Description

  The present invention relates to endurance improvers, anti-fatigue agents, muscle strength improvers, motor function improvers, and aging inhibitors for exercise in a broad sense.

  In recent years, with the development of transportation means and the development of information and communication technology, there is a lack of exercise. Lack of exercise is considered to cause a decrease in motor function such as a decrease in endurance and a decrease in muscle strength, and a serious adverse effect on the subsequent QOL.

  Muscle atrophy, endurance, and a decrease in muscle strength associated with aging decrease motor function and cause bedridden. In addition, falls during daily movements caused by muscle atrophy and weakness, and the accompanying fractures are the main cause of bedridden in elderly people.

  Therefore, in order to improve and maintain daily life functions and extend a healthy life span, it is important to maintain or enhance motor functions on a daily basis and to suppress a decrease in motor functions associated with aging.

  It may be appropriate to perform exercise training to improve motor function, but people who cannot get enough exercise time due to their busyness or who get tired immediately after exercising will continue. Many people are unable to exercise. In elderly people, practicing moderate exercise or practicing rehabilitation is used as a means to prevent a decline in motor ability. However, in reality, it may be difficult to maintain motivation or injuries. It is quite difficult and a more effective method is desired.

  As one means for solving these problems, it is conceivable to ingest daily food components having an action function improving action such as endurance and muscle strength and an anti-fatigue action. For example, the present inventors have found an endurance improvement effect by ingesting catechin (Patent Document 1). Examples of other reported components having endurance enhancing effects include hawthorn extract (Patent Document 2), ganoderma component (Patent Document 3), proanthocyanidins and lycopene (Patent Document 4). Examples of the component having anti-fatigue action include coenzyme Q10, a carnitine compound (Patent Document 5), a glutamine peptide (Patent Document 6), and the like.

  In addition, as components that can control exercise ability, for example, aging prevention by cystine and theanine (Patent Document 7), muscle atrophy suppression by fruit polyphenol (Patent Document 8), muscle protein degradation suppression by lycopene (Patent Document 9), carboxyl Inhibition of athletic ability decrease using an organic acid having two or more groups or a salt thereof as an active ingredient (Patent Document 10), an anti-fatigue agent using astaxanthin and / or its ester (Patent Document 11), a muscle atrophy inhibitor using proanthocyanidins, and An athletic performance improver (Patent Literature 12, Patent Literature 13) and the like are disclosed. However, at present, the effects on endurance, muscle strength, energy metabolism decrease and muscle atrophy associated with actual aging have not been studied.

Resveratrol is a polyphenol component contained in grapes and their processed wines, peanuts, etc., and has a rich dietary experience. Resveratrol exhibits actions such as anticancer action (Non-Patent Document 1) and anti-arteriosclerosis action (Non-Patent Document 2), and also reports a life extension action via a molecule called Sir (Non-Patent Document 3). Has been. It is also disclosed that it is useful in the prevention and treatment of hyperlipidemia (Patent Document 14) and the prevention or treatment of cerebral and age-related diseases (Patent Document 15).
On the other hand, red grape leaf extract has been traditionally known for use as a therapeutic agent for venous insufficiency for a long time. A method for improving blood circulation using red grape leaf extract (Patent Document 16) and a method for treating chronic venous insufficiency ( Patent document 17) is disclosed.

However, the effects of resveratrol and grape leaf extract on endurance and other athletic performance, fatigue, and on endurance and energy metabolism associated with aging have never been known. .

  The typical test examples and examples of the present invention are shown below.

Test Example 1 Resveratrol Endurance Improvement / Anti-Fatigue Effect Evaluation of resveratrol endurance improvement / anti-fatigue effect was performed as follows. Resveratrol manufactured by Cayman was used.

  Endurance improvement and anti-fatigue effects were evaluated by a method for measuring the limit swimming time of mice in a running water pool (reference: Am J Physiol Regul Integr Comp Physiol, Vol. 288, R708-R715, 2005). The experimental pool was used with a transparent acrylic pool (length 90 × width 45 × depth 45 cm) filled with water to a depth of 38 cm and maintained at 34 ° C. with a heater. The water flow was created using a pump (C-P60H, manufactured by Hitachi), and the flow rate was adjusted by connecting a water flow meter (Tokyo Flow Meter Laboratory) to the pump and opening and closing the valve. Moreover, the flow velocity was confirmed with a velocimeter (SV-101-25S, Sanko Precision Industry).

