Effects of aquatic high intensity interval training on parameters of functional autonomy, mental health, and oxidative dysfunction in elderly subjects with type 2 diabetes.

The present study investigated the effects of aquatic exercise on parameters of functional autonomy, mental health, and oxidative dysfunction in elderly patients with DM2. A total of 130 elderly were included in the longitudinal clinical study and were attributed to the non-diabetic group (n = 27) and diabetes the group (n = 22). Both groups participated in 24 sessions of Hydro-HIIT, 48 h before and after Hydro-HIIT, the GDLAM index, depression, and anxiety scores and markers of oxidative dysfunction were quantified. After intervention, GI decreased in both groups (non-diabetes group = -24%; diabetes group = -22%) (p < 0.05), markers of depression (-46%), anxiety (-60%), DCFH-DA (-55%), SOD (+59%), TNF-α (-37%) and IL-1 (-48%) in diabetes group (p < 0.05). The intervention with Hydro-HIIT improves aspects related to functional autonomy, mental health, and exerts consequently, a modulating effect on oxidative stress and inflammatory response in elderly people diagnosed with DM2.

Injuries in CrossFit practioner: a cross-sectional study

Abstract Aim: The present study aimed to investigate epidemiological parameters associated with the onset of injuries in CrossFit practitioners. Methods: Cross-sectional study, with fifty-two subjects (28 ± 7 years,70 ±13 kg), regular practitioners of CrossFit, of intermediate level. The Rombaldi questionnaire was applied, related to the occurrence of injuries during physical activity. The Shapiro-Wilk normality test, Pearson's chi-square, and Fisher's exact test were used, using p < 0.05. Results: Our findings show that the prevalence of injury in cross-fitters is 38%, having an incidence rate of 3.7 per 1000 h of training. The most recurrent injury was stretching (41%). The most affected regions were the shoulder and lumbar (34%). The exercise model with the highest association with injury development was Olympic weightlifting (p = 0.004). Conclusion: The CrossFit practice showed a moderate prevalence of injuries, stretching the main type. The most affected regions were the shoulders and the lumbar. In relation to the most dangerous exercise model for the appearance of injuries, the Olympic weightlifting exercises stand out.

Effect of aquatic exercise on mental health, functional autonomy, and oxidative damages in diabetes elderly individuals.

This study investigated the effect of aquatic exercise on mental health, functional autonomy, and oxidative dysfunction in elderly with DM2. A total of 104 elderly were included in the longitudinal clinical study and were attributed to the diabetes group (n = 30) and the non-diabetic group (n = 29). Both groups were involved in the aquatic exercise (nine exercises; 3 sets x 1-minute duration each; linear intensity and frequency measured twice a week) for 12 weeks. The assessments of mental health, functional autonomy, and oxidative dysfunction were done. All results were evaluated at baseline and 12 weeks later. The values of the following variable scores decreased in the DM2 group after participation in the aquatic exercise: depression (-56 ± 2 scores; 57%), anxiety (-8.2 ± 2 scores; 41%), stress (-3.1 ± 0.3 scores; 32%), and sleep (-3. 7 ± 1.3 points; 51%); an improvement in Berg scores was observed (+53.1 ± 2 points; 8%), Tug tests (-6.1 ± 0.7 points; 25%), carbonyl groups (-0.048 ± 0.01 nnmol/mg/protein; 49%), and total thiol (+0.33 ± 0.08 nnmol/mg/protein; 83%). We have concluded that a linear intensity aquatic exercise program improves mental health, functional autonomy, and oxidative dysfunction in elderly with DM2.

Qualidade de vida e fatores associados em trabalhadores de uma Universidade do Sul de Santa Catarina / Quality of life and factors associated of University employees from southern Santa Catarina State

