Background: The purpose of this study is to measure the amount of influence of taping and a whole body balance upon muscle strength, endurance, and flexibility. Experiments were conducted by two different groups, specially designed for this study. The choice of exercise methods for each group depends on its own idiosyncratic characteristics (or Each group employs its own idiosyncratic exercise method). Methods: The first group, with taping applied, undertook exercises three times a week; second group just took exercises three times a week. These experiments show the following outcomes. Results: The first group showed a considerable amount of difference in terms of muscle strength, endurance, and flexibility. Second group also showed similar outcome. Both the first group and the second group revealed a considerable difference. But the first group showed a bigger difference than the second group. Conclusion: Thus, the result of these experiments strongly indicates that exercise, with taping applied, turns out the most effective in promoting muscle strength, endurance, and flexibility.

In general, research in isokinetic exercise has focussed on studies of peak torque. However, peak torque is not always sufficient to assess the real amount of motion or to determine endurance. In this study, the subjects were 54 healthy students who performed continuous maximal isokinetic knee flexion and extension until their total work per time reached 50% of their maximal total work. Isokinetic curves were then plotted. Total work sums, exercise durations in seconds, and the numbers of repetitions were compared with reference to subject gender, angular velocity and muscle group. The relationship between total work sum, duration and number of repetition and thigh circumference plus leg length was computed. In addition, the characteristics of total work per second and total work per time were calculated. Results showed the total work sums differed greatly from muscle group to muscle group and with different angular velocities. The duration in seconds and the numbers of repetition differed only at higher angular velocity. Males achieved higher levels in every category except for some duration in seconds and some numbers of repetitions. Thigh circumference and leg length were deciding fators in every case, but duration in seconds and number of repetitions were not. These results suggest that measures of endurance should be included along with measures of total work when isokinetic studies are done. Measures of endurance in seconds are more accurate when isokinetic exercise is performed at lower angular velocities and numbers of repetitions at higher angular velocities.
While athletic abilities such as speed, endurance and recovery are important in the horse, genes related to these abilities have not been extensively investigated. Here, we characterized the horse peroxisome proliferator-activated receptor delta ($PPAR{\delta}$) gene and analyzed the expression of $PPAR{\delta}$ during exercise. $PPAR{\delta}$ is a known regulator of ${\beta}$-oxidation, muscle fiber transformation, and running endurance. Through evolutionary analysis using the synonymous and non-synonymous mutation ratio, it was revealed that positive selection occurred in the horse $PPAR{\delta}$ gene. Two important domains related to nuclear hormone receptors, C4 zinc finger and ligand binding domain, were also found to be conserved well in horse $PPAR{\delta}$. Horse $PPAR{\delta}$ was expressed ubiquitously in many tissues, but the expression level was various depending on the tissues. In the skeletal muscle, $PPAR{\delta}$ increased about 2.5 folds after 30 min of exercise. Unlike in muscle, the increase of $PPAR{\delta}$ expression was observed at 60 min but not 30 min of exercise in leukocytes. This finding might be useful for testing the endurance of horse using blood samples. Conclusively, the horse $PPAR{\delta}$ gene is evolutionarily conserved well and can be used as a biomarker of endurance in horse.
The purpose of this study was to analyze the effects of intake of aronia, montmorency, and Prunus mume on 10 km endurance exercise by investigating changes in blood lactate, ammonia, creatine kinase (CK), and lactate dehydrogenase (LDH), and eventually to recommend them as ergogenic aids, which are effective for recovering from exercise fatigue and muscle damage. The subjects were divided into a P. mume intake group, an aronia intake group, a montmorency intake group, and a control group. Blood samples were taken from the brachial vein at rest, and at 0, 30 min, and 24 hr after running to measure recovery status. All data were analyzed by a two-way repeated-measures analysis of variance using SPSS. The results are summarized as follows: The changes in blood ammonia and LDH concentration following 10 km of running were not significantly different among the groups. However, lactate and CK recovery ratio increased significantly in the aronia and montmorency groups compared to those in the P. mume and control groups. In particular, CK concentration was significantly different in the montmorency group compared to that in the other groups. These results suggest that the effects of aronia and montmorency are associated with improved recovery from muscle fatigue and damage induced by highly intensive exercise, endurance exercise, or overtraining. In particular, montmorency is recommended as an ergogenic aid to inhibit muscle pain resulting from high-intensity endurance exercise.
