Four young trained men were studied during 50 min of continuous
bicycle ergometer exercise [30 min at 60%, 15 min at 80%,
and 5 min at 90% maximal heart rate (MHR)] to elucidate changes
in fuel metabolism resulting fr ...
The purpose of this study was to determine the relationship between the overall
changes in concentration of plasma pyridoxal 5'-phosphate (PLP), red blood cell PLP (rbc
PLP) and plasma glucose during an oral glucose to ...
The purposes of the research presented in this thesis were
to: (l) assess the nutritional status of vegetarian and nonvegetarian
Seventh-day Adventists (SDA), non-SDA non-vegetarians,
and non-vegetarian hormone depend ...
There were two main purposes to this study. The first was to determine the
vitamin B-6 and pyridoxine β-glucoside content of selected foods commonly
consumed in Malawi. The second was to examine the effect of preparati ...
The purpose of this study was to examine the effect of extreme exercise on vitamin B-6
metabolism and urea nitrogen. Nine men and five women completed two 5-day trials; Trial 1
(T1) included a 50-km ultramarathon on da ...
This investigation was designed to add to present understanding
of vitamin B-6 (B6) metabolism during exercise. Ten women, 5
aerobically trained and 5 untrained, were fed 4 controlled diets: a
moderate carbohydrate (4 ...
Previous studies have found that smoking may have a negative effect on
vitamin B-6 indices and have demonstrated a possible association between smoking
and depressed plasma pyridoxal-5'-phosphate (PLP) concentration. I ...
Trained male cyclists (6 in study 1, 5 in study 2) cycled to exhaustion (EXH) at
75% of VO₂ max twice; once in the non-supplemented (NS) state and once in the vitamin
B-6 (B-6)(20 mg PN) supplemented (S) state. The die ...
The study was designed to indirectly understand muscle
glycogen utilization during prolonged exercise when either
glucose, fructose, or water is ingested. Eight trained
adult males exercised on a cycle ergometer at 58 ...
The effect of dietary glycosylated vitamin B-6 on the bioavailability
of vitamin B-6 was determined in 4 women. A 44-d metabolic-balance diet
study was divided into a preliminary 8-d adjustment period followed by
two ...
Recently, high carbohydrate diets were recommended for the
treatment of diabetes mellitus. All aspects of these diets, however,
have not been fully tested — particularly in insulin dependent
diabetes mellitus (IDDM). ...
This study was designed to evaluate the effect of glucose on plasma pyridoxal 5'-
phosphate (PLP) concentration. The objective was to determine whether there was a
negative relationship between glucose ingestion and pl ...
Two studies were conducted to determine the effect of varying vitamin B-6 (B-
6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP)
concentration in peripheral blood mononuclear cells (PBMC) in yo ...
The purpose of this study was, first, to investigate whether there
is a vitamin B-6 requirement for carnitine synthesis and, second, to investigate
the effect of fasting on vitamin B-6 metabolism. An experimental
grou ...
Four studies were conducted to evaluate the effect of varying levels of vitamin
B-6 (B6), protein and pyridoxine glucoside (PNG) on B6 status and requirements of
women. In the first two studies, women were fed a consta ...
The effect of vitamin B-6 (B-6) status on plasma fatty acids (FA) levels and lipid
metabolism was investigated in this metabolic study. Eight female subjects were fed for 28
days. For the first 7 days, they were fed a ...
The objectives of this study were a) to determine
if pyridoxine (PN) supplementation increases the rate at
which plasma urea and ammonia return to basal levels,
following exercise, b) to determine, by open circuit
ca ...
Previous studies suggest that vitamin B-6 supplementation can alter fuel metabolism during
exercise and plasma amino acid levels at rest. To examine the effect of vitamin B-6
supplementation on plasma fuel substrates a ...
