    Population studies of leukocyte-reactive antinuclear antibody and HLA antigens (1981)
    Springer
    Rheumatology international 1 (1981), S. 103-105

    Notes: Summary The prevalence of serum leukocyte-reactive antinuclear antibody (LR-ANA) was determined in 31 patients with ankylosing spondylitis (AS), their age-and gender-matched normal controls, and two tribes of 340 West Coast Canadian Indians (Bella Coolas and Haidas). At a serum dilution of 1:10, the prevalence of LR-ANA in AS and controls was 45% and 7%, respectively. At 1:20 dilution, the prevalence was 23% in AS, 0% in controls, 29% in Bella Coolas and 27% in Haidas. No concordance was found among LR-ANA, HLA-B27 and CREG-B7, and nine HLA-A and seven HLA-B antigens in the Indian tribes. These studies confirm an increased prevalence of LR-ANA in AS and AS kindreds. but the latter association appears to be independent of HLA antigens.

    Specificity of the anaerobic threshold in endurance trained cyclists and runners (1981)
    Springer
    European journal of applied physiology 47 (1981), S. 93-104

    Notes: Summary This study examined the specificity of maximum aerobic power and the anaerobic threshold (AT) in 10 endurance-trained cyclists and 10 endurance-trained runners who performed continuous progressive work tests on the bicycle ergometer and treadmill. Dependent ‘t’ tests for $$\dot V$$ O2 max l/min−1 indicated that the cyclists scored higher on the bicycle ergometer ( $$\bar X$$ =4.5 l/min−1) than the treadmill ( $$\bar X$$ =4.34 l/min−1) but the difference was not statistically significant. By contrast, the runners fared significantly better (p〈0.05) on the treadmill ( $$\bar X$$ =68.1 ml/kg·min−1) compared with the bicycle ergometer ( $$\bar X$$ =61.7 ml/kg·min−1). When the AT was expressed as a percentage of $$\dot V$$ O2 max, there were no significant differences between the cyclists (66.3%) and runners (61.2%) on the bicycle ergometer or the runners (77.3%) and cyclists (74.3%) on the treadmill. However, this tendency for the better score to be registered by the group tested on the activity for which it trained was most pronounced when the AT was expressed in l/min−1 and ml/kg·min−1·Independent ‘t’ tests accordingly indicated that the cyclists (3.0 l/min−1) had significantly (p〈0.05) greater AT's than the runners (2.56 l/min−1) on the bicycle ergometer whereas the runners (52.7 ml/kg·min−1) had significantly (p〈0.05) higher AT's than the cyclists (46.8 ml/kg·min−1) on the treadmill. These data suggest that the adaptive responses to exercise are in part a function of the specific movement patterns executed in training. Thus, if $$\dot V$$ O2 max and the AT are to be measured in the laboratory, the tests must allow optimal innervation of the specifically trained muscle fibres.
