Caffeine Supplementation and muscle damage in soccer players BJPS
Machado,Marco; Breder,Anselmo Carvalho; Ximenes,Marcio Carvalho; Simões,Jarbas Rodrigues; Vigo,José Fábio Florentino.
The aim of this work was to evaluate the effect of caffeine supplementation and intermittent exercise on the muscle injury markers in soccer players. 15 male professional soccer players completed a placebo controlled double blind test protocol. 45 minutes before exercise, participants ingested 5.5 mg.kg-1 body mass of caffeine (EXP, n=8) or placebo (CONT, n=7). The exercise was 12 sets of 10 sprints (20 m each) with 10 sec recovery time between sprints and 2 min between sets. Blood samples were collected before (PRE) and 48h after exercise (POST). Serum activity of CK, LDH, AST, and ALT were quantified. Serum enzyme activity was enhanced by exercise in both groups, without a synergistic effect of caffeine. The findings suggest muscle injury markers...

Efeito de dietas com adição de óleo e do treinamento sobre a atividade muscular de equinos submetidos à prova de resistência - DOI: 10.4025/actascianimsci.v30i3.5714 Animal Sciences

O trabalho teve como objetivo verificar o efeito da adição de óleo de soja e do treinamento na atividade plasmática das enzimas Creatina Quinase (CK) e Aspartato Aminotransferase (AST) sobre o trabalho muscular de equinos submetidos a teste de resistência. Foram fornecidas dietas experimentais compostas por cinco níveis de óleo de soja no concentrado (controle, 6, 12, 18 e 24%). Foram utilizados 20 equinos da raça Árabe, peso médio de 400 kg, submetidos a teste de resistência de 80 km em esteira rolante, em Laboratório de Fisiologia do Exercício. A simulação de enduro foi dividida em quatro fases de 20 km cada. Observou-se efeito (p < 0,05) da adição de óleo e da distância percorrida sobre as variáveis AST e CK durante o enduro e também no período de...

Effect of Citrus aurantium L. Essential Oil on Muscle Regeneration in Mdx Mice International Journal of Morphology
De Souza,Paula Aiello Tomé; Marques,Maria Júlia; Lima,Clélia Akiko Hiruma; Matheus,Selma Maria Michelin.
Duchenne muscular dystrophy (DMD) is a severe X-linked recessive disorder characterized by the progressive loss of muscular strength. Mdx mutant mice show a marked deficiency in dystrophin, which was related to muscle membrane stability. The aim of this study was to verify the possible protective anti-inflammatory effect of citrus oil on mdx muscle fibers. Thus, adult male and female mdx mice (014/06-CEEA) were divided into control and citrus-treated. After 60 days of treatment, one ml of blood was collected for creatine kinase (CK) test. Diaphragm, sternomastoideus, anterior tibial and gastrocnemius muscles were removed and processed according to histological routine methods. The observed alterations indicate a direct effect of citrus. Recent studies have...

Effect of suramin on myotoxicity of some crotalid snake venoms BJMBR
Arruda,E.Z.; Silva,N.M.V.; Moraes,R.A.M.; Melo,P.A..
We investigated the protective effect of suramin, an enzyme inhibitor and an uncoupler of G protein from receptors, on the myotoxic activity in mice of different crotalid snake venoms (A.c. laticinctus, C.v. viridis, C.d. terrificus, B. jararacussu, B. moojeni, B. alternatus, B. jararaca, L. muta). Myotoxicity was evaluated in vivo by injecting im the venoms (0.5 or 1.0 mg/kg) dissolved in physiological saline solution (0.1 ml) and measuring plasma creatine kinase (CK) activity. Two experimental approaches were used in mice (N = 5 for each group). In protocol A, 1 mg of each venom was incubated with 1.0 mg suramin (15 min, 37ºC, in vitro), and then injected im into the mice at a dose of 1.0 mg/kg (in vivo). In protocol B, venoms, 1.0 mg/kg, were injected...

Evaluation of Physiological Parameters of Broilers with Dorsal Cranial Myopathy Rev. Bras. Ciênc. Avic.
Amaral,PC; Zimermann,C; Santos,LR; Noro,M; Prá,MD; Pilotto,F; Rodrigues,LB; Dickel,EL.
ABSTRACT There are several causes of carcass condemnation in poultry processing plants, including dorsal cranial myopathy (DCM), in which the anterior latissimus dorsi (ALD) muscle is affected. DCM etiology has not been elucidated yet, but this lesion impairs the visual quality of carcasses and causes economic losses due to downgrading and condemnation. The effects of this lesion on the systemic health of broilers are still unknown. In this context, the objective of this study was to evaluate muscle injury and systemic health indicators in broilers presenting or not DCM. The following parameters were evaluated: complete blood count (CBC), total protein, albumin, globulin, cholesterol, lactate, and glucose serum levels, aspartate aminotransferase (AST) and...

Serum concentrations of creatine kinase and of triglycerides during lactation in gilts bred older and in multiparous sows fed ad libitum Arq. Bras. Med. Vet. Zootec.
Nogueira,R.H.G.; Guedes,R.M.C.; Souza,J.C.A..
The aim of this paper was to assess the possible variation in blood concentrations of creatine kinase (CK) and triglycerides in gilts bred older in comparison with multiparous sows. Ten primiparous and ten Camborough multiparous sows from the fourth to seventh parities were used. Breeding age and weight of gilts averaged respectively 231 days and 149.5kg. All females were moved into individual farrowing crates and were managed under the same conditions. Blood samples were collected by puncturing the coccygeal artery on day 7 before expected farrowing, and on days 2, 7, 14, 21 of lactation and 2 days after weaning. No difference in triglycerides and CK serum concentrations between groups were observed. The CK levels were low before farrowing, increased...
