The aim of this study was to correlate glycemic control (GC) and variables of physical activity levels (PAL) in children with type 1 diabetes mellitus (T1DM).
Fifty children and adolescents with T1DM were selected. Personal and medical data for the patients were collected. Physical evaluations of body weight and sexual maturation were undertaken. Bouchard’s questionnaire was applied to evaluate PAL as well as for time spent on physical activities.
Sixty-four percent of the subjects were sexually mature. Differences were observed between females and males in insulin dose, duration of light physical activity, and sleeping time (P < .05). Ninety percent presented poor GC and 80% had a low PAL. Fasting blood glucose (FBG) was significantly correlated with PAL, with sedentary time, and with sleeping time. Glycated hemoglobin (HbA1c) was significantly correlated with sedentary time and sleeping time. Among the three groups of PAL (insufficient × moderate × active) there were differences in HbA1c (%), FBG (mg/dL), duration of disease (years), and insulin dose (UI/kg/day) (P < 0.001).
GC was significantly correlated with PAL. Among the three groups of physical activity level, the most active group was seen to have the best GC.

The majority of schoolchildren with asthma do not participate in regular physical activity due to a risk of exercise-induced asthma. The aim of the study was to determine the glycemic characteristic of Taiwanese children with persistent asthma. The current study found that children with asthma (age 10.4 ± 0.4 years) exhibited lower whole-body insulin sensitivity and poorer physical fitness compared to children without asthma (age 10.9 ± 0.6 years). Postprandial glucose and insulin, BMI, and waist circumference of the children with asthma were greater than those of the healthy children. Four patients with asthma regularly participating in a permissible amount of physical activity exhibited lower postprandial glucose and insulin levels compared to those of the rest of the children with asthma who were totally lacking physical activity. A permissible amount of physical activity appears to be beneficial for children with asthma in the prevention of the early onset of insulin resistance.

Polycystic ovarian syndrome (PCOS) affects 18–22% women of reproductive age. We conducted a systematic review and meta-analysis to quantify expected benefits of lifestyle (exercise and dietary) interventions on various clinical outcomes in PCOS.
Potential studies were identified by conducting systematic search of PubMed, the Cumulative Index to Nursing and Allied Health Literature, and Cochrane controlled trials registry (1966 to April 2013) using key concepts of PCOS, exercise, dietary and lifestyle interventions.
Significant improvements were seen in women who received lifestyle intervention vs. usual care, in body composition parameters of body mass index, mean difference (MD) = −0.12 kg.m−2 (95% CI [−0.22, −0.03], p = .009), body mass MD = −3.42 kg (95% CI [−4.86, −1.99], p < .00001), waist circumference MD = −1.64 cm (95% CI [−2.09, −1.19], p < .00001), waist−hip ratio MD = −0.03 (95% CI [−0.05, −0.01], p = .0002), and body fat % MD = −1.71% (95% CI [−3.10, −0.32], p = .02). Insulin did not improve, MD = −1.21 pmol/L (95% CI [−3.06, −0.63], p = .20). Lipid profile did not improve, total cholesterol MD = −0.02 mmol/L (95% CI [−0.25, 0.21], p = .89). C-reactive protein was significantly lower, MD = −0.47 mmol/L (95% CI [−0.80, −0.15], p = .004). Significant improvements were also observed in cardiorespiratory fitness with exercise alone reducing resting heart rate, MD = −1.89 beats.min−1 (95% CI [−2.90, −0.88], p = .0002), and peak VO2, MD = 4.86 ml.kg−1.min−1 (95% CI [2.83, 6.88], p < .00001). Lifestyle therapy also improved, peak VO2 MD = 5.09 ml.kg−1.min−1 (95% CI [3.13, 7.05], p < .00001).
Our analyses suggest lifestyle intervention is optimal for improving body composition and cardiorespiratory fitness in women with PCOS.

The aim of this study was to evaluate the level of physical activity and cardiorespiratory fitness in teenagers with type 1 diabetes mellitus (T1D) in comparison with healthy scholar participants. Total of 154 teenagers (T1D = 45 and CON = 109). Height, weight, cardiorespiratory fitness (VO2max), and the level of physical activity by the Bouchard’s Physical Activity Record were measured, and glycated hemoglobin (HbA1c) in T1D. The VO2max was lower in the T1D (38.38 ± 7.54) in comparison with the CON (42.44 ± 4.65; p < .05). The VO2max had correlation with the amount of time of moderate-to-vigorous physical activity (r = .63; p = .0001) and an inverse correlation with sedentary activities (r= -0.46; p = .006). In the T1D the levels of HbA1c had an inverse correlation with the amount of time of moderate-to-vigorous physical activity (r= -0.34; p = .041) and correlation with the BMI z-score (r = .43; p = .017). Only 37,8% of the participants in the T1D reached the adequate amount of daily moderate-to-vigorous intensity physical activity, in the CON 81,7% reached the WHO’s recommendation. Conclusion: T1D had less cardiorespiratory capacity then healthy controls, the teenagers of T1D with lower BMI z-score and that dedicated a greater time in moderate-to-vigorous intensity physical activity demonstrated a better glycemic control.

The beneficial effects of exercise, including reduction of cardiovascular risk, are especially important in children with type 1 diabetes (T1DM), in whom incidence of lifetime cardiovascular complications remains elevated despite good glycemic control. Being able to exercise safely is therefore a paramount concern. Dysregulated metabolism in T1DM however, causes frequent occurrence of both hypo- and hyperglycemia, the former typically associated with prolonged, moderate exercise, the latter with higher intensity, if shorter, challenges. While very few absolute contraindications to exercising exist in these children, exercise should not be started with glycemia outside the 80–250 mg/dl range. Within this glycemic range, careful adjustments in insulin administration (reduction or infusion rate via insulin pumps, or overall reduction of dosage of multiple injections) should be combined with carbohydrate ingestion before/during exercise, based on prior, individual experience with specific exercise formats. Unfamiliar exercise should always be tackled with exceeding caution, based on known responses to other exercise formats. Finally, gaining a deep understanding of other complex exercise responses, such as the modulation of inflammatory status, which is a major determinant of the cardio-protective effects of exercise, can help determine which exercise formats and which individual metabolic conditions can lead to maximally beneficial health effects.

role of physical activity in mitigating postprandial hyperglycemia, that is, enhancing glycemic control ( MacLeod, Terada, Chahal, & Boule, 2013 ). Studies have demonstrated that postprandial (postmeal) physical activity can improve glycemic control for up to 48 hr ( DiPietro, Gribok, Stevens, Hamm

). Independent of physical activity, prolonged sitting time is a risk factor for poor glycemic control, unhealthy body composition, elevated lipid levels ( Hamilton, Healy, Dunstan, Zderic, & Owen, 2008 ; Mikus et al., 2012 ; Owen, Healy, Matthews, & Dunstan, 2010 ), and Type 2 diabetes, all of which are risk
