Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

The study was approved by the Istanbul Gelişim University Rectorate Ethics Committee (Approval No: 2024-01-144, Date: 12.01.2024) and conducted in accordance with the Declaration of Helsinki. All participants provided written informed consent prior to participation.

The primary outcome of interest was the change in CMJ performance. Secondary outcomes included sprint, agility, and 1RM strength improvements.

The results are expected to contribute to the understanding of how velocity-based resistance training affects neuromuscular adaptations and physical performance in athletes compared to traditional percentage-based training methods.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The study employed a parallel-group, randomized design. Participants were randomly assigned to either a percentage-based training (PBT) group or a velocity-based training (VBT) group. Both groups performed resistance training programs for 8 weeks, focusing on lower-body and upper-body exercises. The VBT group trained according to movement velocity feedback, while the PBT group followed loads based on fixed percentages of one-repetition maximum (1RM). Pre- and post-tests were conducted to evaluate changes in motor performance variables such as jump height, sprint time, and maximal strength.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Velocity-Based Training (VBT)

Intervention Type BEHAVIORAL

The velocity-based training (VBT) group performed lower-body resistance exercises for 8 weeks, three sessions per week. Training loads were adjusted based on real-time barbell velocity feedback measured with a linear encoder. Exercises included squats, lunges, and other multi-joint movements. Each session focused on maintaining optimal movement speed for power development.

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.

Group Type EXPERIMENTAL

Percentage-Based Training (PBT)

Intervention Type BEHAVIORAL

The percentage-based training (PBT) group performed the same resistance exercises as the VBT group for 8 weeks, three sessions per week. Training loads were prescribed according to a fixed percentage of each participant's one-repetition maximum (1RM). Exercises included squats, lunges, and other lower-body movements aimed at improving strength and power.
