Statistical calculations using the t-test. Hypothesis analysis using pre-test data and post-test data on the results of soccer shooting where the t-count analysis results obtained were 5. 231 then the value was compared with the ttable value with dk = n-1 (10-1 = 9) at a significant level α = 0.05 is 1.8331 thus t-count> ttable (5. 231> 1.8331). This means that Ho is rejected and Ha is accepted, it can be concluded that there is a significant influence of Shooting Exercise Variations on Shooting Results in Athletes aged 14-17 years at SSB Garuda II Langkat Regency Year 2022.
