Purpose: This study was conducted to investigate the muscular strength & stamina improvement and muscle anti-fatigue effects of Morinda officinalis How after long term administration. Methods: 4-6 weeks old ICR mice were used in this study and we administered the water soluble extracts of Morinda officinalis How in the concentration of 1, 10. 100/mg/0.3ml to each 5 mice (ATS group) and same volume of normal saline was administered to 5 mice (control group) once a day for 90 or 120 days. After the administration we performed the swimming exercise test and the grip strength test. And we measured the concentration of glucose and the activity of lactate dehydrogenase in plasma regarded as biochemical indicator related with the muscular fatigue. Results: In swimming exercise test, all ATS groups showed increased time compared with relative control group after 90 days administration. After 120 days adminstration 100/mg/0.3ml ATS groups showed increased results. In grip strength test, all ATS groups showed increased grip strength compared with relative control group after 90 days administration. After 120 days adminstration 10/mg/0.3ml ATS groups showed increased result. All the results of plasma glucose didn't showed statistically significant difference after 90 and 120 days administration. In the plasma concentration of activity level of lactate dehydrogenase, all ATS groups didn't showed statistically significant difference compared after 90 days administration. Conclusion: This study show that Morinda officinalis How can increase the muscular strength & stamina and anti-fatigue effect.

Lepidium meyenii, known as Maca, is traditionally employed in the Andean region for its supposed properties to improve energy and fertility. In the present study, we investigated the effects of gelatinized and fermented Maca on improvement of physical stamina and epididymal sperm counts, and on blood biochemical parameters related to fatigue and tissue injury: creatine phosphokinase, aspartate transaminase, lactate dehydrogenase, blood urea nitrogen, glucose, total cholesterol and total proteins. Adult male mice was divided at random into two main groups (resting and excercise groups). The excercise group was separated into three subgroups (exercise only, exercise with gelatinized Maca and fermented Maca-treatment groups). Gelatinized or fermented Maca (800 mg/kg) were orally administered for 30 days. All animals in exercise groups were subjected to daily 30-min swimming for 28 days 30 min after Maca treatment. Daily exercise decreased the body weight gain, and fermented Maca further attenuated the body weight increase. Gelatinized and fermented Maca significantly increased the maximum swimming time on 14 and 28 days of treatment (p<0.05), respectively, suggestive of a long-term stamina-enhancing effect of fermented Maca. Both Maca fully or significantly recovered blood parameters of energy as well as muscular and hepatocytic injuries changed by repeated exercise and maximum swimming performance (p<0.01). Moreover, gelatinized and fermented Maca increased epididymal sperm counts 22.0% and 32.0%, respectively. In conclusion, the results indicate potential benefits of Maca for improving both physical stamina by minimizing muscular and hepatic damage and preserving energy during swimming exercise and male reproductive function by increasing epididymal sperm counts.

Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.

본 연구는 성인병 질환자 및 정상 노인을 대상으로 적정 강도의 유산소 운동 근력운동을 병행한 복합운동 프로그램을 24주간 실시한 후 신체구성, 혈액성분, 체력의 변화가 운동 전 후 어떠한 차이를 나타내는지 비교하고 성인병 질환자들을 위한 가장 효과적인 복합운동 프로그램을 작성하는데 목적이 있다. 이를 위하여 K도시에 거주하는 만 65세 이상의 성인병 질환자 20명과 정상노인 20명을 선정하여 이들에게 24주간의 복합 운동을 규칙적으로 실시하도록 하였다. 연구 결과로 신체구성의 변화는 성인병 집단의 경우 모두 유의하게 증가하였으나 정상인 집단은 복부지방률만 유의하게 나타났다. 혈액성분의 변화는 정상군에서 근소한 차이로 향상되는 결과를 보였으나, 유질환군과 근소한 차이를 보여 프로그램 전 후 상호작용은 유의한 차이가 없다. 프로그램 실시 전 후 근력, 각근력, 민첩성, 근지구력, 평형성에 있어 유의한 차이를 보이며 두 집단 모두 체력의 긍정적 향상 결과를 보였다. 정상인 집단에서는 건강을 유지하고 체력향상에 효과적이었고 성인병 집단에서는 질환의 예방과 악화 방지에 긍정적 요소가 나타났다고 볼 수 있다. 더불어 전 노인 인구의 50% 이상이 한 가지 이상의 성인병 질환을 가지고 있으면서도 운동의 참여도가 현저히 저하되는 현실 속에서 적극적인 운동 프로그램을 개발하여 복합운동 프로그램을 실시한다면 건강증진은 물론 삶의 질적 향상에 도움이 될 것이고 차후 보다 많은 연구가 필요할 것이라 사료 된다.
