Elastographic Measurement of Strain Ratio in Finger Tendons of Weight Lifters and Non-Weight Lifters

Abstract

This study aimed to determine the difference in stiffness and thickness of finger tendons between individuals who performed weight lifting (trained subjects) and those who did not perform weightlifting (untrained subjects) as well as provide real-time diagnosis of tendon stiffness. The study was divided into two groups according to their physical activity level. Individuals who performed training for their upper body for a minimum of 30 minutes, 5 days a week for at least 6 months were categorized as trained individuals, whereas those who did not train were categorized as untrained individuals. Tendon strain ratio and thickness of the index and middle fingers and body mass index (BMI) of trained and untrained adult males were measured. A total of 20 healthy individuals were enrolled for the study. Untrained individuals tended to have higher strain ratios than trained individuals. Tendon thickness between the groups was slightly different. Increased BMI was found in untrained individuals. Trained individuals had stiffer finger tendons than untrained individuals. Different activities, sedentary lifestyles or lifting weight can substantially affect the properties and size of the tendon, which can lead to strengthening or weakening of the finger tendon.
