The Effect Of FATmax Exercise On The Constitution And Cardiovascular Function Of Obese Women

Objective:Along with sustained and rapid economic development and people's rising living standards,he elderly high glucose and high fat diet habits gradually increased,while activity and exercise ability declining,obesity has become an important factor affecting the health of the elderly population.The data reported by WHO shows that the number of obese people increases steadily in the world's major countries in recent years,and the number and proportion of obese people also showed an upward trend year by year in China.At present,China has entered the aging society by a large population,and the health of the elderly has been elevated to the national strategic level.How to improve the physical quality of the elderly has become of high importance.Aerobic exercise is an effective method of lose weight.The choice of sports intensity is the key for the elderly obese women lose weight.In 2001,Jeukendrup and Achten proposed fat metabolism in the unit time corresponding intensity for maximum strength of fat oxidation peak,the peak value of maximum fat oxidation rate.This intensity of the exercise is low intensity aerobic exercise.Most scholars have shown that low intensity aerobic exercise helps to improve the physical fitness and cardiovascular function of the elderly.If FATmax exercise can make elderly obese women physical and cardiovascular function improved,and achieve the effect of dietary fat reduction,it is reported seldom at home and abroad.The purpose of this study was to evaluate the effects of exercise training at the maximal fat oxidation(FATmax)intensity on physique and cardiovascular function in the obese elderly.Method: Select 50 old obese women as subjects,who have long-term exercise habits and can ensure exercise more than 3 hours a week.They don't have diabetes,cardiovascular disease,osteoarthritis and others.Obesity judgment standard according to the adult body fat grading reference standard”:body fat percentage > 30%.Use conventional physical methods to measure height and weight,waist circumference,hip circumference,vital capacity,grip strength,reaction time,body antexion and dynamic balance;body composition was measured by dual energy X-ray absorptiometry America GE;use Japanese visceral fat analyzer AB-140 M measurement of abdominal fat and visceral fat;use Japanese Aloka SSD-118 ultrasound cardiotachograph to take cardiac echocardiography test;use the Japanese OMRON blood pressure and pulse tester HEM-9000 AI augmentation index(AI)determination;use the German Ergoselect100 series vertical power bicycle and telemetric instrument determination of maximal oxygen uptake pwc130 test;use German h/p/cosmos power running,Cortex ML3 B gas analyzer for FATmax testing,monitoring the blood pressure and use Tango motion tester in motion.According to the test of FATmax finalized formulates movement plan.FATmax group take a12 weeks,3 times a week,every time 1 hour FATmax strength training exercise for weight loss.Exercise program includes: preparing for 10 minutes;FATmax intensity of walking,about 30 minutes;the upper and lower extremities stretching and stretching for about 10 minutes;organize activities for about 10 minutes.After exercise intervention,the indexes were measured again,and the test instruments and instruments were all in accordance with the experiment.Two data for statistical analysis.Result: 1.The average maximal fat oxidation rate(FATmax Rate)of the elderly obese women was 0.35±0.12g/min,and the corresponding oxygen uptake(FATmax)accounted for39.01±8.76%VO2max,corresponding to an average heart rate of 102.20±8.35b/min.2.After 12 weeks of FATmax exercise intervention,the experimental group's BMI,waist circumference,waisthip ratio,body fat percent,abdominal fat percent and visceral fat level had been improved(p<0.05);compare with the control group,the experimental group's body weight,BMI,waist circumference,waist hip ratio,body fat%,abdominal fat% and visceral fat level were significantly improved(p<0.05),and the visceral fat level changes are very significant(p<0.01);there was no significant difference between the control group;no significant changes in other indicators.3.After 12 weeks FATmax exercise intervention,the experimental group's grip strength and dynamic balance are improved significantly(p<0.05);compared with the control group,the dynamic balance,vital capacity weight index,grip strength,reaction time were significantly improved(p<0.05),and the dynamic balance changes are very significant(p<0.01).4.After 12 weeks FATmax exercise intervention,the experimental group's AI,VO2 max,cardiac output are improved significantly(p<0.05),and the VO2 max changes are very significant(p<0.01);compared with the control group,systolic blood pressure,diastolic blood pressure,AI,VO2 max,cardiac output and LVEF were significantly improved(p<0.05),and VO2 max and LVEF changes are very significant(p<0.01).5.After 12 weeks FATmax exercise intervention,the experimental group's TG and HDL are improved significantly(p<0.05),and HDL changes are very significant(p<0.01);compared with the control group,TG and HDL were significantly improved(p<0.05).Conclusion:1 the average maximal fat oxidation rate(FATmax Rate)of the elderly obese women was 0.35±0.12g/min,and the corresponding oxygen uptake(FATmax)accounted for more than 39.01±8.76%VO2max,corresponding to an average heart rate of 102.20±8.35b/min.2 elderly obese women in the implementation of the 12 week FATmax intensity exercise weight loss program,physical condition,cardiovascular function and other indicators have been improved.3 the FATmax intensity exercise weight loss program can effectively achieve the effect of weight loss,and it is safe and effective,which provides a good reference for the elderly women's weight loss program.
