Métodos de recuperação pós-exercício: uma revisão sistemática

A recuperação pós-exercício consiste em restaurar os sistemas do corpo a sua condição basal, proporcionando equilíbrio e prevenindo a instalação de lesões e, nesse sentido, torna-se aspecto importante de todo programa de condicionamento físico, em quaisquer níveis de desempenho, mas, sobretudo nos mais elevados. O objetivo desta revisão foi reunir informações e descrever as respostas proporcionadas por métodos recuperativos pós-exercício, como crioterapia, contraste, massagem e recuperação ativa, constituindo uma fonte de atualização do referido tema. Utilizaram-se os bancos de dados MedLine, Scielo e Lilacs, como lista de periódicos, o SportsDiscus. Foram incluídos no estudo somente ensaios clínicos randomizados controlados e não-controlados, além de artigos de revisão referentes ao tema proposto. Optou-se por procurar os termos: cryotherapy, massage, active recovery, thermotherapy, immersion e exercise, individualmente e em cruzamentos. Como achado, observou-se que alguns estudos relatam que a crioterapia é prejudicial em se tratando de recuperação pós-exercício, pois reduz o desempenho imediatamente após a aplicação da técnica. Por outro lado, estudos apontam como sendo benéfica, pois reduzem o nível de creatinaquinase após alta intensidade de esforço, evitando danos musculares. Para o contraste, embora apresente significância em se tratando de remoção de lactato sanguíneo, sua efetividade necessita ser mais bem discutida. Na massagem e na recuperação ativa, os principais vieses descritos dizem respeito à pressão exercida e à intensidade do exercício, respectivamente. Entre as técnicas, as que parecem ter efeitos semelhantes são o contraste e a recuperação ativa, no que tange à remoção de lactato e diminuição da creatinaquinase. Ressalta-se que o tempo de exposição é de fundamental importância para todos os métodos. Entretanto, diversos estudos não se propõem a identificar os reais efeitos fisiológicos promovidos pelas técnicas, utilizando-as de modo inipiente. Portanto, a inconsistência dos resultados encontrados sugere que a análise das variáveis utilizadas como método de recuperação deve ser mais bem controlada.

Capacidade funcional de hemiparéticos crônicos submetidos a um programa de fisioterapia em grupo

Este estudo tem como objetivos analisar a eficácia da fisioterapia em grupo sobre a marcha, o equilíbrio corporal e o risco de queda, e verificar se há correlação entre a capacidade funcional da marcha e o equilíbrio em indivíduos com hemiparesia crônica. Participaram do estudo 21 adultos hemiparéticos, com idade média de 58,9±10,6 anos, com seqüela de no mínimo 1 ano após acidente vascular encefálico isquêmico ou hemorrágico. Os sujeitos foram submetidos a um programa de 1 hora de fisioterapia em grupo duas vezes por semana durante seis meses. Foram avaliados por meio da escala de equilíbrio de Berg (EEB) e do teste de levantar e caminhar cronometrado TLCC (TUG, na sigla em inglês de timed up & go) antes do programa, após 13 e ao fim de 26 semanas. Os resultados mostram uma redução progressiva, embora não-significativa, no tempo de execução do TLCC e aumento progressivo, também não-significativo, do escore na EEB. Foi observada forte correlação entre as duas escalas (r=0,7, p<0,05). Assim, a terapia não foi efetiva para produzir melhora nos escores dos testes, mas contribuiu para manter a mobilidade.

Efetividade de um programa de exercícios no condicionamento físico, perfil metabólico e pressão arterial de pacientes hipertensos

Background and objective: It has been shown that aerobic exercise is useful to reduce arterial pressure, however, the effectiveness of an exercise program is still controversial and not very well analyzed among populations with low-income. The objective of the present study was to set up an individualized physical fitness program - Projeto Hipertensão - focused on hypertensive people, patients from a Health Basic Unit (HBU) and, after that, to investigate the effects of this program on physical fitness, metabolic profile and pressure levels. Methods: Sixteen hypertensive women (56 ± 3yrs) under regular pharmacological treatment underwent 4 months of a supervised aerobic and stretching exercise program (3 sessions/wk, 90 min/session, 60% of V̇O 2 max). Several physical and metabolic variables were compared before and after 4 months of training. Results: Training significantly reduced systolic arterial pressure (SAP, -6%), improved cardio-respiratory fitness (+42% of V̇O2max), flexibility (+11%) and plasma glucose content (-4%). BMI and % fat did not change. Besides modifying metabolic profile, it was found that training presented significant correlations between individual initial values of cholesterol total level (CT), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) and its responses after exercise. Conclusions: The study shows that exercise programs can be personalized for hypertensive patients from a HBU and confirms the effectiveness of exercise on AP, physical fitness, flexibility and lipid profile on hypertensive patients. The expressive reduction of AP in hypertensive subjects suggests that this exercise intervention should be emphasized on other health centers which assist low-income population.

