“…The results of this study show that wearing an unstable shoe led to increased MG activity, which can lead us to think that venous return variations were more associated to MG EMG activation. Instantaneous changes in surface EMG amplitude may provide a good estimate of intramuscular pressure changes during the rising part of isometric, but also of concentric, voluntary contractions (Maton, Thiney et al, 2006). During contraction, the gastrocnemius and soleus muscles drive blood into large capacity PV and CFV.…”

Purpose: To quantify the effect of unstable shoe wearing on muscle activity and haemodynamic response during standing.Methods: Thirty volunteers were divided into 2 groups: the experimental group wore an unstable shoe for 8 weeks, while the control group used a conventional shoe for the same period. Muscle activity of the medial gastrocnemius, tibialis anterior, rectus femoris and biceps femoris and venous circulation were assessed in quiet standing with the unstable shoe and barefoot.Results: In the first measurement there was an increase in medial gastrocnemius activity in all volunteers while wearing the unstable shoe. On the other hand, after wearing the unstable shoe for eight weeks these differences were not verified. Venous return increased in subjects wearing the unstable shoe before and after training. Conclusions:The unstable shoe produced changes in electromyographic characteristics which were advantageous for venous circulation even after training accommodation by the neuromuscular system.

“…Previous studies have also shown that compression elevates the intramuscular pressure, alternately adding to the increase in pressure produced by the muscle contraction itself [13,14]. However, during movement, the actual pressure applied on the body exhibits periodic fluctuations.…”

Abstract. BACKGROUND:Previous studies have not used neurophysiological methodology to explore the damping effects on induced soft-tissue vibrations and muscle responses. OBJECTIVE: This study aimed to investigate the changes in activation of the musculoskeletal system in response to soft-tissue vibrations with different applied compression conditions in a drop-jump landing task. METHODS: Twelve trained male participants were instructed to perform drop-jump landings in compression shorts (CS) and regular shorts without compression (control condition, CC). Soft-tissue vibrations and EMG amplitudes of the leg within 50 ms before and after touchdown were collected synchronously. RESULTS: Peak acceleration of the thigh muscles was significantly lower in CS than in CC during landings from 45 or 60 cm and 30 cm heights (p < 0.05), respectively. However, the damping coefficient was higher in CS than in CC at the thigh muscles during landings from 60 cm height (p < 0.05). Significant decrease in EMG amplitude of the rectus femoris and biceps femoris muscles was also observed in CS (p < 0.05). CONCLUSION: Externally induced soft-tissue vibration damping was associated with a decrease in muscular activity of the rectus femoris and biceps femoris muscles during drop-jump landings from different heights.

“…The amplitude and frequency domains of electromyographic (EMG) signal patterns reflect electrical activity changes, motor unit recruitment, and conduction velocity of the active muscle fiber membrane during movement [10]. A majority of current EMG studies on compressive apparel focused on the relationship between varying intramuscular pressure and muscle reactions [11,12]. Previous results indicated that compression definitely increases intramuscular pressure [12].…”

However, the mechanism by which increased intramuscular pressure affects EMG time and frequency domain behavior during long-duration muscle actions has yet to be elucidated.…”

Abstract. BACKGROUND:The potential mechanism of compression apparel remains unclear to date because of insufficient knowledge on the influence of compressive level on muscular responses. OBJECTIVE: To explore the influence of external leg compression on (a) the muscle force and endurance of the quadriceps femoris and (b) the muscle activation patterns during prolonged muscle actions. METHODS: Twelve male participants performed consecutive maximal concentric muscle actions of the quadriceps in compression garment (CG) and control condition (CON) at two angular velocities on the Contrex. The EMG amplitude and frequency of the rectus femoris (RF), vastus lateralis (VL), and vastus medialis were quantified during the concentric phase of the knee extension movement. RESULTS: There was no significant compression effect on muscle force and total work during knee extensions. Contrarily, the overall EMG amplitude was significantly lower in CG than in CON at 60 and 300• /s. Additionally, the EMG frequency of the RF and VL was significantly higher in CG than in CON at 60• /s. CONCLUSION: Increased external pressure is associated with changes in EMG time and frequency domain behavior. These effects can potentially relieve muscle fatigue and improve muscle endurance during long-term exercise.