Resumo Introdução A qualidade de vida de trabalhadores interfere no desenvolvimento e na produtividade do trabalho e pode ser influenciada por diversos fatores sociodemográficos e laborais. Objetivo Avaliar os fatores associados à qualidade de vida de funcionários de uma Universidade. Método Estudo transversal realizado com 214 trabalhadores de ambos os sexos pertencentes aos dezenove setores da Universidade. Para avaliar a qualidade de vida, utilizou-se o WHOQOL-Bref. A associação de cada domínio da qualidade de vida com as variáveis de exposição foi avaliada através do teste t para amostras independentes ou análise de variância, seguida do teste de Bonferroni. Resultados As médias dos domínios de qualidade de vida foram: 74,64 (±13,52) para o físico, 71,12 (±12,85) para o psicológico, 76,94 (±13,98) para o de relações sociais e 61,94 (±16,30) para o ambiente. Os homens apresentaram maiores médias para os domínios físico, psicológico e de relações sociais. Trabalhadores com idade maior do que 38 anos apresentaram maiores médias no domínio psicológico. Já no domínio relações sociais, as maiores médias foram observadas entre os indivíduos de 18 a 27 anos. Naqueles indivíduos que dormiam menos de 8 horas por dia, as médias do domínio físico foram menores. Conclusão Fazem-se necessárias ações de prevenção e promoção da qualidade de vida no trabalho, especialmente direcionadas aos funcionários que apresentaram as menores médias nos domínios de qualidade de vida.

Abstract Background Life quality of workers influences on development and productivity of work and it can be influenced by several sociodemographic and labor factors. Objective To evaluate the associated factors with quality of life of University workers from southern Santa Catarina State. Method A cross-sectional study with 214 workers was carried out. WHOQOL-Bref was used to evaluate the quality of life. The quality of life domains were associated to exposure variables. The statistical analysis T-test for independent samples and analysis of variance, followed by the Bonferroni test were used. Results The mean of quality of life domains were: 74.64 (±13.52) for the physical domain, 71.12 (±12.85) for the psychological, 76.94 (±13.98) for social relations domain and 61.94 (±16.30) for the environment domain. Males presented higher mean for the physical, psychological and social relations domains. Workers older than 38 years of age presented higher means in the psychological domain. In the social relations domain, the highest mean was observed among individuals aged 18 to 27 years. In those individuals who slept less than 8 hours a day, the mean of the physical domain were smaller. Conclusion It is necessary the development of actions to prevent and promote life quality at work focusing on employees who had the lowest averages of the domains of that.

Swimming training improves mental health parameters, cognition and motor coordination in children with Attention Deficit Hyperactivity Disorder.

The aim of this study was to verify the effects of swimming-learning program of mental health parameters, cognition and motor coordination in students with Attention Deficit Hyperactivity Disorder (ADHD). Thirty-three children of both sexes between 11 and 14 years were randomized into trained group (n = 18) and untrained group (n = 15). The training was performed for 8 weeks. Then, before and after 48 h of training period of both groups were submitted to find the mental health, cognition, motor coordination test, and physical fitness. Our results demonstrate that the aquatic exercise program significantly improved the depression parameters (p = 0.048), stress (p = 0.039), cognitive flexibility (p = 0.042) and selective attention (p = 0.047). In relation to motor coordination and physical fitness, the results showed significant improvements in the coordination of lower limbs laterality (p = 0.05), flexibility (p = 0.049), and abdominal resistance (p = 0.037). Taken together, the results suggest that swimming-learning program significantly improved the mental health, cognition, and motor coordination in children with ADHD.

Effects of different frequencies of physical training on electron transport chain and oxidative damage in healthy mice

The present study investigated the effect of different frequencies (three and five times a week) on electron transport chain and oxidative stress after 8 weeks of run training. Methods: Eighteen male mice (CF1, 30-35g) were distributed into the following groups (n=6): untrained (UT); trained three-time per week (T3) and trained five- time per week (T5). All training sessions were at the same intensity and duration (45min/day) in a treadmill for small animals. Forty-eight hours after the last training session, the animals were killed by decapitation and quadriceps (red portion) was removed and stored at -70ºC. Succinate dehydrogenase (SDH), complexes I, II, II-III, IV and hydroperoxides were measured. Results: Training sessions for five times per week were more effective in increasing the mitochondrial respiratory chain enzyme activities (SDH, complexes I, II, II-III, IV) as well as in decreasing the formation hydroperoxides than sessions performed for three times training per week (p<0.05). Conclusion: Our findings clearly showed that a higher the frequency of training session promotes a greater activity of the electron transport chain and consequently reduces the oxidative stress in healthy animals.(AU)
