Tokyo, April 28 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061386) titled 'Development of efficient running patterns based on muscle structural and metabolic characteristics' on April 27.

Study Type: Interventional

Study Design: Basic Design - Single arm Randomization - Non-randomized Blinding - Open -no one is blinded Control - Uncontrolled

Primary Sponsor: Institute - Ritsumeikan University

Condition: Condition - Healthy adults Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The purpose of this study is to clarify the relationship between muscle structural and metabolic characteristics and running biomechanics, and to identify the factors that determine individually optimal and efficient running patterns. Basic objectives2 - Others

Intervention: Interventions/Control_1 - Participants undergo measurements of lower-limb muscle morphological and metabolic characteristics using MRI, followed by treadmill running at fixed speeds. During running, running economy and biomechanics are assessed using respiratory gas analysis and motion capture.

Eligibility: Age-lower limit - 18 years-old = Gender - Male and Female Key inclusion criteria - Participants will include 30 male and female endurance runners aged 18-30 years who have achieved a personal best marathon time within the past year of under 4 hours for males and under 4 hours 30 minutes for females, or who have achieved an equivalent performance level based on the World Athletics (WA) scoring system using race distances of 5 km or longer. The corresponding WA scores are 54 points for males and 259 points for females. In addition, 30 healthy male and female adults aged 18-30 years who do not engage in running more than twice per week will also be included. Key exclusion criteria - -Individuals who do not meet the specified age range. -Endurance runners who have not performed long-distance running (3 km or more per session, 2 times or more per week) within the past 6 months. -Individuals with a history of Achilles tendon rupture or anterior cruciate ligament injury within the past 6 months, or those currently restricted from exercise by a physician. -Individuals currently undergoing treatment for injury or illness. -Individuals with mental or physical impairments (psychiatric or visual disorders) that may interfere with study participation. -Individuals requiring assistive devices for daily activities due to injury or disability. -Individuals experiencing pain that prevents comfortable execution of the running tasks specified in this study. -Individuals with a history of claustrophobia or panic disorder. -Individuals unable to remain still during measurements. Pregnant individuals. -Individuals with a history of epileptic seizures. -Individuals with implanted medical devices such as cardiac pacemakers, defibrillators, or artificial heart valves. -Individuals with metal in the body (orthodontic appliances, dental prostheses, depending on material, surgical clips, etc.). -Individuals with tattoos (due to potential interaction with magnetic fields). Target Size - 60

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 07 Month 01 Day Anticipated trial start date - 2029 Year 03 Month 01 Day Last follow-up date - 2029 Year 03 Month 31 Day
