Exercise training of dogs with myxomatous valve disease / Treinamento físico de cães com doença mixomatosa valvar

The present study has the objective of evaluating the effects of exercise training, using moderate intensity walking (60 to 80% of maximum heart rate), from 30 to 50 minutes, three times a week, in alternate days, during eight weeks, on heart rate variability in dogs with myxomatous valve disease (MVD). For that, 20 dogs in stages B1 (1), B2 (14) and C2 (5) of MVD (ACVIM classification) were divided into untrained control group (CG, n=9) and training group (TG, n=11), and assessed at baseline (T0), after four (T1) and eight weeks (T2). Only one B1 and five B2 dogs completed the training program. In the time domain, the rMSSD was greater in TG in T1 (155,5+42,07) and T2 (199,8+83,54) than CG (T1:91,17+35,79 and T2:88,17+57,51). In the frequency domain, the variable High Frequency (HF) increased in TG in T1 (30950+25810) and T2 (40300+33870) when compared to the CG (T1:19090+23210 and T2:18810+22200) and within the group TG in T2 in relation to T0 (29340+20950). The proposed walking protocol is concluded to have increased the rMSSD and HF variables in TG, representing an increase of the parasympathetic tonus, justifying the indication of this therapy in B1 and B2 stages of MVD.(AU)

O presente estudo objetivou avaliar o efeito do treinamento físico, utilizando-se a caminhada de moderada intensidade (60 a 80% da frequência cardíaca máxima), por 30 a 50 minutos, três vezes por semana, em dias alternados, durante oito semanas, sobre a variabilidade da frequência cardíaca em cães com degeneração mixomatosa valvar (DMV). Para tanto, 20 cães nos estágios B1 (1), B2 (14) e C2 (5) da DMV (classificação ACVIM) foram divididos em grupo controle não treinado (GC, n=9) e grupo treinamento (GT, n=11) e avaliados no início do estudo (T0), após quatro (T1) e oito semanas (T2). Apenas um cão B1 e cinco B2 completaram o programa de treinamento. No domínio do tempo, a variável rMSSD foi maior no GT em T1 (155,5+42,07) e T2 (199,8+83,54) que o GC (T1:91,17+35,79 e T2:88,17+57,51). No domínio da frequência, a variável High Frequency (HF) aumentou no GT em T1 (30950+25810) e T2 (40300+33870) comparada à do GC (T1:19090+23210 e T2:18810+22200), e dentro do GT no T2 em relação ao T0 (29340+20950). Dessa forma, conclui-se que o protocolo de treinamento proposto aumentou as variáveis rMSSD e HF no GT, representando aumento do tônus parassimpático, o que fundamenta a indicação dessa terapia nos estágios B1 e B2 da DMV.(AU)

Effect of Regular Physical Exercise (Among Circus Athlets) on Lipid Profile, Lipid Peroxidation and Enzymatic Antioxidants.

The study was planned to see the effect of regular physical exercise on levels of lipid profile, activity of lecithin cholesterol acyl transferase, lipid peroxidation and antioxidant enzymes in those involved in regular physical exercise (among athlete in circus) and those involved in sedentary lifestyle. Study Design: Cross sectional study. Place and Duration of Study: The study was carried out during September 2012 to December 2012 in the department of biochemistry, BIMS, Belgaum. Methodology: A total of 70 participants were studied, aged 25-55 years. Group I consists of 35 participants working as circus athletes, involved in regular physical exercise. Group II consisted of 35 age and sex matched healthy controls, with sedentary life style. Total cholesterol and HDL cholesterol were measured by CHOD-PAP method. Triglyceride was measured by GPO-PAP method. LDL and VLDL were calculated by formula. MDA was determined as the measure of thiobarbituric acid reactive substances (TBARS). SOD Catalase and GPX activity was determined by the method of Mishra and Fridovich, Beer and Seazer and Paglia and Valentine respectively. Results: The levels of lipid peroxide, TC, TC / HDL and LDL / HDL ratio were significantly lowered in Group I on comparison with Group II. The levels of HDL, activity of SOD, GPX and catalase were significantly higher in Group I on comparison with Group II. Individuals engaged in regular physical activity had lowered levels of atherogenic lipid components and subjects with sedentary lifestyles had higher atherogenic lipid components (lipid profile and lipid peroxide). Conclusion: The study indicates that engaging in regular physical exercise protects cardiovascular diseases by increasing the HDL Cholesterol levels, activity of LCAT enzyme and activity of antioxidant enzymes. Thus regular physical exercise is an important in the protection of atherosclerosis and management cardiovascular disease.

