Physical performance is associated with visual acuity in university students: results of a school-based study.

OBJECTIVE: The aim of our study is to explore the relationship between physical performance and visual acuity in university students in China. METHODS: tests of standing long jump, 50-meter dash and pull-ups sit-ups were conducted. The visual acuity was measured using a logarithm of the minimum angle of resolution (logMAR) chart. Pearson correlation was used to test the correlation of physical performance with visual acuity in university students. RESULTS: The number of pull-ups was negatively associated with visual acuity in the left eye for male students, while a negative correlation was found between the time of the 50-meter dash and visual acuity in the right eye for female students. CONCLUSIONS: Our study identified that physical exercise might help improve visual acuity. University students should practice strength exercises to improve physical performance.

Analysis of Psychological and Sleep Status and Exercise Rehabilitation of Front-Line Clinical Staff in the Fight Against COVID-19 in China.

BACKGROUND The aim of this study was to understand the changes in psychological factors and sleep status of front-line medical staff in the fight against COVID-19 and provide evidence of exercise interventions to relieve psychological stress and improve sleep status for medical staff. MATERIAL AND METHODS A survey study was conducted among 120 front-line medical staff in the fight against COVID-19, of which 60 medical staff worked at the designated hospital (experimental group) and 60 medical staff worked at the non-designated hospital (control group). The Symptom Checklist 90 (SCL-90), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and PTSD Checklist-Civilian Version (PCL-C) were used to assess mental status. Sleep status was assessed using the Pittsburgh Sleep Quality Index (PSQI). RESULTS SCL-90 scores of somatization, depression, anxiety, and terror were higher than normal in front-line medical staff at the designated hospital. The SAS (45.89±1.117), SDS (50.13±1.813), and PCL-C (50.13±1.813) scores in the experimental group were higher than the normal control group, and were significantly different from those in the control group on SDS and PCL-C scales (P<0.05). The total average PSQI of the experimental group was 16.07±3.761, indicating that the sleep quality was poor. Among them, participants with moderate insomnia reached 61.67%, and participants with severe insomnia reached 26.67%. CONCLUSIONS There are psychological symptoms and sleep symptoms in front-line medical staff who participate in the fight against COVID-19, and they affect each other. Hospitals should improve emergency management measures, strengthen psychological counseling for clinical front-line medical staff, strengthen exercise intervention, and improve their sleep quality and mental health.

RESUMO OBJETIVO O objetivo deste estudo é explorar a relação entre desempenho físico e acuidade visual em alunos universitários da China. MÉTODOS testes de salto em distância em pé, corrida de 50 metros, flexões e abdominais foram realizados. A acuidade visual foi medida através de um logaritmo do quadro de ângulo mínimo de resolução (logMAR). A correlação de Pearson foi utilizada para testar a correlação entre o desempenho físico e a acuidade visual em alunos universitários. RESULTADOS O número de flexões apresentou uma associação negativa com a acuidade visual do olho esquerdo em estudantes do sexo masculino e uma correlação negativa foi encontrada entre o tempo da corrida de 50 metros e a acuidade visual do olho direito em estudantes do sexo feminino. CONCLUSÃO O nosso estudo identificou que o exercício físico pode ajudar a aumentar a acuidade visual. Os estudantes universitários devem praticar musculação para melhorar o desempenho físico.