  As experimental animals, 5-week-old Balb / c male mice (Charles River) were preliminarily raised for 1 week in a constant breeding environment (23 ± 2 ° C, light period: 7 am to 7 pm). Acclimated. After that, for one week, training was performed three times a week to get used to swimming exercise (30 minutes of swimming exercise was performed on the first day for 30 minutes at a flow rate of 5 L / min, 3 days on the third day, and 6 L / min for 30 minutes on the third day). ). In the next week, with each individual fasted for 2 hours, limit swimming time at a flow rate of 7 L / min (the limit swimming time was defined as the time when rescued in a state where the face could not be exposed due to breathing). Measured once. The group was divided into two groups, the test food group and the control food group, with 8 animals per group so that there was no difference between the groups in the limit swimming time. Using the diet prepared with the composition shown in Table 1, the animals were reared for 10 weeks. During this time, limit swimming time measurement (7 L / min) and training (6 L / min, 30 minutes) were performed once a week. Table 2 shows the limit swimming time of mice at the 10th week of breeding.

  From Table 2, in the mice that received the test meal containing resveratrol, the marginal swimming time after 10 weeks of breeding was significantly extended compared to the control group, and resveratrol improved endurance, It can be seen that it has an anti-fatigue effect. Moreover, it turns out that it has a motor function improvement effect. From the above, resveratrol is useful as an endurance improver, anti-fatigue agent, and motor function improver.

Test Example 2 Endurance Improvement / Anti-fatigue Effect of Grape Leaf Extract Evaluation on the endurance improvement / anti-fatigue effect of the grape leaf extract and grape seed extract was performed as follows. In addition, the grape leaf extract used the red grape leaf dry extract of Ask Pharmaceutical Co., Ltd., and the grape seed extract used Grape Seed Extract (95%) of Organic Herb.
The same procedure as in Test Example 1 was performed except for the diet prepared with the formulation shown in Table 3. Table 4 shows the limit swimming time of mice in the 10th week of breeding.

  From Table 4, in the mice that received the test meal containing red grape leaf extract, the marginal swimming time after 10 weeks of breeding was significantly extended compared to the control diet group, and the grape leaf extract was endurance. It can be seen that it has an improving effect and an anti-fatigue effect. Moreover, it turns out that it has a motor function improvement effect. On the other hand, in the group that ingested the grape seed extract diet, the marginal swimming time tended to be extended as compared with the control diet group, but the extent of extension was small compared with the grape leaf extract diet group, which was significant. It was not a big difference. The grape leaf extract and grape seed extract both contain polyphenols and anthocyanins. From the results of this test, the composition of the components contained in the grape leaf extract is an endurance improver and anti-fatigue agent. Therefore, it is considered more useful as a motor function improver.

Test Example 3 Resveratrol Aging Inhibition Effect Resveratrol was evaluated for aging as follows. Resveratrol was manufactured by Organic Herb.

13 weeks old SAM-P1 male mice (aging-promoting model mice) and SAM-R1 male mice (usually aging mice) were preliminarily raised for 5 weeks in individual breeding, then acclimated to treadmill running, and the limit running time was measured did. Measurements were started after the mice were rested in a treadmill and accustomed to the environment. The belt speed starts at 10m / min, 10, 15m / min for 5 minutes each, 20m / min for 60 minutes, 22m / min for 60 minutes, 24m / min for 60 minutes, 26m / min for 60 minutes, and so on Was performed at a speed of 28 m / min. The time when the mouse could not run on the treadmill was defined as the limit running time, and the exercise endurance was evaluated. The SAM-R1 control group, the SAM-P1 control group, and the SAM-P1 resveratrol group were divided into groups (5 to 8 animals) so that there was no difference in the limit running time of each system.
It was reared for 10 weeks using the diet prepared with the formulation shown in Table 5. Each mouse was subjected to exercise for 30 minutes at 15 m / min three times a week.

