“…To our knowledge, this is the first report of an inverse relationship between VO2 max and hypoglycaemia risk during exercise but not in the post‐exercise period. We believe that our observation is counter‐intuitive as individuals with good fitness levels should be used to performing physical activity and may be more accustomed to preventing hypoglycaemia compared with those with a poor fitness level; however, it has recently been reported that fitness plays a role in glucose fluctuations among adolescents with Type 1 diabetes . Fitness level was evaluated in association with mean amplitude of glycaemic excursion index for measuring glucose fluctuations, especially hyperglycaemia.…”

“…Fitness level was evaluated in association with mean amplitude of glycaemic excursion index for measuring glucose fluctuations, especially hyperglycaemia. Fitness level was inversely correlated with mean amplitude of glycaemic excursion (r = -0.46) [15]; thus higher fitness may be associated with higher hypoglycaemic risk during exercise. Exercise-associated hypoglycaemia results from many factors including an inability to match reduced insulin needs during exercise, improved insulin sensitivity [16], impaired glucagon secretion [6,16] and counter-regulatory hormonal failure [16].…”

“…12 Hipoglisemi, insülin veya insülin sekretagogları ile tedavi edilen diyabetiklerde egzersiz ile ilişkili potansiyel bir problemdir. Hipoglisemi, egzersiz sırasında, egzersizden hemen sonra veya birkaç saat 17 Ancak, insülin uygulamasındaki agresif azalmalar veya atlanan bir insülin dozu nedeni ile düşük insülin konsantrasyonları, aerobik egzersiz öncesi ve sırasında hiperglisemiye neden olabilir. 15 Direnç egzersizinin, sürekli orta şiddette aerobik egzersize göre daha iyi glukoz stabilitesi ile ilişkili olduğu, ancak bazı kişilerde glukoz seviyelerinin ılımlı yükselmesine neden olabileceği belirtilmektedir.…”

Ö ÖZ ZE ET T Diyabetli bireylerin tedavisinde tıbbi beslenme tedavisi ve egzersiz, yaşam tarzı değişikliklerinin temelini oluşturmaktadır. Egzersizin olası komplikasyonlarının önlenmesi için egzersiz öncesi, sırası ve sonrasında egzersizin tipi, süresi ve yoğunluğuna göre beslenme planının yapılması gerekmektedir. Egzersiz, fiziksel uygunluğu artırmak için yapılandırılmış ve tasarlanmış daha spesifik bir fiziksel aktivite şeklidir. Egzersizin kan şekeri kontrolünü iyileştirdiği, kardiyovasküler risk faktörlerini azalttığı, kilo kaybına katkıda bulunduğu ve kişilerin daha iyi hissetmesini sağladığı gösterilmiştir. Tip 1 diyabetli kişiler tarafından yapılan çeşitli egzersiz türlerine metabolik ve nöroendokrin tepkilerinin anlaşılması, uygun beslenme ve insülin yönetimi stratejilerinin belirlenmesi için gereklidir. Tip 1 diyabette, egzersize verilen glisemik cevaplar, insülinin uygulandığı yer, dolaşımdaki insülin miktarı, egzersiz öncesi kan glukoz konsantrasyonu, son öğün veya atıştırmanın bileşimi ve yoğunluğu ile faaliyetin süresi ile ilişkilidir. Egzersiz sırasında dolaşımdaki artan insülin konsantrasyonları, hepatik glukoz üretimine göre artan glukoz atılımını teşvik eder ve lipolizi geciktirebilir. Kasların bir yakıt olarak glukoza bağımlılığını artırmaktadır. Hipoglisemi çoğu hastada aerobik egzersize başladıktan yaklaşık 45 dk içerisinde gelişmektedir. Tip 1 diyabetli hem antrenmanlı hem de antrenmansız bireylerin, aerobik egzersize başlamadan önce karbonhidrat alımını arttırmaları veya insülin dozunu azaltmaları veya her ikisini de uygulamaları gerekmektedir. Diyabetli birçok birey için, tedavi planının en zor olan kısmı ne yiyeceğini belirlemek ve bir yemek planını takip etmektir. Beslenme tedavisinin genel diyabet yönetiminde ayrılmaz bir rolü vardır ve diyabetli her birey, kişiselleştirilmiş bir beslenme planının iş birliğine dayalı gelişimi de dâhil olmak üzere sağlık ekibiyle birlikte eğitim, öz yönetim ve tedavi planlaması ile aktif olarak ilgilenmelidir.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Tip 1 diabetes mellitus; egzersiz; beslenme A AB BS S T TR RA AC CT T Medical nutrition therapy and exercise form the basis of lifestyle changes in the treatment of people with diabetes. In order to prevent possible complications of exercise, nutrition plan should be prepared according to type, duration and intensity of exercise before, during and after exercise. Exercise has been shown to improve blood sugar control, reduce cardiovascular risk factors, contribute to weight loss, and make people feel better. Understanding metabolic and neuroendocrine responses to various types of exercise performed by people with Type 1 diabetes is essential to identify appropriate nutritional and insulin management strategies. In Type 1 diabetes, glycemic responses to exercise are associated with the location of insulin delivery, the amount of circulating insulin, blood glucose concentration before exercise, the composition and intensity of the last meal or snack, and the duration of the activity.

“…Fear of hypoglycemia among adolescent type I diabetics induces low levels of exercise although this activity is an important aspect of disease management [49] [50]. Nevertheless, physical exercise provides a recipe for glycemic control among these patients [51]- [53]. In a study of 19 type I diabetics aged 14 -20 years, with average fitness, and adiposity, meeting the Federal guideline of 60 min daily moderate-to-vigorous intensity physical exercise, Metcalf and colleagues [54] observed that hypoglycemia was 31% more likely among those adolescents who had accumulated 30 minutes/day more moderate-to-vigorous intensity physical exercise in the previous afternoon than those who had accumulated less.…”

Physical exercise, whether aerobic, endurance or resistance types, plays a central role in establishing and maintaining the integrity of the brain and central nervous system (CNS). When exercise is adhered to in conjunction with selective food/drink intake and dietary restriction, it promotes neurohealth. In this article, we review the interactions of age and gender, as well as insulin and diabetes, with exercise, individuals' cognitive-affective status and its interactions with exercise propensity, all of which modulate the eventual outcomes of the influence of exercise upon parameters of neurohealth. The combination of exercise with dietary restriction provides numerous factors pertaining to psychological, neurochemical and anti-pathological manifestations of neurophysiological resilience even through aging. The challenge evoked by the exercise-diet combination in the body mobilizes a multitude of adaptive cellular stress-response signaling pathways in neurons involving neurotrophic factors, anti-inflammatory cytokines, DNA-repair proteins, macroautophagy, and mitochondrial biogenesis.
