Investigating the Effects of a High-Load Resistance Training Program on Bone Health in Wheelchair Users (the...

Area of Science:

• Exercise Science
• Bone Physiology
• Rehabilitation Medicine

Background:

• Wheelchair users experience low bone mineral density (BMD) due to reduced mechanical loading, increasing fracture risk.
• High-load resistance training and adequate nutrition (vitamin D, calcium) are crucial for bone health in this population.

Purpose of the Study:

• To evaluate the impact of 24 weeks of high-load resistance training plus nutrition optimization on lumbar spine BMD in wheelchair users.
• To assess secondary effects on bone turnover markers, nutritional status, body composition, muscular strength, exercise motivation, and mental health.

Main Methods:

• A 24-week randomized controlled trial involving 60 wheelchair users with nonprogressive impairments.
• Intervention groups: high-load resistance training + nutrition optimization vs. nutrition optimization alone.
• Assessments included BMD, body composition, strength, and health parameters at baseline, midpoint, and post-intervention.

Main Results:

• 45 participants were enrolled (24 training, 21 control); data analysis is ongoing.
• Midpoint and post-intervention assessments were completed by 36 and 33 participants, respectively.
• Full results publication is anticipated by the end of 2025.

Conclusions:

• This is the first randomized controlled trial examining high-load resistance training in wheelchair users, focusing on bone, physical, and mental health.
• The study will provide novel data on exercise interventions for improving health outcomes in wheelchair users.
• Findings are expected to inform future research and clinical practice for this population.
