Title

THE EFFECTS OF STATICS AND DYNAMICS STRETCHING ON COP DISPLACEMENT DURING QUIET STANDING IN ACTIVE HEALTHY YOUNG MALES

Abstract

 INTRODUCTION: STATIC AND DYNAMIC STRETCHING DONE BY RECREATIONAL AND PROFESSIONAL ATHLETES DURING WARM-UP ACTIVITIES, DESPITE LITTLE SCIENTIFIC EVIDENCE TO SUPPORT THE SUPERIORITY OF ONE PROTOCOL TO ANOTHER ONE (1). RECENTLY A NUMBER OF STUDIES HAVE SHOWN THAT STATIC STRETCHING MAY NOT BE EFFECTIVE IN PREVENTING INJURIES OR MAY TEMPORARILY REDUCE MUSCLE’S ABILITY TO GENERATE FORCE, WHILE SOME STUDIES HAVE SUGGESTED THAT PERFORMING DYNAMIC STRETCHING BEFORE EXERCISE CAN IMPROVE PERFORMANCE WITHOUT DEFICITS IN FORCE PRODUCTION (2). HOWEVER, THE EXAMINATION OF CENTER OF PRESSURE (COP) DISPLACEMENT AS A PARAMETER TO STUDY DYNAMIC POSTURAL CONTROL IN HUMANS, ESPECIALLY IN SPORTS ACTIVITIES AND SKILLS, HELPS TO IDENTIFY IMPORTANT ELEMENT VARIABLES WHICH HAVE ROLES IN IMPROVING PERFORMANCE AND DAMAGING FACTORS FOR THAT SKILLS. NOW THE QUESTION ARISES THAT CAN STATIC AND DYNAMIC STRETCHING HAVE DIFFERENT EFFECTS ON COP DISPLACEMENT? THE PURPOSE OF THIS RESEARCH WAS TO EXAMINE THE EFFECTS OF STATICS AND DYNAMICS STRETCHING ON COP DISPLACEMENT DURING QUIET STANDING IN ACTIVE HEALTHY YOUNG MALES.METHODOLOGY: 10 PHYSICAL EDUCATION AND SPORTS SCIENCES MALE STUDENTS VOLUNTARILY PARTICIPATED IN THIS RESEARCH. SUBJECTS REFERRED TO THE LABORATORY DURING TWO SESSIONS WITH 48 HOURS INTERVALS. IN EACH SESSION, THE COP DISPLACEMENT DATA DURING QUIET STANDING ON PREFERRED LEG WERE COLLECTED IN SITUATION OF WITHOUT STRETCHING AND AFTER STATIC AND DYNAMIC STRETCHING BY MEANS OF FORCE PLATE AT FREQUENCY OF 200 HZ FOR 20 SECOND. INFORMATION ABOUT COP TOTAL DISTANCE, COP DISPLACEMENT AND COP DISPLACEMENT VELOCITY WERE CALCULATED FOR EACH SUBJECT.RESULTS: THE RESULTS OF REPEATED MEASURE ANOVA SHOWED THAT THERE ARE SIGNIFICANT DIFFERENCES IN COP TOTAL DISTANCE AND COP DISPLACEMENT BETWEEN WITHOUT STRETCHING AND DYNAMIC STRETCHING SITUATION, AND BETWEEN STATIC STRETCHING AND DYNAMIC STRETCHING SITUATION. THE COP DISPLACEMENT VELOCITY HAS ALSO SIGNIFICANT DIFFERENCES BETWEEN STATIC AND DYNAMIC STRETCHING SITUATION.DISCUSSION: REGARDING RESULTS, PROBABLY STATIC STRETCHING CAN INCREASE POSTURAL SWAY AND CONSEQUENTLY DECREASE SUBJECT CONTROL TO MAINTAIN POSTURE. CONVERSELY, THE DYNAMIC STRETCHING CAN DECREASE COP SWAY AND CONSEQUENTLY INCREASE PERSON’S CONTROL TO MAINTAIN POSTURE. SO IT IS LIKELY THAT THE USE OF DYNAMIC STRETCHING IN PRE EXERCISES WARM-UP PROGRAMS RESULTS IN INCREASED BALANCE AND POSTURAL CONTROL AND THUS IMPROVES THE PERFORMANCE.
