Objective: To investigate the effects of a 12-week resistance exercise program with an elastic band on electroencephalogram (EEG) patterns and cognitive function in elderly patients with mild cognitive impairment (MCI).

Design: Randomized controlled trial.

Setting: Community center.

Therapeutic effects of tai chi in patients with Parkinson's disease.

Objective. The purpose of the study was to investigate the effects of a 12-week program of therapeutic Tai Chi on the motor function and physical function of idiopathic Parkinson's disease patients (PDs). Methods.

Low-intensity treadmill exercise enhances fast recovery from bupivacaine-induced muscle injury in rats.

Background: Although bupivacaine has been used to study muscle degeneration and regeneration, the potential enhancement of muscle injury by exercise has not been well examined. The purpose of this study was to determine whether low-intensity treadmill exercise enhances fast recovery from bupivacaine-induced muscle injury and to examine concomitant changes in heat-shock protein 70 (HSP70) expression during regeneration process.

Methods: In this study, Sprague-Dawley rats were randomly divided into the following four groups: the control group (CON), the sham group (SHAM), the injury group (INJ), and the injury and exercise group (EX) ( = 14 in each group).

The impact of duration of one bout treadmill exercise on cell proliferation and central fatigue in rats.

The purpose of this study was to investigate the impact of the duration-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 exercise 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° inclination.

Treadmill exercise alleviates short-term memory impairment in 6-hydroxydopamine-induced Parkinson's rats.

Progressive loss of dopaminergic neurons in substantia nigra is a key pathogenesis of Parkinson's disease. In the present study, we investigated the effects of treadmill exercise on short-term memory, apoptotic dopaminergic neuronal cell death and fiber loss in the nigrostriatum, and cell proliferation in the hippocampal dentate gyrus of Parkinson's rats. Parkinson's rats were made by injection of 6-hydroxydopamine (6-OHDA) into the striatum using stereotaxic instrument.

Physical activity and body mass index and their associations with the development of type 2 diabetes in korean men.

The authors examined the independent and combined associations of physical activity and obesity with incident type 2 diabetes among 675,496 Korean men from the database of the National Health Insurance Corporation. During an average follow-up of 7.5 years (1996-2005), 52,995 men developed type 2 diabetes.

Effects of postnatal treadmill exercise on apoptotic neuronal cell death and cell proliferation of maternal-separated rat pups.

Early adverse experiences resulting from maternal separation may lead to neuronal cell death and they can eventually cause memory impairment. In this study, we investigated the effects of postnatal treadmill exercise on the long-term memory capability, spatial learning ability, and depressive state, on the 5-hydroxytryptamine (5-HT, serotonin) synthesis and tryptophan hydroxylase (TPH) expression in the dorsal raphe nuclei, and on the apoptosis and cell proliferation in the hippocampal dentate gyrus of rat pups following maternal separation. The rat pups in the maternal separation groups were separated from their respective mothers on the postnatal day 14.

The effects of a walking exercise program on fall-related fitness, bone metabolism, and fall-related psychological factors in elderly women.

The purpose of this study was to determine the effects of a 3-month walking exercise program with ankle weights on fall-related fitness, bone metabolism, and fall-related psychological factors. Fall-related fitness was determined from strength, balance, agility, aerobic endurance, muscle mass, and fat mass measures. Bone metabolism was measured using bone density, hormones, and biochemical markers.

Aerobic exercise training-induced decrease in plasma visfatin and insulin resistance in obese female adolescents.

The purpose of this study was to assess differences in the levels of plasma visfatin among female adolescents and changes in plasma visfatin and insulin resistance in obese female adolescents after 12 wk of aerobic exercise training. Twenty normal-weight female students (body-mass index [BMI] < 22.9 kg/m² and body fat ≤ 29.

Salivary cortisol and immunoglobulin A responses during golf competition vs. practice in elite male and female junior golfers.

The purpose of this study was to investigate the stress and immune responses to a competition in elite male and female junior golfers. Six male (16.2 +/- 1.

Effects of exercise on cyclooxygenase-2 expression and nuclear factor-kappaB DNA binding in human peripheral blood mononuclear cells.

There are multiple lines of compelling evidence supporting the beneficial effect of exercise on the prevention and/or improvement of certain chronic diseases. However, exhaustive or intense exercise causes oxygen free radical generation and oxidative stress, which can lead to injuries and chronic fatigue as well as inflammation. Abnormal upregulation of cyclooxygenase-2 (COX-2), a rate-limiting enzyme in prostaglandin biosynthesis, has been implicated in many inflammation-associated chronic disorders.

Exercise training improves the antioxidant enzyme activity with no changes of telomere length.

The purpose of this study was to determine the changes of both oxidant and antioxidant levels with exercise training in obese middle-aged women. The association between telomere length and oxidative stress with exercise was also examined. Sixteen obese middle-aged women participated in this study.
