简要总结
this study will investigate the structure of the Achilles tendon and functional tests in road runners compared to treadmill runners.
详细描述
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.

结局指标
主要结局
endurance test gastrocnemius muscle
时间窗: baseline
number of single leg heel raise test until fatigue
Balance test
时间窗: 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
时间窗: baseline
hand held dynamometer dynamometer assessment of Gastrocnemius muscle
ultrasound tissue characterized
时间窗: baseline
percentage of type 1,2,3,4 fibers within the tendon
Proprioception test
时间窗: baseline
AMEDA device - scores between 0 and 1, A higher score represents better proprioception ability.
