Intermuscular force transmission along myofascial chains

Recently Krause and colleagues from Department of Sports Medicine, Goethe University in Germany published a review to provide a systematic overview on tensile transmission along myofascial chains based on anatomical dissection studies and in vivo experiments.

As evidence for the existence of myofascial chains is growing, and the capability of force transmission via myofascial chains has been hypothesized. However, there is still a lack of evidence concerning the functional significance and capability for force transfer.

A systematic literature research was conducted using MEDLINE (Pubmed), ScienceDirect and Google Scholar. Studied myofascial chains encompassed the superficial backline (SBL), the back functional line (BFL) and the front functional line (FFL). Peer-reviewed human dissection studies as well as in vivo experiments reporting intermuscular tension transfer between the constituents of a myofascial chain were included. To assess methodic quality, two independent investigators rated studies by means of validated assessment tools (QUACS and PEDro Scale). The literature research identified 1022 articles. Nine studies (moderate to excellent methodological quality) were included.

And the finding is… Concerning the SBL and the BFL, there is moderate evidence for force transfer at all three transitions (based on six studies), and one of two transitions (three studies). One study yields moderate evidence for a slight, but not significant force transfer at one transition in the FFL.

The findings of the present study indicate that tension can be transferred between some of the examined adjacent structures. Force transfer might have an impact in overuse conditions as well as on sports performance.

However, the authors also acknowledged that different methods of force application and measurement hinder the comparability of results. Considering anatomical variations in the degree of continuity and histological differences of the linking structures is crucial for interpretation. Future studies should focus on the in vivo function of myofascial continuity during isolated active or passive tissue tensioning.


Acute effects of lateral thigh foam rolling on arterial blood flow

A new study on foam rolling now provides new evidence on its effects on the cellular and physiological level.

The study by scientists from Germany assessed the effect of foam rolling on arterial blood flow of the lateral thigh. Twenty-one healthy participants (age 25 ± 2 years, height 177 ± 9 cm, body weight 74 ± 9 kg) were recruited from the medical and sports faculty. Arterial tissue perfusion was determined by spectral Doppler and power Doppler ultrasound, represented as peak flow (Vmax), time average velocity maximum (TAMx), time average velocity mean (TAMn), and resistive index (RI), and with semiquantitative grading that was assessed by four blind-folded investigators. Measurement values were assessed under resting conditions and twice after foam rolling exercises of the lateral thigh (0 min and 30 min post intervention). The trochanteric region, mid portion, and distal tibial insertion of the lateral thigh were representative for data analysis.

The results showed that arterial blood flow of the lateral thigh increased significantly following foam rolling exercises compared to baseline. The study detected a relative increase in peak flow (Vmax) of 73.6% (right after rolling) and 52.7 % (30 min after rolling) , in TAMx of 53.2%and 38.3 % and in TAMn of 84.4% and 68.2 % .

Semiquantitative Power Doppler scores at all portions revealed increased average grading of 1.96 after intervention and 2.04 after 30 min compared to 0.75 at baseline.

This results contribute to the understanding of local physiological reactions to self-myofascial release.
