Background And Objectives: The primary aim of this Stage IB randomized controlled trial (RCT) was to test the preliminary effects of a dual-task exergaming telerehabilitation intervention on cognition and aerobic fitness, compared to aerobic exercise (AEx) only and attention control (stretching) in older adults with subjective cognitive decline.
Research Design And Methods: This RCT randomized 39 participants on a 2:1:1 allocation ratio to supervised exergame (n = 20), AEx (n = 11), and stretching (n = 8) for 12 weeks. The dual-task exergaming was concurrent moderate-intensity cycling and BrainFitRx cognitive telerehabilitation. Cognition was assessed by NIH Toolbox Cognitive Battery and aerobic fitness by 6-minute walk test (6MWT) and shuttle walk test.
Results: The participants were 74.6 (7.4) years old and 69% were female. The effect of time was significant, F(1, 23.9) = 13.16, p = .001, for the Fluid Composite score, and significant within-group changes were seen for the exergame group, t(14.08) = 2.53, p = .024, d = 0.33. Between-group changes did not reach significant levels for any cognitive test. Between-group changes for the 6MWT were not significant.
Discussion And Implications: The exergame participants further improved their fluid cognition, whereas the AEx and stretching groups did not, indicating a potential synergistic effect from AEx and cognitive training. The aerobic fitness changes were similar between the exergame and AEx-only groups, indicating that the feasibility of adding cognitive training to AEx concurrently without sacrificing gains in aerobic fitness from AEx. This study shows the flexibility of exergame delivery and its potentially therapeutic effects in persons at risk for Alzheimer's dementia.

Background: Chronic obstructive pulmonary disease (COPD) induces an imbalance in T helper (Th) 17/regulatory T (Treg) cells that contributes to of the dysregulation of inflammation. Exercise training can modulate the immune response in healthy subjects.
Objective: We aimed to evaluate the effects of exercise training on Th17/Treg responses and the differentiation of Treg phenotypes in individuals with COPD.

Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.

The gold standard to assess the aerobic capacity in physically active subjects and athletes is the maximal oxygen consumption test (VO2-max), which involves analysis of exhaled-gases and cardiorespiratory variables obtained via the breath-by-breath method in an ergospirometer during an incremental exercise. However, this method cannot elucidate metabolic changes at the muscular level. Near-infrared spectroscopy (NIRS) has emerged as a valuable technology to evaluate local oxygen levels (Tissular Saturation Index, TSI) by quantifying the concentrations of oxygenated (O2-Hb) and deoxygenated (H-Hb) hemoglobin in the microvasculature of tissues.

Background: Attentional engagement, the ability to maintain focus on relevant tasks, plays a crucial role in optimizing human performance. Studies have shown that athletes exhibit superior attentional engagement compared to non-athletes; however, it remains unclear if these benefits persist in non-sport-related tasks or differ across types of sports expertise, such as open-skill versus closed-skill sports.
Methods: Ninety-three young adults, divided into open-skill athletes ( = 31), closed-skill athletes ( = 31), and a control group ( = 31), completed an auditory oddball task while the P3 component of event-related potentials was measured to assess attentional processing.
