Obese adolescents who gained/maintained or lost weight had similar body composition and cardiometabolic risk factors following a multidisciplinary intervention
This study aimed to assess the impact of a multidisciplinary program of obesity treatment (MPOT) on adolescents who have maintained/gained weight or lost weight. Eighty-six adolescents aged 10–18 years were allocated in either the intervention group (IG; n = 44) or the control group (CG; n = 42). Each group was divided into two more groups: weight maintenance/gain and weight loss, as assessed after the intervention. The MPOT lasted 16 weeks and was conducted by a multidisciplinary team based on cognitive-behavioral therapy. We analyzed body composition and cardiometabolic parameters prior to and after the interventio...

Effect of walking speed and placement position interactions in determining the accuracy of various newer pedometers
In conclusion, most pedometers examined were accurate when they were placed at the waist, chest, and armband irrespective of the walking speed or terrain. However, some pedometers had reduced accuracy when they were kept in a pocket or placed in a purse, especially at a slower and faster walking speeds. (Source: Journal of Exercise Science and Fitness)

Effects of ginger (Zingiber officinale Roscoe) supplementation and resistance training on some blood oxidative stress markers in obese men
This study was conducted to assess the effects of ginger (Zingiber officinale Roscoe) supplementation and progressive resistance training (PRT) on some nonenzymatic blood [total antioxidant capacity (TAC) and malondialdehyde (MDA)] oxidative stress markers in obese men. Thirty-two obese males (body mass index ≥30, aged 18–30 years) were randomized to one of the following four groups: a placebo (PL; n = 8); resistance training plus placebo (RTPL; n = 8); resistance training plus ginger supplementation (RTGI; n = 8); and ginger supplementation only (GI; n = 8). Participants in the RTGI and GI groups consumed 1 g...

Effects of 12-week high-intensity interval training on plasma visfatin concentration and insulin resistance in overweight men
In conclusion, adding a low-volume 20-minute HIIT (three times/week) to an energy-deficit diet not only can improve the efficiency of weight-loss program in the reduction of body fat, plasma visfatin levels, and HOMA-IR, but also has a reservation effect on lean body mass.

Interleukin-6 G-174C gene polymorphism and susceptibility to upper respiratory tract infection among endurance athletes
In conclusion, findings from this study have identified a potential role of genetic variation in influencing the risk for URTI in athletic populations and single nucleotide polymorphisms in the IL-6 genes were associated with an altered risk profile. These measures may have a predictive value in the identification of individuals who are more likely to experience recurrent infections when exposed to high physical stress in the areas of athletic endeavor.

Associations of health disparities and physical activity with children's health and academic problems
This study was aimed at examining the associations between health disparities and physical activity, and their contributions to health and academic problems in schoolchildren. Pertinent data from a community-wide survey were analyzed, which included 2930 households with schoolchildren aged 7–14 years. Associations between the parents' self-reported race/ethnicity, parental education, household income, children's health status, physical activity, and academic problems were determined by Chi-square and logistic regression analyses. Contributory factors for children's health status, physical activity, and academic problems ...

Antioxidant enzymes and oxidative stress adaptation to exercise training: Comparison of endurance, resistance, and concurrent training in untrained males
Publication date: June 2014 Source:Journal of Exercise Science & Fitness, Volume 12, Issue 1 Author(s): Kamal Azizbeigi , Stephen R. Stannard , Sirvan Atashak , Marjan Mosalman Haghighi The aim of this study was to compare the effect of endurance training (ET), resistance training (RT), and concurrent training (CT) on circulating antioxidant capacity and oxidative stress. For this purpose, 30 men aged 21.7 ± 2.4 years were assigned to the following three training groups: ET, which included continuous running with incremental intensity that was increased up to 80% of maximal heart rate (n = 10); RT, whi...

Is athletic background associated with a future lower prevalence of risk factors for chronic disease?
Publication date: Available online 23 July 2014 Source:Journal of Exercise Science & Fitness Author(s): Cristiano H.X. Batista , José M. Soares This cross-sectional study examined whether the prevalence of behavioral and biological risk factors of former elite athletes (both men and women), differed from nonelite athletes and nonathletes. A total of 491 individuals (225 former elite athletes, 168 former nonelite athletes, and 98 nonathletes) participated in this study. Major behavioral and biological risk factors identified in the 2002 World Health Report were assessed. Apart from alcohol consumption, former...

Effects of concurrent training on inflammatory markers and expression of CD4, CD8, and HLA-DR in overweight and obese adults
This study investigated the effect of concurrent training on anthropometric, inflammatory, and immunological parameters in overweight and obese adults. Fourteen sedentary volunteers (men and women) with a body mass index between 25 kg/m2 and 39.9 kg/m2 from Porto Alegre, Brazil attended a 12-week course of concurrent training. We analyzed: prior to and after training, anthropometric parameters, cytokine serum levels (interleukin 6, tumor necrosis factor α, interferon γ, interleukin 17A and interleukin 10; measured by enzyme-linked immunosorbent assay), high-sensitive C reactive protein (measured by turbidimetry), and t...

Effects of high and low volume of strength training on muscle strength, muscle volume and lipid profile in postmenopausal women
Publication date: Available online 10 September 2014 Source:Journal of Exercise Science & Fitness Author(s): Cleiton Silva Correa , Bruno Costa Teixeira , Renata Lopes Kruger , Aline Bittencourt , Leandro Lemos , Nise Ribeiro Marques , Régis Radaelli , Alvaro Reischak-Oliveira , Ronei Silveira Pinto Changes in lipid profile are considered a risk factor for cardiovascular disease (CVD), especially in postmenopausal woman who have been associated with age-related loss of muscle mass. The beneficial role of aerobic exercise in the prevention of CVD has been well documented. However, the effect of strengt...
