Abstract:The development of mathematical learning models based on Pepro Kreasi at junior high boarding school. This study aims to develop instructional mathematics models based on Pepro Kreasi (Knowledge, Processes, Creativity, Activity, and Attitude)

Introduction: Covid-19 survivors often complain of fatigue, cough, shortness of breath, fever, dermatitis, headache and so on. This decrease then has an impact on changes in cardiorespiratory fitness. Objective: Determine the level of cardiorespiratory fitness in Covid-19 survivors. Method: This study used a cross sectional design. The population of this study is Covid-19 survivors in Makassar City. Sampling using purposive sampling technique with a sample of 385 people. Data collection was carried out by taking primary data through measuring cardiorespiratory fitness levels using the Six Minute Walk Test (6MWT). Results: A total of 236 people (61.3%) Covid-19 survivors had a low level of cardiorespiratory fitness with an average distance value of 507.6 meters. Conclusion: Respondents who come from the adolescent age group, have a normal BMI, high activity, asymptomatic and mild symptoms, and a phase of chronic Covid-19 infection tend to have a good level of cardiorespiratory fitness. While most respondents from the elderly age group, have obese and obese BMI, work as medical personnel with low physical activity, accompanied by comorbidities and the acute Covid-19 infection phase have a low level of cardiorespiratory fitness.
