Abstract
INTRODUCTION Exploring the potential of exercise in the rehabilitation process of patients with Parkinson's (PD) may be an interesting treatment perspective. Exercise-induced responses derived from neurotrophic elements appear to ameliorate the decline in neurodegeneration. Despite this understanding, the literature needs to be updated. AREAS COVERED Our review focuses on: a) the key mechanisms of exercise on PD, highlighting mainly the responses related to neuroplasticity; b) the effects induced by different traditional types of exercise, also highlighting the effects of complementary therapies related to movement; c) the volume of exercise required to support efficient results are explored in the context of PD. Additionally, the proposition of new clinical application strategies in the context of PD will also be determined. EXPERT OPINION It is suggested that different intensities of aerobic exercise be explored for the treatment of PD. The results associated with high intensity seem promising for performance, physiological and clinical parameters, such as BDNF production and cognition. On the other hand, the diversification of tasks and repetition of motor gestures appear as consistent arguments to exercise prescription. Finally, for future investigations, the neuromodulation strategy in association with aerobic exercise appears as a potential inducer of benefits on gait and cognitive function.

Abstract
Parkinson's disease (PD) is manifested by progressive motor, autonomic, and cognitive disturbances. Dopamine (DA) synthesizing neurons in the substantia nigra (SN) degenerate, causing a decline in DA level in the striatum that leads to the characteristic movement disorders. A disease-modifying therapy to arrest PD progression remains unattainable with current pharmacotherapies, most of which cause severe side effects and lose their efficacy with time. For this reason, there is a need to seek new therapies supporting the pharmacological treatment of PD. Motor therapy is recommended for pharmacologically treated PD patients as it alleviates the symptoms. Molecular mechanisms behind the beneficial effects of motor therapy are unknown, nor is it known whether such therapy may be neuroprotective in PD patients. Due to obvious limitations, human studies are unlikely to answer these questions; therefore, the use of animal models of PD seems indispensable. Motor therapy in animal models of PD characterized by the loss of dopaminergic neurons has neuroprotective and neuroregenerative effects, and the completeness of neuronal protection may depend on (i) degree of neuronal loss, (ii) duration and intensity of exercise, and (iii) time elapsed between insult and commencing of training. As the physical activity is neuroprotective for dopaminergic neurons, the question arises what is the mechanism of this protective action. A current hypothesis assumes a central role of neurotrophic factors in the neuroprotection of dopaminergic neurons, even though it is still not clear whether increased DA level in the nigrostriatal axis results from neurogenesis of dopaminergic neurons in the SN, recovery of the phenotype of dopaminergic neurons, increased sprouting of the residual dopaminergic axons in the striatum, or generation of local striatal neurons from inhibitory interneurons. In the present review, we discuss studies describing the influence of physical exercise on the PD-like changes manifested in animal models of the disease and focus our interest on the current state of knowledge on the mechanism of neuroprotection induced by physical activity as a supportive therapy in PD.

J Strength Cond Res 31(3): 582-594, 2017-The aim of the present study was the monitoring of the redox status of runners participating in a mountain ultramarathon race of 103 km. Blood samples from 12 runners were collected prerace and 24, 48, and 72 hours postrace. The samples were analyzed by using conventional oxidative stress markers, such as protein carbonyls (CARB), thiobarbituric acid reactive substances (TBARS), total antioxidant capacity (TAC) in plasma, as well as glutathione (GSH) levels and catalase (CAT) activity in erythrocytes. In addition, 2 novel markers, the static oxidation-reduction potential marker (sORP) and the capacity oxidation-reduction potential (cORP), were measured in plasma. The results showed significant increase in sORP levels and significant decrease in cORP and GSH levels postrace compared with prerace. The other markers did not exhibit significant changes postrace compared with prerace. Furthermore, an interindividual analysis showed that in all athletes but one sORP was increased, whereas cORP was decreased. Moreover, GSH levels were decreased in all athletes at least at 2 time points postrace compared with prerace. The other markers exhibited great variations between different athletes. In conclusion, ORP and GSH markers suggested that oxidative stress has existed even 3 days post ultramarathon race. The practical applications from these results would be that the most effective markers for short-term monitoring of ultramarathon mountain race-induced oxidative stress were sORP, cORP, and GSH. Also, administration of supplements enhancing especially GSH is recommended during ultramarathon mountain races to prevent manifestation of pathological conditions.

Abstract
Abstract Introduction: Parkinson’s disease (PD) is characterized by nigrostriatal degeneration, with dopaminergic depletion, and inflammatory and oxidative changes in the brain, leading to movement and coordination disorders. Recent studies have shown that treadmill training can be beneficial for these patients, but there is little evidence assessing the related blood parameters, such as oxidative stress and neurotrophin levels. Objective: Assess the influence of treadmill training for patients with Parkinson’s on gait, balance, Brain-Derived Neurotrophic Factor (BDNF) and reduced glutathione. Methods: Twenty-two patients with PD (Hoehn and Yahr II and III), older than 40 years, were randomly allocated to two groups: CG (n = 12) - drug treatment and IG (n = 10) - treadmill. Assessments related to functional capacity (quality of life, static and dynamic analysis of gait) and blood parameters such as GSH and BDNF were conducted before and after the eight-week intervention. Results: The demographic data of the groups were homogeneous in terms of age, sex, height, weight, time since disease onset, mini mental examination and the geriatric depression scale. Significant intergroup differences were found for the mental component summary, surface variation, latero-lateral oscillation, antero-posterior oscillation and mean velocity in the post-intervention period. The IG exhibited a strong association between BDNF and GSH, with statistically significant values. Conclusion: It was concluded that controlled treadmill walking improves static balance, quality of life and plasma BDNF and GSH levels in patients with PD.

