Öğe Effect of acute and chronic submaximal exercise on plasma renin and aldosterone levels in football players(IOS PRESS, 2011) Patlar, SuleymanThis study aimed to examine effects of acute and chronic submaximal exercise on plasma renin and aldosterone levels in football players. Seven apparently healthy, male footballer subjects took part in the study. The subjects were exercised on ergometric bicycles for 20-min at 75% of Max VO2, 3 days a week for 4 weeks. Blood samples were collected on 4 occasions: before the exercise, immediately after the exercise, as well as 2 hours and 24 hours after the exercise. Plasma renin and aldosterone levels (RIA) were measured. Exercise significantly increased plasma renin and aldosterone levels of the athletes before and after the exercise (p < 0.05). The levels at the 2nd hour following exercise dropped significantly in comparison to those immediately after the exercise (p < 0.05). Plasma values one day after the exercise were significantly lower than those after the 2nd hour (p < 0.05). Consequently, acute and 4-week chronic submaximal exercise have significant effects on plasma renin and aldosterone levels in football players (p < 0.05).Öğe Effect of Acute Submaximal Exercise on Plasma Renin and Aldosterone Levels in Sedentary People(ASIAN JOURNAL OF CHEMISTRY, 2009) Patlar, SuleymanThis study aimed to examine how acute submaximal exercise affected plasma renin and aldosterone levels in sedentary people. The study registered 7 healthy male sedentary subjects whose mean age was 23.00 +/- 1.29 years and mean body weight was 74.00 +/- 10.19 kg. Before starting the trial, the subjects were put on an A strand Bicycle Ergometer test to identify Max VO(2) and above the threshold heart rates. The subjects with above the threshold he-art rates were exercised on ergometric bicycles for 0.5 h at 70% of Max VO(2). Blood samples were collected from the subjects before beginning the experiment. Second round of blood samples were collected immediately after the exercise ended. Third and fourth rounds of blood samples were collected after 2 and 24 h of exercise, respectively. Plasma renin and aldosterone levels were measured in the collected samples (using RIA method). Renin and aldosterone levels measured immediately after exercise were significantly higher than those before exercise, as well as those 2 and 24 h after exercise (p < 0.05). Renin and aldosterone levels 2 h after exercise did not differ from pre-exercise levels. The lowest renin and aldosterone levels were found in the measurements performed 24 h after exercise (p < 0.05). Results of the study demonstrate that acute submaximal exercise brings about significant changes in renin and aldosterone levels of sedentary people.Öğe The Effect of Glycerol Supplements on Aerobic and Anaerobic Performance of Athletes and Sedentary Subjects(ACAD PHYSICAL EDUCATION-KATOWICE, 2012) Patlar, Suleyman; Yalcin, Hasan; Boyali, EkremThe purpose of this study was to evaluate the effect of glycerol supplementation on aerobic and anaerobic exercise performance in sedentary subjects and athletes. The glycerol supplement treatments were as follows: 40 volunteers were selected and divided into two groups, sedentary and exercise groups. These two groups were further subdivided into two groups. The first group, the placebo (S), only consumed water; the second group (GS) consumed glycerol followed by water. Neither of these groups did any exercise for 20 days. The third and fourth groups consisted of the exercise group subjects; they were required to perform a 20-m shuttle run test every day for 20 days. The third group's subjects, the placebo (E), only consumed water. The last group (GE) consumed glycerol followed by water. The Astrand Cycle Ergometer Test (ACET) was performed, and the Cosmed K4b(2) portable gas analysis system was used to determine the aerobic capacity, while the Wingate Anaerobic Power Test (WAPT) was performed to determine the level of anaerobic power. The 20 Meter Shuttle Run Test (20MSRT) was performed after glycerol supplementation throughout the 20 days, and the exercise periods and distances were recorded. The glycerol supplement was found to have an increasing effect on aerobic and anaerobic performance in GS, E and GE. A similar effect was found for the covered distances and time in the same groups. However, an adverse effect was found on body weight.