Multigenerational obesity-induced perturbations in oocyte-secreted factor signalling can be ameliorated by exercise and nicotinamide mononucleotide.

Hum Reprod Open 2018 29;2018(3):hoy010. Epub 2018 May 29.

School of Women's and Children's Health, Fertility and Research Centre, University of New South Wales, Sydney, New South Wales 2052, Australia.

Study Question: Can maternal and offspring high-fat diet (HFD)-induced changes in mRNA expression levels in mice be ameliorated by interventions in female offspring?

Summary Answer: Our results indicate that exercise and nicotinamide mononucleotide (NMN) can ameliorate the negative effects of maternal and post-weaning HFD in female offspring.

What Is Known Already: Maternal and post-weaning HFD can perturb offspring developmental trajectories. As rates of maternal obesity are rising globally, there is a need for effective treatments in offspring to ameliorate the negative effects from a maternal obesogenic environment. Read More

Effects of Respiratory Muscle Endurance Training in Hypoxia on Running Performance.

Med Sci Sports Exerc 2019 Feb 15. Epub 2019 Feb 15.

Japan Institute of Sports Science, Tokyo, Japan.

Purpose: We hypothesized that respiratory muscle endurance training (RMET) in hypoxia induces greater improvements in respiratory muscle endurance with attenuated respiratory muscle metaboreflex and consequent whole-body performance. We evaluated respiratory muscle endurance and cardiovascular response during hyperpnoea and whole-body running performance before and after RMET in normoxia and hypoxia.

Methods: Twenty-one collegiate endurance runners were assigned to control (n=7), normoxic (n=7), and hypoxic (n=7) groups. Read More

Inactivity Induces Resistance to the Metabolic Benefits Following Acute Exercise.

J Appl Physiol (1985) 2019 Feb 14. Epub 2019 Feb 14.

Kinesiology and Health Education, University of Texas at Austin, United States.

Acute exercise improves postprandial lipemia, glucose tolerance, and insulin sensitivity, all of which are risk factors for cardiovascular disease. However, recent research suggests that prolonged sedentary behavior might abolish these healthy metabolic benefits. Accordingly, this study aimed to elucidate the impact of an acute bout of exercise on postprandial plasma triglyceride, glucose, and insulin concentrations after four days of prolonged sitting (~13.

A Validation Study of a Noninvasive Lactate Threshold Device.

Int J Exerc Sci 2019 1;12(2):221-232. Epub 2019 Jan 1.

Family and Community Health, Texas A&M AgriLife Extension Service, College Station, TX, USA.

The lactate threshold is considered a key marker of endurance exercise performance and identification of this threshold is important in writing an exercise training program. Unfortunately, assessment of the lactate threshold has traditionally required venous or capillary blood samples and a specialized meter to assess blood lactate concentrations. Recently, a consumer grade, non-invasive device was developed to determine muscle oxygenation and estimate the lactate threshold. Read More
