We investigated thoracic temperatures (Tth) during different activities of the endothermic fruit beetle Pachnoda sinuata and analysed which energy substrates are used for the pre-flight warm-up of its flight muscles. Pachnoda sinuata elevates its Tth prior to take-off either by basking in the sun or by warming endothermically to a narrow range around 34 degreesC. During lift-generating tethered...

In a recent report (1), we have shown that the characteristic rise in the total metabolism, pulmonary ventilation and pulse pressure, caused by the injection of a small amount of epinephrin,' is not significantly different in obese and normal individuals. The respiratory quotient, on the other hand rises definitely less in the obese persons than in the normal subjects. This difference suggests ...

Apples (Malus domestica, Borkh.) which are not stored at low temperature or in a properly controlled atmosphere (CA) may have a high metabolic rate during the postharvest stage resulting in losses in quality. The aim of this study was to evaluate the quality of ‘Royal Gala’ apple fruit stored in accordance with a new method of dynamic controlled atmosphere (DCA).The respiratory quotient (RQ) wa...

The many observations on blood sugar in exercise have revealed widely different conditions. Thus one may have extreme hypoglycemia as found by Levine, Burgess and Derick (1) in some marathon runners, or at the other extreme, hyperglycemia as in football players (2). A moderate decrease in the concentration of sugar in the blood (B. S.) has been found by Christiansen (3) in exercise of one hour’...

[Purpose] The purpose of this study was to present aerobic exercise that can be performed together with respiratory muscle strength training and examine whether the vital capacity of individuals can be enhanced when respiratory muscle strength training is conducted together with aerobic exercise. [Subjects and Methods] The subjects were 10 male students and 8 female students. The sling exercise...
