Effects On The Cardiopulmonary Function And The Exercise Capability Of Middle-aged Male Obesity

The purpose of study: With the development of modem scientific technology, economy, industry and agriculture, people's living surrounding, working conditions and lifestyle are undergoing change, which result in obesity due to excessive nutrition and lack of exercise. Obesity will affect the construction, function and exercise capability in some parts of the body before it turn into sickness. So it is drawing attention from both physiology and medical circles because of its harmless on people's body function and exercise capability. Currently, domestic and foreign studies of this issue are mostly focus on health, but not on function, especially on obese middle-aged male. Even those on cardiac functions are lay particular stress on lung functions of obese middle-aged people are much less, which result in the lack of monitor and study on lung function of moving. At the same time, studies on exercise capability ,as well as precision instrument using is not enough. To understand obese effect on cardiopulmonary function and physical quality through test.Instruments and methods: The research object are 40 males in their middle-age males, and half of them are obesity, the rest are normal. Analyzing body ingredient by using Korean VENES 5.5 Body Composition Analyzer .20 of which body fat percentage bigger than 25% is confirmed as obesity ( stature:170.9±9.2cm ;weight:86.8±4.8kg;age:49.2±3.8y;fat:29%).Then taking the other 20 normal objects as comparison group(stature:175.4±5.5cm;weight:67.5±8.6kg;age:51.3±4.6y;fat:19%). Testing heart function by using Japans ALOKA 5500 colored Dopplar ultrasound diagnosis instrument .Testing lung function by using American MAX=ⅡMatabolic System. Then carry on comparative analysis of experimental results of the above two group, which includes 50m ,set up the position body bends the waist ,grasp strength, myo-strenth, standing with one foot closed eyes.Experimental result: cardiac function: The obese groups'IVS is thicker than the normal ones(O:8.6±0.7mm,N:8.3±0.5),The obese groups'AO,LV,LVPW,ESV,EDV are much larger than the normal one(sO:30.6±2.5mm,48.7±2.0,9.5±1.5,33.8±6.2ml,97.7±14.7ml,N:28.6±0.9,42.5±9.3,8.63±1.46,31.0±7.7ml,89.1±15.0ml),The obese groups'CO,SV,HR are much higher than the normal ones(O:6.72±1.52L/min,86.2±9.5ml/beat,78±10 beat/min;N:6.0±1.4 ,79.0±10.0,70.9±12.2),The obese groups'FS,EF,E,A,E/A are lesser than the normal ones(O:39±7%,66±4%,60.0±11.1 cm/s,47.9±8.1 cm/s,1.24; N:42±6,71±3, 74.1±12.3,56.1±14.2,1.33)Pulmonary function: The obese groups'VT,VE,VO2max are higher than the normal ones(O:517±45ml,7.05±1.01l/min,3331±99ml/min,N:475±33,6.81±0.78,2892±102),The obese groups'VT/WT,VE/WT,VEmax/WT,VO2max/WT,Maxpulse are much lesser than the normal ones(O:5.6±0.7 ml/kg, 81.4±8.5 ml/min.kg, 88.9±6.5, ml/min.kg 36.2±4.9ml/min.kg, 15.2±0.9ml/beat; N: 6.9±1.0, 102.2±10.1, 98.9±5.7, 42.7±3.9, 17.6±1.0).Exercise capability: The obese groups'grasps the strength is smaller than the normal ones, but back myo- strength is stronger (O:51.2±6.2kg, 56.9±7.2 kg, 176.1±21.0 kg; N: 49.6±6.5, 53.6±7.1, 181.3±18.2),The obese groups'relative value of grasps the strength, the relative value of myo- strength are much lesser than the normal ones(O:0.69±0.71kg,0.76±0.59kg,2.29±0.18kg; N:0.79±0.49,0.821±0.84,2.92±0.45);the speed, flexibility, balance of obese groups are much lesser than the normal ones :50m, flexibility and balance(O:58±5分,3.6±4.8cm,8.0±2.1s,7.5±3.4s;N:70±9,6.3±3.2,10.3±3.0,11.2±4.1)。Discussion: Obesity already affected the heart structure and function of middle-aged male, which include heart wall ventricle thick and output increasing, with blood score decreasing and heart rate speeding up. As a result , the heart diastole function declined. Such phenomenon should arouse the society's concern and take efforts to control it. Obesity can cause the decline of oxygen ability , which showed in decreasing relative value of oxygen quantity absorbing .The physical quality of the obesity group is far less than that of comparison group, especially on speed, pliable and balance quality .Obesity had already affected people's heart and lung functions, oxygen ability and physical quality. Further more ,it is also the prelude that cause other modern disease; which should arouse the attention of the whole society .To control one's weight as soon as possible, reduce obesity rate, Above all, lighten the burden of individual, family and even the society.
