| Abstract [eng] |
Scientific research demonstrates that the majority of adults and children are not sufficiently physically active, and even the existing level of physical activity keeps decreasing. Physical inactivity is one of the most important factors to directly contribute to numbers of overweight and obese. Obesity has a negative effect on almost all of the systems in the human body. However, there is a lack of studies that would objectively assess the links between functional fitness and physical activity in early adolescence. The aim of the work was to determine relationships between functional fitness and physical activity in 11-14 year old teenagers. Posture, physical capacity, physical activity and anthropometric data of 11-14 year old teenagers were assessed. It was found that in the early stages of adolescence, 22,2 % of teenagers fell in the low-level physical activity group, and 20,1 % of teenagers were either overweight or obese. Only every other teenager had good posture. Physical capacity indicators, posture and explosive leg power had statistically significant correlations with physical activity in early adolescence. Teenagers of low physical activity were less physically capable than teenagers in the moderate to vigorous physical activity group. Incorrect posture, weak leg power and weak abdominal muscle endurance were more frequent among teenagers of low physical activity. It was also found that balancing ability, explosive leg power and abdominal muscle endurance had a statistically significant correlation with body mass and body fat percentage in early adolescence. Overweight/obese teenagers were less physically active and demonstrated less physical capacity than teenagers of normal body mass. . |
