Influence of exercise using the Valsalva maneuver on vital signs in young adults

[Purpose] To examine the influence of exercise using the Valsalva maneuver on vital signs. [Participants and Methods] Twenty-five healthy university students participated in the study. All participants were instructed to perform the squat under two loading intensities, that is, with barbell weights of 40% and 80% of body weight, under two conditions: no breath-holding (Control group) and breath-holding (Valsalva group). Blood pressure, pulse pressure, lactic acid level, and Borg scale scores were measured before and after each exercise session. [Results] Systolic blood pressure, mean blood pressure, and pulse pressure increased in the 80% Control, 40% Valsalva, and 80% Valsalva groups. [Conclusion] The use of the Valsalva maneuver could influence the vital signs of young, healthy participants.
