The Effect of Respiratory Muscle Training on Aerobic and Anaerobic Strength in Adolescent Taekwondo Athletes

This study was conducted to investigate the effect of respiratory muscle training on respiratory functions and aerobic and anaerobic strength in adolescent taekwondo athletes. Between the ages of 12–17, 32 taekwondo athletes participated in the study. Participating athletes were randomly divided into two groups as ‘’experimental group’’ (n=15) and ‘’control group’’ (n=17) as to similar characteristics. The experimental group was given respiratory muscle training for 30 min with an adjustable respiratory pressure device for 3 days a week through 8 weeks period. No exercise was given to the control group with the device. A 20 meter shuttle run test was performed for aerobic capacity and a vertical jump test was performed for anaerobic strength. The inspiratory pressure was measured. After the respiratory muscle training, statistically significant difference was found in the maximum oxygen consumption capacities (MaxVO2) and anaerobic strength values (p<0.05). In the measurements of respiratory function, forced vital capacity (FVC), slow vital capacity (SVC) and maximal voluntary ventilation (MVV), significant difference was found in favor of the experimental group (p<0.05). In the measurements of inspiration pressure, the results of pressure, strength, flow, volume and energy values were significantly different in favor of the experimental group (p<0.05). Respiratory muscle training increased the aerobic and anaerobic strength capacity of the experimental group in comparison with the control group. Some of the exercises that were used in the treatment of COPD are thought to facilitate the athletes’ respiration control

FUTBOLCULARDA E VITAMINI KULLANIMININ OKSIDAN VE ANTIOKSIDAN KAPASITE ÜZERINE ETKISI

Bu &ccedil;alışmada E vitamininin futbolcularda oksidan ve antioksidan kapasite &uuml;zerine etkisinin araştırılması ama&ccedil;landı. &Ccedil;alışmada, 15 antrenmanlı futbolcudan oluşan deney grubu ve 12 erkekten oluşan kontrol grubu olmak &uuml;zere toplamda 27 erkek g&ouml;n&uuml;ll&uuml; olarak yer aldı.Fiziksel &ouml;zelliklerin belirlenmesi i&ccedil;in v&uuml;cut ağırlığı ve v&uuml;cut kitle indeksi parametrelerine bakıldı. Fizyolojik &ouml;zelliklerin belirlenmesi i&ccedil;in sistolik ve diastolik kan basıncı, kalp atım hızı ve oksijen saturasyonu değerlerine bakıldı. Total antioksidan kapasite, tiyobarbit&uuml;rik asit-reaktif substans, kreatin kinaz ve laktat dehidrojenaz aktiviteleri değerlendirildi. Gruplar arası karşılaştırmada, egzersiz &ouml;ncesi ve sonrası fiziksel ve fizyolojik bulgularda herhangi bir farklılık bulunmazken (P&ge;0.05), egzersiz &ouml;ncesi kalp atım hızında anlamlı bir farklılık bulundu (p&le;0.05). Grup i&ccedil;i ve gruplar arası karşılaştırmalarda ise, egzersiz &ouml;ncesi ve sonrası TAC, TBARS, CK ve LDH değerlerinde anlamlı bir farklılık bulunmadı (p&ge;0.05).Sonu&ccedil; olarak, antioksidan takviye sporcularda fiziksel aktivitenin tipi, s&uuml;resi ve şiddetine g&ouml;re oksidatif stresi azaltmak ve antioksidan kapasiteyi artırmak i&ccedil;in faydalı olabilir. Egzersizin vitamin ve diğer antioksidan takviyelerle desteklenmesinin, oksidan kapasiteyi azaltma ve antioksidan seviyeyi y&uuml;kseltmede etkili olabileceği d&uuml;ş&uuml;n&uuml;lmektedir.In this study,investigating the effect of vitamin E on oxidant and antioxidant capacity in football players was aimed. A total of 27 volunteer men composed of 15 trained football players as supplement group and 12 men as control group participated in the study. Body weight and body mass index parameters were taken to determine physical characteristics. Systolic and diastolic blood pressure, pulse rate and oxygen saturation values were taken to determine the physiological characteristics. Total antioxidant capacity, thiobarbituric acid reactive substances, and creatine kinase and lactate dehydrogenase activities were evaluated.In the intergroup comparison, while no difference was found in physical and physiological findings between pre- and post-exercise (P&ge;0.05), there was a significant difference in pre-exercise pulse rate (p&le;0.05). In intra- and intergroup comparisons, no significant difference was found in pre- and post-exercise TAC, TBARS, CK and LDH values (p&ge;0.05).In conclusion, antioxidant supplementation in accordance with the type, duration and intensity of physical activity may be beneficial for athletes in order to decrease oxidative stress and increase antioxidant capacity. It is thought that supporting exercises with vitamins and the other antioxidant supplements may be effective to decrease oxidant capacity and increase the antioxidant level.</p
