Community-based exercise programs for older adults play a potentially important role in mitigating the decline in functional outcomes, body composition, psychosocial outcomes, and cardiovascular health outcomes that commonly occurs with advancing age. There is a limited understanding of the characteristics and effectiveness of community-based exercise programs, particularly when those programs are offered outside metropolitan areas. Rural/regional settings face unique challenges, such as limited access to equipment/resources, transportation, and services, as well as significant costs to run programs. The objective of this scoping review was to characterise studies in the field that have aimed to implement community-based programs in settings identified as rural / regional. A secondary aim was to establish guidance for future exercise programs in this setting and highlight future research directions. A total of 12 studies were conducted in settings identified as rural/regional areas in various countries across the world were included. Of the included studies, five were randomised controlled trials. The majority of included studies reported on functional outcomes (83%) and psychosocial outcomes (75%), yet only 42% reported body composition, 17% reported cardiovascular health and 17% reported dietary outcomes. Low male representation was observed, with women outnumbering men in 7 of 12 studies. There was also minimal investigation of qualitative outcomes in existing community-based exercise programs in rural/regional settings, presenting a key gap for future research to address.

D soccer match play) immediately followed by an exhaustive run. Methods: Following familiarization, 16 male soccer players completed an exhaustive intermittent exercise protocol on two further occasions (T1 and T2) separated by approximately 14 d. Ten days before T2, the subjects were assigned, in a double-blind manner, to receive either phosphatidylserine (PS) or a placebo (P). Exercise time to exhaustion, sprint performance, ratings of perceived exertion, and HR were recorded throughout both main exercise trials. Venous blood samples were obtained at rest (preexercise), 15 min following exercise (postexercise), 24 h after exercise (post–24 h), and 48 h after exercise (post–48 h). Results: Preexercise and postexercise concentrations of plasma γ-tocopherol were increased following supplementation in PS, although supplementation had no effect on plasma concentrations of other nonenzymatic antioxidants (vitamin C, α-tocopherol, retinol, and β-carotene). Serum cortisol concentrations, perceived soreness, markers of muscle damage (creatine kinase (CK) and myoglobin (Mb)), and lipid peroxidation (hydroperoxides and conjugated diene lag times) were elevated to an equal extent in PS and P following exhaustive exercise before and following supplementation. The changes in running times to exhaustion from T1 to T2 in PS and P were 4.2 ± 0.7 and −3.7 ± 4.2%, respectively (P = 0.084). Conclusion: Supplementation with phosphatidylserine was not effective in attenuating the cortisol response, perceived soreness, and markers of muscle damage and lipid peroxidation following exhaustive running; however, supplementation tended to increase running time to exhaustion. Therefore, future research should be undertaken to investigate the potential ergogenic properties of this supplement....

Aims and objectives: This integrative review aimed to draw conclusions from evidence on how registered nurses are measuring respiratory rates for acute care patients.Background: Despite the growing research supporting respiratory rate as an early indicator for clinical deterioration, respiratory rate has consistently been the least frequently measured and accurately documented vital sign.Design: An integrative review.Methods: A systematic literature search was conducted in June 2022 in four databases: CINAHL, PubMed, Medline and Scopus. Quality appraisal was undertaken using the Joanna Briggs Institute's Checklist. PRISMA guidelines were followed to ensure explicit reporting and reported in the PRISMA checklist.Results: Overall, 9915 records were identified, and 19 met the inclusion criteria. Of these 19 articles, seven themes emerged: estimation and digit preference, lack of understanding and knowledge, not valuing the clinical significance of respiratory rate, oxygen saturation substitute, interobserver agreement, subjective concern and count duration. A high prevalence of bias, estimation and incorrect technique was evident. A total of 15 articles reported specifically on how registered nurses are measuring respiratory rates on general medical and surgical wards.Conclusions: Despite its importance, this integrative review has determined that respiratory rates are not being assessed correctly by nursing staff in the acute care environment. Evidence of using estimation, value bias or quick count and multiply techniques are emerging themes which urgently require further research.No patient or public contribution.
