   Sammanfattning : Background: A squat is a common exercise that is used in many areas of strength training and for different purposes and the literature is inconclusive when it comes to whether the weight lifting belt (WB) affects performance and/or is injury-preventing. The use of breathing techniques is common during heavy lifting and therefore the practice of the breathing teqnice; valsalva maneuver (VM) may be of interest to study and if this along with the WB can provide some advantages in power output and velocity.

3. 2. Hemodynamic Model of the Cardiovascular System during Valsalva Maneuver and Orthostatic Changes

   Uppsats för yrkesexamina på avancerad nivå, Radiofysik

   Författare :Niklas Moberg; [2011]
   Nyckelord :Hemodynamics; model; Valsalva; cardiovascular;

   Sammanfattning : The goal of the Master's Thesis was to extend an existing cardiovascular model to include the mechanics of the lung, thus allowing to simulate breathing maneuvers such as the Valsalva maneuver and the Forced Vital Capacity maneuver. This included a remodeling of the pulmonary capillaries and of the existing interactions of the model with the intrathoracic pressure. LÄS MER
