Effect of 12 weeks of periodized resistance training upon total plasma adiponectin concentration in healthy young men

© 2015 National Strength and Conditioning Association. The effects of resistance training on adiponectin have thus far yielded equivocal results. However, the effect of periodized resistance training on plasma adiponectin in offspring of type 2 diabetic and nondiabetic (ND) parents (first-degree family history) has yet to be determined. Untrained healthy young men with and without a first-degree family history of type 2 diabetes were assigned to an exercise intervention group (E) or an active control group (C). The E group performed a 12-week periodized resistance training program, whereas the C group did not participate in any structured exercise program. Fasting plasma samples were obtained pre- and posttraining. Total plasma adiponectin changed significantly in the E group (33.7 ± 14.7%, p 0.025) but not in the C group (10.8 ± 19.2%). Offspring of type 2 diabetic parents subjects had significantly greater improvements in plasma adiponectin (69.3 ± 34.8%) compared with ND subjects (-3.2 ± 29.9%, p 0.046). Regular aerobic exercise was significantly correlated with average plasma adiponectin (r 0.32), whereas first-degree family history of type 2 diabetes (r -0.58) and decreases in body fat percentage (r -0.77) were inversely correlated with average plasma adiponectin. Periodized high-intensity resistance training seems to increase plasma adiponectin, particularly in individuals with a first-degree family history of type 2 diabetes or those who experience a significant loss of fat mass. The direct correlation between regular aerobic exercise and adiponectin further suggests that a combination of aerobic and resistance training yields greater improvements in plasma adiponectin compared with resistance training alone

The X-Trials: Neural Correlates of an Inhibitory Control Task in Children and Adults

Event-related potentials (ERPs) were used to examine developmental differences between adults and 6-year-old children in the neural processes involved in an inhibitory control task. Twenty adults and 21 children completed a task that required them to selectively respond to target stimuli while inhibiting responses to equally salient non-target stimuli. Because this task had been previously studied using functional magnetic resonance imaging (fMRI), the relation between the fMRI and ERP findings was informally examined. The results indicate that latency and amplitude of the P3 differentiated the different types of trials. However, the pattern of event-related neural activity differed for adults and children. These results, which suggest that adults and children may be using different processes to perform this task, have implications for the interpretation of the previous fMRI findings

Scholarship of Teaching and Learning: Developing a Culture of Assessment

The Scholarship of Teaching and Learning Initiative at Hostos Community College focuses on melding assessment and faculty development through a scholastic approach. In order to facilitate a campus-wide engagement in assessment, particularly related to the effectiveness of classroom instruction, the focus remains on individual expectations and talents, professional responsibilities, and using formative and summative assessment to improve student success and recidivism. This was initiated through open dialogue on the critical need for inquiry-based instruction, targeted presentations, and a sustainable network of support

Draft Genome Sequence of Pseudoalteromonas sp. Strain JC3

We report the draft genome sequence for Pseudoalteromonas sp. strain JC3, an isolate obtained from an aquaculture facility for whiteleg shrimp (Litopenaeus vannamei). The JC3 genome suggests multiple mechanisms for microbial interactions, including a type VI secretion system and potential for antibiotic production

Growing Stronger: Strength Training for Older Adults

In choosing to read this book, you have taken the first step on a journey toward greater strength and vitality. Growing Stronger was written for you—the older adult who wants to grow stronger, healthier, more active, and more independent. You may be inactive or only mildly active at the moment. You may know that regular exercise is important for your health and well-being and want to get started on a program of physical activity. But you may feel that you don’t have the necessary information. Perhaps you are concerned that because of your age or health problems physical activity may not be safe for you. Or perhaps you have had trouble finding or staying with a suitable program. This book gives you a safe, simple, and highly effective exercise program based on the principles of strength training. Studies at laboratories around the world have shown that strength training benefits women and men of all ages and all levels of fitness. According to Physical Activity and Health: A Report of the Surgeon General (1996), experts agree that aerobic activities should be supplemented with strength-developing exercises at least twice per week
