Effect of short-term sling exercise with whole body vibration recovery method on heart rate, blood pressure and lactic acid level variability

The objective of this study was to compare heart rate, blood pressure, and lactic acid level with different recovery methods after having maximal exercise to provide reliable data regarding efficient recovery methods. Heart rate, blood pressure, and lactic acid level were continuously recorded for 30min at 5-min intervals during a recovery period after performing a maximal exercise test based on the Bruce-protocol. Study subjects were 36 healthy men in the 20s. They were randomly assigned to a passive recovery group (PRG=12 people), a sling exercise group (SRG=12 people), and a sling exercise with whole-body vibration group (SWRG=12 people). One-way ANOVA was conducted to compare the recovery effects by using SPSS 18.0 Korea. The statistical significance was accepted at p<0.05. Our results revealed that SWRG showed significantly faster heart rate recovery than SRG. Systolic and diastolic blood pressure tended to decrease more in the combined group than the PRG. Thirdly, the lactic acid level decreased to a lower level in the combined group than the PRG.
