Article Synopsis
- - The study examined how resistance exercise affects muscle structure and organization in the gastrocnemius medialis muscle by measuring muscle thickness, pennation angle, and fascicle length in healthy adults during rest and isometric contractions.
- - Key findings showed that muscle thickness and fascicle length increased after resistance exercise, while the pennation angle decreased, indicating significant changes in muscle architecture following exercise.
- - Spatial frequency analysis revealed that tissue organization metrics improved shortly after exercise but returned to baseline within 15 minutes, suggesting this method can help detect early physiological changes in muscle micro-structure.
Article Synopsis
- * Results showed that while FC scans generally produced lower muscle thickness measurements (decreasing by 2-3 mm), the intrarater reliability of muscle measurements was variable, with some methods demonstrating good to excellent reproducibility on repositioned scans.
- * The conclusion highlights that although the foam cast method provides more consistent results for certain measurements, it also shows variability in muscle architecture assessments and organization, which can affect data reliability.
Introduction: The purpose of this study was to investigate inter- and intra-rater reliability as well as the inter-rater interpretation error of ultrasound measurements assessing skeletal muscle architecture and tissue organization of the gastrocnemius medialis (GM) and vastus lateralis (VL) muscle.
Methods: The GM and VL of 13 healthy adults (22 ± 3 years) were examined thrice with sagittal B-mode ultrasound: intraday test-retest examination by one investigator (intra-rater) and separate examinations by two investigators (inter-rater). Additionally, images from one investigator were analysed by two interpretators (interpretation error).
Strength training is an important means for performance development in young rowers. The purpose of this study was to examine the effects of a 9-week equal volume heavy-resistance strength training (HRST) versus strength endurance training (SET) in addition to regular rowing training on primary (e.g.
