Abstract

This study aimed to compare the effects of resistance or high-intensity interval training on sprinting, agility, and vertical jumping. Participants included 32 female high school soccer players who were randomly assigned to one of two groups: resistance training group (RTG, n=16, age: 16.25 ± 1.83 years, height: 164.95 ± 4.22 cm, body mass: 57.21 ± 5.28 kg, BMI: 21.36 ± 1.34 kg•m-2 ) or high-intensity interval training group (HIITG, n=16, age: 16.06 ± 1.48 years, height: 163.98 ± 7.60 cm, body mass: 57.63 ± 6.51 kg, BMI: 21.73 ± 1.75 kg•m-2 ). Pre- and post-testing included a 36.5-meter sprint, countermovement jump, and the Illinois agility test. The participants completed an eight-week training regimen for their respective groups, training three days per week, one hour for each session. The 36.5-meter sprint time was improved in both groups, with no significant difference between the RTG and HIITG (-0.18 ± 0.13 vs. -0.16 ± 0.16 s, p= 0.686). CMJ performance was improved in both groups, but the improvement was significantly greater for the HIITG than RTG (6.39 ± 3.10 vs. 1.19 ± 2.71 cm, p<0.0001). There was also a significant difference between the two groups in the change in time to complete the agility test (p=0.009). The RT group had a mean change of -0.75 ± 0.89 seconds while the HIIT group had a mean change of –1.76 ± 1.15 seconds. In conclusion, this study has shown that an 8-week pre-season period of training results in improvements on speed, power, and agility in both groups, with HIIT group showing superior adaptations in CMJ and agility than RT. However, there were no differences between the groups in change of sprint time.