Öğe EFFECT OF NOCTURNAL EXHAUSTION EXERCISE ON THE METABOLISM OF SELECTED ELEMENTS(INST BIOLOSKA ISTRAZIVANJA SINISA STANKOVIC, 2014) Patlar, Suleyman; Gulnar, Ubeyde; Baltaci, Abdulkerim Kasim; Mogulkoc, RasimThe present study aims to examine how exercise performed until fatigue at night affects element distribution in the serum. The study examined 10 healthy sedentary males who were not actively engaged in any particular sport and whose mean age was 23.00 +/- 0.25 years, mean height 177.79 +/- 2.25 cm, and mean weight 70.70 +/- 1.63 kg. Blood samples were collected from the subjects at midnight twice: during rest before exercise and after exercise. Serum phosphorus, sodium, potassium, sulfur (mmol/L), cobalt, boron, cadmium, chrome, nickel, manganese, molybdenum, copper, iron, zinc and calcium levels (mg/L) were measured using atomic emission spectroscopy (ICP-AES). Exhaustion exercise performed at night brought about a decrease in copper levels only (p< 0.05), while elevating levels of potassium, sodium, magnesium, calcium, iron, zinc, manganese, nickel, selenium, molybdenum, chrome, cobalt, lead and cadmium (p< 0.05). The results of the study demonstrate that nighttime exercise until exhaustion significantly alters element metabolism.Öğe Effect of Resveratrol Administration on the Element Metabolism in the Blood and Brain Tissues of Rats Subjected to Acute Swimming Exercise(HUMANA PRESS INC, 2017) Baltaci, Abdulkerim Kasim; Arslangil, Dilek; Mogulkoc, Rasim; Patlar, SuleymanThe aim of the present study is to examine how resveratrol administration affects the element metabolism in the blood and brain cortex tissues of rats subjected to an acute swimming exercise. The study was carried out on Wistar-Albino-type adult male rats supplied by the Center. Group 1 is the control group. Group 2 is the swimming control group. Group 3 is the resveratrol (10 mg/kg/day) + swimming group. Group 4 is the resveratrol (10 mg/kg/day) group. Blood and brain cortex tissues were analyzed for some elements. The acute swimming exercise led to increases in the rats' serum iron, selenium, lead, cobalt, and boron levels, while the resveratrol-swimming group has increases in copper, phosphorus, and calcium values. The brain cortex tissue of the resveratrol-swimming group had significantly higher molybdenum levels than others. The results obtained in the study indicate that acute swimming exercise altered the distribution of elements in the serum to a considerable extent; however, resveratrol's affect is limited. Especially, resveratrol supplementation may have a regulatory affect on serum iron and magnesium levels.Öğe Effect of vitamin A administration on free radicals and lactate levels in individuals exercised to exhaustion(UNIV KARACHI, 2016) Patlar, Suleyman; Baltaci, Abdulkerim Kasim; Mogulkoc, RasimThis study was performed to explore the effect of vitamin A administration on Free Radicals production and antioxidant system activity and lactate levels in individuals exercised to exhaustion The study registered 10 healthy sedentary males their mean age was 22,85+/-0,26 years. The subjects were orally administrated with 300 mg vitamin A (retinol) for 4 weeks and engaged in strenuous exercise (using the Bruce protocol) once a week. Blood samples were collected from the subjects at four different times, before and after the supplementation and before and after exercise to analyze Malondialdehyde (MDA), Nitric oxide (NO), Glutathione (GSH), Glutathione peroxidase (GSH-Px), Catalase (CAT), Superoxide dismutase (SOD) levels using colorimetric ELISA test kits and plasma lactate levels using an autoanalyzer. Exhaustion exercise leaded to an increase in both MDA, NO, and lactate, and GSH, GSH-Px, CAT and SOD levels compared to resting levels both before and after supplementation (p<0.05). Increased NO levels found in pre-supplementation exhaustion showed a significant decrease after the supplementation of vitamin A (p<0.05), but the other parameters were not changed after vitamin A administration. The results of our study demonstrate that the increase caused by 4-week strenuous exercise in the levels of the free radical NO was offset by vitamin A supplementation. It can be suggested that supplementation of vitamin A at physiological doses has a limited effect on lipid peroxidation caused by strenuous exercise.