    Notes: Résumé On a observé que les hémolysines d'Ochromonas malhamensis ont été tendues inactives par differentes protéines. Ce sont les enzymes du foiedu rat qui ont apparemment détruit les hémolysines. Cette observation peut expliquer l'absence de mortalité chez les souris et les rats pendant l'injection d'hémolysines.

    Notes: Summary The effect of a backpack load (20 kg) on oxygen consumption while walking and running at different speeds was investigated. Fifteen males walked and ran (with and without load) up a 5% sloped treadmill at 6.4, 7.2, 8.0, 9.6, and 11.2 km/h (4, 4.5, 5, 6, and 7 mph). While walking $$\dot V$$ O2 rose at a rate of 0.6 (l/min)/(km/h) and while running 0.3 (l/min)/(km/h). The mean oxygen consumption at the various speeds was 28.65, 33.78, 40.64, 46.84, 54.48 ml O2/kg BW/min, respectively, for the whole group without load and 26.52, 32.26, 38.28, 44.26, 48.16, respectively, with load. The breaking point between walking and running was at about 8.2 km/h. Carrying the load increased $$\dot V$$ O2 at a constant rate, and induced a breaking point between walking and running at a significantly lower speed for the smaller subjects than for the more robust ones. The results indicate that for certain tasks involving endurance and heavy load carriage, people should be selected according to criteria which integrate aerobic capacity and anthropometrical features.

    Effect of an iron supplement on body iron status and aerobic capacity of young training women (1991)

    Notes: Summary Serum iron deficiency has a high incidence in female athletes. We investigated the effects of a daily oral iron supplement, (160 mg) administered during an intensive 7-week physical training programme, on body iron status, and the maximal aerobic capacity (VO2max) of 13 women (group A) compared to 15 who took a placebo (group B). The subjects were 19 years old. Blood samples were obtained before training began and on days 1, 7, 21 and 42 of training. They were analysed for packed cell volume (PVC) and for haemoglobin (Hb), 2,3-diphosphoglycerate (2,3-DPG), haptoglobin, iron and ferritin concentrations. TheVO2max was measured on days 0, 21 and 42 of training. Following 21 days of training Hb, PCV and ferritin were significantly higher (P⩽0.01) in group A compared to group B. Over the training period Hb rose by 9.3% and 2.4% in groups A and B, respectively. At the end of training 66% of group B exhibited ferritin concentrations below 10 ng·ml−1, while none of group A had such low values. MeanVO2max of group A had increased by 7.5% following 21 days of training (P⩽0.01) and by 15.3% after 42 days. No appreciable increase inVO2max had occurred in group B by day 21 (significantly lower thanVO2max of group A;P⩽0.05), however by day 42 it had increased by 14.3% (P⩽0.05). In both groups 2,3-DPG·g Hb−1 had increased significantly (P⩽0.005) by day 7 (22%) and remained at that level for an additional 35 days. We concluded that a daily oral iron supplement given to young women during intensive training improved several haematological variables and their body iron status. This improvement was associated with an increasedVO2max only during the early stages of their training (day 21) compared with the placebo group.

    The effect of environmental temperature on testosterone and cortisol responses to high Intensity, intermittent exercise in humans (1996)

    Notes: Abstract The purpose of this study was to examine the testosterone, cortisol, and the molar ratio of testosterone to cortisol (T:C) blood concentration responses to intermittent, high intensity exercise in the heat. Eight active men [mean age 25 (SD 3) years, mass 71.1 (SD 5.5) kg, height 175.9 (SD 4.4) cm] performed two series of five 15-s Wingate anaerobic power tests in both hot (H, 35°C) and thermoneutral (TN, 22°C) environments. Each period of exercise was separated by 30-s of active recovery. Each series was separated by 60 min of passive recovery. Blood samples were obtained before (PRE), immediately post (IP), and 5(5R), 10(10R), 15(15R), 30(30R), 45(45R), and 60(60R) min following exercise. Peak power was significantly higher, during the first series of exercise, in the H compared to TN. No significant differences were seen in any of the variables between the first and second series of exercise in either environmental condition. Furthermore, no significant differences between these conditions were observed in heart rate, blood lactic acid concentration, or rectal temperature. A significant decrease in cortisol concentration was observed between PRE and IP, during both conditions. However, no significant interactions between TN or H were seen. No change from PRE was observed in testosterone or T:C during either TN or H. It would appear that testosterone and cortisol respond similarly to repeated periods of short duration high intensity exercise, in either thermoneutral or moderately hot environments.

    Notes: Summary Victims of heat stroke exhibit several clinical features which are also encountered in endotoxaemia. In order to investigate these similarities hyperthermic rats were used to explore the possibility that high body temperature results in increased permeability of intestinal wall to endotoxin. 125I endotoxin was introduced into intestinal segments taken from non-heat exposed rats. The segments were then incubated at 37

    Notes: Summary Previous studies have shown that true maximal oxygen uptake (VO2max) obtained by means of cycle ergometer and step test are lower than the VO2max measured during uphill treadmill running. The predicted VO2max measured by ergometer was even lower. Four different methods for the determination of VO2max within the same group of examinees were compared: True VO2max by treadmill, ergometer, step test, and predicted VO2max (Astrand-Rhyming). This study was performed on 15 healthy non-professional sportsmen. They underwent progressive test protocols on alternating days and the results were as follows — VO2max expressed in ml O2 kg BW/min (mean±SD): treadmill running 63.8±4.7; ergometer cycling 60.2±5.6; step test 59.6±5.2 and predicted VO2max 59.9±6.9. The VO2max as determined by uphill treadmill running was significantly higher than with the other methods. No significant difference was found between true VO2max determined by the ergometer and step test. However, step test and properly executed Astrand-Rhyming test again proved to be reliable and deviate from the treadmill test by only 6%. Maximal heart rate was sgnificantly higher in the treadmill and step tests than in the direct ergometer test.
