Association the questionnaire survey on the physical changes after the self-restraint of outdoor activities with the COVID-19 crisis (2nd report).

BACKGROUND: In March 2021, the 3rd wave of COVID-19 pandemic had ended and the second emergency declaration in January in Tokyo and 3 other prefectures had been lifted. The restrictions on the social activities imposed on the Japanese people and it had become established as "the new lifestyle norm" for each age group. Following our first survey, we conducted a questionnaire survey again to determine the physical changes in all age groups and compared the findings. METHODS: The 1st survey was conducted after the initial emergency declaration lifted in July 2020, and the 2nd survey was 10 months after the first survey March 2021. And the analysis was conducted by simple and cross tabulation. RESULTS: The number of valid responses were obtained over 12,000 samples for the both surveys. One year later, "Corona locomo" decreased from the previous year in all age groups, especially school students, while it increased in "80s∼". "Corona stress" decreased sharply among children, especially elementary school students, while it increased slightly in 20s, 30s, and "80s∼". The physical condition was closely related to the proportion of exercising population and duration in each age group. CONCLUSIONS: "The new lifestyle norm" as a countermeasure against COVID-19 crisis had a significant influence on physical condition in each age group as "the secondary health damage". Forcusing on "With Corona era", it is considered necessary for preventing "locomo-frail", to improve the exercise lifestyles by selecting tailor-made training methods.

JCOA The Japanese Clinical Orthopaedic Association the questionnaire survey on the physical changes after the self-restraint of outdoor activities with the COVID-19 crisis- corona locomo and corona stress.

BACKGROUND: Problems with COVD-19 are not limited to the infection itself, but also include the secondary health damage arising from the prolonged self-restraint, which has affected all age groups in the Japanese population. Numerous studies have reported clear evidence of the secondary health damage. Published reports cover a wide range of damages, from locomotive dysfunction caused by decreased physical activity to decreased cognitive function and changes in eating and oral functions, and further to decreased opportunities for social participation. Such damage can also lead to worsening of so-called frailty. Under this circumstance, orthopedic surgeons conducted a questionnaire survey to determine the physical changes observed after the start of the COVD-19 self-restraint period. In this article, we report findings of the survey, along with some literature considerations. METHODS: The survey was started two months after the state of emergency in Japan was lifted, July 20 to August 12, 2020 (16 days total). And the analysis was conducted by simple and cross tabulation. RESULTS: Valid responses to the questionnaire were obtained from 12,254 participants. Approximately 40% of the subjects felt a lack of physical strength (Corona stress), with the percentage peaking in high school, in the elderly it remained rather below average. On the other hand, locomotive dysfunction (Corona locomo) increased with age, independent of physical activity, and was not correlated with Corona stress. CONCLUSIONS: Japanese citizens need to change their behaviors for the purpose of improving their exercise and lifestyle habits towards shifting to a new lifestyle norm. Looking ahead to the ``With Corona'' era, it is considered necessary by selecting a tailor-made training method suitable for each age group.
