Effects of strength training and jatamansi on reducing hand tremor amongst archers

ABSTRACT

To investigate and compare the effects of strength training (Shoulder girdle and respiratory muscles) and drug (Jatamansi) on reducing hand tremor in archers. Randomized experimental, different subject design. Institutional study done at Manipur Archery Association. Thera-band (Hygienic Corporation) and Nardostachys jatamansi (GMP Certified) were used as interventions. Pre & Post Hand Steadiness Score (Arm-Hand-Steadiness Tester on 4 mm hole) and Performance Test Scores (AAPHER Archery Test) was evaluated. 45 National Level Archers within age 16-28yrs were assigned into three groups Group I (Medicine), Group II (Strength Training) and Group III (Control). Medicine was consumed for 4 weeks continuously 3 gm TDS and Thera-band strength training was given for 3 times weekly for 4 weeks. Main Outcome Measures: It was hypothesized that strength training is more effective in reducing hand tremors than medicinal or control groups. Arm-Hand-Steadiness Numbers of Contact (NOC) On inter Group Comparison of the three Groups using One Way ANOVA, left and right arm showed significant differences (F = 5.64, p<0.05; F = 8.97, p<0.001) respectively and on Post Hoc Scheffe’s analysis, Group II showed maximum improvement. Total Contact Time (TCT) On inter Group comparison of the three Groups using One Way ANOVA, left and right arm showed significant differences (F = 12.50, p<0.001; F = 9.23, p<0.001) respectively and On Post Hoc Scheffe’s analysis, Group II showed maximum improvement. Archery Performance On inter Group comparison of the three Groups using One Way ANOVA showed significant difference (F = 6.53, p<0.005) and on Post Hoc Scheffe’s analysis, Group II showed maximum improvement. Intervention of strength training and jatamansi may be effective for an archer however, strength training with thera-band and respiratory muscles conditioning intervention in combination increases steadiness and archery performance.
