Single-blinded Randomized Controlled Trial conducted amongst a sample of healthy subjects divided into two different groups: the experimental treatment will consist in bilateral T12-L1 vertebral manipulation, whereas the control group will receive a sham intervention consisting solely in applying tension without properly manipulating. Body temperature, arterial tension and cardiac frequency will be measured before and after the intervention. Changes in the aforementioned variables will be measured.

The current study will correspond to a single-blinded Randomized Controlled Trial with two arms, conducted amongst a sample of healthy subjects, who will be divided into two different groups: the experimental treatment will consist in bilateral T12-L1 vertebral manipulation, whereas the control group will receive a sham intervention consisting solely in applying tension without properly manipulating. Three different variables will be measured prior to and after the intervention: body temperature, arterial tension and cardiac frequency, to subsequently calculate possible changes in the variables, with the aim of establishing the effect of the manipulation and/or sham treatment.
