简要总结
This study investigates the influence of a remote, painful stimulus on stretch tolerance. Half of the participants will receive a conditioning painful stimulus following static stretching while the other half will rest quietly.
详细描述
The effect of stretching on joint range of motion is primarily related to changes in the tolerance to stretch, but the mechanisms underlying this change are still largely unknown.
The nervous system has an inbuilt ability to modulate the perceived magnitude of afferent noxious stimuli via supraspinally mediated endogenous pain inhibition or facilitation and by engaging endogenous mechanisms pain tolerance in healthy individuals is known to increase. Thus increasing the tolerance to pain could potentially increase range of motion following stretching.

研究组 & 干预措施
Experimental pain group
subjects in the pain group were instructed to immerse their non-dominant hand into a container with circulating water at 1˚C to 4˚C and keep it there for 2 minutes. They were instructed to immerse it to wrist-level and keep the hand open.
干预措施: Cold pressor test (Other)
Control group
Participants rested in a seated position for 5 minutes.