Öğe The Effect of Vitamin A Supplementation on Various Elements in Elite Taekwondo Players(HUMANA PRESS INC, 2011) Patlar, Suleyman; Boyali, Ekrem; Baltaci, Abdulkerim Kasim; Mogulkoc, RasimThe present study aims to examine the effects of both physical activity and vitamin A supplementation on trace element metabolism in individuals engaged in taekwondo. The study registered seven healthy male national taekwondo players whose mean age was 21.86 +/- 0.34 years and mean weight was 64.86 +/- 2.72 kg. The subjects were supplemented with oral administration of 100 mg vitamin A (retinol) for 6 weeks, and concurrently, they were subjected to taekwondo training 5 days a week. Before starting the vitamin A supplementation, blood samples were taken from the subjects twice, once at rest and once after exhaustion. Similarly, at the end of the 6-week vitamin A supplementation, two blood samples were taken from the subjects, once at rest and once after exhaustion, in order to determine (by atomic emission) and compare serum cobalt, molybdenum, calcium, cadmium, chromium, copper, manganese, sodium, nickel, phosphorus, sulfur, iron, boron, and zinc (mg/L) levels. Values of boron and nickel dropped significantly after 6-week vitamin A supplementation (p < 0.001). Reduced levels of boron and nickel we obtained in the present study are believed to result from the antioxidant effect of long-term vitamin A supplementation.Öğe Effect of Vitamin C Supplementation on Lipid Peroxidation and Lactate Levels in Individuals Performing Exhaustion Exercise(ANNALS APPLIED SPORT SCIENCE, 2017) Patlar, Suleyman; Baltaci, Abdulkerim Kasim; Mogulkoc, Rasim; Gunay, MehmetBackground. Exercise has significant affects on free radical production. Objective. The objective of the present study was to explore the effect of vitamin C supplementation on lipid peroxidation and lactate levels in sedentary individuals who performed exhaustion exercised. Methods. 10 healthy sedentary male athletes participated to study. They were supplemented with 300 mg oral vitamin C (L-ascorbic acid, Ester-C Plus 500 mg, Solgar-USA) and subjected to acute exhaustion exercise by fatigue developed one time a week for 4 weeks. Exhaustion exercises were carried out until exhaustion developed according to Bruce protocol once a week for 4 weeks. Blood samples were collected from the subjects four times, at the beginning and at the end of the supplementation and before and after exercise, over the 4-weeks study period. The samples were used to analyze MDA, GSH, GSH-Px, CAT, SOD and NO levels by using ELISA colorimetric method and plasma lactate levels by an autoanalyzer device. Results. Exhaustion MDA, GSH, GSH-Px, CAT, SOD and NO levels measured both before and after supplementation were higher than resting levels (p<0.05). MDA, NO and lactate levels that were elevated in exhaustion before supplementation decreased significantly after vitamin C supplementation (p<0.05). Conclusion. The results of our study indicate that the increase in free radical production and lactate levels due to by 4-week exhaustion exercise were offset by vitamin C supplementation. It can be argued in conclusion that supplementation of physiologic doses of vitamin C may be useful for athlete health and performance.Öğe EFFECTS OF DIURNAL AND NOCTURNAL STRENUOUS EXERCISE ON SERUM MELATONIN LEVELS(SOC BRASILEIRA MED ESPORTE, 2016) Kilic, Mehmet; Demirhan, Bilal; Patlar, Suleyman; Baltaci, Abdulkerim Kasim; Mogulkoc, RasimIntroduction: There are reports of a possible relationship between melatonin, a hormone secreted by the pineal gland, and exercise. Objective: The present study aims to investigate how diurnal and nocturnal strenuous exercise affects melatonin levels. Methods: The study enrolled 10 healthy sedentary males who did not actively exercise. The subjects had a mean age of 22.20 +/- 0.24 years, a mean height of 174.60 +/- 2.33 cm, and a mean weight of 69.70 +/- 2.42 kg. Two blood samples were collected from the subjects, one at rest, at 10:00 am, and the other immediately after strenuous exercise. Likewise, blood samples were taken