  2. 1. Blood volume expansion following supramaximal exercise : occurrence and contribution to maximal oxygen uptake

    Author : Mirko Mandić; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Previously published research using various types of exercise has shown that central hemodynamic factors such as blood volume (BV) and maximal cardiac output (Qmax) are of large importance in the mediation of improvements in VO2max. Whether this is true for adaptations induced by sprint-interval training (SIT) is unclear. READ MORE

  4. 2. Validity and reliability of a submaximal cycle ergometer test for estimation of maximal oxygen uptake

    Author : Frida Maria Eleonora Björkman; Örjan Ekblom; Tony Bohman; Åsa Tornberg; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Abstract : Maximal oxygen uptake (VO2max) is the highest obtained rate of oxygen consumption during a physically intense dynamic whole-body activity. VO2max is an important factor for many types of physical performance, as well as a strong independent predictor of health and longevity. READ MORE

  5. 3. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

    Author : Amitava Halder; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

    Abstract : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

  6. 4. Cardiac function and long-term volume load : Physiological investigations in endurance athletes and in patients operated on for aortic regurgitation

    Author : Kristofer Hedman; Eva Nylander; Éva Tamás; Lars Brudin; Mats Börjesson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background and aims. The heart is a remarkably adaptable organ, continuously changing its output to match metabolic demands and haemodynamic load. But also in long-term settings, such as in chronic or repeated volume load, there are changes in cardiac dimensions and mass termed cardiac hypertrophy. READ MORE

  7. 5. Assessment of Aerobic Capacity A Novel Rating Scale and Further Development of an Exercise Test including Analysis of Gas Exchange

    Author : Anita Wisén; Människan i rörelse: hälsa och rehabilitering; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Physical medicine; Time constant of V O2; Cycle ergometer; Perceived Capacity; Perceived exertion; Heart rate; Oxygen uptake; Reference values; Oxygen kinetics; Repeatability; Thresholds;

    Abstract : Different methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. READ MORE
