The effects of a physical fitness program on the plasma lipids of late adolescent malesMarumoto, Seiko 06 October 1969 (has links)
The effects of an 11-week jogging program on the plasma lipid
fractions and clotting time of 19 late adolescent males (18 to 19
years) were investigated. Total lipids, triglycerides, total and free
cholesterol, phospholipids, non-esterified fatty acids, and clotting
time of plasma were determined. Statistical analysis was applied
to the change in each parameter. Dietary patterns prior to and
following the fitness program were examined.
The mean concentrations of total lipids, total and free cholesterol,
and phospholipids were lower than those reported for young
men; plasma clotting times were longer. The mean plasma triglycerides
and non-esterified fatty acids were comparable to those
observed in adults. Individual values of the plasma lipid fractions
were within the ranges reported in the literature. Consistent relationships
could not be found between dietary intake, changes in
weight, or any of the lipid parameters.
Significant changes in triglycerides, total and free cholesterol,
and non-esterified fatty acids were not apparent as a result of
exercise. There was a significant decrease in phospholipids;
total lipids and clotting time increased significantly following the
fitness program. / Graduation date: 1970

The effect of vitamin B-6 supplementation on fuel utilization and plasma amino acids during exhaustive endurance exercise in menVirk, Ricky S. 16 August 1994 (has links)
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 and amino acid levels during exercise, five trained
males (age: 29±7; V0₂ max: 54.7±6.2 ml/kg/min) performed two separate submaximal,
endurance, exercise tests on a cycle ergometer. Subjects were exercised to exhaustion at
74.5±7.8% V0₂ max in a fasted condition on the seventh morning of two separate nine day
controlled diet periods. The first exercise test (T1) occurred following a control or non-supplemented
(NS) diet (i.e. 1.9 mg B-6/day), and the second exercise test (T2) occurred
following a vitamin B-6 supplemented (S) diet (i.e. 1.9 mg B-6/day + 20 mg PN/day). Blood
was drawn pre, during (i.e. 60 minutes into exercise), post, and post-60 minutes of exercise,
and plasma was analyzed for glucose, lactic acid, glycerol, free fatty acids (FFA), and amino
acids. Expired air was collected for three minutes at 10 minute intervals during both tests.
Although not statistically different, there were observed trends for higher mean lactate levels
and lower mean glycerol and FFA levels in T2 (S) compared to T1 (NS). Mean lactate, glycerol,
and FFA concentrations all changed statistically significantly over time in both exercise tests.
Mean plasma tyrosine levels were significantly lower (p = 0.007) at post-60 minutes of exercise
and mean plasma methionine levels were significantly lower (p = 0.03) at post-exercise in T2
relative to T1. Of the 13 amino acids quantitated, only alanine and histidine concentrations changed significantly over time. Although not statistically significant, mean respiratory
exchange (R) values tended to be higher in T2 compared to T1. Mean oxygen consumption
values were significantly higher (p = 0.02) during the first 10 minutes of exercise and at
multiple later time points showed a trend for being higher in T2 compared to T1. No
statistically significant differences were observed in subjects' performance times to exhaustion
between T1 (1:35:49; hr:min:sec) and T2 (1:31:56). These results indicate that vitamin B-6
supplementation can potentially alter fuel metabolism and plasma amino acid levels during
exhaustive endurance exercise; however, not to such a degree that one's endurance capacity
is affected. / Graduation date: 1995

Carbohydrate loading, vitamin B-6 supplementation, and fuel metabolism during exercise of differing intensity in post-absorptive manDeVos, Ann 21 May 1982 (has links)
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 from a glycogen depletion-repletion
regimen, and to determine the effect of supplemental vitamin B-6
(B6). The diets were: Week 1, 40% CHO normal diet (NC); Week 2,
days 1-3 CHO 11% (LC), days 4-7 CHO 71% (HC); Week 3, same as week
2 but with an 8 mg B6 supplement each day (LC+B6, HC+B6). The men
exercised after an overnight fast on days 4 and 7, upon completing
the depletion or repletion phase. Blood was collected before
exercise (PRE), during the 80% MHR work (DURING), immediately
after completion of the 90% MHR work (POST), and 30 min and 60
min after exercise (30 MIN POST, 60 MIN POST).
Plasma FFA concentrations were from 30% to 75% higher (p<0.05)
after the LC and LC+B6 diets than after the NC-1, NC-2, HC, or
HC+B6 diets, and B6 did not appear to affect plasma FFA levels.
Plasma glucose values were from 3% to 4% lower (p<0.01) for DURING
HC and HC+B6 than DURING NC-1. Since plasma HC and HC+B6 lactate
values were 57% higher (p<0.05) than DURING control values, the
simultaneously low glucose and high lactate levels indicate that
glucose was primarily derived from muscle glycogen in the HC and
HC+B6 conditions. Addition of B6 to the HC diet resulted in
elevated POST lactate levels, but this difference was not significant.
LC glucose and lactate values did not differ significantly
from control values. However, PRE LC+B6 glucose values
were 12% lower than PRE control values (p<0.02) and continued to
be lower during exercise. POST and 30 MIN POST LC+B6 values were
47% lower than the LC values (p<0.005 and p<0.01, respectively).
The glucose and lactate data indicate that B6 supplementation does
alter CHO metabolism when added to a glycogen depletion-repletion
regimen. Due to the possible role of glycogen phosphorylase as
an expanding depot for B6 storage, supplementation with B6 may
cause a more rapid emptying of muscle glycogen stores and a
reduction of athletic endurance. / Graduation date: 1983

Variability in velocity settings of eccentric work and the production of delayed onset muscle soreness : objective and subjective measuresBogle, Phillip G. 03 June 2011 (has links)
The purpose of this study was to compare the effects of two different velocities of eccentric work on delayed onset muscle soreness and associated factors in untrained college-aged males. Eight untrained males 21.6 (+1.7) yrs. were recruited for the study. Three subjects did not crossover design and assigned to either a 60 deg/sec or 150 deg/sec work velocity. One hundred maximal eccentric repetitions were completed separately for both legs. Exercise treatment on both legs was carried out on the Kinetic Communicator Device. Repetitions were divided into twoexercise trials. Following the exercise treatment, 10 sets of 10 repetitions with a 5 second pause between each repetition. A five week rest interval separated the range of motion (ROM) values (24, 48, 72, 122, 144 hrs.), serum creatine kinase (Ck), (pre, 24, 72, 144 hrs.), and and the results of 2 subjective soreness scales were recorded. The results of the study demonstrated no significant difference in the velocity * time interaction for Ck, ROM, and soreness perception values; however, significant findings were demonstrated for the main effect across days within each data collection except for Ck following the 150 deg/sec trial. No significant difference could be found between each leg or between both trials following each exercise treatment. The Ck'response at the faster velocity seemed to indicate that the 150 deg/sec work trial may have produced a greater amount of muscle trauma compared to the 60 deg/sec trial without significantly effecting the soreness response.
