The effect of boron supplementation on plasma testosterone, lean body mass and strength was investigated in male weightlifters. A double blind pretest - posttest, true experimental design was utilized. Ten male bodybuilders (ages 20-26 yr) were given a 2.5 mg boron supplement, while 9 male bodybuilders (ages 21-27 yr) were given a placebo each day for seven weeks. Plasma total and free testosterone values were determined by radioimmunoassay, lean body mass was determined by hydrostatic weighing, and strength measurements were determined by 1 repetition maximum (1RM) in the squat and bench press on days 1 and 49 of the study. Plasma boron was analyzed by microwave digestion and inductively - coupled argon plasma spectrometry (ICAP). / There was a significant difference in plasma boron due to group membership. The mean plasma boron level of the experimental group increased from (mean $\pm$ SD) 20.1 $\pm$ 7.7 ppb pretest to 32.6 $\pm$ 27.6 ppb posttest, while the control group mean decreased from 15.1 $\pm$ 14.4 ppb pretest to 6.3 $\pm$ 5.5 ppb posttest. Large variations were noted within both groups. An analysis of variance indicated no significant effect of boron supplementation on any of the dependent variables. Both the boron-supplemented group and the control group demonstrated significant increases in total testosterone (p $<$.01), lean body mass (p $<$.01), 1RM squat (p $<$.0001) and 1RM bench press (p $<$.01). A 2 x 2 correlation matrix between percent change of each plasma testosterone value and percent change of each strength value revealed no significant relationships. The findings suggest that seven weeks of bodybuilding can increase total testosterone, lean body mass and strength in lesser-trained bodybuilders. / Source: Dissertation Abstracts International, Volume: 52-10, Section: B, page: 5198. / Major Professor: Nancy R.

Reports that inadequate dietary calcium intake may contribute to age-related bone loss as well as hypertension have prompted the use of calcium supplements for both prevention and therapeutic purposes. However, the role of calcium in age-related bone loss is controversial. Several studies have shown an antagonistic interaction between calcium and iron in humans and between calcium and both iron and magnesium in animals. / The present double-blind, placebo-controlled, randomized study examined the effects of calcium supplementation for 12 weeks on iron and magnesium status of a group of adult, premenopausal women. Measures of iron status included hematocrit, hemoglobin, serum iron, serum ferritin, and total iron binding capacity; serum calcium and serum magnesium were used to determine calcium and magnesium status. / Thirty-five women, average age 30, were randomly assigned to the calcium supplement or placebo group. The calcium group was given 1000 mg of calcium carbonate to be taken with each of two meals (500 mg at each meal); the control group received a placebo also to be taken with each of two meals. Urinary 24-hour calcium was measured as a test of subjects' compliance. / Average intakes of RDA nutrients showed no significant differences between groups except for thiamin and vitamin C; intakes of these nutrients were greater in the calcium group. Only two covariance responses, ferritin and urinary calcium, showed a significant difference between the two groups' laboratory measures after adjustment for pre-values. A significant drop in ferritin occurred after 12 weeks of calcium supplementation in the calcium group compared to the placebo group (29.83 vs 40.53 ng/ml, p $<$ 0.0001). Post 24-hour urinary calcium values were greater in the calcium group (12.63 vs 9.58 mg/dL, p $<$ 0.0001). / These results suggest that regular use of calcium carbonate supplements with meals makes it difficult for women to maintain iron stores. Iron status may need to be monitored closely in people taking calcium supplements. / Source: Dissertation Abstracts International, Volume: 53-03, Section: B, page: 1296. / Major Professor: Nancy Green. / Thesis (Ph.D.)--The Florida State University, 1992.

The effect of simultaneous ingestion of L-amino acids and whole protein on plasma amino acid concentrations was investigated in 10 males, ages 18.5 to 33.9 years. Subjects ingested in trial one, low fat cottage cheese, in trial two an L-amino acid mixture simulating the composition of cottage cheese and in trial three a combination of cottage cheese and the L-amino acid mixture. Each trial provided one-third of the subjects' daily protein requirement and equivalent amounts of amino acids. Blood samples for plasma amino acid analyses were obtained from subjects before each trial and at 30, 60, 90, 120, 150, 180 and 240 minutes postprandially. Mean changes in total plasma amino acid concentrations between trials one and two and trials one and three at 30 minutes (p $\leq$ 0.05) and between trials one and three at 150 minutes (p $\leq$ 0.10) differed significantly. Mean changes in essential plasma amino acid concentrations between trials one and two and trials one and three at 30 minutes (p $\leq$ 0.05) and between trials one and three at 60 and at 150 minutes (p $\leq$ 0.10) differed significantly. The results of this study show that under physiological conditions mean increments in total, essential and individual plasma amino acid concentrations were higher, peaked faster, but decreased more quickly after ingestion of L-amino acids alone or with whole protein than after ingestion of whole protein alone. Ingestion of either L-amino acids, whole protein or the mixture of L-amino acids and whole protein was equally effective in increasing total plasma amino acids concentrations over the four hour time period. Further studies assessing the effects of different sources of nitrogen on nitrogen balance and on protein synthesis are required in individuals with normal gastrointestinal function to establish when L-amino acid mixtures should be administered in relation to whole protein ingestion. / Source: Dissertation Abstracts International, Volume: 48-12, Section: B, page: 3533. / Thesis (Ph.D.)--The Florida State University, 1987.