Benefits of Multimodal Exercise Intervention for Postural Control and Frontal Cognitive Functions in Individuals with Alzheimer's Disease: A Controlled Trial

Objective To verify the effects of a systematized multimodal exercise intervention program on frontal cognitive function, postural control, and functional capacity components of individuals with Alzheimer's disease (AD).DesignNonrandomized controlled trial with pre- and posttraining tests in a training group and a control group.SettingKinesiotherapy program for seniors with AD, SAo Paulo State University.ParticipantsConvenience sample of older adults with AD (n=30) were assigned to a training (n=14; aged 78.67.1) and a control (n=16; aged 77.06.3) group.InterventionThe intervention program was structured with the aim of simultaneously promoting better balance and frontal cognitive capacity. The participants attended a 1-hour session three times a week for 16weeks, whereas the control group did not participate in any activity during the same period.MeasurementsFrontal cognitive function was evaluated using the Montreal Cognitive Assessment, the Clock Drawing Test, the Frontal Assessment Battery, and the Symbol Search Subtest. Postural control (center of pressure area) was analyzed under four dual-task conditions. Functional capacity components were analyzed using the Timed Up and Go Test, the 30-second sit-to-stand test, the sit-and-reach test, and the Berg Functional Balance Scale.ResultsIntervention group participants showed a significant increase in frontal cognitive function (P<.001, partial (2)=0.838), with less body sway (P=.04, partial (2)=0.04) during the dual tasks, and greater functional capacity (P=.001, partial (2)=0.676) after the 16-week period.ConclusionIntervention participants performed better on dual-task activities and had better postural balance and greater functional capacity than controls.

Long duration exercise program in individuals with parkinson´s disease: effects on functional capacity

The aim of this study was to investigate the effects of long duration exercise program on physical fitness components of functional capacity in individuals with Parkinson disease (PD) and to evaluate ongoing effects of exercise after 8 to 10-week follow-up without exercise. Twenty-four individuals with PD were randomly assigned to two groups: generalized exercise program and stretching exercise program (control group). The generalized exercise program provided training in physical fitness components of functional capacity. The stretching exercise program was characterized by low intensity and volume, mainly with static exercises. Both groups were evaluated before (BI) and after the 4-month (AI) exercise program. In addition, the individuals of generalized exercise program were also evaluated after 8-month exercise program and after 8 to 10- week follow-up without exercise. The generalized exercise program improved flexibility (BI - 38.50±12.42 cm; AI - 44.00±12.74 cm) and agility (BI - 30.59±7.54 s; AI - 28.56±8.20 s) while the stretching exercise program worsened coordination (BI - 23.27±6.58 s; AI - 28.06±7.37 s) and aerobic resistance (BI- 13.64±3.76 min; AI - 17.27±5.15 min) and improved balance (BI - 44.00±7.79 pts; AI - 46.57±6.53 pts). Lower-limb strength and UPDRS-motor scale scores were better at 8 months (14.75±2.92 rep and 26.25±13.97 pts, respectively) compared to baseline (13.13±2.59 rep and 31.63±12.82 pts, respectively) and 4 months (13.50±1.93 rep and 30.38±14.52 pts, respectively) for generalized exercise program. However, the benefits of 8 months of exercise were lost after 8 to 10-week follow-up without exercise (lower-limb strength - 12.43±3.15 rep and UPDRS-motor scale - 32.57±14.05 pts). In conclusion, generalized exercise program improved the functional capacity in individuals with PD, differently of stretching exercise program. In addition, a long duration exercise program promoted benefits for functional capacity and disease progression in individuals with PD. However, benefits were lost after a short period without exercise.

Improvements of nutrition behavior fitness and body fatness with a short-term after school intervention program

The prevalence of childhood obesity has been increasing worldwide and lifestyle changes are the most important strategies in managing this prevalence. This study aimed to describe the intervention effects of nutrition and physical activities offered as an after school short-term on outcomes of healthy nutrition practices, fitness and lowering fatness. This quasi-experimental study was conducted with a convenience sample of 59 caucasian children, aged 7.7 ± 1.4 years old (52.5% girls) registered on a private school of a middle-size town located in Sao Paulo State, Brazil. The school-based 12-week intervention consisted of 2 weekly 60 minutes section, during 3 months, including a nutritional education and a physical activity curriculum. Anthropometric data was measured for all children at baseline and after 12 weeks. All parents were contacted and requested to complete questionnaire about child’s eating behavior at baseline and after the 12-week program. After the intervention, children showed an increasing in the intake of fruits (64.3%), vegetables (61.9%), and water (52.0%). Overall, 83.3% of the children changed eating behavior according to the questionnaire responded by the parents. Waist circumference was significantly lower and abdominal strength improved after participating in the intervention program. Mean height and weight were significantly higher in boys and girls after a 12-week intervention. Although mean values of BMI remained the same after the intervention it was observed a decreasing in the prevalence of obesity among the children. Thus our study showed that a school-based intervention program focused on nutritional education and physical activity program promoted waist circumference reduction and decreased obesity without affecting the height growth along with improved fitness and healthy eating behavior. This intervention program would be feasible and replicable in others schools around the country.
