Acute Effects of High-Intensity Interval Training on Diabetes Mellitus: A Systematic Review.

This study evaluated the scientific evidence on the acute effects of high-intensity interval training (HIIT) on biochemical, cardiovascular, and metabolic parameters in patients with diabetes mellitus. The research took place using two databases (PubMed and Google Scholar) with eligible studies conducted between 2010 and 2020, using the following keywords: (1) high-intensity training/exercise; (2) interval training/exercise; (3) HIIT/exercise; AND "diabetes". Data extraction was then performed on the eligible studies through content analysis using the categories: author and year of publication; sample characteristics; methods and data collected; intervention protocol; and results found. Methodological quality was assessed using the PEDro scale. Fourteen studies were included, evaluating 168 people with diabetes (122/46 type 2/1) and 42 normoglycemic individuals, which evaluated markers such as capillary and fasting blood glucose, 24-h blood glucose profile, postprandial blood glucose, incidence, and prevalence of hyperglycemia, vascular function and pressure response and control of inflammatory markers. Physical exercise was found to have several acute beneficial effects on the health of the diabetic population, such as reduced capillary and postprandial blood glucose, blood glucose profile, and blood pressure. Moreover, HIIT seems to be a safe and effective alternative in glycemic control and associated factors, superior to continuous moderate-intensity training.

HIIE Protocols Promote Better Acute Effects on Blood Glucose and Pressure Control in People with Type 2 Diabetes than Continuous Exercise.

This study compared the acute effects of a session of different high-intensity interval exercise (HIIE) protocols and a session of moderate-intensity continuous exercise (MICE) on blood glucose, blood pressure (BP), and heart rate (HR) in people with Type 2 Diabetes Mellitus (DM2). The trial included 44 participants (age: 55.91 ± 1.25 years; BMI: 28.95 ± 0.67 kg/m2; Hb1Ac: 9.1 ± 2.3%; 76 mmol/mol) randomized into three exercise protocols based on the velocity at which maximum oxygen consumption was obtained (vVO2 max): long HIIE (2 min at 100% vV̇o2peak + 2 min of passive rest); short HIIE (30 s at 100% vV̇o2peak + 30 s of passive rest); or MICE (14 min at 70% vV̇o2peak) on a treadmill. Capillary blood glucose, BP, and HR measurements were taken at rest, during peak exercise, immediately after the end of exercise, and 10 min after exercise. Long and short HIIE protocols reduced capillary blood glucose by 32.14 mg/dL and 31.40 mg/dL, respectively, and reduced systolic BP by 12.43 mmHg and 8.73 mmHg, respectively. No significant changes were observed for MICE. HIIE was found to promote more acute effects than MICE on glycemia and BP in people with DM2.

Non-immersive 3D virtual stimulus alter the time production task performance and increase the EEG theta power in dorsolateral prefrontal cortex.

AIM: The study investigated the cortical activity changes and time production task performance induced by changes in motion speed of a non-immersive 3D virtual stimulus. MATERIAL AND METHODS: Twenty-one individuals were participated in the crossover study with the visual-time reproduction task under three-speed conditions: original, slow and fast virtual stimulus. In addition, the electroencephalographic analysis of the theta band power in the dorsolateral prefrontal cortex was done simultaneously with time production task execution. RESULTS: The results demonstrated that in the slow speed condition, there is an increase in the error in the time production task after virtual reality (p < 0.05). There is also increased EEG theta power in the right dorsolateral prefrontal cortex in all speed conditions (p < 0.05). CONCLUSIONS: We propose that the modulations of speed of virtual stimulus may underlie the accumulation of temporal pulses, which could be responsible for changes in the performance of the production task of the time intervals and a substantial increase in right dorsolateral prefrontal cortex activity related to attention and memory, acting in cognitive domains of supraseconds.

Dental alterations on panoramic radiographs of patients with osteogenesis imperfecta in relation to clinical diagnosis, severity, and bisphosphonate regimen aspects: a STROBE-compliant case-control study.

OBJECTIVE: This study aimed to assess the prevalence of dental findings on panoramic radiographs (PRs) of patients with osteogenesis imperfecta (OI) and correlate these results with epidemiologic and medical data. STUDY DESIGN: A case-control study was conducted with 24 patients with OI and 48 sex- and age-matched controls. Demographic, clinical, and bisphosphonate regimen-related data were recorded. The outcome variables were the presence or absence of dental alterations in PRs. Mann-Whitney U test, Pearson's χ2 test, and multinomial logistic regression analysis (95% confidence interval) were used (significance level of 5%). RESULTS: OI type 4 demonstrated a high prevalence (62.5%), followed by type 1 (37.5%). With regard to prevalence associated with severity, the moderate form was the most prevalent (P = .028). The mean time of intravenous pamidronate regimen was 6.6 ± 4.4 years. Dentinogenesis imperfecta was observed in 75% of patients with OI, and this group showed a high prevalence of dental abnormalities in comparison with controls (P < .05). Bisphosphonate therapy was associated with ectopic teeth (P = .007) and tooth impaction (P = .033). Pulp obliteration was significant with bisphosphonate treatment over a period of 7 years (P = .026). CONCLUSIONS: This study found a significant prevalence of dental alterations in patients with OI, and certain alterations were associated with bisphosphonate therapy, indicating its influence on the dentin-related physiopathology.

