Objective: To compare the effectiveness of 2 home-based behavioral interventions for wheelchair users to promote exercise adoption and maintenance over 12 months.
Design: Randomized controlled trial, with participants stratified into groups based on disability type (stable, episodic, progressive) and support partner availability.
Setting: Exercise occurred in participant-preferred locations (eg, home, recreation center), with physiological data collected at a university-based exercise laboratory.
Participants: Inactive wheelchair users (N=128; 64 women) with sufficient upper arm mobility for arm-based exercise were enrolled. Participants on average were 45 years of age and lived with their impairment for 22 years, with spinal cord injury (46.1%) most commonly reported as causing mobility impairment.
Interventions: Both groups received home-based exercise interventions. The staff-supported group (n=69) received intensive exercise support, while the self-guided group (n=59) received minimal support. Both received exercise information, resistance bands, instructions to self-monitor exercise, regularly scheduled phone calls, and handwritten cards.
Main Outcome Measures: The primary outcome derived from weekly self-reported exercise. Secondary outcomes included physical fitness (aerobic/muscular) and predictors of exercise participation.
Results: The staff-supported group reported significantly greater exercise (∼17min/wk) than the self-guided group over the year (t=10.6, P=.00), with no significant between-group difference in aerobic capacity (t=.76, P=.45) and strength (t=1.5, P=.14).
Conclusions: Although the staff-supported group reported only moderately more exercise, the difference is potentially clinically significant because they also exercised more frequently. The staff-supported approach holds promise for encouraging exercise among wheelchair users, yet additional support may be necessary to achieve more exercise to meet national recommendations.

Effect of exercise training on modulating the TH17/TREG imbalance in individuals with severe COPD: A randomized controlled trial.
Pulmonology

Laboratory of Experimental Therapeutics, LIM-20, Department of Clinical Medicine, School of Medicine, University of Sao Paulo, Sao Paulo, Brazil.
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.
Residual Effects of Physical Exercise After Periods of Training Cessation in Older Adults: A Systematic Review With Meta-Analysis and Meta-Regression.
Scand J Med Sci Sports

Department of Physical Education and Sports, Faculty of Sport Sciences, University of Granada, Melilla, Spain.
We aimed to determine the persisting effects of various exercise modalities and intensities on functional capacity after periods of training cessation in older adults. A comprehensive search was conducted across the Cochrane Library, PubMed/MEDLINE, Scopus, and Web of Science Core Collection up to March 2024 for randomized controlled trials examining residual effects of physical exercise on functional capacity in older adults ≥ 60 years. The analysis encompassed 15 studies and 21 intervention arms, involving 787 participants.

Rationale: Obesity is an increasing medical issue not responding well to behavioural treatments beyond their initial weeks/months.
Aims And Objectives: Before suggesting surgical or pharmacological interventions, medical professionals might consider referrals to cost-effective, community-based behavioural treatments if stronger theoretical/empirical bases were demonstrated. Thus, evaluation of such is warranted.

Background: Despite the availability of various pharmacological and behavioural interventions, alcohol-related mortality is rising. This systematic review aimed to critically evaluate the existing literature on the association between glucagon-like peptide-1 receptor agonists use (GLP-1 RAs) and alcohol consumption.
Methods: Electronic searches were conducted on Ovid Medline, EMBASE, PsycINFO, clintrials.

α-Cyclodextrin (αCD), a cyclic hexasaccharide composed of six glucose units, is not digested in the small intestine but is completely fermented by gut microbes. Recently, we have reported that αCD supplementation for nonathlete men improved their 10 km biking times. However, the beneficial effects of αCD on exercise are not yet fully understood.
