Slide2: 

THE AIM OF THE STUDY To explore a cluster structure of sport interests of elementary school children

Slide3: 

SUBJECTS 1294 urban elementary school pupils aged 11 -15 years (685 boys, 609 girls)

Slide4: 

VARIABLES Measure of sport preferences - list of 52 sports to be evaluated on five-point scale to describe intentios of behaviour

Slide5: 

The list of 52 sports: acrobatics, aerobics, aeronautics, rock climbing, archery, athletics, auto-moto sports, badminton, baseball, basketball, bodybuilding, bowls, boxing, canoeing, cycling, dance, diving, equestrian, fencing, field hockey, football, handball, ice hockey, judo, karate, mountaineering, orienteering, parachuting, pin bowling, rhythmic gymnastics, roller skating, rowing, rugby, schooting, scuba diving, skating, skiing, sledging, spear-fishing, sports fishing, sports gymnastics, surfing, swimming, synchronized swimming, table tennis, taekwondo, tennis, volleyball, water skiing, waterpolo, weightlifting and wrestling.

Slide6: 

- I will never participate - I will participate only if there it will be no other activity - I will participate from time to time temporarily, but, under suitable conditions - I would like to participate - I would participate just if there it will be any oportunity Five-point scale:

Slide7: 

METHODS Groups were defined as five distinct clusters obtained by SPSS implementation of k-means clustering of sport preference scale results.

RESULTS

Slide9: 

subjects preferring sports with marked aesthetic component, some sports on water and equestrian, and rejecting the number of "male" sports. subjects preferring dance, tennis, roller-skating and badminton, and rejecting "male" sports. subjects with above average values of preferences on all sports. subjects with marked above average interests in football, ice hockey, rowing, shooting and motor-sport, and evident under average interests in dance, aerobics, synchronized swimming and rhythmic gymnastics. subjects preferring football and basketball, being neutral to tennis, table tennis, handball, cycling and motor-sport, and rejecting all the other sports

Slide10: 

subjects preferring sports with marked aesthetic component, some sports on water and equestrian, and rejecting the number of "male" sports. N1 = 251

Slide11: 

2. subjects preferring dance, tennis, roller-skating and badminton, and rejecting "male" sports. N2 = 220

Slide12: 

3. subjects with above average values of preferences on all sports. N3 = 214

Slide13: 

4. subjects with marked above average interests in football, ice hockey, rowing, shooting and motor-sport, and evident under average interests in dance, aerobics, synchronized swimming and rhythmic gymnastics. N4 = 369

Slide14: 

5. subjects preferring football and basketball, being neutral to tennis, table tennis, handball, cycling and motor-sport, and rejecting all the other sports N5 = 240

Slide15: 

WHY IT IS SO?

Slide16: 

Prot, Bosnar and Sporiš (2006) Samples representative for seccondary school graduates 3327 males and 3106 fenales Urban adolescents of average age 18.3 years

Slide17: 

Centoids on discriminanat functions

Slide21: 

Discriminant analysis in space of 52 sport interest preferences with respect to gender: r = 0.837 Discriminant analysis in the space of discriminant scores of k-means clusters with respect to gender: r = 0.811 - Correlation of discriminant scores from step 1. and step 2. : r = 0.969 Aditional analyses and results:
