Impact of Ramadan observance on physical activity barriers, sleep pattern, and physical fitness among non-fasting type 1 diabetes patients.

AIMS: This study aimed to explore sleep pattern, physical fitness and the barriers to physical activity (PA) during Ramadan observance among non-fasting individuals with type 1 diabetes (T1D) METHODS: Sixty-one patients with T1D (29 women, 32 men), who were non-fasting, completed pre- and during-Ramadan questionnaires, incorporating assessments such as the Barriers to PA (BAPAD1), Pittsburgh Sleep Quality Index (PSQI), and International Physical Activity Questionnaire (IPAQ). RESULTS: During Ramadan, BAPAD1 scores exhibited a non-significant increase (p=0.378). Primary barriers encompassed hypoglycaemia risk, work schedules, diabetes control, and fatigue. The PSQI scores demonstrated a significant increase (p<0.01), revealing a deteriorated sleep quality. Sleep duration decreased by 58 minutes (p<0.01), was associated with later bedtimes and awakenings. PA levels notably decreased (p=0.042), particularly in vigorous activities (p=0.017), while sedentary time witnessed a significant increase (p=0.008). CONCLUSION: Ramadan observance did not affect barriers to PA in individuals with T1D despite alteration of sleep pattern and PA practice. lifestyle alterations induced by Ramadan observance significantly impact individuals with T1D who are not fasting, resulting in reduced PA, shortened sleep duration, and increased sedentary time.

Antioxidant status and oxidative stress at rest and in response to acute exercise in judokas and sedentary men.

It is well recognized that acute strenuous exercise is accompanied by an increase in free-radical production and subsequent oxidative stress, in addition to changes in blood antioxidant status. Chronic exercise provides protection against exercise-induced oxidative stress by upregulating endogenous antioxidant defense systems. Little is known regarding the protective effect afforded by judo exercise. Therefore, we determined antioxidant and oxidative stress biomarkers at rest and in response to acute exercise in 10 competitive judokas and 10 sedentary subjects after mixed exercise (anaerobic followed by aerobic). The subjects performed a Wingate test, followed by 30 minutes of aerobic exercise performed at 60% of maximal aerobic power. Blood samples were taken, by an intravenous catheter, at rest (R), immediately after the physical exercise (P0), and at 5 (P5), 10 (P10), and 20 (P20) minutes postexercise. The measured parameters included the activity of the antioxidant enzymes superoxide dismutase, glutathione peroxidase, and glutathione reductase, in addition to α-tocopherol, and total antioxidant status. Malondialdehyde was measured as a representation of lipid peroxidation. At rest, the judokas had higher values for all antioxidant and oxidative stress markers as compared to the sedentary subjects (p < 0.05). Plasma concentrations of all parameters except for α-tocopherol increased significantly above resting values for both the judokas and sedentary subjects (p < 0.05) and remained elevated at 20 minutes postexercise. A significant postexercise decrease was observed for α-tocopherol (p < 0.05) at P20 for judokas and at P5 for sedentary subjects. These data indicate that competitive judo athletes have higher endogenous antioxidant protection compared to sedentary subjects. However, both groups of subjects experience an increase in exercise-induced oxidative stress that is not different.
