“…PPTS were assessed to underline mechanical hyperalgesia following EIMD using a mark placed on different points of the nondominant quadriceps using a mechanical pressure algometer (Hilitand, NK-100 Force Gauge, USA) which were standardize between participants and marked to being kept similar between condition (47). Indirect measures of muscle damage were assessed trough MVIC using a Biodex dynamometer (Biodex, Shirley, NY, USA) ( 48) and a 100-mm visual analog scale (VAS) anchored on the left edge of the scale with the phrase "no pain or soreness" and on the right edge "worst pain/soreness imaginable" (49). Participants were asked to rate their painrelated soreness during their for daily living activities (VAS DA ) (45) and after performing a squat at approximate 90 degrees of knee angle (VAS SQ ) (48).…”

This study aims to test the separated and combined effects of mechanoreflex activation and nociception through exercise-induced muscle damage (EIMD) on central and peripheral haemodynamics before and during single passive leg movement (sPLM). Eight healthy young males undertook four experimental sessions, in which a sPLM was performed on the dominant limb while in each specific session the contralateral was: a) in a resting condition (CTRL), b) stretched (ST), c) resting after EIMD called delayed-onset-muscle-soreness (DOMS) condition, or d) stretched after EIMD (DOMS+ST). EIMD was used to induce DOMS in the following 24-48h. Femoral blood flow (FBF) was assessed using doppler ultrasound while central haemodynamics were assessed via finger photoplethysmography. Leg vascular conductance (LVC) was calculated as FBF/MAP. RR-interval were analyzed in the time (RMSSD) and frequency domain (LF/HF). Blood samples were collected before each condition and gene expression analysis showed increased fold changes for P2X4 and IL1β in DOMS and DOMS+ST compared with baseline. Resting FBF and LVC were decreased only in the DOMS+ST condition (-26ml/min and -50ml/mmHg/min respectively) with decreased RMSSD and increased LF/HF ratio. MAP, HR, CO, and SV were increased in ST and DOMS+ST compared with CTRL. Marked decreases of delta peaks and AUC for FBF (∆: -146ml/min and -265ml respectively) and LVC (∆: -8.66ml/mmHg/min and ±1.7ml/mmHg/min respectively) all p<.05. These results suggest that combination of mechanoreflex and nociception resulted in decreased vagal tone and concomitant rise in sympathetic drive that led to increases in resting central hemodynamic with reduce limb blood flow before and during sPLM.

“…In practical terms, analyzing serum biomarkers would be a faster strategy for evaluating muscle recovery after exercise. Understanding the association between myoglobin and C-reactive protein increase after eccentric exercise and muscle force (maximal voluntary contraction) recovery and muscle soreness would be essential as it might provide valuable insights for developing dietary strategies or pharmacological interventions to accelerate muscle recovery [11][12][13][14]. Furthermore, it has the potential to guide physiologists to elaborate adequate training programs for athletes.…”

Eccentric exercise is well-known to induce muscle damage, and biomarkers may be related to the magnitude of impact on muscle force and muscle soreness after exercise. However, this phenomenon still needs to be investigated in more detail. The present study aimed to analyze if a correlation between muscle force, soreness, and biomarkers after eccentric exercise exists in healthy, trained 11 males and females. Eleven volunteers with previous resistance training experience performed 6 x 10 maximal isokinetic eccentric contractions of the elbow flexors in the muscle performance laboratory up to 72 hours after exercise. Peak torque was measured by maximal voluntary isometric contractions (MVIC) and muscle soreness by visual analogic scale (VAS) before, 24h, 48h, and 72h after the isokinetic eccentric exercise protocol. A fluorescence immunoassay analyzer determined Myoglobin and C-reactive protein levels. The MVIC significantly decreased while muscle soreness increased 24h, 48h, and 72h post eccentric exercise. Myoglobin significantly increased 48h and 72h after exercise. Muscle soreness was inversely correlated with MVIC 24h, 48h, and 72h and positively correlated with myoglobin 48h and 72h after eccentric exercise. The myoglobin was not correlated with muscle force. No significant correlation between C-reactive protein and muscle soreness and MVIC was found. In conclusion, our data suggest that myoglobin could be a valuable biomarker to be assessed alongside exercise-induced muscle soreness.

“…Soft tissue injuries and recovery are affected by the nature and location of the trauma and the player’s physical, nutritional, and emotional condition. Many treatment options exist for strains and injuries [ 13 – 18 ]. The most basic treatments are RICES (Rest, Ice, Compression, Elevation, Stabilization), massage, and oral analgesics for pain and inflammation.…”

Background Musculoskeletal injuries are common in collegiate, professional, and military personnel and require expedited recovery to reduce lost worktime. Sustained acoustic medicine (SAM) provides continuous long-duration ultrasound at 3MHz and 132mW/cm2. The treatment is frequently prescribed to treat acute and chronic soft tissue injuries and reduce pain. The objective of this study was to evaluate the efficacy of SAM treatment for musculoskeletal injuries and accelerated recovery. Methods An 18-question electronic survey and panel discussion was conducted on Athletic Trainers (ATs) using SAM treatment in professional, collegiate, and military sports medicine. The survey included both qualitative and quantitative questions. In addition, SAM effectiveness was discussed with expert ATs in a panel discussion. Power calculation of sampling and statistical evaluation of data was utilized for the generalizability of the results. Results Survey respondents (n=97) and panelists (n=142) included ATs from all National Athletic Trainers Association districts. SAM was primarily used for musculoskeletal injuries (83.9%, p<0.001) with a focus on healing tendons and ligaments (87.3%, p<0.001). SAM treatment was also used on joints (44.8%), large muscle groups (43.7%), and bone (41.4%). SAM provided clinical improvement in under 2 weeks (68.9%, p<0.001) and 50% reduction of pain medication (63%, p<0.001). In addition, patients were highly receptive to treatment (87.3%, p<0.001), and ATs had a high level of confidence for improved function and returned to work after 30-days of SAM use (81.2%, p<0.001). Conclusion SAM is an effective, safe, easy to use, noninvasive, comfortable, and versatile therapeutic for healing musculoskeletal injuries.
