The purpose of this study was to investigate the impact of the dura-tion-dependence of the one bout treadmill exercise on cell proliferation, stress, and central fatigue in rats. The animals were randomly divided into five groups: the non-exercise group, 1-h exercise group, 2-h exer-cise group, 4-h exercise group, and 6-h exercise group. The exercise load consisted of running at speed of 13 meters/min with the 0° inclina-tion. Cell proliferation in the hippocampal dentate gyrus was increased in response to one bout moderate treadmill exercise in all exercise groups. But there was no statistical significance between the exercise duration and cell proliferation. The optical density of glucocorticoid (GR)-positive cells in the hippocampal dentate gyrus was not changed by treadmill exercise at any exercise duration. Expressions of serotonin (5-hydroxytryptamine, 5-HT) and tryptophan hyroxylase (TPH) were in-creased by treadmill exercise only at 6 h duration. It seemed like that there was no additional benefits on cell proliferation over 2 h exercise due to stressful factors with over exercise dose, and there was no change of GR expression due to early assessment point of time. It can be sug-gested that the one-bout of moderate treadmill exercise increased cell proliferation, but treadmill exercise prolonged to 6 h induced central fa- tigue in rats.

Objectives The purpose of this study was to analyze the effect of silver dance exercise on the levels of antioxidant enzymes in women aged 65 and older. Methods The study participants were divided into two groups: a 6-month group and a 12-month group of women aged 65 and older. The silver dance exercise program was conducted for 60 minutes per day, three times a week, for 12 months. Blood variables analyzed included total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP), and superoxide dismutase 2 (SOD2). Results The results of the study showed that the 12-month exercise group exhibited significant increases in HDL-C and SOD2 concentrations compared to before the exercise program (p<.05), indicating the effectiveness of the exercise. Conclusions Therefore, exercise programs aimed at anti-inflammatory and antioxidant effects in the elderly women are considered effective when considering long-term exercise duration.

Attention-deficit hyperactivity disorder (ADHD) is a common neurobe-havioral disorder, and its symptoms are hyperactivity and deficits in learning and memory. Physical exercise increases dopamine synthesis and neuronal activity in various brain regions. In the present study, we investigate the duration-dependence of the treadmill exercise on hyper-activity in relation with dopamine expression in ADHD. Spontaneously hypertensive rats were used for the ADHD rats and Wistar-Kyoto rats were used for the control rats. The rats in the exercise groups were forced to run on a treadmill for 10 min, 30 min, and 60 min once daily for 28 consecutive days. For this experiment, open field test and immuno-histochemistry for tyrosine hydroxylase were conducted. The present results revealed that ADHD rats showed hyperactivity, and tyrosine hy-droxylase expression in the striatum and substantia nigra were de-creased in ADHD rats. Treadmill exercise alleviated hyperactivity and also increased TH expression in ADHD rats. Treadmill exercise for 30 min per day showed most potent suppressing effect on hyperactivity, and this dose of treadmill exercise also most potently inhibited tyrosine hydroxylase expression. The present study suggests that treadmill exer-cise for 30 min once a day is the most effective therapeutic intervention for ADHD patients.

[PURPOSE] The purpose of this study was to examine the effects of muscle contraction speed on number of repetitions, exercise duration and muscle activation during push-up exercise in men. [METHODS] The study employed a randomized, counter-balanced crossover design with two testing sessions that were 3 months apart. Twelve, healthy, male collegiate students were asked to perform two exercises separately, normal-speed push-up (ECC: 1-s, CON: 1-s) and speedy-push-up (maximum speed), until repetition failure of volitional contraction. Outcomes were number of repetitions, exercise duration and muscle activation of the pectoralis major measured through surface electromyography (sEMG) during push-up exercises. The sEMG data were normalized to maximal voluntary isometric contraction (MVIC) and expressed as a percentage (%MVIC) in both ECC phase and CON phase. [RESULTS] Number of repetitions (t=-5.352, p<.001), exercise duration (t=-5.837, p<.001) and muscle activity (t=-4.525, p=.023) were significantly different between two exercise conditions. [CONCLUSIONS] Normal-speed push-up exercise increased exercise duration and muscular activity while, and speedy push-up exercise increased number of repetitions. Further studies are warranted to elucidate associations between muscle adaptation stimulus and muscle contraction speed.

