Effect of Warm-Up Exercise upon Muscular Performance Using Hypnosis to Control the Psychological Variable

Observations were made on 15 male subjects riding a bicycle ergometer 100 revolutions against time after two conditions, warm-up by means of over-all bodily activity for a period of ten minutes and no warm-up. The subjects were tested four times, two times following each condition. The subjects were in a deep hypnotic state prior to all testing, and when tested they had no conscious awareness of whether they had warmed up. Performances after the two conditions were about the same with the rate of pedaling slightly slower following warm-up. The differences in mean performances were not statistically significant. There was no evidence of muscle strain or injury resulting from performance without warm-up.
