Am J Hum Biol 2022 Jun 25:e23775. Epub 2022 Jun 25.

Health Sciences Center, Federal University of Rio Grande do Norte, Natal, Brazil.

Background: Hand-wrist radiography is the gold standard for the assessment of skeletal age (SA) and the assignment of biological maturation (BM) status. However, its practical use in the field is questioned, prompting the development of anthropometric equations to estimate BM. However, there is no consensus on the reliability of these equations in relation to hand-wrist X-rays. Read More

Translational Significance of the LINE-1 Jumping Gene in Skeletal Muscle.

Exerc Sport Sci Rev 2022 Jun 24. Epub 2022 Jun 24.

Department of Molecular Biology, Cell Biology and Biochemistry, Center on the Biology of Aging, Brown University, Providence, Rhode Island, USA.

Abstract: Retrotransposons are gene segments that proliferate in the genome, and the Long INterspersed Element 1 (LINE-1, or L1) retrotransposon is active in humans. Although older mammals show enhanced skeletal muscle L1 expression, exercise generally reverses this trend. We hypothesize skeletal muscle L1 expression affects muscle physiology, and additional innovative investigations are needed to confirm this hypothesis. Read More

Sympathetic vasomotor outflow during low-intensity leg cycling in healthy older males.

Exp Physiol 2022 Jun 24. Epub 2022 Jun 24.

Department of Biomedical Engineering, Toyo University, Kawagoe, Japan.

New Findings: What is the central question of this study? Sympathetic vasomotor outflow is reduced during low-intensity dynamic leg exercise in younger individuals. Does aging influence the sympathoinhibitory effect during low-intensity leg cycling? What is the main finding and its importance? Muscle sympathetic nerve activity (MSNA) during low-intensity cycling decreased in older males, as seen in young males. It is possible that cardiopulmonary baroreflex-mediated inhibition of sympathetic vasomotor outflow during dynamic leg exercise is preserved in healthy older males. Read More

Transcranial magnetic stimulation of the brain: What is stimulated? - A consensus and critical position paper.

Clin Neurophysiol 2022 May 18;140:59-97. Epub 2022 May 18.

Department of Neurology, Fukushima Medical University, Fukushima, Japan; Fukushima Global Medical Science Centre, Advanced Clinical Research Centre, Fukushima Medical University, Fukushima, Japan.

Transcranial (electro)magnetic stimulation (TMS) is currently the method of choice to non-invasively induce neural activity in the human brain. A single transcranial stimulus induces a time-varying electric field in the brain that may evoke action potentials in cortical neurons. The spatial relationship between the locally induced electric field and the stimulated neurons determines axonal depolarization. Read More

The role of resistance exercise training for improving cardiorespiratory fitness in healthy older adults: a systematic review and meta-analysis.

Age Ageing 2022 Jun;51(6)

Centre of Metabolism, Ageing and Physiology (COMAP), School of Medicine, Royal Derby Hospital Centre, University of Nottingham, Derby DE22 3DT, UK.

Background: Declines in cardiorespiratory fitness (CRF) and muscle mass are both associated with advancing age and each of these declines is associated with worse health outcomes. Resistance exercise training (RET) has previously been shown to improve muscle mass and function in the older population. If RET is also able to improve CRF, as it has been shown to do in younger populations, it has the potential to improve multiple health outcomes in the expanding older population. Read More
