Objective: To evaluate Turkey according to the number of work accidents, occupational diseases and related mortality rates, insured workers, establishments and cities, which are important issues in terms of showing countries' situation.

ÖzAerobik kapasite, dışarıdan alınan oksijeni iskelet kaslarına iletme kapasitesidir. Aerobik kapasite için en iyi ve en güvenilir ölçüt, kademeli artan bir test protokolüyle ölçülen maksimum oksijen tüketimidir (VO 2maks ). VO 2maks değeri submaksimal ve maksimal egzersiz testlerinde indirekt ve direkt yöntemle ölçülebilir. Genetik, yaş, cinsiyet, aktivite seviyesi, vücut kitle indeksi ve egzersiz modu VO 2maks değerine etki eden faktörler arasında sayılabilir. Oksijenin kaslara iletimindeki tüm basamaklarda VO2maks üzerinde sınırlandırıcı etki yapabilecek faktörler olup bunların en etkilisi maksimal kalp debisidir. Bilişsel performans, zihnin deneyim veya öğrenme ile edinilen bilgiyi işleme ve değerlendirme yeteneği olup inhibitör kontrol, işlem hızı, çalışan bellek, bilişsel esneklik, görsel-uzamsal işlem, problem çözme ve öğrenme gibi farklı bilişsel fonksiyonları içerir. Aerobik aktivite, zihinsel sağlığın gelişimi ve serebral yapısal değişiklikler için güçlü bir uyarıcıdır. Bu derlemede aerobik kapasitenin ve bu kapasiteyi artırıcı egzersiz seviyesinin bilişsel fonksiyonlarla olan ilişkisi irdelenmiştir. Anahtar Sözcükler: aerobik kapasite; bilişsel performans; egzersiz; maksimum oksijen tüketimi Abstract Aerobic capacity is the capacity to deliver oxygen from the outside to the skeletal muscles. The best and most reliable criterion for aerobic capacity is the maximum oxygen consumption (VO 2max ), which is measured using a progressive test protocol. VO 2max can be measured by the indirect and direct methods in submaximal and maximal exercise tests. Genetics, age, sex, activity level, body mass index, and exercise mode can be counted as factors affecting VO 2max . All steps in the delivery of oxygen to the muscles include factors that may have a limiting effect on VO2max, the most effective of which is the maximal cardiac output. Cognitive performance is the mental ability to process and evaluate the knowledge acquired through experience or learning, and involves different cognitive functions such as inhibitory control, processing speed, working memory, cognitive flexibility, visual spatial processing, problem solving, and learning. Aerobic activity is a powerful stimulus for improving the mental health and the structural changes in the brain. This review addresses the relationship between cognitive functions and aerobic capacity and the level of cognitive performance-increasing exercise.

The positive relationship between aerobic capacity and cognitive performance is well known, but there is little information regarding young adults. Therefore, we aimed to test the hypothesis that aerobic capacity (VO 2max ) correlates with cognitive and academic performance in medical students who have higher academic achievement with academic performance. We included 65 volunteer medical students who were in term 2/6 in this descriptive, cross-sectional study. Body composition and the International Physical Activity Questionnaire and cardiopulmonary exercise test results of all participants were analyzed. Lumosity application with 6 categories of cognitive tests was applied to evaluate cognitive performance. The university entrance exam scores of the students were taken into consideration to assess their academic performance. We observed a significant "positive" relationship between aerobic capacity and some domains of cognitive performance, especially problem solving (p < 0.05), but we did not find a significant relationship between aerobic capacity and academic performance. Consequently, although we confirmed the existence of a positive effect of high aerobic capacity on cognitive performance stated in the literature, we couldn't confirm this for all cognitive domains or academic performance. These results suggest that more comprehensive studies on this subject are needed.
