Figure Legend Snippet: Schematic representation of the study protocol. The assessments of muscle damage markers and muscle hardness in the dominant and non-dominant arm were conducted sequentially as shown in the “Measurements” that consisted of maximal voluntary isometric contraction force (MVIC), push-in meter (PM), strain elastography (SE), relaxed, extended and flexed elbow angle (Elbow angles), upper arm circumference (CIR) and visual analog scale (VAS) for muscle soreness, before (Pre) and 1–4 days after exercise (Day 1- Day 4). After the Pre assessments, concentric (CON) and eccentric contractions (ECC) were performed by the dominant and non-dominant arm, respectively.
Techniques Used:
Figure Legend Snippet: Muscle hardness assessment. Biceps brachii muscle hardness of both arms was assessed by a push-in meter (PM) and strain elastography (SE) simultaneously. In this example, SE for the right arm, and PM for the left arm. (Microsoft Powerpoint 2019, https://www.microsoft.com/ja-jp/microsoft-365/powerpoint ).
Techniques Used:
Figure Legend Snippet: Typical examples of the force displacement relationships measured by push-in meter (PM, upper) and elastography images obtained by strain elastography (SE, lower) for biceps brachii (BB) muscle hardness assessment at before, 2 and 4 days after eccentric exercise. In PM, the force displacement relationship was divided into the subcutaneous area ( a ) and BB area ( b ), then muscle hardness value E was calculated using the slope (Km) of the force curve ranged in 0–35% BB thickness (from c to d ). In SE, the region of interest (ROI) was set for acoustic coupler area ( e ) and a circle including the whole BB ( f ). Using a built-in software, strain ratio (SR) was calculated for each image as a ratio of strain of the muscle ( f ) divided by the strain of the acoustic coupler (e), then SR was converted to Young’s Modulus from the known Young’s modulus of the coupler (22.6 kPa) by the formula; 22.6/SR. (Microsoft Powerpoint 2019, https://www.microsoft.com/ja-jp/microsoft-365/powerpoint ).

Figure Legend Snippet: Normalized changes (mean ± SD) in muscle hardness measured by push-in meter (PM, A ) and strain elastography (SE, B ) before (Pre) and 1–4 day after exercise. A significant interaction effect was found between eccentric (ECC) and concentric (CON) conditions for changes in PM ( p < 0.05) and USE ( p < 0.01). * shows a significant (p < 0.05) difference from the baseline value.
Techniques Used:
Figure Legend Snippet: Relationship between normalized muscle hardness assessed by push-in meter (PM) and that by strain elastography (SE). A significant correlation was evident (r = 0.752, p < 0.001, regression equation: y = 0.5x + 74.0).
Techniques Used:
Figure Legend Snippet: Relationship between muscle damage variables (maximal voluntary isometric contraction (MVIC) force, circumference (CIR), relaxed elbow angle (RANG) and extended elbow angle (EANG)) and muscle hardness assessed by push-in meter (PM) and strain elastography (SE). A significant (p < 0.001) correlation was evident between MVIC and PM (r = − 0.565, A ), MVIC and SE (r = − 0.516, E ), CIR and PM (r = 0.692, B ), CIR and SE (r = 0.518, F ), RANG and PM (r = − 0.772, C ), RANG and SE (r = − 0.745, G ), EANG and PM (r = − 0.548, D ) and EANG and SE (r = − 0.575, H ).

Diagnostic Assay:Article Title: Tracking of Time-Dependent Changes in Muscle Hardness After a Full Marathon Article Snippet: 1 We sought to identify changes in individual muscle hardness after a full marathon and 2 to track time-dependent changes using ultrasound strain elastography (SE).. Twenty-one 3 collegiate marathon runners were recruited.. Muscle hardness (i.e., strain ratio, SR) was 4 measured using SE for the rectus femoris (RF), vastus lateralis (VL), biceps femoris 5 long head (BF), tibialis anterior (TA), gastrocnemius medial head (GM), and soleus 6 (SOL) muscles at the following time points: pre (PRE), immediately post (POST), 7 day-1 (D1), day-3 (D3), and day-8 (D8), after a full marathon.

A Article Title: Relationship between isometric contraction intensity and muscle hardness assessed by ultrasound strain elastography. Article Snippet: (0.20 ± 0.05).. SR decreased linearly (P < 0.05) with increasing MVC from rest to 75% MVC, but levelled off from 75 and 100% MVC.. SR was negatively correlated with pennation angle (r = −0.80, P < 0.01) and muscle thickness ( r= −0.78, P< 0.01). |
