Differences Between Long Distance Road Runners and Treadmill Runners in Achilles Tendon Structure

Recruiting

• Conditions: Achilles Tendon Injury

• Registration Number: NCT06294093
• Lead Sponsor: University of Haifa

Brief Summary

this study will investigate the structure of the Achilles tendon and functional tests in road runners compared to treadmill runners.

Detailed Description

Healthy runners (road and treadmill runners) who run regularly at least twice a week for half an hour, over 80% of the training on the treadmill or road, will be recruited for the study.

All subjects will fill out a demographic questionnaire for personal details (age, sex, height, weight, past injuries, training). Each participant will undergo functional tests in random order: 1. Examination of the morphology of the Achilles tendon - will be examined by ultrasound tissue characterized (UTC) 2. Balance test - Y Balance Test 3. Proprioception test - AMEDA device 4. Muscle strength test - manual dynamometer for testing gastrocnemius muscle strength. 5. Gastrocnemius muscle endurance test - single leg heel raise test until fatigue.

A comparison will be made between the two study groups.

Primary Outcome Measures

Name	Time	Method
endurance test gastrocnemius muscle	baseline	number of single leg heel raise test until fatigue
Balance test	baseline	Y Balance Test - composite score: sum of 3 reach directions in centimeters divided by 3 times the limb length then multiplied by 100
muscle strength test	baseline	hand held dynamometer dynamometer assessment of Gastrocnemius muscle
ultrasound tissue characterized	baseline	percentage of type 1,2,3,4 fibers within the tendon
Proprioception test	baseline	AMEDA device - scores between 0 and 1, A higher score represents better proprioception ability.
