Öğe Adrenocorticotropic hormone and cortisol levels in athletes and sedentary subjects at rest and exhaustion: Effects of magnesium supplementation(HUMANA PRESS INC, 2008) Cinar, Vedat; Mogulkoc, Rasim; Baltaci, Abdulkerim Kasim; Polat, YahyaThe effects of a 1-month exercise program and magnesium supplementation on the adrenocorticotropic hormone and cortisol levels were studied in young tae-kwon-do and sedentary subjects both at rest and exhaustion. The hormone levels were compared before and after supplementation with 10 mg of magnesium (as magnesium sulfate) per kilogram of body weight. Both exercise and magnesium supplements caused significant increases of the adrenocorticotropic hormone (p < 0.05). The cortisol levels were increased in training subjects receiving supplements (p < 0.05) but not so in subjects that either trained or received magnesium supplements in an independent manner. The cortisol levels measured in resting individuals were higher in the supplemented and non-supplemented athletes than those in sedentary subjects (p < 0.05). The results of this study show that exercise and/or magnesium supplementation causes a rise of the adrenocorticotropic hormone, whereas cortisol is increased only as a result of combined exhaustion and magnesium supplements.Öğe Çabuk kuvvet ve sprint antrenmanlarının reaksiyon zamanına etkisi(Selçuk Üniversitesi Sağlık Bilimleri Enstitüsü, 2000) Polat, Yahya; Akkuş, HasanAraştırmanın amacı çabuk kuvvet ve sprint antrenmanlarının reaksiyon zamanına etkisinin tespit edilmesidir. Araştırma, yaşlan 18-24 arasında değişen, Beden Eğitimi ve Spor Yüksekokulunda okuyan 24 erkek öğrenci üzerinde yapılmıştır. Deneklerin yaş ortalamaları çabuk kuvvet grubunda 21.75 ± 1.21 yıl, sprint grubunda 21.75 ± 1.42 yıl olarak tespit edilmiştir. Boy ortalamaları çabuk kuvvet grubunda 1.78 + 0.06 cm, sprint grubunda ise 1.75 ± 0.46 cm olarak belirlenmiştir. Çalışmalarda 8 hafta süresince, haftada 3 gün ( Pazartesi- Çarşamba-Cuma) ve 60 dk olacak şekilde yapılmıştır. Denekler rastgele iki gruba ayrılarak, birinci grup (Çabuk kuvvet grubu) BESYO ağırlık salonunda % 50- 75- 100 şiddetinde 6 tekrarlı maksimal yüklenme yöntemine göre çalıştırılmıştır. İkinci grup (sprint grubu ) ise BESYO Olimpik stadı parkurunda %100 şiddette sprint çalışmıştır. Setler arasında nabızın 120'ye, tekrarlar arasında ise 140 atım dakikaya düşünceye kadar beklendi. Denekler antrenman öncesi ve antrenman sonrası olmak üzere iki ölçüme tabi tutulmuştur. Bu. ölçümlerde deneklerin vücut ağırlığı, relatif pençe, relatif bacak,relatif sırt, anaerobik güç, 3 0m sprint, yağ yüzdesi, sese karşı sağ el, sese karşı sol el ZR, sese karşı sağ ayak, sese karşı sol ayak, ışığa karşı sağ el, ışığa karşı sol el, ışığa karşı sağ ayak, ışığa karşı sol ayak reaksiyon süreleri ölçüldü. Gruplar arası ve Öntest-sontest arasındaki farklılığın tespiti için "t" testi kullanıldı. İki grup arasında vücut ağırlığı ve anaerobik güç parametrelerinde anlamlı bir fark bulunmuştur (P<0.05). Diğer parametrelerde ise anlamlı bir fark bulunamamıştır (P>0.05). Çabuk kuvvet grubunda öntest ve sontest arasındaki karşılaştırılmada vücut ağırlığı, relatif pençe, relatif bacak, relatif sırt, anaerobik güç ve 3 Om sprint, vücut yağ yüzdesi parametrelerinde, sese karşı sağ el, sese karşı sol el ZR, sese karşı sağ ayak, sese karşı sol ayak, ışığa karşı sağ el, ışığa karşı sol el, ışığa karşı sağ ayak, ışığa karşı sol ayak reaksiyon sürelerinde anlamlı fark bulunmuştur (PO.05). Sprint grubunda öntest ve sontest karşılaştırılmasında ise vücut ağırlığı, relatif pençe, relatif bacak, relatif sırt, anaerobik güç ve 3 Om sprint, vücut yağ yüzdesi parametrelerinde ve sese karşı sol el ZR, sese karşı sağ ayak, sese karşı sol ayak, ışığa karşı sağ el, ışığa karşı sol el, ışığa karşı sağ ayak, ışığa karşı sol ayak reaksiyon sürelerinde anlamlı fark bulunmuştur (P<0.05). Sonuç olarak, deneklerde çabuk kuvvet ve sprint antrenman metodunun reaksiyon zamanı üzerinde birbirine yakın olumlu etkiye sahip olduğu belirlenmiştir.Öğe The effect of magnesium supplementation on glucose and insulin levels of Tae-kwan-do sportsmen and sedentary subjects(UNIV KARACHI, 2008) Cinar, Vedat; Polat, Yahya; Mogulkoc, Rasim; Nizamlioglu, Mustafa; Baltaci, Abdulkerim KasimThis study was performed to determine how the magnesium supplementation for a 4-week period affects the glucose and insulin levels at rest and at exhaustion in sportsmen. This is a 4 week study performed on 30 healthy male subjects varying between 18-22 ages. Subjects were separated into 3 groups. 