简要总结
This study investigated the effects of resistance training applied with a velocity-based approach on selected motor skills in university-level athletes. Participants were randomly assigned to two groups: a velocity-based training (VBT) group and a percentage-based training (PBT) group. Both groups performed lower-body resistance exercises over an 8-week period, three times per week. Pre- and post-training assessments were conducted for countermovement jump (CMJ), sprint (20 m and 40 m), agility (505 test), and one-repetition maximum (1RM) squat performance. The aim of this study was to compare the effects of VBT and PBT on jump, sprint, agility, and strength performance. It was hypothesized that the VBT group would show greater improvements in motor skills compared to the PBT group.
详细描述
This randomized, parallel-group, interventional trial was designed to examine the effects of resistance training performed using a velocity-based approach on selected motor skills among trained university athletes.
A total of 20 male participants (aged 18-30 years) were randomly assigned into two groups:
Velocity-Based Training (VBT) group: performed squats, lunges, and similar lower-body exercises using individualized movement velocity feedback obtained from a linear encoder.
Percentage-Based Training (PBT) group: performed the same exercises based on traditional fixed-load percentages of one-repetition maximum (1RM).
Both training programs lasted 8 weeks and included three sessions per week. Pre- and post-tests included measurements of countermovement jump (CMJ) height and power, sprint times (20 m and 40 m), agility (505 test), and maximal squat strength (1RM).

研究组 & 干预措施
Percentage-Based Training (PBT) Group
Participants in this group performed a resistance training program based on fixed percentages of their one-repetition maximum (1RM). The training load was adjusted weekly according to percentage-based progression over 8 weeks.
干预措施: Percentage-Based Training (PBT) (Behavioral)
Velocity-Based Training (VBT) Group
Participants in this group performed the same resistance training exercises as the PBT group, but the training load and volume were adjusted according to movement velocity feedback using a linear position transducer. The intervention lasted for 8 weeks.
干预措施: Velocity-Based Training (VBT) (Behavioral)
