L’ecografia B-mode (brightness mode) rappresenta oggi uno dei metodi più efficaci e non invasivi per visualizzare l’architettura muscolo-scheletrica, offrendo una panoramica dettagliata sugli adattamenti indotti dai processi di plasticità muscolare. Applicata alla performance sportiva, questa pratica consente di individuare le carenze muscolari dell’atleta, pianificare interventi mirati a prevenire infortuni e al miglioramento della prestazione. Permette inoltre di monitorare gli adattamenti muscolo-scheletrici, verificando l’efficacia del programma e, in ultima istanza, restituire all’atleta dei dati tangibili sulla sua condizione fisica, aumentando la fiducia e la sicurezza nell’affrontare allenamenti e competizioni. Questo progetto di tesi sperimentale si propone di confrontare diversi strumenti di imaging ecografico, al fine di individuare, tra quelli presi in considerazione, quello metodologicamente più appropriato alla corretta osservazione dell’architettura muscolare di ciascuno dei tre muscoli presi in analisi. Sono stati reclutati 22 soggetti, per ciascuno di essi, due operatori (OP1 e OP2) addestrati all’utilizzo dell’ecografo hanno misurato l’architettura dei muscoli vasto laterale (VL), gastrocnemio mediale (GM) e bicipite femorale (BF), con tre modalità di acquisizione differenti: SNAP 50% con sonda da 5 cm; EFOV con sonda da 5 cm e SNAP 50% con sonda da 10 cm. Dai dati ottenuti è stato possibile valutare i punti di forza e le carenze di ciascuna tecnica. Lo studio dunque, posizionandosi all’interno di una vasta e disomogenea letteratura scientifica, mira a chiarire quale possa essere lo strumento più adeguato, ad eseguire analisi efficaci e quanto più significative dell’architettura muscolare, considerando questa una base necessaria per la corretta valutazione dello stato di salute muscolo-scheletrica e per migliorare la performance sportiva negli atleti.
Stesso strumento, stessi risultati? Niente è come sembra: nuove prospettive metodologiche, cliniche e funzionali nell’analisi ecografica dell’architettura muscolare.

Abstract
B-mode (brightness mode) ultrasound is currently one of the most effective and non-invasive methods for visualizing the musculoskeletal architecture, offering a detailed overview of the adaptations induced by muscle plasticity processes. When applied to athletic performance, this technique makes it possible to identify an athlete’s muscular weaknesses, plan targeted interventions to prevent injuries, and improve performance. It also allows for the monitoring of musculoskeletal adaptations, verifying the effectiveness of the training program, and, ultimately, providing the athlete with tangible data on their physical condition, thereby increasing their confidence and assurance when facing training sessions and competitions. This experimental thesis project aims to compare different ultrasound imaging tools in order to identify, among those considered, the one that is methodologically most appropriate for the accurate observation of the muscle architecture of each of the three muscles under analysis. Twenty-two subjects were recruited; for each subject, two operators (OP1 and OP2) trained in the use of the ultrasound scanner measured the architecture of the vastus lateralis (VL), medial gastrocnemius (GM), and biceps femoris (BF) muscles using three different acquisition modes: SNAP 50% with a 5-cm probe; EFOV with a 5-cm probe; and SNAP 50% with a 10-cm probe. Based on the data obtained, it was possible to evaluate the strengths and limitations of each technique. This study, therefore, situated within a vast and diverse body of scientific literature, aims to clarify which tool may be the most appropriate for conducting effective and meaningful analyses of muscle architecture, considering this a necessary foundation for the proper assessment of musculoskeletal health and for improving athletic performance in athletes.| File | Dimensione | Formato | |
