What does it measure?

All primary and secondary schools in Slovenia are organising SLOfit measurements every April, using the same test battery.

  Measurement task Description
Physical dimensions of the body Body height Longitudinal dimension of the body
Body weight  Voluminous dimension of the body 
Tricpes skinfold  Assessment of peripheral fat 
Physical efficiency-related physical fitness   600-meter run General aerobic endurance  
Sit-ups Repetitive strength
Stand and reach  Flexibility of lower back and legs 
Bent arm-hang Isotonic strength
Arm plate tapping Repetitive speed
Standing long jump Explosive strength 
Polygon backwards Coordination
60-meter dash Speed

Physical development of children and youth is monitored through somatic growth, defined by body height, weight and triceps skinfold. Nutrition status is assessed through body mass index (BMI), which is calculated form height and weight. Individuals can be divided into different classes of nutritional status: undernutrition, normal nutritional status, overweight and obesity. Triceps skinfold is the anthropometric indicator of peripheral fat distribution. Children with high BMI and thick skinfold are exposed to major health risks.

Motor development is monitored through the development of various motor abilities. Indicators of the health-related fitness are aerobic capacity, muscular strength, muscular endurance and flexibility. Risk of heart disease, diabetes and stroke are reduced by highly developed aerobic abilities and properly developed flexibility. Muscular strength and muscular endurance are important for injury prevention and overall functioning of the body. Indicators with physical efficiency-related fitness are speed, explosive strength and body coordination and are generally not directly linked reduction of cardiovascular and metabolic risks but have considerably protective function, which enable fast and coordinated response in the event of overcoming unexpected obstacles during movements and falls.

Motor abilities are in primary and secondary school measured with 8 different motoric tasks (link na>Be fit, get into SLOfit): 20 second arm plate tapping, standing broad jump, polygon backwards, 60 seconds sit-ups, stand and reach, bent arm hang, 60m dash and 600m run. Based on the results we can index physical efficiency of the individuals, which tells us their position related to the population.

Why every year the same measurement procedure?

SLOfit measurement procedure is the same every year in primary and secondary school curriculum, which allows us a direct comparison of individual outcomes of physical and motoric development from 6 to 18 years of age. Selection of the appropriate tests was carried out carefully with the help of pilot and experimental study. Tasks are selected carefully taking into account relevant dimensional characteristics (validity and reliability) for selected age of children and youth.
