1. 1. Physical loads and aspects of physical performance in middle-aged men and women

   Författare :Margareta Torgén; Uppsala universitet; []
   Nyckelord :Medical sciences; physical work load; age; gender; muscle strength; aerobic power; sensory threshold; epidemiology; questionnaire; reproducibility; validity; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : This investigation aimed at a description of different aspects of physical loads during a 24 year follow-up (1970-1993) in 484 men and women born between 1935 and 1952, in relation to different aspects of physical performance, as measured at follow-up. The subjects were originally recruited in 1969 from the Stockholm county generalpopulation. LÄS MER

3. 2. The Effects of Aerobic Exercise on Human Skeletal Muscle Adaptations to Resistance Exercise

   Författare :Tommy Lundberg; Per Tesch; Hans Hoppeler; Mittuniversitetet; []
   Nyckelord :concurrent training; endurance; gene expression; hypertrophy; muscle strength and power; protein phosphorylation;

   Sammanfattning : Aerobic exercise (AE) may interfere with muscle adaptations induced by resistance exercise (RE). Three experimental campaigns were conducted to explore the influence of AE on molecular, functional and muscular adaptations to acute and chronic RE. Twenty-nine men performed unilateral knee extensor RE preceded by AE (AE+RE). LÄS MER

4. 3. Mitochondrial function in human skeletal muscle: with special reference to exercise and training

   Författare :Michail Tonkonogi; Högskolan Dalarna; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :aerobic metabolism; oxidative phosphorylation; mitochondria; oxygen utilisation; citrate synthase; ADP sensitivity; ATP; muscle fibres; hydrogen ions; lactate; free radicals; proton leak; uncoupling; exercise; aerobic metabolism; oxidative phosphorylation; mitochondria; oxygen utilisation; citrate synthase; ADP sensitivity; ATP; muscle fibres; hydrogen ions; lactate; free radicals; proton leak; uncoupling; exercise;

   Sammanfattning : The overall objective of this thesis was to study the adaptation of oxidative function in human skeletal muscle to acute exercise of different modes, intensities and durations, and to endurance training. The effects of endurance training on mitochondrial function were evaluated in cross-sectional and longitudinal studies by measurements of mitochondrial oxygen consumption in isolated mitochondria and permeabilised muscle fibres and measurements of mitochondrial ATP production rate in isolated mitochondria.

5. 4. The application of the Critical Power construct to endurance exercise

   Författare :Kerry McGawley; Helen Carter; Jeanne Dekerle; Gary Brickley; Jo Doust; Harry Rossiter; University of Brighton; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Critical power (CP) is a theoretical construct reflecting the highest work rate that can be maintained by continuous aerobic energy resynthesis for an infinite period of time.  In practice, however, the CP estimate derived from mathematical modelling usually leads to exhaustion within 1 h.

7. 5. Firefighters' physical work capacity

   Författare :Ann-Sofie Lindberg; Christer Malm; Juha Oksa; Desiree Gavhed; Peter Krustrup; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical demands; performance; work capacity; aerobic fitness; anaerobic fitness; muscle strength; muscle endurance; balance; ergonomics; physical testing; SIMCA;

   Sammanfattning : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. LÄS MER