Abstract
The pathophysiologies of neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), and Alzheimer's disease (AD), are far from being fully explained. Oxidative stress (OS) has been proposed as one factor that plays a potential role in the pathogenesis of neurodegenerative disorders. Clinical and preclinical studies indicate that neurodegenerative diseases are characterized by higher levels of OS biomarkers and by lower levels of antioxidant defense biomarkers in the brain and peripheral tissues. In this article, we review the current knowledge regarding the involvement of OS in neurodegenerative diseases, based on clinical trials and animal studies. In addition, we analyze the effects of the drug-induced modulation of oxidative balance, and we explore pharmacotherapeutic strategies for OS reduction.

Abstract
Parkinson's disease (PD) is one of the most prevalent neurodegenerative diseases in the world. The degeneration of dopaminergic neurons in the substantia nigra and chronic inflammation impair specific brain areas, which in turn result in lesser motor control, behavioral changes and cognitive decline. Nowadays, drug-treatments are the foremost approaches in treating PD. However, exercise has been shown to have powerful effects on PD, based on several neurobiological mechanisms. These effects may decrease the risk of developing PD by 33%. However, these mechanisms are unclear and little explored. Among several mechanisms, we propose two specific hypotheses: 1. Physical exercise reduces chronic oxidative stress and stimulates mitochondria biogenesis and up-regulation of authophagy in PD patients. Moreover, antioxidant enzymes (e.g. superoxide dismutase) become more active and effective in response to physical exercise. 2. Exercise stimulates neurotransmitter (e.g. dopamine) and trophic factors (BDNF, GDNF, FGF-2, IGF-1, among others) synthesis. These neurochemical phenomena promote neuroplasticity, which, in turn, decreases neural apoptosis and may delay the neurodegeneration process, preventing or decreasing PD development and symptoms, respectively.

Abstract
PURPOSE This study aimed to explore plasma antioxidant status in de novo Chinese Parkinson's disease (PD) patients and investigate its relationship with specific motor features of PD. PATIENTS AND METHODS Sixty-four de novo Chinese PD patients and 40 age- and sex-matched healthy controls were recruited. Each motor feature of PD patients was assessed by unified Parkinson's disease rating scale. Plasma antioxidant status, including plasma level of glutathione (GSH) and plasma activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), was detected using enzyme-linked immunosorbent assay. The relationship between the plasma antioxidant status and motor features of PD was evaluated by Spearman's coefficient. RESULTS Plasma GSH level and plasma activities of GSH-Px, CAT and SOD of PD patients were lower than those of healthy controls. Moreover, the declining activity of plasma CAT was related with the increasing mean postural instability and gait disorder (PIGD) score and growing age. In contrast, the severity of tremor was positively correlated with plasma SOD activity. CONCLUSION Our study demonstrates that the plasma antioxidant status is impaired in de novo Chinese PD patients. The complex relationship between the plasma antioxidant status and different motor features indicates that the antioxidant mechanisms underlying tremor and PIGD of PD may be different.

Abstract
Exercise induces oxidative stress, which may activate adaptive antioxidant responses. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays an important role in the defense of oxidative stress by regulating the expression of antioxidant enzymes, gamma-glutamylcysteine ligase (γGCL) and heme oxygenase-1 (HO-1). We investigated whether treadmill exercise protects dopaminergic neurons by regulating the Nrf2 antioxidant system in a 1-methyl-4-phenylpyridine (MPP(+))-induced parkinsonian rat model. We found that MPP(+) induced early decreases in total glutathione level and Nrf2/γGCLC (catalytic subunit of γGCL) expression, but late upregulation of HO-1 expression in association with loss of nigral dopaminergic neurons and downregulation of tyrosine hydroxylase and dopamine transporter expression in the striatum. Treadmill exercise for 4weeks induced upregulation of Nrf2 and γGCLC expression, and also prevented the MPP(+)-induced downregulation of Nrf2/γGCLC/glutathione, HO-1 upregulation, and nigrostriatal dopaminergic neurodegeneration. Moreover, the protective effect of exercise was blocked by the knockdown of Nrf2 using a lentivirus-carried shNrf2 delivery system. These results demonstrate an essential role of Nrf2 in the exercise-mediated protective effect that exercise enhances the nigrostriatal Nrf2 antioxidant defense capacity to protect dopaminergic neurons against the MPP(+)-induced toxicity.

Abstract
BACKGROUND Individuals with Parkinson's disease (PD) have decreased glutathione levels and elevated homocysteine levels. These substances are considered markers of health, and an inverse relationship has been suggested through the transsulfuration pathway. This experiment tested the effects of exercise and B vitamin supplementation on homocysteine and glutathione levels, and if a relationship was present between these two markers in those with PD. Secondary aims included examining the impact of the interventions on aerobic efficiency and strength. METHODS Thirty-six subjects were randomly assigned to 4 groups. The Vit group received vitamins B(6), B(12) and folic acid daily for 6 weeks. The Ex group received aerobic and strength training twice weekly for 6 weeks. The Vit + Ex group received both interventions. A control group received no intervention. Subjects were tested prior to and after intervention on the following measures: glutathione and homocysteine levels, strength measures and oxygen consumption. RESULTS Subjects who received 6 weeks of B vitamin supplementation had lowered homocysteine levels. Subjects who received 6 weeks of exercise training had increased glutathione levels, strength and aerobic capacity. The combination of vitamin and exercise did not yield greater changes than the separate intervention. The control subjects did not change on any measures. CONCLUSION Positive results were realized with each intervention; however, the expected relationship between glutathione and homocysteine was not found in this sample of subjects with PD. Homocysteine and glutathione levels can be improved independently in individuals with PD with exercise or vitamins B(6), B(12) and folic acid supplementation.