from the same group of subjects after 48 hours: at 24:00 hours at rest and immediately after strenuous exercise. Samples were analyzed using the ELISA method to determine the serum melatonin levels (pg/ml). Results: By comparing the values at rest and after exercise, it was found that serum melatonin values remained unchanged with exercise. Serum melatonin values at rest or post-exercise measured at night were higher when compared with those measured during the day (p<0.05). Conclusions: Higher levels of melatonin found in the study appear to result from the increased release of melatonin at night, and not from exercise. The results of this study indicate that strenuous exercise carried out day or night, did not significantly influence serum melatonin levels.Öğe Elements in Sera of Elite Taekwondo Athletes: Effects of Vitamin E Supplementation(HUMANA PRESS INC, 2011) Patlar, Suleyman; Boyali, Ekrem; Baltaci, Abdulkerim Kasim; Mogulkoc, Rasim; Gunay, MehmetMany researchers have emphasized the relation between nutrition and development and sustaining performance. Two methods are commonly employed to identify the interaction between physical activity and nutrition. The first consists of administering food with a variety of contents to people engaged in physical activity and observing their performance responses, and the other is concerned with determining the effects of physical activity on nutrition. Therefore, it can be said that there has been a growing interest in the explorations into the relation between exercise and vitamins, minerals, and elements. The present study reports the effects of 6 weeks administration of 300 mg/day vitamin E on the distribution of serum elements in elite taekwondo athletes. Seven male athletes, mean ages 22.1 +/- 0.5 years weighing on average 66.4 +/- 2.4 kg were included in the study. The athletes had been practicing taekwondo for 10-12 years. Resting blood samples were collected in duplicate before and after supplementation for determination of serum levels of cobalt, boron, cadmium, chromium, nickel, manganese, sulfur, copper, iron, zinc, phosphorus, sodium, potassium, and calcium. Supplementation resulted in significant increases of all elements relative to values before supplementation (p < 0.001), with the exception of boron and sulfur, which remained without change. The results of the present study demonstrate that vitamin E supplementation crucially influences the element and mineral metabolism in elite athletes.Öğe Melatonin has a protective effect against lipid peroxidation in the bone tissue of diabetic rats subjected to acute swimming exercise(WALTER DE GRUYTER GMBH, 2018) Bicer, Mursel; Baltaci, Saltuk Bugra; Patlar, Suleyman; Mogulkoc, Rasim; Baltaci, Abdulkerim KasimAim: The present study aimed to examine the effects of melatonin supplementation on lipid peroxidation in the bone tissue of diabetic rats subjected to acute swimming exercise. Methods: The study was conducted on 80 Sprague-Dawley type adult male rats which were equally allocated to eight groups: group 1, general control; group 2, melatonin-supplemented control; group 3, melatonin-supplemented diabetic control; group 4, swimming control; group 5, melatonin-supplemented swimming; group 6, melatonin-supplemented diabetic swimming; group 7, diabetic swimming; group 8, diabetic control. In order to induce diabetes, the animals were subcutaneously injected with 40 mg/kg streptozotocin (STZ). The animals were supplemented with 3 mg/kg/day melatonin intraperitoneally (IP) for 4 weeks. At the end of the study, the animals were decapitated to collect bone tissue samples which were examined to find out the malondialdehyde (MDA) (nmol/g/protein) and glutathione (GSH) (mg/dL/g protein) levels. Results: The highest MDA values in the bone tissue were found in groups 7 and 8. MDA levels in the bone tissue in groups 3 and 6 were lower than the levels in groups 7 and 8, but higher than those in all other groups. Groups 3, 5 and 6 had the highest bone tissue GSH values. On the other hand, the lowest GSH level was established in groups 7 and 8. Conclusion: The results of the present study indicated that the cell damage caused by acute swimming exercise and diabetes in the bone tissue could be prevented by melatonin supplementation.
