Title   Effect of massage on blood flow and muscle fatigue following isometric 
lumbar exercise
Full source     Medical Science Monitor, 2004, Vol 10, Iss 5, pp CR173-CR178

Backround: This study attempted to investigate the influence of massage on the 
skin and the intramuscular circulatory changes associated with localized muscle 
fatigue. Materials/Methods: Twenty-nine healthy male subjects participated in 
two experimental sessions (massage and rest conditions). Subjects lay prone on 
the table and were instructed to extend their trunks until the inferior portion 
of their rib cage no longer rested on the table. Subjects held this position 
for 90 seconds (Load I). Subjects then either received massage on the lumbar 
region or rested for 5 minutes, then repeated the same load (Load II). Skin 
blood flow (SBF), muscle blood volume (MBV), skin temperature (ST), and 
subjects' subjective feelings of fatigue were evaluated using Visual Analogue 
Scale (VAS). Results: An increase of MBV between pre- and post-load II periods 
was higher after massage than after rest (p<0.05). An increase of SBF at pre- 
and post-load II was observed only under massage condition. An increase of SBF 
between post-load I and pre-load II periods was higher after massage than after 
rest (p<0.05). An increase of ST between post-load I and post-load II periods 
was greater after massage than after rest (p<0.05). The VAS score was lower 
with massage than with rest in the post-treatment period (p<0.01). Conclusions: 
A significant difference was observed between massage and rest condition on VAS 
for muscle fatigue. Lumbar massage administration also appeared to have some 
effect on increasing skin temperature and enhancement of blood flow in local 
regions.
