ABSTRACT
Introducción. En la práctica deportiva, la fatiga muscular es un factor de riesgo para lesión muscular, constituyéndose en un problema que aparece cuando la carga mecánica a la cual se somete un músculo o grupo muscular es superior a la resistencia de este. Objetivo. Describir las intervenciones con crioterapia en Fatiga Muscular post esfuerzo, en individuos que realizan práctica deportiva, a través de una Revisión Sistemática. Método. Se realizó la búsqueda en bases de datos PUBMED/MEDLINE, EMBASE, LILACS, SCIELO, SCIENCE DIRECT, Registro Cochrane Central de Ensayos Controlados con la estrategia de búsqueda: Sports Medicine, Cryotherapy, Muscle Fatigue, Recovery of Function, Physical Exertion, Muscle Damage. La identificación y detección de las referencias fueron exportadas al gestor de referencias MENDELEY. La evaluación del Riesgo de Sesgo se realizó con el uso del software Review Manager y la calidad metodológica con lo reportado por la Base de Datos PEDro. Resultados. Se evaluaron 19 ensayos clínicos aleatorizados en los cuales se evidencia que la crioterapia reporta cambios en la fatiga muscular desde la disminución del dolor y biomarcadores. La inmersión en agua fría fue la modalidad más efectiva para acelerar la cinética de recuperación 72 horas después del ejercicio; demostró menor dolor y mayores niveles de recuperación, percibidos a lo largo de 24 a 48 horas después del ejercicio. Conclusión. De la totalidad de modalidades de crioterapia, la inmersión en agua fría es la que reporta mejores resultados en el proceso de recuperación de la fatiga muscular.
Introduction. In sports practice, muscle fatigue is a risk factor for muscle injury becoming a problem that appears when the mechanical load to which a muscle or muscle group is subjected is greater than its resistance. Objective. Describe post-effort Muscular Fatigue in active Men and Women who perform sports practice against interventions with cryotherapy, through a Systematic Review. Method. PUBMED / MEDLINE, EMBASE, LILACS, SCIELO, SCIENCE DIRECT, Central Cochrane Registry of Controlled Trials with the search strategy were searched: Sports Medicine, Cryotherapy, Muscle Fatigue, Recovery of Function, Physical Exertion, Muscle Damage The identification and detection of references were exported to the MENDELEY reference manager. The Bias Risk assessment was performed with the use of Review Manager software and methodological quality as reported by the PEDro Database. Results. 19 randomized clinical trials were evaluated in which it is evident that cryotherapy reports changes in muscle fatigue since the decrease in pain, and biomarkers. Cold water immersion was the most effective modality to accelerate recovery kinetics 72 hours after exercise; showed less pain and higher levels of recovery perceived over 24 to 48 hours after exercise. Conclusion. Of all the cryotherapy modalities, the immersion in cold water is the one that reports the best results in the process of recovery of muscular fatigue.
Introdução. Na prática esportiva, a fadiga muscular é um fator de risco para a lesão muscular, tornando- se um problema que ocorre quando a carga mecânica à qual um músculo ou grupo muscular é submetido é superior à resistência do músculo. Objetivo. Descrever as intervenções com crioterapia na fadiga muscular pós-esforço, em indivíduos que realizam prática esportiva, por meio de uma revisão sistemática. Método. Foi realizada uma busca nas bases de dados PUBMED/MEDLINE, EMBASE, LILACS, SCIELO, SCIENCE DIRECT, Registro Central Cochrane de Ensaios Controlados com a estratégia de busca: Medicina Esportiva, Crioterapia, Fadiga Muscular, Recuperação da Função, Esforço Físico, Dano Muscular. A identificação e detecção das referências foram exportadas para o gerenciador de referência do MENDELEY. A avaliação do risco de viés foi realizada com o uso do software Review Manager de revisão e qualidade metodológica com a relatada pelo banco de dados PEDro. Resultados. Dezenove ensaios clínicos randomizados foram avaliados nos quais se evidencia que a crioterapia relata alterações na fadiga muscular desde a diminuição da dor e dos biomarcadores. A imersão em água fria foi a modalidade mais eficaz para acelerar a cinética de recuperação 72 horas após o exercício; demonstrou menos dor e níveis mais altos de recuperação, percebidos entre 24 e 48 horas após o exercício. Conclusão. De todas as modalidades de crioterapia, a imersão em água fria é a que proporciona os melhores resultados no processo de recuperação da fadiga muscular.

Objective To assess the series of special anti-fatigue foods including JuntiⅠ, JuntiⅡ, JuntiⅢ, and Jun-tiⅣon military physical performance capacity .Methods Fifty-four soldiers , selected from a border defense troop , were randomly designated to control group , trial group 1 and trial group 2.Subjects of two trial groups were supplied with No .1 nutritional package ( including JuntiⅠ, Ⅲand Ⅳ) and No.2 nutritional package ( including Junti Ⅱ, Ⅲand Ⅳ),re-spectively, while no additional nutritional supplements were added in control group .After 7 days’ supplementation, a hard military exercise was performed to induce fatigue and an increasing load test was used to assess physical activity .RPE scale, exhaustive time and time taken to reach the 75% maximal heart rate were recorded while serum markers , such as glucose, lactate, BUN, LDH,and CK, were detected after test .Moreover, serum lactate and fatigue recovery scale were determined on the evening of the same day and the next morning .Results Prolonged exhaustive time and time taken to reach the 75%maximal heart rate and elevated RPE scores at 6 min were detected in both two trial groups compared with the control group .Meanwhile , after the increasing load test , elevated glucose concentration and reduced lactate , BUN, LDH and CK were also observed in both trial groups .Moreover, serum lactate of both trial groups was quickly recovered on the evening of the same day compared with the control group , and the next morning , serum lactate was even much lower in trial groups than in control group .The fatigue recovery scores were higher in trial groups at both time points .Meanwhile, there was no difference of such indexes between the two trial groups .Conclusion Through the combination use , the series of special anti-fatigue foods, inclucling No.1 and No.2 nutritional packages , can significantly improve the soldiers′physi-cal performance capacity , delay the physical fatigue emergence , promote physical activity recovery and prevent military training injury.
ABSTRACT
@#Tiredness is a physiological phenomenon,inevitably appears in certain period of exercise.If the tiredness has not been eliminated promptly,it would roll up to fatigue.It is important to analyze the generation,evaluation and recovery of fatigue,to make people come back to training,working or studying as soon as possible.
