Effect of Resistive Exercise on Muscle Damage in Water and on Land

Pantoja, PD, Alberton, CL, Pilla, C, Vendrusculo, AP, and Kruel, LFM. Effect of resistive exercise on muscle damage in water and on land. J Strength Cond Res 23(3): 1051-1054, 2009-The purpose of this study was to compare the effects of resistance exercise in water and on land on blood levels of creatine kinase (CK), a known indirect marker of muscle damage. Nine men (age: 23 ± 1.58 years; weight: 79.37 ± 11.15 kg; height: 176.33 ± 4.09 cm), who had not practiced resistance training for at least 6 months before this experiment, performed 3 sets of maximum elbow flexion and extension exercises in water and on land, separated by 2-minute periods of rest. A 10-repetition maximum test was used to load control on land with free weights, and in water the exercise was performed at maximum velocity with aquatic resistance equipment. The duration of the exercise in water was the same as that performed on land, to reproduce the same metabolic route. Plasma CK activity was determined using a commercially available kit (Labtest Enzymatic-UV) before exercise, after exercise, and at 24 and 48 hours after exercise. Significant increases in CK were found at 48 hours postexercise on land (preexercise land: 160.75 ± 96.05 U·L−1; 48 hours: 326.87 ± 240.84 U·L−1), and significant differences were found between land and water (preexercise water: 147.75 ± 46.48 U·L−1; 48 hours: 121.75 ± 30.86 U·L−1) for this measure. However, no significant differences were found in water. In conclusion, the water environment influenced the absence of significant muscle damage. This type of exercise protocol may be appropriate for situations in which limited muscle tissue damage is desired.

Efeito da hidrocinesioterapia na força muscular e na flexibilidade em idosas sedentárias

INTRODUCAO: O envelhecimento populacional e um desafio para a saude, e a cada ano ha um aumento dessa populacao. Entre as alteracoes anatomofisiologicas caracteristicas deste processo, as do sistema muscular sao relevantes, ocorrendo diminuicao da forca muscular e da flexibilidade durante esta etapa. OBJETIVO: Analisar o efeito de um programa de hidrocinesioterapia no comportamento da forca muscular e da flexibilidade em idosas sedentarias. METODOLOGIA: Participaram 23 idosas sedentarias, com independencia funcional e que nao realizaram cirurgia nos ultimos tres meses. O programa ocorreu durante oito semanas, com tres sessoes semanais de 55 minutos. As variaveis foram avaliadas em tres momentos (Pre, Pos 1, Pos 2). Para avaliacao de forca foram utilizados testes musculares manuais, e para flexibilidade foi aplicado o teste de sentar e alcancar. Para comparar as medias da forca, foi aplicado o teste nao parametrico de Friedman e um teste de comparacoes multiplas a ele associado. O teste de Page foi aplicado para verificar se as medias dos momentos estavam em ordem crescente. RESULTADOS: Para a flexibilidade, as medias foram respectivamente 11,01 cm, 5,57 cm e 2,88 cm, o que foi significativo. Ja nos dados de forca, embora nao se tenha obtido diferenca estatisticamente significativa, os resultados obtiveram uma ordem crescente: biceps braquial - 4,49/5,00; abdominais - 2,22/4,48; isquiotibiais - 4,35/5,00. CONCLUSAO: O programa de hidrocinesioterapia proporcionou melhora da forca muscular e da flexibilidade das idosas, confirmando que um programa de exercicios adequado associado a acao das propriedades fisicas da agua foi ideal para alcancar o objetivo proposto.

Oficina sobre orientações pedagógicas no ensino superior: ação do programa pró-saúde

Objective: To analyze the strengths and challenges in teaching on a higher education institution according to the vectors proposed by the Ministry of Health Pro-Health Project. Materials and Methods: We conducted a qualitative research, in which the analysis of content in focal groups was used. In 2009, a workshop was organized by the Pro-Health’s internal commission to discuss the potentialities and challenges according to the main concerns regarding the program. Results: Among the potentialities discussed, it was highlighted the activities structure, internships and curricular practices from the institution integrated to the reality and needs of the population. However, the interdisciplinary approach has been pointed as the biggest challenge to be implemented in the health field. None of the evidence reached the stage III, which means that none were totally achieved according to the professionals. Conclusion: There is a need for constant discussion among teachers so that they can achieve satisfactory results, however, we suggest to work with a smaller number of participants.