  The limit running time of each group was measured after rearing for 8 weeks. Table 6 shows the mouse limit travel time at this time. In addition, after consumption for 9 weeks, oxygen consumption of each group was measured by breath analysis as energy metabolism at rest. For analysis, an 8 chamber chamber of the Oxymax system (Columbus) was used. After the mouse was placed in the chamber and allowed to rest for 6 hours, measurements were taken continuously for 2 minutes every 18 minutes for 24 hours. The average oxygen consumption for 24 hours is shown in Table 7. On the final day of the experiment, the mice were dissected and the gastrocnemius, soleus and plantar muscles were removed, and then the weight was measured to determine the total muscle weight. Table 8 shows the total muscle weight per body weight.

  From the results of Table 6, the limit running time of the SAM-P1 control group, which is an aging-promoting mouse, is significantly reduced compared to the SAM-R1 control group, which is usually an aging mouse, and the endurance decreases with aging. Moreover, the limit running time of the mouse | mouth which ingested the feed which mix | blended the resveratrol was significantly long with respect to the SAM-P1 control group, and it turns out that resveratrol has the endurance fall inhibitory effect by aging. Moreover, it turns out that it has a motor function improvement effect | action.

  From the results of Table 7, the oxygen consumption of the SAM-P1 control group, which is an aging-promoting model mouse, is significantly decreased compared to the SAM-R1 control group, which is a normal aging mouse, and energy metabolism decreases with age. However, the amount of oxygen consumed by mice ingesting a diet containing resveratrol was significantly higher than that of the SAM-P1 control group, indicating that resveratrol has an inhibitory effect on energy metabolism decline due to aging.

From the results in Table 8, the muscle weight in the body weight of the SAM-P1 control group, which is an aging-promoting model mouse, is significantly reduced compared to the SAM-R1 control group, which is usually an aging mouse. I understand that Moreover, it turns out that the muscle weight of the mouse | mouth which ingested the feed which mix | blended resveratrol was significantly larger than the SAM-P1 control group.
From the above, the resveratrol of the present invention is useful as an aging inhibitor, specifically, an endurance reduction inhibitor accompanying aging, a muscle atrophy inhibitor, and an energy metabolism reduction inhibitor.

Test Example 4 Resveratrol aging effect of muscular strength reduction due to aging Resveratrol was evaluated for muscular strength reduction due to aging as follows. Resveratrol was manufactured by Organic Herb.

  A 13-week-old SAM-P1 male mouse (an aging-promoting model mouse) and a SAM-R1 male mouse (usually an aging mouse) were preliminarily raised for 5 weeks in individual breeding, and then acclimated to running on a treadmill. Then, it divided into SAM-R1 control group, SAM-P1 control group, SAM-P1 exercise group, SAM-P1 resveratrol group / exercise (each group 5 animals). Using the diet prepared with the formulation shown in Table 9, it was raised for 13 weeks. Each mouse in the exercise group was subjected to exercise at 15 m / min for 30 minutes three times a week.

  The mice were subjected to dissection after 13 weeks of breeding, and the excised longus extensor muscles were placed in a Krebs solution at 37 ° C. (aeration conditions: 95% -oxygen, 5% -carbon dioxide) with a transducer (FORT100: World Precision Instruments, Inc.). )). Thereafter, electrical stimulation (0.5 ms, 140 Hz) was applied, and the maximum muscle strength was measured. Table 10 shows the measurement results of muscle strength.

From the results of Table 10, the maximum muscle strength of the long-knee extensor muscle of the SAM-P1 control group, which is an aging-promoting mouse, is significantly lower than that of the SAM-R1 control group, which is usually an aging mouse. However, the maximum muscular strength of mice ingesting a diet containing resveratrol is significantly higher than that of the SAM-P1 control group, and it can be seen that resveratrol has an inhibitory effect on muscular strength reduction due to aging.
From the above, the resveratrol of the present invention is useful as an aging inhibitor, specifically, a muscular strength decrease inhibitor accompanying aging.
