Tip 2 Diyabet Hastaları İçin Kan Şekeri Düzeylerinde Daha Fazla İyileşme İçin Ne Zaman Egzersiz Yapmalı?

Brigham and Women’s Hospital ve Joslin Diabetes Center’dan araştırmacılar tarafından yapılan bir araştırma, öğleden sonra fiziksel aktivitenin tip 2 diyabet hastalarında kan şekeri kontrolünü önemli ölçüde iyileştirebileceğini öne sürüyor. Ekip, Look AHEAD çalışmasından elde edilen verileri kullanarak, öğleden sonraları en aktif olanların kan şekerini en fazla düşürdüğünü ve diyabet ilaçlarını bırakma olasılıklarının en yüksek olduğunu buldu.

Look AHEAD çalışmasının bir analizinde, Brigham ve Joslin Diyabet Merkezi’nden araştırmacılar, öğleden sonra fiziksel olarak aktif olan katılımcıların kan şekerinde günün diğer saatlerinde en aktif olanlara göre daha fazla düşüş olduğunu buldular.

37 milyondan fazla Amerikalı diyabet hastasıdır ve bu nüfusun %90-95’ine tip 2 diyabet teşhisi konur. Sağlıklı beslenme ve düzenli fiziksel aktivite programı gibi yaşam tarzı müdahaleleri, diyabeti yönetme yöntemleridir. Mass General Brigham sağlık sisteminin kurucu üyelerinden Brigham and Women’s Hospital’daki araştırmacılar ile Beth Israel Lahey Health’in bir parçası olan Joslin Diyabet Merkezi’ndeki araştırmacıların ortak çalışmasıyla yapılan yeni bir çalışma, Look AHEAD’den (Action for Health in Diabetes) alınan verileri kullanıyor. çalışma, tip 2 diyabet ve aşırı kilolu veya obezite teşhisi konan hastalarda yoğun bir yaşam tarzı müdahalesini diyabet desteği ve eğitimi ile karşılaştıran randomize kontrollü bir çalışma.[{” attribute=””>cardiovascular disease over time. In the current study, the research team assessed whether physical activity at certain times of day was associated with greater improvement in blood glucose control. Their findings suggest patients with type 2 diabetes who were physically active in the afternoon had the largest improvements after one year in the trial. The team’s results are published in Diabetes Care.

“In this study, we shown that adults with type 2 diabetes had the greatest improvement in glucose control when they were most active in the afternoon,” said co-corresponding author Jingyi Qian, PhD, from the Division of Sleep and Circadian Disorders at the Brigham. “We’ve known that physical activity is beneficial, but what our study adds is a new understanding that timing of activity may be important too.”

Physicians recommend that patients with diabetes participate in regular physical activity as a method to manage their blood glucose levels. Elevated blood glucose levels can put people with type 2 diabetes at risk of heart disease, vision impairment, and kidney disease.

The team analyzed physical activity data from the first and fourth years of the Look AHEAD study, which included data from over 2,400 participants. During the study, participants wore a waist accelerometry recording device to measure physical activity. When the Brigham and Joslin team reviewed the data from year 1, they determined that those who engaged in moderate-to-vigorous physical activity in the afternoon had the greatest reduction in blood glucose levels. Upon comparing the data from year 4, the afternoon group maintained a reduction in blood glucose levels. In addition, the afternoon group also had the highest chance of stopping their glucose-lowering/diabetes medications.

The Brigham and Joslin team note that their investigation has limitations; for example, their study is observational and does not measure confounding factors like sleep and dietary intake.

In future studies, the team may test their findings experimentally to investigate the underlying mechanisms that may explain why time of day of activity may influence blood glucose control. From this, the team may be able to provide specific physical activity recommendations for patients.

“Timing does seem to matter,” said co-corresponding author Roeland Middelbeek, MD, assistant investigator at Joslin Diabetes Center. “Going forward, we may have more data and experimental evidence for patients to give more personalized recommendations.”
