Methods
A randomized complete-block design experiment was
realized under standardized procedures and airconditioned
temperatures at 24 C in the Ergonomics Laboratory,
Faculty of Science, Rangsit University. The RSU
ethical committee approved the research protocol.
The participants underwent three types of Thai traditional
massage: the Sen Sib (SS), Ratchsamnak (RS) and
Chaloeysak (CS) methods (Tyroler, 2013) successively. Each
treatment took about 15e30 min. An interval of 2 weeks
between the sessions allows an assumption that the influence
on alternating the methods would not interfere the
results.