Physical Fitness and Anthropometric Measures of Young Brazilian Judo and Wrestling Athletes and Its Relations to Cardiorespiratory Fitness.

This study aimed to compare the anthropometric profile and physical fitness of young judo and wrestling athletes. Twenty-four young athletes (judo (n = 13) and wrestling (n = 11)) participated in this study. The first visit involved anthropometric and flexibility evaluation, abdominal endurance test, upper limbs resistance and cardiorespiratory test. After 48 h, horizontal jump test (HJT), vertical jump test (VJT), medicine ball throw test (MBT), chin-up test (CUT), chin-up isometric test (CUIT) and the anaerobic resistance test were performed. Judo athletes presented greater values for body mass (p = 0.020), height (p = 0.010), and body mass index (p = 0.026) than wrestlers. Judo athletes also performed better for abdominal endurance (p = 0.044), upper limb resistance tests (p < 0.001), VJT (p = 0.022) and MBT (p = 0.023) than wrestling athletes. These results suggest that young judo athletes presented a higher performance in abdominal endurance, upper limbs resistance, HJT, VJT and MBT than wrestling athletes, suggesting that strength and conditioning are related to modality specificity.

Movement automatization: motor interactions and electroencephalogram application / Automatização do movimento: interações motoras e aplicação do eletroencefalograma

The specificities of the motor system lead people to present skills to perform some movements in an automatic way after learning. Acquiring the automaticity of the movements is usually associated with reducing the demands of attention control. Thus, automatization represents a reduction in interference that undermines performance in dual task conditions. It was carried out a search on the databases of Pubmed, Scopus, SciELO e Lilacs, to understand the physiology of automaticity and analyze the use of electroencephalogram as a means of research in automatization. In this context, the study aims to verify the employment of the electroencephalogram as a resource in the analysis of the motor skills involved in the movement automatization.

Fatores associados à subestimação materna do peso da criança: um estudo de base populacional / Factors associated with maternal underestimation of child's weight: a population-based study

Objetivo Investigar os fatores associados à subestimação materna do peso de crianças menores de cinco anos de Goiânia, Goiás. Métodos Estudo transversal, de base populacional, domiciliar, com 673 crianças menores de cinco anos de idade. A percepção materna do peso da criança foi obtida pela pergunta: "Atualmente, o que a senhora (mãe) acha do peso do seu filho?", e o estado nutricional da criança foi avaliado pelo índice de massa corporal por idade. Regressão múltipla de Poisson foi realizada a um nível de significância de 5%. Para a análise de concordância, foi utilizado o teste Kappa. Resultados Das crianças estudadas, 1,6% estavam magras, 87,7% eutróficas e 10,7% com excesso de peso. A maioria das mães (66,0%) identificou corretamente o peso de seus filhos; 5,2% superestimaram, e 28,8% subestimaram. Mães de crianças com excesso de peso, idade superior a 24 meses, apresentaram maior prevalência de subestimação, enquanto as mães com excesso de peso e maior escolaridade apresentaram menor subestimação do peso das crianças. A concordância entre a opinião materna sobre o peso da criança e o real estado nutricional da criança foi de 0,12 (p<0,001). CONCLUSÃO Existe uma distorção na percepção materna do peso de crianças menores de cinco anos. A subestimação materna do peso da criança apresentou associação direta com idade e estado nutricional da criança e associação inversa com escolaridade e estado nutricional materno. Sugere-se atenção no atendimento a essas mães com o objetivo de evitar o ganho de peso excessivo nessa idade e prejuízos na saúde da criança. .

Objective To investigate the factors associated with maternal underestimation of weight status of children under five years in Goiânia, Goiás, Brazil. Methods A population-based cross-sectional study involving 673 children under five years of age was carried out. Maternal perception of child's weight was assessed by the question: "What do you think about your child's current weight?". The child's nutritional status was determined in terms of body mass index-for age. Poisson regression was used at 5% significance level. Concordance analysis was performed using the Kappa test. Results Among the children studied, 1.6 % were lean, 87.7% eutrophic, and 10.7% overweight. Most mothers (66.0%) correctly classified the weight of their children, 5.2% overestimated it, and 28.8% underestimated it. Mothers of overweight children and those whose children were older than 24 months had a higher prevalence of underestimation of weight, whereas the overweight mothers and those with higher education level had a lower prevalence of underestimation of weight of their children. The correlation between maternal perception of the chil's weight and the actual child's nutritional status was 0.12 (p<0.001). Conclusion Maternal misperception of weight of children under five years was observed. Maternal underestimation of their child's weight was directly associated with age and nutritional status of the child, and it was inversely associated with maternal education level and nutritional status. More attention should be paid to these mothers in order to prevent excessive weight gain at this age and further harm to children's health. .
