Objectives: To investigate and compare the effects of strength training (Shoulder girdle and respiratory muscles) and drug (Jatamansi) on reducing hand tremor in archers. Design: Randomized experimental, different subject design. Setting: Institutional study done at Manipur Archery Association. Interventions: 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. Results: 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. Conclusion: 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.