[PURPOSE] The purpose of this study was to investigate effects of wearing compression stockings on number of repetitions, heart rate, exercise duration and iEMG. [METHODS] A total of 7 male students(22.0±2.8 yr; 174.0±5.8 cm; 75.2±11.0kg) who were free of lower extremity injury participated in this study. One and 10 RM of squats were measured. Five sets of 10 RM squats were performed with and without wearing compression stockings with resting intervals of 2 minutes between sets. Surface electrodes were placed over the rectus femoris and gastrocnemius muscles to measure muscle activation via iEMG. Paired t-tests and repeated ANOVA were conducted to determine differences between groups with statistical significance at p<.05. [RESULTS] The compression stocking significantly increased numbers of repetitions during the first 3 sets: 2.4(24%), 1.2(13.6%), and 1.3(16.7%), respectively. Significant differences were found between groups for the set 1-3(p<.01, p<.05, p<.05). However, there was no significant difference between groups in number s of repetitions during the set 4 and 5. Similarly, no differences were found in both groups during any of sets for the other variables: heart rate, exercise duration, and iEMG. [CONCLUSION] The compression stocking demonstrated an increase in number of repetitions, but had no changes in heart rate, exercise duration, and iEMG, which is related to efficiency of squat exercise.

[PURPOSE] The purpose of this study was to compare metabolic variables during exercise and recovery between mid and low intensity exercise in college students. [METHODS] Eight healthy university students were participated in two trials: (1) mid intensity exercise(60%VO2R, 45min; MI), and (2) low intensity exercise(40%VO2R, 60min; LI) in same energy expenditure condition on a treadmill exercise. [RESULTS] During the exercise, VO2 and exercise expenditure(EE) were significantly higher at MI than at LI (p=.000, p=.000), but no significant difference of exercise time was found. Respiratory exchanged ratio(RER) was significantly higher at MI than at LI(p=010), and was significantly higher in exercise 15min than in exercise 30 and 45min(p=000). Fat oxidation rate(FOR) and Fat oxidation (g/min, FO) were significantly lower at MI than at LI(p=.022, p=.034), and were significantly higher at 15min than exercise at 30 and 45min(p=000, p=.000), respectively. During the recovery, VO2 and EE were significantly higher at MI than at LI(p=.000, p=.000), and were significantly higher after 30min than after 15min of recovery(p=.000, p=.000), respectively. RER was not significantly different between MI and LI, but it was significantly lower after 45min than 15min recovery(p=.000). FOR and FO were not significant difference between MI and LI, but it was significantly higher after 30min than 15min recovery(p=.000, p=.000), respectively. [CONCLUSIONS] These finding suggest that the moderate exercise can contribute to greater exercise and recovery-induced fat oxidation and energy expenditure compared with a lower intensity continuous exercise.

BACKGROUND/OBJECTIVES: Energy production and the rebuilding and repair of muscle tissue by physical activity require folate and vitamin $B_{12}$ as a cofactor. Thus, this study investigated the effects of regular moderate exercise training and durations of acute aerobic exercise on plasma folate and vitamin $B_{12}$ concentrations in moderate exercise trained rats. MATERIALS/METHODS: Fifty rats underwent non-exercise training (NT, n = 25) and regular exercise training (ET, n = 25) for 5 weeks. The ET group performed moderate exercise on a treadmill for 30 min/day, 5 days/week. At the end of week 5, each group was subdivided into 4 groups: non-exercise and 3 exercise groups. The non-exercise group (E0) was sacrificed without exercising and the 3 exercise groups were sacrificed immediately after exercising on a treadmill for 0.5 h (E0.5), 1 h (E1), and 2 h (E2). Blood samples were collected and plasma folate and vitamin $B_{12}$ were analyzed. RESULTS: After exercise training, plasma folate level was significantly lower and vitamin $B_{12}$ concentration was significantly higher in the ET group compared with the NT group (P < 0.05). No significant associations were observed between plasma folate and vitamin $B_{12}$ concentrations. In both the NT and ET groups, plasma folate and vitamin $B_{12}$ were not significantly changed by increasing duration of aerobic exercise. Plasma folate concentration of E0.5 was significantly lower in the ET group compared with that in the NT group. Significantly higher vitamin $B_{12}$ concentrations were observed in the E0 and E0.5 groups of the ET group compared to those of the NT group. CONCLUSION: Regular moderate exercise training decreased plasma folate and increased plasma vitamin $B_{12}$ levels. However, no significant changes in plasma folate and vitamin $B_{12}$ concentrations were observed by increasing duration of acute aerobic exercise.
