Eccentric training via Nordic hamstring exercises (NHE) is effective in preventing hamstring strains by promoting changes in muscle structure, specifically increasing muscle fascicle length and adding sarcomeres in series within the muscle fibers.
In a study with 12 participants, after 9 weeks of NHE training, the biceps femoris long-head (BFlh) showed significant improvements, including a 19% and 33% increase in fascicle length in the central and distal regions, respectively, along with a 40% increase in knee flexion strength.
Following a 3-week period of no training (detraining), muscle adaptations such as fascicle length

The study was a randomized trial aimed at creating an algorithm for automatically segmenting spinal muscles in MRI images of healthy individuals and patients with adult spinal deformity (ASD).
Researchers imaged three groups (two healthy groups and one ASD group) and used a convolutional neural network to automate the segmentation process, evaluating its accuracy against manual segmentation.
The results showed strong accuracy in segmentation (Dice coefficients >0.76 for ASD and >0.86 for healthy groups), paving the way for easier access to patient-specific spinal muscle information for diagnosis and treatment.

Spine models are usually created from supine imaging data, which doesn't reflect the postures related to patients' symptoms; the study aims to improve this by estimating spine curvature in various positions from limited data.
The study involved scanning six healthy volunteers' thoracic spines in different postures using upright MRI, and developing methods to accurately estimate spine geometry and analyze muscle function (fascicle length) across those postures.
Results showed that muscle lengths could increase significantly in certain positions, and corrections were applied to muscle parameters based on the angle between scan planes and muscle fibers, leading to a better understanding of subject-specific modeling.

The study investigates how the morphology of thoracic muscles (trapezius, erector spinae, transversospinalis) differs between various postures (supine, standing, flexed, sitting) using open MRI technology.
Results show that muscle size varies significantly depending on posture and spinal level, such as the trapezius being smaller at T9 compared to T8 and the erector spinae being larger at T5 than T4.
The findings suggest that muscle morphology in the thorax is influenced by body position, which could have implications for diagnosing and treating spinal issues.

This study focuses on developing a new method to measure thoracic spinal muscle morphology using MRI, which is important for understanding spinal health and kyphosis severity in older adults.
Researchers imaged six healthy volunteers and created guidelines for identifying key muscles in the thoracic region, ensuring accuracy in measurements of muscle size and position.
The results showed high repeatability in muscle measurements between different raters, validating the methodology and enabling reliable comparisons in future spinal health research.
