장기간(長期間) 체력단련(體力鍛鍊)이 심전도파고(心電圖波高) 및 심전도(心電圖) vector에 미치는 효과(效果)를 구명(究明)하고자 10명(名)의 운동선수군(運動選手群)과 13명(名)의 비운동선수군(非運動選手群)에서 rebounder운동전후(運動前後)의 심전도파고(心電圖波高)와 QRS vector의 길이를 측정(測定)하여 분절(分折)한 결과(結果)는 다음과 같다. 심전도파고(心電圖波高)에서 R파고(波高)는 선수군(選手群)이 23.38±1.14 mm로서 비선수군(非選手群)의 17.91±2.00 mm에 비(比)해 유의(有意)하게 높았고, 운동후(運動後)에도 선수군(選手群)이 계속(繼續) 유의(有意)하게 높았다. S파고(波高)는 양군(兩群) 모두 운동후(運動後)는 안정시(安靜時)에 비(比)해 유의(有意)하게 높았으며, T파고(波高)는 운동후(運動後) 감소(減少)하였다. P파고(波高)는 양군(兩群) 모두 운동후(運動後) 증가(增加)하였으며 선수군(選手群)이 다소 낮았다. PQ분절(分節)의 파고(波高)는 선수군(選手群)은 0인데 비(比)해 비선수군(非選手群)은 negative를 나타냈으며 운동후(運動後)에 유의(有意)하게 감소(減少)하였다. J점(點)은 양군(兩群) 모두 안정시(安靜時) positive에서 운동후(運動後) 유의(有意)하게 감소(減少)하여 negative를 나타냈고, J+0.08초(秒)도 운동후(運動後) 양군(兩群) 모두 감소(減少)하였으며 선수군(選手群)이 다소 높았다. 그러므로 ST분절(分節)은 운동후(運動後) 감소(減少)함을 알 수 있다. Rv₅와 Sv₁의 합(合)은 선수군(選手群)이 38.74±2.71 mm로서 비선수군(非選手群)의 32.28±2.90 mm에 비(比)해 높았으며 운동후(運動後)에도 선수군(選手群)이 유의(有意)하게 높았다. QRS vector 각도(角度)에서 Frontal plane에서 선수군(選手群)이 62.7±7.36˚로서 비선수군(非選手群)과 별(別) 차이(差異)가 없었고, horizontalplane에서는 선수군(選手群)이 -23.5±7.2˚로서 비선수군(非選手群)의 -38.8±8.2˚에 비(比)해 유의(有意)하게 높았으며 운동후(運動後) 양군(兩群) 모두 유의(有意)하게 높았다. QRS vector 길이에서 Frontal plane에서 선수군(選手群)이 13.86±1.44 mm로서 비선수군(非選手群)의 9.62±0.97 mm에 비(比)해 유의(有意)하게 높았으며 운동후(運動後)에도 유의(有意)하게 높았다. Horizontal plane에서도 선수군(選手群)이 19.82±2.10 mm로서 비선수군(非選手群)의 16.90±1.39 mm에 비(比)해 유의(有意)하게 높았고 운동후(運動後)에도 선수군(選手群)이 유의(有意)하게 높았다. 이상(以上)을 종합(綜合)해 보면 선수군(選手群)의 R파고(波高)가 비선수군(非選手群)에 비(比)해 운동후(運動後) 계속(繼續) 유의(有意)하게 높았고, Rv₅와 Sv₁파고(波高)의 합(合)이 38.74mm정도(程度)로 좌심실(左心室)이 비대(肥大)함을 알 수 있으며, 선수군(選手群)의 PQ분절파고(分節波高)와 ST분절(分節) 파고(波高)가 비선수군(非選手群)에 비(比)해 높고 운동후(運動後)에 양군(兩群) 모두 감소(減少)한 점(點)은 주목(注目)할만한 사실(事實)이며, 특(特)히 선수군(選手群)의 QRS vector의 길이가 모두 비선수군(非選手群)에 비(比)해 유의(有意)하게 긴점등(點等)으로 좌심실기능(左心室機能)이 우수(優秀)한 스포츠심장(心臟)임을 알 수 있으며, 선수군(選手群)과 비선수군(非選手群)을 평가(評價)할 수 있는 중요(重要)한 지표(指標)가 될 것으로 사료(思料)되는 바이다.

In an effort to elucidate the effect of physical training on the electrocardiographic amplitudes, QRS vector, axis and QRS vector amplitude, electrocardiograms were recorded before and 1, 5 and 10 minutes after 3 minute rebounder exercise in 23 healthy male students aged between 18 and 21 years in two groups of athletes and non-athletes. ECG amplitudes were measured from lead I, V₁ and V₅ and axis and amplitudes of QRS vectors were measured from lead I and III in frontal plane, from lead V₂ and lead V₆ in horizontal plane. The results obtained are summarized as follows. ECG amplitudes: The R wave amplitude was 23.38±1.14 mm in athletes which was higher than 17.91±2.00 mm in non-athletes. After exercise, the difference in two groups remained significant throughout the recovery period. The S wave amplitude was increased significantly, and the T wave amplitude was decreased in both groups after exercise. The P wave amplitude was increased in both groups after exercise, and it was lower in athletes than in non-athletes. The PQ segment amplitude was zero in athletes but negative in non-athletes than in the resting state. The J point amplitude was positive in resting state and was negative after exercise in both groups. J+0.08 sec point amplitude was also lowered after exercise, and it was higher in athletes than in non-athletes. Therefore the whole ST segment was proved to be decreased after exercise. The summated amplitude of R in V₅ plus S in V₁ was 38.74±2.71 mm in athletes which was higher than 32.82±2.90 mm in non-athletes. After exercise, it was also significantly higher in athletes than in non-athletes. Axis of QRS vector: In frontal plane, axis of QRS vector was 62.7±7.36˚ in athletes, it showed no significant difference between the two groups. In horizontal plane, axis of QRS vector was -23.5±7.2˚ in athletes which was significantly higher than -38.8±8.2˚ in non-athletes. After exercise, it was significantly higher than the resting state in both groups. Amplitude of QRS vector : In frontal plane, amplitude of QRS vector was 13.86±1.44 mm in athletes which was significantly higher than 9.62±0.97 mm in non-athletes. After exercise, it was also significantly higher in athletes than in non-athletes. In horizontal plane, amplitude of QRS vector was 19.82±2.10 mm in athletes which was significantly higher than 16.90±1.39 mm in non-athletes. After exercise, it was also significantly higher in athletes than in non-athletes. From the above, these results indicate that R wave amplitude in athletes was significantly higher than in non-athletes before and after exercise, and that the summated amplitude of R in V₅ plus S in V₁ in athletes was also 38.74±2.71 mm suggesting a left ventricular hypertrophy We should note that the PQ segment and ST segment amplitude were higher in athletes than in non-athletes, and they were decreased with exercise in both groups. In particular, the fact that amplitudes of QRS vector in frontal plane or in horizontal plane were significantly greater in athletes than in non-athletes may be an index in evaluating athletes.
