Transcript of "The evaluation of hand grip strength among badminton"

  1. 1. THE EVALUATION OF HAND GRIP STRENGTH AMONG BADMINTON AND TABLE TENNIS PLAYERS PREPARED BY WAN HAFIZI WAN KAMALUDIN1 HERMIZAN HALIHANAFIAH
  2. 2. INTRODUCTION Motor skills can be defined as a activity or task that has a specific purpose or goal to achieve. One of the motor skills in racquet sports is hand grip strength. These hand grip strength requires flexor musculature of the forearm and also hand. These motor skills plays as a key role in injury prevention and overall strength development (Budoff, 2004; Fry et al, 2006; Smith et al, 2006; Yasuo et al, 2 2005)
  3. 3. PURPOSE OF THE STUDY There are a lot of anthropometric and hand grip strength studies in sports activities. Many researcher evaluate more on the gross anthropometrics measurement such as BMI, arm circumference, skin folds, arm length and etc. So the purpose of this study to evaluate the differences in hand grip strength among badminton and table tennis players. 3
  4. 4. HYPOTHESIS Null hypothesis - There is no significant different in hand grip strength between badminton and table tennis sports Alternative hypothesis- There is significant different in hand grip strength between badminton and table tennis sports 4
  5. 5. METHOD 5
  6. 6. SAMPLE SELECTION Based on demographic data, 10 male badminton players (n=10) and 15 male table tennis players (n=10) age between 25-30 are selected from Kolej Mara Banting (n=25). Exclusion criteria were set (genetic, physiological, neurological and chronic disease) because it might be affecting the anthropometric measurements (Malina & Buschang, 1984; Brill & Stier, 1999) 6
  7. 7. MEASURING METHOD Maximal hand grip strength (HGS) ) has been used for as a method for assessing muscles strength and functions (Bohannon, 2008). A digital hand dynamometer (Takei, Japan) was used to measure the hand grip strength. The subject will sit on a chair with the elbow flexed at 90 degrees and the forearm in semipronation (neutral position) lying on an arm rest. (Kuzala & Vargo, 1992) 7
  8. 8. MEASURING METHOD The subjects were asked to squeeze the dynamometer three times by using dominant hand. There was a one minute resting period between each squeeze in order to overcome the fatigue. The mean value of three squeezes was taken into account (Hager-Ross & Rosblad, 2002). 8

  15. 15. STATISTICAL ANALYSIS Test Purpose To ensure the collecting data has normal Shapiro Wilk distributionIndependent T Test To make comparison between two groups 15
  16. 16. STATISTICAL ANALYSIS •Independent T Test n Mean (SD) Mean t value (df) P value differenceTable tennis 15 37.6 (5.76) 1.60 -0.776 (23) 0.446Badminton 10 39.2 (3.67)*data is normal distributed and variance was equal between the groups 16
  17. 17. FINDING AND DISCUSSION The P value is more than 0.05. We fail to reject the null hypothesis, therefore there is no significant difference hand grip strength between table tennis and badminton player group. 17
  18. 18. FINDING AND DISCUSSION The non significant result may be due small sample size (n=25). We can see the badminton players value is higher compare to table tennis players. The difference about 1.60 (badminton high about 1.6 compare to table tennis player). Sample size calculation for further study is like below which is 54 per group. 18
  19. 19. CONCLUSIONBased on statistical analysis: Hand grip strength played a vital role in racquet sports (badminton, tennis, table tennis) In this study we believed, there are difference in grip strength among different type of racquet sports. (due to differ in efficacious usage of hands) We suggested that for further study, hand grip strength and hand anthropometric measurement (hand breadth, hand length, hand circumference) 19 should be included.
