“…In our opinion, the effects of vitamin B 6 to increased body weight correlated with increased feed intake may be associated with an increased appetite in rats or a diet enriched in vitamin B 6 is tastier for rats. Several authors revealed changes in B 6 concentration and metabolism induced physical exercise [21,22]. However, they also indicated that this change does not increase the vitamin B 6 requirement of growing rats [23].…”

“…According to Hadj-Saad et al [46], vitamin B 6 levels in the blood increase after 1 hour of an intensive swimming exercise in rats as due to its being shifted from a muscle deposit pool, however, levels decrease after 9-weeks of training [47]. Vitamin B 6 is responsible for protein and amino acid metabolism and a cofactor for many enzymes participating in amino acid transformation.…”

Purpose. Homocysteine is a non-protein amino acid and elevated blood levels are often caused by inappropriate lifestyles, leading to atherosclerosis and cardiovascular diseases. the aim of this study was to determine the levels of homocysteine after a 9-month training program. Methods. the group studied consisted of obese and overweight women, as well as women with normal body mass. During the training program, control examinations were carried out four times and the following parameters were analyzed: homocysteine blood levels, body mass, BMI, a single 10-minute exercise at a workload of 100W and the VO 2 max measured using the Astrand-ryhming method. Results. the highest homocysteine levels were found in obese women and the lowest in lean women. Higher levels were observed in older women (aged over 50 years) compared to younger women (aged below 50 years). the differences were clearly visible in obese women. Homocysteine levels decreased after the 9-month training program. A single exercise performed every three months during the training program resulted in an increase in homocysteine levels or no changes. Conclusions. Higher homocysteine levels in the blood after a single exercise are likely caused by faster metabolism of this amino acid. Exercise of moderate intensity leads to a decrease in homocysteine levels in the blood, especially in obese women. regular physical activity should therefore be recommended not only to prevent and treat obesity but, most importantly, atherosclerosis.

The effect of chronic exercise (forced swimming) on vitamin B-6 status and metabolism was studied in growing male rats fed deficient (0 mg pyridoxine-HCl/kg), suboptimal (2 mg pyridoxine-HCl/kg) or control (7 mg pyridoxine-HCl/kg) diets for 9 wk. Sedentary rats were fed the same diets. Body weight gain was lower in deficient rats than in both other dietary groups. Sedentary rats were heavier than trained rats of all diet groups. Erythrocyte aspartate aminotransferase, urinary 4-pyridoxic acid excretion, blood (plasma and erythrocytes) and tissue B-6 vitamers were measured. Urinary 4-pyridoxic acid, plasma pyridoxal 5'-phosphate and erythrocyte aspartate aminotransferase values of exercised and sedentary rats responded to changes in dietary pyridoxine but were not different from one another. After 9 wk of vitamin B-6 depletion, tissue concentrations of pyridoxal 5'-phosphate and pyridoxamine 5;5'-phosphate were 41-66% and 26-49% lower, respectively, in the deficient groups than in the control groups. Larger percentage differences occurred in plasma than in tissues (95 vs. 22-66%). In liver, pyridoxal 5'-phosphate concentrations were lower, whereas pyridoxal concentrations were higher in trained than in sedentary rats. In gastrocnemius muscle, pyridoxal 5'-phosphate, pyridoxamine 5'-phosphate and total vitamin B-6 concentrations were higher in trained than in sedentary rats. Concentrations of vitamin B-6 compounds in heart, kidneys, brain and adrenals were not affected by training. On the basis of the vitamin B-6-dependent variables measured in this study, we conclude that prolonged exercise affects the metabolism of vitamin B-6, but does not increase the vitamin B-6 requirement in growing rats.
