Cardiovascular Autonomic Function After Resistance Training

2. september 2026 oppdatert av: Sungchul Huh, Pusan National University Yangsan Hospital

Effects of 8-Week Resistance Training on Cardiovascular Autonomic Function in Spinal Cord Injury

The purpose of this clinical trial is to evaluate whether an 8-week upper-limb resistance training program improves cardiovascular autonomic function in adults with chronic spinal cord injury (SCI). The primary objectives are to determine whether upper-limb resistance training improves heart rate variability (HRV) and baroreflex sensitivity (BRS), and whether it improves blood pressure responses during postural change, upper-limb strength, symptoms related to orthostatic hypotension, and quality of life.

Participants will be randomly assigned to either the resistance training group or the control group. All participants will complete assessments before and after the 8-week study period, including measurements of HRV, BRS, blood pressure responses during a tilt-table test, hand grip strength, and questionnaires assessing orthostatic hypotension symptoms and quality of life. Participants assigned to the resistance training group will participate in supervised upper-limb resistance training three times per week for 8 weeks.

Detaljert beskrivelse

SCI can impair cardiovascular autonomic function by disrupting the neural pathways that regulate heart rate and blood pressure. As a result, many individuals with SCI experience cardiovascular autonomic dysfunction, including orthostatic hypotension, which may increase cardiovascular health risks.

Although exercise is recommended for people with SCI, previous studies have mainly focused on aerobic exercise and have demonstrated inconsistent effects on cardiovascular autonomic function. Upper-limb resistance training is widely used in rehabilitation to improve strength and functional independence, but its effects on autonomic function have not been well established.

This randomized controlled trial will evaluate whether an 8-week upper-limb resistance training program improves cardiovascular autonomic function in adults with chronic SCI. The study will assess changes in HRV and BRS, while also exploring changes in orthostatic blood pressure responses, upper-limb strength, orthostatic hypotension symptoms, and quality of life. The findings may provide evidence supporting upper-limb resistance training as a rehabilitation strategy to improve cardiovascular autonomic function in individuals with chronic SCI.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Exercise group
Participants will receive a supervised upper-limb resistance training program three times per week for 8 weeks. The program consists of progressive resistance exercises for the upper extremities.
Atferdsmessig: Upper-Limb Resistance Training
Participants will perform a supervised upper-limb resistance training program three times per week for 8 weeks. Each session will last approximately 30 minutes and consist of progressive resistance exercises for the upper extremities. Exercise intensity will be progressively adjusted according to each participant's tolerance.
Ingen inngripen: Control group
Participants will continue their usual daily activities without participating in the resistance training program during the 8-week study period.

Tidsramme
Orthostatic Hypotension
Tidsramme: Baseline and Week 8
Orthostatic hypotension will be assessed by changes in systolic and diastolic blood pressure (ΔSBP and ΔDBP) during postural change using a tilt table. Orthostatic hypotension will be defined as a decrease in systolic blood pressure of ≥20 mmHg or diastolic blood pressure of ≥10 mmHg.
Baseline and Week 8
Grip Strength
Tidsramme: Baseline and Week 8
Grip strength will be measured using a hand dynamometer to evaluate changes in upper-limb muscle strength following the intervention.
Baseline and Week 8
Orthostatic Hypotension Symptoms (ADFSCI)
Tidsramme: Baseline and Week 8
Orthostatic hypotension-related symptoms will be assessed using the orthostatic hypotension items of the Autonomic Dysfunction Following Spinal Cord Injury (ADFSCI) questionnaire.
