“…These findings were in agreement with several previous studies (Goon et al, 2009;Huang et al, 2014;Onur et al, 2011;Wadiah et al, 2015). Huang et al (2014) reported that there was no significant change in GPx level at week 8 but there was a significant increase in GPx activity at week 12.…”

“…Performing higher physical activity or aerobic exercise alone has been proven to increase cardiovascular fitness (Kemmler et al, 2004;Suter et al, 1994) and improve lipid profile (Isler et al, 2001;Kannan et al, 2014). Performing exercise can also improve antioxidant adaptation (Goon et al, 2009;Onur et al, 2011) and reduce oxidative damage markers (Goon et al, 2009). In order to transform exercise into a top priority, the exercise chosen should be enjoyable and something that can be maintained so that it can be turned into a healthy lifestyle later (American College of Sports Medicine, 2009;Lavie, 2007).…”

Abstract:Problem Statement: Sedentary lifestyle predispose an individual to a number of chronic disease. Adopting a physically healthy lifestyle along with a consumption of nutritional supplementation is a strategy towards improving health related quality of life.Purpose: We aimed to investigate the combined effects of oat bran consumption and jogging exercise on aerobic capacity, lipid profile and antioxidant status in young sedentary males. Methods: Forty seven sedentary male university students with mean age 20.9 ± 1.7 years were recruited. They were randomly assigned to sedentary control (C), oat bran supplementation alone (O), exercise alone (J) and combined oat bran and exercise (OJ) groups. The participants in O and OJ groups consumed 18 g of oat bran powder which contains 3.6 g of β-glucan daily for 8 weeks. The participants in J and OJ groups performed jogging exercise with moderate intensity, i.e. 55% to 70% of their age-predicted HR max , 30 min per day, 3 days per week for 8 weeks. Participants' body composition, predicted maximal oxygen consumption (VO 2max ), lipid profile and antioxidant status were measured pre-and post-tests. Results: In the O group, there were significant decreases in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), increase in superoxide dismutase (SOD) activity and decrease in glutathione peroxidase (GPx) activity. In the J group, there were a significant increase in predicted VO 2max and decreases in TC and LDL-C. In the OJ group, there were significant decrease in percentage of body fat, increase in predicted VO 2max , high-density lipoprotein cholesterol (HDL-C) and SOD activity, and decreases in triglycerides (TG) and LDL-C. Conclusions: Eight weeks of regular jogging exercise combined with daily oat bran consumption elicited more beneficial effects on improving body composition, aerobic capacity, lipid profiles and SOD activity in young sedentary males.

“…At baseline, percentage of predicted lung function ((FEV 1 and forced vital capacity (FVC)) was reduced in the vast majority of the studies (online supplementary Web only file 1). FEV 1 could be improved in 3 of 20 studies by exercise training,27 42 44 whereas the FVC improved in only two studies 27 42. Peak expiratory flow (PEF) was the main lung function parameter that was improved, albeit mildly, by exercise.…”

Exercise training in children with asthma: a systematic review

et al. 2013

Exercise can provoke asthma symptoms, such as dyspnoea, in children with asthma. Exercise-induced bronchoconstriction (EIB) is prevalent in 40-90% of children with asthma. Conversely, exercise can improve physical fitness. The purpose of this paper is to provide a systematic review of the literature regarding the effects of exercise training in children with asthma, particularly in relation to: EIB, asthma control, pulmonary function, cardiorespiratory parameters and parameters of underlying pathophysiology. A systematic search in several databases was performed. Controlled trials that undertook a physical training programme in children with asthma (aged 6-18 years) were selected. Twenty-nine studies were included. Training had positive effects on several cardiorespiratory fitness parameters. A few studies demonstrated that training could improve EIB, especially in cases where there was sufficient room for improvement. Peak expiratory flow was the only lung function parameter that could be improved substantially by training. The effects of training on asthma control, airway inflammation and bronchial hyper-responsiveness were barely studied. Owing to the overall beneficial effects of training and the lack of negative effects, it can be concluded that physical exercise is safe and can be recommended in children with asthma. A training programme should have a minimum duration of 3 months, with at least two 60 min training sessions per week, and a training intensity set at the (personalised) ventilatory threshold. Further research is recommended regarding the effects of exercise on underlying pathophysiological mechanisms and asthma control in children with asthma.

“…Na asma, o efeito anti-inflamatório do exercício tem sido muito menos explorado, porém alguns estudos observaram que a prática regular de exercício físico pode reduzir o estresse oxidativo (Onur et al, 2011), o broncoespasmo induzido pelo exercício e o uso de corticosteroides (Neder et al, 1999;Fanelli et al 2007). Apesar destes estudos sugerirem indiretamente uma possível redução da inflamação pulmonar conhecemos apenas quatro estudos que avaliaram o efeito do treinamento físico na resposta inflamatória em pacientes asmáticos e seus resultados podem ser considerados controversos.…”
