System of impact factors on human movement

This lecture explores the aim and systemic approach of studying the impact factors on human movement, specifically in the context of sports science. The lecture discusses the limiting factors of athletes' performances and outlines a systematic determination of factors and relations. It also provides recommendations for constructing an impact factor system and includes examples and assignments for students to further explore the topic.

  1. System of impact factors on human movement The International Christmas Post-graduate School "Qualitative and Quantitative Research in Sport Science” 6-10th December 2006 Berzsenyi College – Szombathely Hungary Jan Novotný Dept. of Sport Medicine Faculty of Sports Studies Masaryk University Brno - Czech Republic novotny@fsps.muni.cz

  2. System of impact factors on human movement OUTLINES • Aim of the lecture • Limiting factors of athletes´ performances Supplement • Systemic approach to the scientific problems • What is the system of factors? • Systematic determination of factors and relations • Strings of factors and relations • Recommendation for the construction of the system • Example of student's impact factor system • Assignment for students to discussion

  3. System of impact factors on human movement Aim of the lecture and systemic approach SUPPORT OF RESEARCH PROJECTS planning – strategy and method selectionhypothesis construction - result interpretation - conclusions TO CONTRIBUTE TO SYSTEMIC SOLUTION OF COMPLICATED SCIENTIFIC PROBLEMS (Exercise of diabetics) TO ANSWER TO SCIENTIFIC QUESTIONS (What exercise intensity is optimal for diabetics?)

  5. System of impact factors on human movement Attributes of the systemic approach(P.Janíček, E. Ondráček, 1998) • Definition of terms, explication of the sense. • Analysis of a situation and problem. • Detection and description of objects, processes on, and relations among one. • Non-isolated evaluation of objects. • Complex hierarchical understanding and solution of a problem. • Object evaluation at time dependence. • Irreplaceability of human factor. • Final analysis and verification of the system.

  6. System of impact factors on human movement What is the system of factors? Diagram of a simplified example SYSTEM = SET OF FACTORS ELEMENTS VARIABLES AND RELATIONS STATE OF THE DIABETES control complications LEVEL OF ADAPTATION TO THE STRESS REACTION OF DIABETICS TO EXERCISE GENDER GENOTYPE ? EXERCISE Intensity, duration ... EXTERNAL CONDITIONS

  7. System of impact factors on human movement Systematic determination of the factors and relations To find and describe variables and relations among them - cause (independent factor) - consequence (dependent factor) - multiple cause - multiple consequence - reciprocal influence/impact To thinkabout weight of factor influence/impact(aim of research). MUSCLE CONTRACTIONS MENTAL STRESS GLYCAEMIA BLOOD PRESS

  8. System of impact factors on human movement A lot of „independent“ factors, dependent factor I If MOTIVATION isvery high andHEIGHT is 134 cm and HEART has EF>60% and KNEE has flexion 0-120othen ABILITY TO ADAPTED BASKETBAL is good.

  9. System of impact factors on human movement AIM OF SCIENCE = FIND UP STRINGS OF FACTORS AND RELATIONS HYPOTHESIS VERIFICATION NEW PIECE OF KNOWLEDGE - NEW TOOL FOR SOLUTION OF LIFE PROBLEMS MOTIVATION + HEIGHT + HEART + KNEE ABILITY TO BASKETBALL EF I H F H L I EXCELENT H L H F L I GOOD H H F L L I BAD L H - HIGH - LOW - FULL - IMPAIRMENT L F I

  10. System of impact factors on human movement Steps of the system construction(modification by P.Janíček and E. Ondráček, 1998) • DETERMINATION AND ANALYSIS OF OBJECT (Diabetic) • DETERMINATION, ANALYSIS AND FORMULATION OFPROBLEM (Exercise of diabetic) • FORMULATION OF AIMS FOR SOLUTION OF THE PROBLEM(To find an optimal exercise intensity for diabetics) • ANALYSIS AND DETERMINATION OF LIMITATION, URGENCY etc. OF THE PROBLEM (Number and compliance of patient, Financial conditions, Time, Personnel, Tradition, etc.) • SYNTHESIS OF THE SYSTEM - Detection and description of objects and relations (State of diabetes, Specific diabetic complications, Reaction to the exercise, Exercise – volume, intensity; Preferred exercises, Safety limit of exercise intensity)

  11. System of impact factors on human movement Recommendations for construction of the system? 1.INSPIRATION in an epicentre of selected scientific problem (REAL SYSTEM) - To watch objects during action(diabetic). - To talk with involved people(parents, doctor, teacher...). 2. INSPIRATION: - To study of literature sources (Current contents ...). - To consult with experts. - To use experience. TO ENRICH AND TUNE THE SYSTEM REPETITION 3. TO COLLECT FACTORS AND RELATIONS: TO DRAW A DIAGRAM (see next example) and TO DESCRIBE (ABSTRACT SYSTEM). 4. TO RECOGNIZE: - factors (aerobic capacity)→ definition, - indicators of the factors (VO2max) → what and why to measure, - type of values (quantitative - numerical - ml/kg.min) → howto measure

  12. System of impact factors on human movement Example of student's impact factor system How do a value orientation impact a gymnast's performance? (Jalovecká, 20 October 2006) Age Gender Mental type Motivation Effort Family Friends Somatotype Gymnast's performance Value orientation ? Press TV Physiological functions Training Regeneration Technical equipment Physical fitness pondered psychological study - cross-section - questionnaires

  13. System of impact factors on human movement Assignment for students Think up, draw, and describe factors and relations of your research problem in a diagramto next discussion. Orientation in a space and among factors is a important.

  14. System of impact factors on human movement CONCLUSIONS • The human movement is impacted by a lot of factors. • The research on the field needs a systemic approach. • The creation the factor system (diagram), and its systematic improving, supports a research project realization- planning – strategy and method selection – hypothesis construction - result interpretation – conclusions. 4. The creation of the factor system demands time. Hurried scientist don't notice simple reason of worse performance –athlete was late on the start. Start of triathlon in Brno 2006
