Nordic vs Blood Flow Restriction Nordic Exercise in Elite Female Pole Vaulters

Effects of Nordic Hamstring Exercise and Blood Flow Restriction-Assisted Nordic Hamstring Exercise on Hamstring Strength, Muscle Morphology and Functional Performance in Elite Adolescent Female Pole Vaulters: A Randomized Controlled Trial

Sponsor

Toros University

Enrollment

36 participants

Start Date

May 27, 2026

Study Type

INTERVENTIONAL

Conditions

Sports injury prevention Athletic Performance Muscle Strength Hamstring Adaptation

Summary

The purpose of this randomized controlled trial is to compare the effects of Nordic Hamstring Exercise (NHE) and Blood Flow Restriction-assisted Nordic Hamstring Exercise (BFR-NHE) on hamstring muscle strength, muscle morphology, and functional performance in elite adolescent female pole vaulters. Thirty-six athletes aged 12-18 years will be randomly assigned to a Nordic Hamstring Exercise group, a Blood Flow Restriction-assisted Nordic Hamstring Exercise group, or a control group. Intervention groups will participate in supervised exercise training three times per week for eight weeks, while the control group will continue routine sports training. Outcomes will be assessed before and after the intervention period.

Interventions

BEHAVIORALNordic Hamstring Exercise

Participants will perform a supervised Nordic Hamstring Exercise program three times per week for 8 weeks in addition to their routine pole vault training. The exercise program will be progressively increased according to participant tolerance and training progression.

BEHAVIORALBlood Flow Restriction-Assisted Nordic Hamstring Exercise

articipants will perform a supervised Nordic Hamstring Exercise program combined with individualized blood flow restriction training three times per week for 8 weeks in addition to their routine pole vault training. Blood flow restriction will be applied using pneumatic cuffs at a predetermined percentage of arterial occlusion pressure.
