BACKGROUND: The purpose of this study was to examine the effect of a punching a punching bag on blood pressure in young adults with elevated blood pressure.
METHODS: The study population consisted of 19 young adults (age: 25.2±4.8 years old; body mass index: 24.1±3.3 kg/m2) with elevated blood pressure (≥120 mm Hg). Anthropometric and body composition (DXA) measurements were determined before the punching session. Participants then performed one session of 15 minutes of punching on a punching bag while emotionally express themselves (i.e. shouting, venting). Blood pressure was measured at baseline and during a 2 hour period after the punching session. Heart rate as well as physical activity energy expenditure and intensity were measured using a sensewear armband during the punching session.
RESULTS: We noted that systolic blood pressure was significantly reduced 30 min after the punching session and was maintained until min 120. The highest change in percentage for systolic pressure (10.6 %) was observed after 90 min. In addition, diastolic blood pressure was significantly decreased 15 min after the punching session and was maintained until min 90. The highest change in percentage for diastolic pressure (8.4 %) was observed after 90 min.
CONCLUSIONS: A 15 min punching session resulted in a significant decrease in both systolic and diastolic blood pressure in young adults with elevated blood pressure.
