A study on the comparison of physical fitness and cardiovascular function between middle school soccers and untrained Students

&nbsp;&nbsp;The purpose of this study was to investigate differences of the physical fitness and the cardiovascular function between some trained Football players(TFP) and some untrained Students(US). The subjects are 20 persons, respectly.<BR>&nbsp;&nbsp;I adopted the physical test and used tread-mill to understand the effect of aerobic exercise and to know the physical fitness and developing states of the sampled young students.<BR>&nbsp;&nbsp;The results of this study are as follows:<BR>&nbsp;&nbsp;1. In terms of the height, weight, and chest, there were not any remarkable difference between TFP and US.<BR>&nbsp;&nbsp;2. No significant difference appeared in terms of grip strength, Arm strength flexion, Arm strength extension, Leg strength flexion, Leg strength extension, Trunk flexion and Trunk extension between the 2 groups. In the back strength, however, there was a remarkable difference(p＜0.05) between TFP(43.70±7.18㎏) and US(35.5±2.45㎏).<BR>&nbsp;&nbsp;3. In the percentage of the fat, there was a significant difference(p＜0.01) between TFP(15.13±2.28%)and US(21.13±7.83%).<BR>&nbsp;&nbsp;4. In TVe, I could not find any significant difference between them at rest in warm-up, all-out, 5-minute recovery.<BR>&nbsp;&nbsp;In the maximum tidal volume, It showed that three was significant difference(p＜0.05) between TFP (2038.85±350.40㎖) and US(1792.10±299.44㎖).<BR>&nbsp;&nbsp;5. In Ve, there was no significant difference in the ventilations in the rest, warm-up, and 5-minute recovery. But in the maximun ventilation(Ve max), It showed that there was a remarkable difference(p＜0.001) between TFP(123.58±22.38㎖/min) and US(97.18±21.55㎖/min). and there was a notable difference(p＜0.01) between TFP(113.40±23.29㎖/min) and US(89.09±19.51㎖/min) in all-out.<BR>&nbsp;&nbsp;6. In respiration rate(R.R), while there was no remarkable difference in warm-up and 5-minute recovery. It showed that there was a notable difference(p＜0.05) between TFP(20.88±6.79n/min) and US(26.42±7.86n/min).<BR>&nbsp;&nbsp;It also showed that there was a remarkable difference(p＜0.01) between TFP(62.70±6.52n/min) and US(69.88±9.44n/min). In all-out, It showed that there was a notable difference(p＜0.001) between TFP(54.30±6.76n/min) and US(63.02±7.36n/min).<BR>&nbsp;&nbsp;7. In heart rate, It showed that there was a significant difference(p＜0.001) between TFP(68.18±15.63beats/min) and US(83.03±8.84beats/min) at rest.<BR>&nbsp;&nbsp;In warm-up, It showed that there was a big difference(p＜0.01) between TFP(87.13±21.91beats/min) and US(109.57±10.23beats/min).<BR>&nbsp;&nbsp;In maximum heart rate, It showed that there was a big difference(p＜0.001) between TFP(191.46±8.52beats/min) and US(200.27±6.16beats/min) In average heart rate of all-out, It showed that there was a significant difference(p＜0.01) between US(199.11±18.10beats/min) and TFP(185.22±6.07beats/min) In average heart rate of 5minute recovery, It showed that there was a big difference(p＜0.001) between TFP(105.42±11.69beats/min) and US(118.39±8.55beats/min).<BR>&nbsp;&nbsp;8. In 02 pulse, while there was no big difference at rest and in warm-up, 5-minute recovery, a significant(p＜0.001) was shown in the maximum O₂ pulse between TFP(16.34±3.09㎖/beats) and US(12.85±2.38㎖/beats). In all-out, It showed that there was a remarkable difference(p＜0.05) between TFP(14.39±3.84㎖/beats) and US(11.80±2.32㎖/beats).<BR>&nbsp;&nbsp;9. The oxygen intakes recorded between the two groups were not different in the warm-up and 5-recovery conditions, but at the other hand in the rest condition a notable difference(p＜0.01) appeared between TFP(388.43±70.05㎖/min)and US(300.43±115.89㎖/min). In maximum oxygen intakes. It showed that there was a big difference(p＜0.01) between TFP(3120.35±509.89㎖/min) and US (2510.47±503.42㎖/min). In all-out, those also showed a very notable difference(p＜0.001) between TFP(2984.30±427.95㎖/min) and US(2288.63±443.44㎖/min).<BR>&n