1st group; group supplemented with magnesium, 2nd group; Magnesium supplementations +exercise group, 3rd group; training group. Glucose and insulin parameters of the groups were measured 4 times; at rest and exhaustion in the beginning of the research and at rest and exhaustion after the end of 4 weeks application period. Glucose levels in exhaustion measurements both before and after the supplementation significantly increased compared to resting levels (p<0.05). Significant difference was determined in the glucose values of 1st and 2nd groups supplemented with magnesium in comparison to their first measurements (p<0.05). Insulin values a decrease in all of the 3 groups occurred with exercise both before and after the supplementation (p<0.05). Magnesium supplementation has an important effect on glucose levels whereas it has no effect on insulin levels.Öğe Effects of Magnesium Supplementation on Testosterone Levels of Athletes and Sedentary Subjects at Rest and after Exhaustion(HUMANA PRESS INC, 2011) Cinar, Vedat; Polat, Yahya; Baltaci, Abdulkerim Kasim; Mogulkoc, RasimThis study was performed to assess how 4 weeks of magnesium supplementation and exercise affect the free and total plasma testosterone levels of sportsmen practicing tae kwon do and sedentary controls at rest and after exhaustion. The testosterone levels were determined at four different periods: resting before supplementation, exhaustion before supplementation, resting after supplementation, and exhaustion after supplementation in three study groups, which are as follows: Group 1-sedentary controls supplemented with 10 mg magnesium per kilogram body weight. Group 2-tae kwon do athletes practicing 90-120 min/day supplemented with 10 mg magnesium per kilogram body weight. Group 3-tae kwon do athletes practicing 90-120 min/day receiving no magnesium supplements. The free plasma testosterone levels increased at exhaustion before and after supplementation compared to resting levels. Exercise also increased testosterone levels relative to sedentary subjects. Similar increases were observed for total testosterone. Our results show that supplementation with magnesium increases free and total testosterone values in sedentary and in athletes. The increases are higher in those who exercise than in sedentary individuals.Öğe Examination on the anthropometric features and somatotypes of the male children at the age of 16(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2011) Polat, Yahya; Biçer, Mürsel; Patlar, Süleyman; Akil, Mustafa; Günay, Mehmet; Çelenk, ÇağrıObjectives.-The aim of the study is to examine the anthropometric values and the somatotypes of male children from different branches in physical education lessons and regular movement training. Methods.-Two hundred and eighteen volunteer subjects at the age of 16, namely, 68 soccer players, 89 persons practising fitness and 70 sedentary have participated in the study. In the research, sitting height, crawl length, body width parameters, body environment and sonnatotypic parameters of the subjects are measured. In this work, the highest humeral width value is achieved by the soccer group, where it is found to be no different from the fitness group (P > 0.05) and to be significantly higher than the sedentary group (P < 0.05). When femur width parameter is examined, it is determined that the soccer group is higher than the other two groups and that the fitness group is significantly higher than the sedentary group. In the study, while the highest endomorph value is obtained from sedentary group, it is found to be significantly higher than the other two groups (P < 0.05). While the highest mesomorph value is achieved from soccer group and the lowest value is achieved from sedentary group, it is determined that each of these three groups is significantly different from one another (P < 0.05). While the highest ectomorph value is achieved from fitness group (P < 0.05), it is found to be significantly higher than the other two groups (P < 0.05). Conclusions.-Consequently, it can be said that the soccer players have more optimal dimension, environment and somatotypical structure when compared to those practising fitness and the sedentary group (P < 0.05).