The purpose of this study is to investigate the effects of arabinoxylan rice bran and endurance exercise training on TLR4 mediated protein expression in LPS-treated rats. The results showed that TLR4 as an important protein in the inflammatory response against lipopolysaccharide was shown to be significantly lower in both arabinoxylan supplement with exercise group and exercise group, thus the arabinoxylan rice bran had a higher inhibitory activity than arabinoxylan supplement group. However, $NF-{\kappa}B$ and MyD88 protein expression was not changed in arabinoxylan supplement with exercise training group, whereas $NF-{\kappa}B$ significantly decreased in 4 weeks of exercise training group. These results suggest that the supplement of arabinoxylan rice bran with exercise is likely to contribute to inflammation response and the arabinoxylan rice bran can be used as a possible safe alternative to the immunotherapeutic intervention.
The purpose of this study is to determine the effects of the aerobic exercise type on macronutrient self-selection. Male Sprague-Dawley rats were placed on a macronutrient self-selection diet for 4 weeks. For this purpose, mixed feeds were prescribed for the rats while they were forced to swim and run for 4 weeks. Animals were either swimming exercise or treadmill running exercised at 20m/min(60min/day). Cumulative daily energy and macronutrient intake were determined during this period. The running exercise group gained weight much more than the control group, while the swimming exercise group lost weight less than the control group. Such findings suggests that the former group took more feed. On the other hand, the dietary efficiency of the control group was higher, which implies that no physical exercise would result in a higher dietary efficiency. And there was significant difference of total dietary and calorie intakes among the three groups, Although insignificant in statistical means, it was found that the running group took feed most, which is attributable to the homeostasis requiring the supplementation of the calorie lost by exercise. Also, the running exercise group took the protein and carbohydrate most. while the control group took fat most. The decrease of fat intake by the running exercise group suggests the possibility that the in-body enzymes should adapt themselves to the changing in-body condition caused by the endurance exercise. In contrast, it is conceived that the more intake of the carbohydrate may be attributable to the need of supplementing the nutrient lost by the endurance exercise. As discussed above, the endurance exercise group took carbohydrate and protein and less fat than control group. In particular, it was found that the amount of feed intakes was affected much by types, intensity and duration of the exercises. All in all, such findings would apply to human beings. Now can increase the intakes of carbohydrate and decrease the intake of fat through an effective running exercise program and thereby, change our dietary patterns to the benefit of our body and simultaneously, prevent and adult\\`s diseases by decreasing the in % body fat level.(Korean J Nutrition 33(8) : 794-801, 2000)

The purpose of this study was to identify cervical stabilized exercise and joint mobilization, the difference between them, and the maximum muscle strength and static muscle endurance of each group after the enforcement to general people. Cervical joint mobilization group refers to interarticular exercise (traction, pressure, glide) using with Kaltenborn technique. 3 classes were divided into 20 people each, cervical joint mobilization and stabilized exercise, and the comparison groups were randomized for the study. Both cervical stabilized exercise and joint mobilization increased maximum muscle strength and static muscle endurance. Patients should be able improve muscle stabilization and deep cervical muscle by using joint mobilization when the patient is unable to exercise on their own.

