Twenty college students in their twenties with weak sperm motility or low sperm count were subject to 12 weeks of Acantheopanax senticosus tea drinking. As a result, their continuous aerobic exercise time was increased, blood lactate concentration during exercise was reduced and sperm motility and sperm count were improved. These results show the effectiveness of the homegrown Acantheopanax senticosus to the declining male fertility affected by factors such as endocrine disruptors. Further research on the medicinal effect of native Acantheopanax senticosus on improving the fertility is necessary on various factors that cause the decrease in fertility.

본 연구에서는 6주간의 평압·저산소 트레이닝을 실시하는 동안 2주마다 최대 하 부하 자전거 운동 시의 산소섭취량, 혈중 젖산농도, 혈액의 산·염기 평형, 운동수행능력 등의 변화를 평지조건에서 비교함으로써 간헐적인 평압·저산소 트레이닝의 장·단기적인 효과를 설명하는데 목적을 두었다. 이를 위해 건강한 남자 대학생들을 산소농도 16.5%(2,000m 상당고도)의 평압·저산소 조건과 산소농도 20.93%의 평지조건에서 각각 트레이닝을 실시토록 하였다. 그 결과, 트레이닝 후 운동부하량(대조: 20.7%, 실험: 29.1%)과 목표 심박수 도달시간(대조: 6.0%, 실험: 19.4%)이 유의하게 향상되었으며 목표 심박수 도달시간의 증가는 실험집단에서 트레이닝 2~4주차 사이에 큰 폭으로 증가하였다. 또한 실험집단의 운동 중 HCO3-의 농도는 트레이닝에 따라 낮아졌으나 pH의 변화는 보이지 않았다. 이는 평압·저산 트레이닝에 의해 저산소 환기응답이 개선되어 운동 중 호흡을 통한 CO2의 제거가 원활해짐으로써 HCO3-감소와 같은 대사성 산성증에 대한 보상능력이 향상되었기 때문으로 생각한다. 따라서 16.5%(2,000 m 상당고도)의 평압·저산소 조건에서 80%HRmax로 60분의 단기간 간헐적인 운동 트레이닝을 실시하는 경우, 트레이닝 2~4주 이내에 평지 운동수행능력이 향상되는 것을 알 수 있었다. This study was designed to investigate the effect of short and long duration intermittent normobaric hypoxia training on breathing gas, blood lactate concentration, blood acid-base balance, and performance in submaximal bike exercise every two weeks during six weeks. For the purpose of this study, male collegian trained in 16.5%O2(Experimental group: E) and 20.93%O2(Control group: C) during six weeks. Also, all subject estimated in breathing gas, blood lactate concentration, blood acid-base balance. As a result, workload(C: 20.7%, E: 29.1%) and time to target HR significant improved. Clearly improvement of time to target HR presented 2~4 weeks training duration in E. Also, concentration of HCO3-in exercise decreased followed training but change of pH don`t presented. These results thought normobaric hypoxia training decreased HCO3-throughout improve compensation of metabolic acidosis because enhancement of hypoxia ventilator response that CO2 elimination in breath during exercise. Therefore, sea level exercise performance increased within 2~4 weeks training through 80%HRmax intermittent exercise training during 60min in 16.5% normobaric hypoxia (2,000m altitude).

The purpose of this study was to compare the anthropometric parameters, anaerobic power, isometric peak torque, and isokinetic muscle performance of the college male taekwondo players, female taekwondo players, and female soccer players. Sargent jump was estimated for the anaerobic power. Maximal voluntary force in knee extension was measured before and after a muscle endurance test (MET) by using a Cybex 350 isokinetic dynamometer isometrically at 90˚and con-centrically at the angular velocity of 30˚, 120˚, and 270˚·S-¹, The MET conists of 30 maximal concentric muscle actions at the angular velocity of 270˚·S-¹. The significant group differences were observed in %fat(p<.05) and the male taekwondo players demonstrated the highest mean values. A significant difference (p<.05) was observed in sargent jump between male taekwondo players and female players. The male taekwondo players showed the highest mean value, followed by female soccer and female taekwondo players. In isometric and isokinetic muscular strength test the male taekwondo players showed a significant difference(p<.05) from the female athletes before MET and no differences were found between female taekwondo and soccer players. The similar results in isometric and isokinetic muscular strength were observed after MET except that no significant differences exist between male taekwondo and female soccer players. These results indicates that the correlation exists between sargent jump and knee extension forces. Male taekwondo players showed a significant differences from the female players in total work of MET(p<.01). However, no significant difference were observed between the subjects in knee extension endurance ratio and flexion endurance ratio and recovery ratio. The female taekwondo players showed statistically higher values compared to female soccer and male taekwondo players(p<.05) in recovery ratio of MET. Therefore, it is assumed that there exist gender differences in the muscular endurance, and further research is needed on this issue.
