Evaluating results with percentiles
We calculate percentile value for for every SLOfit measurement which gives us information on the position of the result on the age and sex specific scale from 1 to 100. In this way we can directly compare the percentile values of tests with otherwise different units.
- Percentile value 50 means that the result equals the national mean. .
- 60th percentile means that the achieved result is better than the result of the 60% of population
We have established health risk zones for the results of individual tests:
- Height, body mass and triceps skinfold do not have healthy zones.
- The results of BMI are divided in 4 different zones:
- Yellow: SLIM
- Greem: EXPECTED / APPROPRIATE
- Orange: PREOBESE
- Red: OBESE
- Results of all 8 fitness tests are divided in 3 health-risk zones:
- Green: LOW RISK, HEALTHYO
- Yellow: MODERATE RISK, NEEDS IMPROVEMENT
- Red: HIGH RISK – NEEDS IMPROVEMENT
Presentation of longitudinal results in individual motor ability or physical dimension brings evidence on the trends in physical and motor development and identifies the problematic areas that have to be dealt with to ensure optimal development of a child.
Higher percentile in 600m run, 60m dash and polygon backwards are inverted and presents poorer result. Finishing 600m run in 155 seconds is thus ranked with higher percentile than finishing the same distance in 165 second. When you grow your body mass changes as well and you have to constantly adapt to your new body. This is why your results might fluctuate in comparison to your peers.
In the chart below we can observe the development of aerobic endurance of an overweight boy during primary school:
- In the first grade the boy was in the increased health risk zone according to his aerobic endurance and his situation further worsened since he started approaching the high health risk zone after age 11 and finally entered it at age 14.
- At age 11 the boy experienced accelerated growth and entered puberty but this was obviously accompanied with the decline in his physical activity. Consequently, his body mass started increasing at a much higher rate than his stature.
- If the boy increased his physical activity at that age he would be able to turn the trends in opposite direction, improve his health outlooks in adulthood, and increase his quality of life because his body would allow him to successfully take up leisure sports activities which he is currently not able to do.
The chart shows the development of the 600m run results of an overweight boy.
Colours mark different health risk zones:
green - healthy, yellow - moderate risk, red - hight risk, needs improvement.