The objective of this study was to analyze the concurrent treatment effects of ursolic acid (UA) and low-intensity treadmill exercise and to confirm the effectiveness of UA as an exercise mimetic to safely improve muscle atrophy-related diseases using Sprague-Dawley (SD) rats with skeletal muscle atrophy. Significant muscle atrophy was induced in male SD rats through hind limb immobilization using casting for 10 days. The muscle atrophy-induced SD rats were group into four: SED, sedentary; UA, daily intraperitoneal UA injection, 5 mg/kg; EX, low-intensity (10-12 m/min, $0^{\circ}$ grade) treadmill exercise; and UEX, daily intraperitoneal UA injection, 5 mg/kg, and low-intensity (10-12 m/min, $0^{\circ}$ grade) treadmill exercise. After 8 weeks of treatment, endurance capacity was analyzed using a treadmill, and tissues were extracted for analysis of visceral fat mass, body weight, muscle mass, expression of muscle atrophy- and hypertrophy-related genes, and endurance capacity. Although the effects of body weight gain control, muscle mass increase, and endurance capacity improvement were inadequate in the UA group, significant results were confirmed in the UEX group. The UEX group had significantly reduced body weight and visceral fat, significantly improved mass of tibialis anterior and gastrocnemius muscles, and significantly decreased atrophy-related gene expression of MuRF1 and atrogin-1, but did not have significant change in hypertrophy-related gene expression of Akt and mTOR. The endurance capacity was significantly improved in the EX and UEX groups. These data suggest that concurrent treatment with low-intensity exercise and UA is effective for atrophy-related physical dysfunctions.
Exercise has been shown to positively influence quality of life for elderly men with a wide variety of medical illnesses. Tai chi exercise, a slow and graceful form of exercise and meditation, has especially been offered as the ideal exercise for elderly men with diverse conditions, such as people suffering from chronic heart failure or breast cancer survivors. In one recent study, Tai Chi was found to improve exercise capacity, sleep stability, and quality of life in heart failure patients including elderly men. The purpose of the study was to examine the effects of 16 weeks of Tai Chi exercise (3 times/week, 60 min/trial, 40-50% HRR) on physical and physiological changes. Sixty four healthy volunteers without any particular disease between the ages of 65 and 79 years participated in the study. The results were as follows; Significant changes of cardiac endurance, strength, muscle endurance, flexibility and balance were observed following 16 weeks of Tai Chi exercise (p<0.05). In addition, significant changes of diastolic blood pressure, body fat and fat-free mass were observed following 16 weeks of Tai Chi exercise (p<0.05). These findings suggest that a brief period of Tai Chi exercise is beneficial, particularly to elderly men. It is especially beneficial for body composition, and physical fitness factors such as cardiopulmonary endurance, muscle endurance, flexibility, and balance. Further study is needed in this area for specific disease patients.
The effects of taurine, carnitine or glutamine supplementation on endurance exercise performance along with related fatigue factors were evaluated in male college students in the Department of Physical Education, who's maximal oxygen consumption rates (VO$_2$max) were equivalent to those of endurance athletes. Twenty four subjects were randomly divided into 4 groups (n=6), and given placebo, taurine (4 g/day), carnitine (4 g/day), or glutamine (4 g/day) tablets for 2 weeks. Subjects could run 6.9 min or 9.0 min longer until exhausted on a treadmill at the intensity of 75% VO$_2$max following taurine or camitine supplementation for 2 weeks, respectively, compared to the value measured prior to each supplementation. Glutamine or placebo supplementation did not improve the endurance exercise performance based on the running time until exhausted on a treadmill. Serum lactate concentrations measured 1 hr after the initiation of the endurance exercise, as well as at all-out state tended to be decreased by taurine, carnitine, or glutamine supplementation, and were significantly lowered (43% decrease) by carnitine supplementation (p < 0.05). Taurine supplementation significantly reduced the serum inorganic phosphorus concentration measured at all-out state (14% decrease, p < 0.05), while carnitine supplementation significantly lowered the resting state serum inorganic phosphorus level (20% decrease, p < 0.05). Taurine (32% reduction) or carnitine (23% reduction) supplementation significantly decreased serum ammonia concentration measured at all-out state (p < 0.05). From these results, 4 g/day of taurine or carnitine supplementation appears to improve the endurance exercise performance and related human fatigue factors.
