The Comparison of Combination of 8 Weeks of Resistance Training with Blood Flow Restriction and Traditional Resistance Training Based on Linear and Undulating Periodization on Hypertrophy, Strength, Muscular Endurance and Explosive Power in Active Girls

Most studies have commonly utilized traditional resistance training in training periodization and the effect of resistance training with blood flow restriction is not perfectly clear in this periodization. Therefore, the aim of this study was to compare the combination of eight weeks of resistance training with blood flow restriction and traditional resistance training based on linear and undulating periodization on hypertrophy, strength, muscular endurance and power in active girls. 26 active girls were randomly assigned to three groups: resistance training with no periodization, linear periodization and undulating periodization. Traditional strength training (TST) was performed with the intensity of 75% 1RM and blood flow restriction training (BFRT) was performed with the intensity of 30% 1RM. In linear periodization group, subjects performed BFRT during the first 4 weeks and TST during the second 4 weeks. In undulating periodization group, participants switched from BFRT to TST every session. The non-periodization group performed TST with constant intensity. For analyzing the data, one-way ANOVA was used. The results showed a significant increase in all groups from pretest to posttest for rectus femoris and vastus medialis cross sections, strength and endurance of quadriceps and hamstring and explosive power of legs. There was no significant difference among the groups in no variables except for vastus intermedius cross section. Combination of BFRT and TST in the form of linear or undulating periodization and non-periodization resistance training have both similar effects on hypertrophy, strength, endurance and explosive power of legs in active girls.
