Effects of 16 weeks of a physical exercise program on blood markers, functional autonomy and level of depression in elderly and old adults.

O objetivo foi analisar os efeitos de um programa de exerc?cio f?sico sobre marcadores sangu?neos, autonomia funcional e n?vel de depress?o. Um total de 112 sujeitos com doen?as metab?licas controladas por hipocolesterolemia e hipoglicemiantes distribu?dos em dois grupos participaram do estudo; grupo composto por 54 membros com idade m?dia de 62,11 anos e grupo controle (GC) com 58 indiv?duos com idade m?dia de 63,03 anos. Foi observado que a ur?ia, creatina e as vari?veis pot?ssio n?o apresentaram diferen?a interessante entre os dois momentos do estudo, enquanto TGP e s?dio obtiveram redu??es nos valores m?dios de 2,46 mg / dl e 10 mg / dl com grande efeito de ?p2 0,153, ?p2 0,43 e signific?ncia p <0,047 e p <0,039 ao comparar os dois momentos entre os grupos exerc?cio / controle. A qualidade da for?a entre os momentos pr? e p?s entre os grupos exerc?cio / controle mostrou um aumento de 2,53 kgf de pequeno efeito de ?p2,23 para o grupo exerc?cio, enquanto o controle reduziu. Tamb?m houve diferen?as entre o pr? e o p?s-treinamento nos indicadores de autonomia funcional dos grupos GC. O GE reduziu os n?veis de depress?o em rela??o ao GC. Concluiu-se que o treinamento f?sico realizado por 16 semanas foi eficaz na redu??o dos n?veis de s?dio, a vari?vel TGP, aumento dos n?veis de for?a dos membros superiores, al?m de favorecer a melhora da capacidade funcional e reduzir os n?veis de depress?o.The objective was to analyze the effects of a physical exercise program on blood markers, functional autonomy and level of depression. A total of 112 subjects with metabolic diseases controlled by hypocholesterolemia and hypoglycemics distributed in two groups participated in the study; group composed of 54 members with mean age of 62.11 years and control group (CG) with 58 individuals with a mean age of 63.03 years. It was observed that urea, creatine and potassium variables did not present an interesting difference between the two moments of the study, while TGP and sodium obtained reductions in mean values of 2.46 mg / dl and 10 mg / dl with a great effect of ?p2 0.153, ?p2 0.43 and significance p <0.047 and p <0.039 when comparing the two moments between the exercise / control groups. The quality of the force between the pre and post moments between the exercise / control groups showed an increase of 2.53 kgf of small effect of ?p2,23 for the exercise group, while the control reduced. There were also differences between pre and post-training in the functional autonomy indicators of the CG groups. The GE reduced the levels of depression compared to the CG. It was concluded that physical training performed for 16 weeks was effective in reducing sodium levels, the TGP variable, increased strength levels of the upper limbs, as well as improving functional capacity and reducing depression levels

O Brasil est? entre os pa?ses que contribuir?o para essa proje??o, com um aumento significativo at? 2030. O objetivo foi analisar os efeitos de um programa de exerc?cio f?sico sobre marcadores sangu?neos e qualidade do sono em idosos. Um total de 118 idosos com doen?as metab?licas controladas por medica??es hipocolesterol?micas e hipoglicemiantes participaram do estudo. Os participantes foram divididos em dois grupos, um grupo exerc?cio (GE) composto por 58 indiv?duos com idade m?dia de 62 anos e grupo controle (GC) de 60 indiv?duos com m?dia de idade de 63 anos. Os n?veis de glicose no sangue mostraram uma redu??o m?dia de cerca de 23 mg / dl. O escore do PSQI mostrou uma redu??o significativa de cerca de 3 pontos (p <0,001, ?p2 = 0,78) na compara??o do GE com o GC. Pode-se concluir que o programa combinado de exerc?cio f?sico, realizado por 12 semanas, com frequ?ncia de tr?s vezes por semana, durante 60 min, foi eficaz na melhora da qualidade do sono dos idosos. Palavras-chave: Exerc?cio F?sico, Elderly, Glicose, Qualidade do Sono.Population aging in the world has been high in developing countries in the last decades. Brazil is among those countries that will contribute to this projection, with a significant increase until 2030. The objective was to analyze the effects of a physical exercise program on blood markers and sleep quality in the elderly. A total of 118 elderly people with metabolic diseases controlled by hypocholesterolemic and hypoglycemic medications participated in the study. The participants were divided into two groups, an exercise group (EG) composed of 58 individuals with a mean age of 62 years and control group (CG) of 60 individuals with a mean age of 63 years. Blood glucose levels showed a mean reduction of about 23 mg/dl. The PSQI score showed a significant reduction of about 3 points (p < 0.001, ?p2=0.78) on comparing the EG with the CG. It can be concluded that the physical exercise combined program performed for 12 weeks at a frequency of three times a week for 60 min, was effective in improving the sleep quality of the elderly.

Evaluation of the special judo fitness test, heart rate and lactate before and after training with restricted vision.

Objetivo: Avaliar o Special jud? Fitness Test (SJFT), a frequ?ncia card?aca (FC) e os n?veis de lactato (Lac) no desempenho dos atletas com e sem restri??o da vis?o antes e ap?s do treinamento restritivo da vis?o. Metodologia: Atrav?s do SJFT as vari?veis do ?ndice do teste, assim como verifica??o do desempenho dos atletas no treino e pos treino observando a freq??ncia card?aca atrav?s de um monitor card?aco RS 400- Polar e o n?vel de lactato, em dois momentos imediatamente ap?s o teste e 15` minutos p?s-teste com o judoca em posi??o passiva (repouso). A amostra foi composta por 30 atletas de Jud? com faixa et?ria de idade entre 18 a 30 anos, com experi?ncia m?nima de um ano de pratica da modalidade, todos do sexo masculino, onde a escolha se deu pelo fato de serem as categorias de idade mais concorrida atualmente no cen?rio competitivo.

Conclusion: Athletes with restricted eyesight tend to have an important adjustment that indicated the best in the restricted test of this sense

Does Croton argyrophyllus extract has an effect on muscle damage and lipid peroxidation in rats submitted to high intensity strength exercise?

Many species of the genus Croton have been used for anti-inflammatory, antiproliferative, antidiabetic, and antitumor purposes. The objective was to evaluate the e ect of a hydroethanolic extract (HEE) from the inner bark of Croton argyrophyllus (Euphorbiaceae) on muscle damage and oxidative stress in rats after high intensity exercise. The animals were divided into four groups: (i) the sedentary group (SV; n = 7), (ii) the exercise vehicle group (EV, n = 7), (iii) the sedentary group HEE (SHG; n = 7) composed of sedentary animals and treated with the hydroethanolic extract of C. argyrophyllus (200 mg/kg, v.o.), and (iv) the HEE exercise group (HEE; n = 7) composed of animals submitted to resistance exercise (RE) and treated with the hydroethanolic extract of C. argyrophyllus (200 mg/kg, v.o.). In the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) test, the HEE showed lower values of inhibition potential (IP%) at 39.79% compared to gallic acid, 87.61%, and lipoperoxidation inhibition at 27.4% (100 ?g/mL) or 28.6% (200 ?g/mL) (p < 0.001). There was inhibition in free radicals in vivo. The HEE of C. argyrophyllus partially reduced the biomarkers of oxidative stress in muscle tissue and muscular damage (creatine kinase (CK) and Lactate Dehydrogenase (LDH)) (p < 0.05) in rats, and in this sense it can be an aid to the recovery process after exhaustive e orts
