    Notes: Abstract The effects of 30 min running with stepwise increasing intensity (exhaustive, energy demand approx. 50 → 100% ofVO2max), 60 s supramaximal running (anaerobic, ≥125% ofVO2max) and 40–60 min low-intensity running (acrobic, 40–60% ofVO2max) on serum concentration of muscle-derived proteins were studied in 5 male and 5 female elite orienteerers. S-Carbonic anhydrase III (S-CA III) was used as a marker of protein leakage from type I (slow oxidative) muscle fibres and S-myoglobin (S-Mb) as a non-selective (type I+II) muscular marker. The fractional increase in S-CA III (ΔS-Ca III) was 0.37±0.09 (mean±SEM,p〈0.001), 0.10±0.05 (N. S.) and 0.46±0.09 (p〈0.001) 1 h after exhaustive, anaerobic and aerobic exercise, respectively. The corresponding values for ΔS-Mb were 1.45±0.36 (p〈0.001), 0.39±0.13 (p〈0.01) and 0.67±0.18 (p〈0.001). The value for the ΔS-CA III/ΔS-Mb ratio was 0.68±0.03 after the acrobic exercise, but only 0.25–0.26 (p vs. aerobic exercise 〈0.001) after the two high-intensity forms of exercise. Since type I fibres of skeletal muscle are known to be responsible for power production during low-intensity exercise, whereas fibres of both type I and type II are active at higher intensities, the ΔS-CA III/ΔS-Mb ratio may depend on the recruitment profile of type I vs. type I+II fibres.

    Lipid metabolism during exercise (1980)

    Notes: Summary Seven physically fit (well-trained, maximal oxygen uptake 69.6±4.4 ml×kg−1×min−1) and eight less fit (moderately trained, maximal oxygen uptake 56.1±5.7 ml×kg−1×min−1) healthy male subjects were exercised for 4 h by bicycle ergometry against a pedalling resistance calculated to cause oxygen consumption corresponding to approximately 30% of each individual's maximal oxygen uptake value. Respiratory exchange ratio was estimated at 1 h and blood glucose and lactate concentrations and muscle glycogen content at 2 h intervals. Muscle glycogen content decreased markedly during the first 2 h of exercise in the well-trained group but was similar after 4 h exercise in both groups. No major differences were observed between the two subject groups in blood variable concentrations. Calculations based on respiratory exchange ratio showed that the proportion of carbohydrates utilized in the total energy consumption was 14% in the physically fit group and 25% in the less fit group, thus supporting previous observations that more energy is derived by fat oxidation in well-trained than in less-trained individuals during submaximal work at relatively similar oxygen consumption levels.

    Notes: Abstract Using conversion electron and γ-ray spectroscopy combined with a recoil gating method, excited states in 188Pb have been investigated. Further evidence for two excited low-lying 0+ states has been found leading to an interpretation as a multiple shape coexistence in 188Pb.
