The day 21 response of the Long-Evans pregnant rat to marginal dietary zinc intake was investigated in this experiment. Day 20 and 21 food intakes of zinc-restricted dams were below the control group amounts and indicated that dietary nitrogen and energy did not meet gestation requirements. Intravenous injections of tracer doses of [14C]alanine provided(More)
Some effects of various degrees of zinc deprivation during pregnancy have been examined in dams and offspring. After mating, the dams were fed a biotin enriched, 20% sprayed egg white diet which contained less than 1 ppm zinc. Zinc was provided in the drinking water at one of the following concentrations: 1, 2, 3, 5, 11, or 25 mg/liter. Pups were taken by(More)
Schirmer tear tests I and II values for 10 healthy cats were 16.2 +/- 3.8 mm/min and 13.2 +/- 3.4 mm/min, respectively. Surgical removal of the lacrimal gland or the third eyelid gland from the left eye resulted in decreased Schirmer tear test-I values. Clinical signs of keratoconjunctivitis sicca were not seen until the lacrimal and third eyelid glands(More)
UNLABELLED Rates of physical activity remain low despite public health efforts. One form of physical activity that provides significant physiological benefit but has not been evaluated in terms of affective and enjoyment responses is interval exercise. PURPOSE The purpose of this study was to compare affect and enjoyment assessed before, during, and after(More)
This study was conducted to characterize nitrogen retention in response to marginal dietary zinc during gestation. Long-Evans rats were randomly assigned to one of two dietary groups on day 1 of gestation. The dams were fed a basal diet supplemented with either restricted or control levels of zinc. Feces and urine were collected for 24 h on day 20 of(More)
The purpose of this study was to assess the effect of sprint interval training on rating of perceived exertion. 20 healthy participants (11 men, 9 women; M age = 23 yr.) completed a maximal cycle ergometer test and two high-intensity interval training cycling sessions. Each session utilized the same work-to-rest ratio (1:1), work intensity (90% max),(More)
The taste behavior of rats subjected to dietary depletions of copper and/or vitamin B-6 was tested. Weanling rats were fed casein-based methionine supplemented diets according to a 2 X 2 factorial design: -Cu/-vitamin B-6; -Cu/+vitamin B-6; +Cu/-vitamin B-6; +Cu/+vitamin B-6. Short-term (18 min) taste tests were conducted daily to assess the effects of the(More)
Low-volume, high-intensity interval training has been garnering attention in the exercise physiology literature recently due to its proposed time-efficiency. Also, recent work comparing continuous exercise to high-intensity interval training demonstrated superior ratings of perceived enjoyment following interval training. However, the dual-mode model(More)
Ratings of perceived exertion (RPE) were developed to assess exertion during exercise testing. However, assessments of RPE prior to and after exercise have become common and potentially important in understanding exercise behaviour. The purpose of this project was to compare RPE taken before, during and after interval and continuous exercise sessions.(More)
