Cardiorespiratory fitness levels and body mass index of pre-adolescent children and older adults during the COVID-19 pandemic.

Introduction: The social and behavioral effects of the COVID-19 pandemic have impacted the health and physiology of most people, including those never diagnosed with COVID-19. While the impact of the pandemic has been felt across the lifespan, its effects on cardiorespiratory fitness (commonly considered a reflection of total body health) of older adults and children may be particularly profound due to social distancing and stay-at-home advisories, as well as the closure of sport facilities and non-essential businesses. The objective of this investigation was to leverage baseline data from two ongoing clinical trials to determine if cardiorespiratory fitness and body mass index were different during COVID-19 relative to before COVID-19 in older adults and children. Methods: Healthy older individuals (N = 593; 65-80 years) and 200 typically developing children (8-10 years) completed a graded maximal exercise test and had their height and weight measured. Results: Results revealed that older adults and children tested during COVID-19 had significantly lower cardiorespiratory fitness levels than those tested before COVID-19 shutdowns (older adults: 30% lower; children: 53% lower; p's ≤ 0.001). In addition, older adults and children tested during COVID-19 had significantly higher BMI (older adults: 31.34 ± 0.57 kg/m2, p = 0.004; children: 19.27 ± 0.44 kg/m2, p = 0.05) than those tested before COVID-19 shutdowns (older adults: 29.51 ± 0.26 kg/m2, children: 18.13 ± 0.35 kg/m2). However, these differences in BMI did not remain significant when controlling for cardiorespiratory fitness. Discussion: Results from this investigation indicate that the COVID-19 pandemic, and behavior changes taken to reduce potential exposure, may have led to lower cardiorespiratory fitness levels in older adults and children, as well as higher body mass index. These findings provide relevant public health information as lower cardiorespiratory fitness levels and higher body mass indexes recorded during the pandemic could have far-reaching and protracted health consequences. Public health guidance is needed to encourage physical activity to maintain cardiorespiratory fitness and healthy body composition.

Cardiac rehabilitation for older adults: current evidence and future potential.

INTRODUCTION: Growth of the older adult demographic has resulted in an increased number of older patients with cardiovascular disease (CVD) in combination with comorbid diseases and geriatric syndromes. Cardiac rehabilitation (CR) is utilized to promote recovery and improve outcomes, but remains underutilized, particularly by older adults. CR provides an opportunity to address the distinctive needs of older adults, with focus on CVD as well as geriatric domains that often dominate management and outcomes. AREAS COVERED: Utility of CR for CVD in older adults as well as pertinent geriatric syndromes (e.g. multimorbidity, frailty, polypharmacy, cognitive decline, psychosocial stress, and diminished function) that affect CVD management. EXPERT OPINION: Mounting data substantiate the importance of CR as part of recovery for older adults with CVD. The application of CR as a standard therapy is especially important as the combination of CVD and geriatric syndromes catalyzes functional decline and can trigger progressive clinical deterioration and dependency. While benefits of CR for older adults with CVD are already evident, further reengineering of CR is necessary to better address the needs of older candidates who may be frail, especially as remote and hybrid formats of CR are becoming more widespread.

Modified Application of Cardiac Rehabilitation in Older Adults (MACRO) Trial: Protocol changes in a pragmatic multi-site randomized controlled trial in response to the COVID-19 pandemic.

BACKGROUND: Older adults are at higher risk for cardiovascular disease and functional decline, often leading to deterioration and dependency. Cardiac rehabilitation (CR) provides opportunity to improve clinical and functional recovery, yet participation in CR decreases with age. Modified Application of CR in Older Adults (MACRO) is a National Institute on Aging (NIA)-funded pragmatic trial that responds to this gap by aiming to increase enrollment of older adults into CR and improving functional outcomes. This article describes the methodology and novel features of the MACRO trial. METHODS: Randomized, controlled trial of a coaching intervention (MACRO-I) vs. usual care for older adults (age ≥ 70 years) eligible for CR after an incident cardiac hospitalization. MACRO-I incorporates innovations including holistic risk assessments, flexible CR format (i.e., helping patients to select a CR design that aligns with their personal risks and preferences), motivational prompts, nutritional emphasis, facilitated deprescription, enhanced education, and home visits. Key modifications were necessitated by the COVID-19 pandemic, including switching from a performance-based primary endpoint (Short Physical Performance Battery) to a patient-reported measure (Activity Measure for Post-Acute Care Computerized Adaptive Testing). Changes prompted by COVID-19 maintain the original intent of the trial and provide key methodologic advantages. CONCLUSIONS: MACRO is exploring a novel individualized coaching intervention to better enable older patients to participate in CR. Due to COVID-19 many aspects of the MACRO protocol required modification, but the primary objective of the trial is maintained and the updated protocol will more effectively achieve the original goals of the study.

Rapid Transition to Telehealth Group Exercise and Functional Assessments in Response to COVID-19.

Exercise is critical for health maintenance in late life. The COVID-19 shelter in place and social distancing orders resulted in wide-scale interruptions of exercise therapies, placing older adults at risk for the consequences of decreased mobilization. The purpose of this paper is to describe rapid transition of the Gerofit facility-based group exercise program to telehealth delivery. This Gerofit-to-Home (GTH) program continued with group-based synchronous exercise classes that ranged from 1 to 24 Veterans per class and 1 to 9 classes offered per week in the different locations. Three hundred and eight of 1149 (27%) Veterans active in the Gerofit facility-based programs made the transition to the telehealth delivered classes. Participants' physical performance testing continued remotely as scheduled with comparisons between most recent facility-based and remote testing suggesting that participants retained physical function. Detailed protocols for remote physical performance testing and sample exercise routines are described. Translation to remote delivery of exercise programs for older adults could mitigate negative health effects.

Cardiac Rehabilitation During COVID-19 Pandemic: Highlighting the Value of Home-Based Programs.

Cardiac rehabilitation (CR) is a class I treatment for cardiovascular disease, however, underutilization of these services remains. Home-based CR (HBCR) models have been implemented as a potential solution to addressing access barriers to CR services. Home-based models have been shown to be effective, however, there continues to be large variation of protocols and minimal evidence of effectiveness in higher risk populations. In addition, lack of reimbursement models has discouraged the widespread adoption of HBCR. During the coronavirus 2019 (COVID-19) pandemic, an even greater gap in CR care has been present due to decreased availability of on-site services. The COVID-19 pandemic presents a time to highlight the value and experiences of home-based models as clinicians search for ways to continue to provide care. Continued review and standardization of HBCR models are essential to provide care for a wider range of patients and circumstances.
