2. Physical activity (PA) “Physical activity is defined as any bodily movement produced by skeletal muscles that results in energy expenditure.” (Caspersen, Powell, & Christenson, 1985) Type, duration, frequency, intensity Objective & subjective 2

3. Physical fitness (PF) “the ability to carry out daily tasks with vigor and alertness without undue fatigue and with ample energy to enjoy leisure-time pursuits and to meet unforeseen emergencies.” (Caspersen, Powell, & Christenson, 1985) Health-related – Cardiovascular, muscle power, muscle endurance, flexibility Skill-related 3

4. Quality of life (QoL) Multidimensional construct defined as physical health, psychological state, personal belief, and social relationships; it reflects one’s self-perception of expectations and concerns in the context of the culture and its value systems (WHO, 1993) QoL instrument for children: child & parent reports 4

5. PA, PF, & QoL PA & PF PA & QoL PF & QoL 5

6. Methods 36 boys (9.16±.74 years) – Push-up – Sit-up – Sit and reach – 20-m shuttle run – Quality of life instrument: PedsQL One of boys’ parents – PedsQL 6

7. Methods PedsQL – Physical functioning – Emotional functioning – Social functioning – School functioning Composite score of 4 PF tests Pearson correlation coefficient 7

8. Results child-reported PedsQL (n=36) parent-reported PedsQL (n=34) rprp Total QoL 0.297*0.0410.2540.077 Physical 0.302*0.0390.324*0.033 Psychosocial 0.2520.0720.1690.174 Emotional 0.1530.1900.0350.423 Social 0.312*0.0340.296*0.047 School 0.1350.2200.0440.403 8 QoL=quality of life *p<.05

9. Conclusion In addition to PA, PF seems to be another important factor related to a boy’s QoL PA ↑ → Health condition/ QoL↑ PF↑ → QoL↑ – Physical & social functioning If a boy has his PF better, he can interact with his peers better → Girls ?? 9
