Abstract:
Cardiovascular endurance has described the functions of the respiratory, cardiovascular, and musculoskeletal systems in carrying out physical activities. This is determined by measuring VO2 max. Physical activity will increase VO2 max value. Repetitive and systematic movements stimulate organ function to work optimally, characterized by increased the denser capillary filling to meet the needs of oxygen and nutrients for cells, including brain cells, makes cognitive abilities will be better. This research was conducted on 60 elementary school students. Subjects followed multistage fitness to determine their VO2 max and physical fitness levels. Then the subject participated in teaching and learning activities with the learning method. The results showed that physical fitness and achievement were directly proportional to the increase in fitness based on problems (PBM). The increase in physical fitness level will improve academic achievement.
