A study on isokinetic muscular function, aerobic and anaerobie capacity in elite gymnasts

&nbsp;&nbsp;The purpose of this study was to determine the characteristics of muscular function, aerobic and anaerobic power in elite gymnasts.<BR>&nbsp;&nbsp;The subjects of this study were consisted of 9 male high school and university gymnasts as non-elite group, and 9 male high school and university gymnasts as elite group.<BR>&nbsp;&nbsp;Treadmill, gas analyzer, bicycle ergometer and cybex-Ⅱ were used measure the aerobic power, anaerobic power and isokinetic muscle function respectively.<BR>&nbsp;&nbsp;The main findings of this study were as following<BR>&nbsp;&nbsp;1. Muscular function<BR>&nbsp;&nbsp;1) Maximal strengths at knee joint, elbow joint and wrist joint were not different between groups.<BR>&nbsp;&nbsp;At flexion at wrist joint, those of elite gymnast groups was 20% as high as those of non-elite gymnast group, but the difference between groups was insignificant.<BR>&nbsp;&nbsp;Maximal strength ratio at knee joint and wrist joint in elite gymnast group were significantly higher than those in non-elite gymnast group (p＜0.05 and p＜0.01, respectively).<BR>&nbsp;&nbsp;But that at elbow joint did not show difference between two groups.<BR>&nbsp;&nbsp;2) Power during flexion and extension at knee joint, and power during pronation and supination at elbow joint were not different between two groups.<BR>&nbsp;&nbsp;In elite gymnast group, power during flexion at wrist joint was significantly higher than that in non-elite gymnast group(p＜0.05).<BR>&nbsp;&nbsp;At knee joint power ratio at test speed of 180°/sec was 69.2% in elite gymnast group, and was 65.3% in non-elite gymnast group, difference of power ratio between groups was significant(p＜0.05).<BR>&nbsp;&nbsp;3) Muscular endurance at wrist joint in elite gymnast group was significantly higher than that in non-elite gymnast group both flexion and extensiop(p＜0.001 and p＜0.01, respectively).<BR>&nbsp;&nbsp;4) Work during flexion and extension at knee joint did not show significant difference between groups.<BR>&nbsp;&nbsp;And work during pronation and supination at elbow joint did not show significat difference between groups.<BR>&nbsp;&nbsp;But, at wrist joint, work during extention in elite gymnast group was significantly higher than that in non-elite gymnast grou(p＜0.05).<BR>&nbsp;&nbsp;Work during flexion in elite gymnast group show significantly higher than that in non-elite gymnast grou(p＜0.05).<BR>&nbsp;&nbsp;2. Aerobic power<BR>&nbsp;&nbsp;VO₂&lt;SUB&gt;max&lt;/SUB&gt; did not show significant difference between elite gymnast group and non-elite gymnast group(57.1±1.5㎖/㎏/min and 57.3±2.0㎖/㎏/min, respectively).<BR>&nbsp;&nbsp;VE&lt;SUB&gt;max&lt;/SUB&gt; of elite gymnast group was 109.81/min and VE&lt;SUB&gt;max&lt;/SUB&gt; of non-elite gymnast group was 116.32±12.81/min, but the difference between groups was not significant.<BR>&nbsp;&nbsp;3. Anaerobic power<BR>&nbsp;&nbsp;The anaerobic peak power for 30-s wingate test did not show significant difference between elite gymnast group and non-elite gymnast group.<BR>&nbsp;&nbsp;And mean powers were not difference between groups.<BR>&nbsp;&nbsp;After wingate test, blood lactate concentration in elite gymnast group was higher than blood lactate concentation in non-elite gymnast group, but the difference between groups was nonsignificant.<BR>&nbsp;&nbsp;As the result of this study, we concluded that the elite gymnasts are not different from the non-elite gymnasts min aerobic power and muscular functions at knee joint and elbow joint, but muscular functions at wrist joint in elite gymnasts are more prominant than those non-elite gymnasts.
