Abstract

Background and Study Aim: One of the elements of obesity therapy is increased physical activity. The WHO, determined the level of physical activity necessary to maintain good health at 60 minutes a day for children and 30 minutes of intense physical activity 5 times a week for adults The aim of the study is the knowledge about the suitability of the fat-non-fat indicator (FFF) to monitor changes in body composition under the influence of 10 weeks of kyokushin karate training in younger school children.

Materials and Methods: Seventy-seven children with normative body weight (N) and 76 with BMI above 85 percentile for age and sex (O – abnormal body weight) were qualified from 593 children examined for the research program. Body mass and body composition were determined in all subjects and on their basis the general and segment fat-free fat index (FFF) was calculated. Body composition was determined using Tanita's BC-418 MA 8-electrode body composition analyser. In individual groups, children were randomly selected to participate in NKKT (normative body weight kyokushin karate training) n = 30, OKKT (abnormal body weight kyokushin karate training) n = 29. The other children constituted the control group (48 girls; 46; boys). The subjects underwent a 10-week kyokushin karate training. After the training, comparative tests were carried out.

Results: Fat-free fat index was statistically significantly different between overweight children and normative body weight except for the upper limb in boys from the control group. After 10 weeks of training, a decrease in the FFF indicator in the training group and an increase in the control group were observed. Statistically significant changes were noted in the group of overweight boys kyokushin karate training.

Conclusions: Karate training is recommended for the group of younger children because it improves body posture and symmetry of fat distribution. The FFF index is a good tool for assessing the impact of training on changes in the level of the body composition components.