A comparative study of lipid profile of sports persons and sedentary persons.

Background and objective: - Regular physical exercise in any form makes lipid profile favorable and reduces the chances of heart attacks and brain strokes. Our aim was to find out the effect of regular physical exercise on lipid profile, compare and analyze the results of sports persons and sedentary persons. Methodology: - The present work was carried out in the Indian Petro Chemical Ltd sports complex and IPCL Hospital situated in Vadodara city. Lipid profile test was carried out on the sportsperson and the control group using instrument named VITROS – 750, which is an automatic analyzer. Results: - The result was compared by statistical analysis that revealed total serum cholesterol, Low density lipoprotein cholesterol, Very low density lipoprotein and Serum Triglyceride showed significantly higher values and High density lipoprotein cholesterol showed significantly lower values in control subjects when compared with the sports persons. Conclusion: - It can be concluded that regular physical exercise in the form of sports, aerobics or workouts leads to more favorable cardio-vascular risk factors profile that improves the quality and duration of life.

Effect of Regular Physical Exercise on Physical Fitness Level in Nursing Students / 기본간호학회지

This study was to test the relationship between regular physical exercise and physical fitness in nursing students. These subjects were 54 volunteers who agreed with intention of this study and were composed of 24 active group and 30 non-active group. The selected physical fitness tests were grip strength and back strength for measuring muscular strength, sargent jump and standing broad jump for measuring power, push-up, sit-up, and heart rate for measuring total for measuring agility, stick test and stork stand for measuring balance, and trunk flexion and trunk extension for measuring flexibility. The conclusion acquired was as follows : 1) Grip strength had significant difference between active group of 29.5+/-5.9kg and non-active group 25.4+/-7.2kg(t=2.283, p=.027), and back strength between active group of 54.1+/-13.7kg and non-active group of 44.7+/-15.7kg(t=2.310, p=.025). 2) Sargent jump was lower with non-active group(44.9+/-8.6cm) than with active group(45.3+/-8.8cm), however, was not significant(t=.182, p=.856). Standing broad jump was significantly lower with non-active group of 161.3+/-28.7cm than with active group of 191.4+/-27.0cm(t=3.939, p=.000). 3) Push-up showed significant difference between active group of 25.3+/-12.3times and non-active group of 11.5+/-5.1 times(t=5.572, p=.000), and sit-up between active group of 21.8+/-7.4times and non-active group of 17.1+/-5.8times(t=2.631, p=.011), and heart rate between active group of 110.5+/-12.8beats/min and non-active group of 121.5+/-9.5beats/min(t=-3.648, p=.001). 4) Reaction time was significantly higher with non-active group of .300+/-.051sec than with active group of .341+/-.041sec(t=-3.285, p=.002). Side step test was lower with non-active group(8.8+/-1.1times) than with active group(9.2+/-1.2times), however, was not significant(t=1.309, p=.196). 5) Stick test showed not significant difference between active group of 25.8+/-14.8sec and non-active of 30.7+/-17.9sec(t=-1.058, p=.295), and stork stand between active group of 4.5+/-3.2sec and non-active group of 3.7+/-3.5sec(t=.918, p=.363). 6) Trunk flexion came out not significant difference between active group of 14.2+/-5.0cm and non-active group of 15.8+/-7.3cm(t=-.927, p=.358), and trunk extension between active group of 67.1+/-6.5cm and non-active group of 67.3+/-6.6cm(t=-.140, p=.889). 7) Power was shown to be significantly related to total endurance(r=.717, p=.000; r-.739, p=.000). 8) Total endurance was shown to be significantly related to agility(r=-.752, p=.000; r=.684, p=.000; r=-.664, p=.000; r=.598, p=.002; r=.864, p=.000; r=-.536, p=.007). These results suggest that regular physical exercise is effective in promoting and maintaining physical fitness. As the further study, it is necessary to reinvestigate the effect with more refined design.
