RESUMEN

Background: Cancer disparities exist for Hispanic men with prostate cancer and their caregivers that could be reduced through exercise. Exercising Together© is a six-month, evidence-based dyadic resistance training program that promotes teamwork between prostate cancer survivors and their spouses to improve physical, mental, and relational health outcomes. The purpose of this study was to elicit feedback and recommendations from stakeholders on the Exercising Together© intervention to inform the cultural adaptation of this program for Hispanic men with prostate cancer. Methods: We conducted a virtual Community Engagement Studio (V-CES) with community expert stakeholders representing the Hispanic and cancer care communities in Southern Arizona. The V-CES process included orientation, presentation of the research, guided discussion, and evaluation. The V-CES was audio recorded, transcribed, and rapidly analyzed to identify actionable feedback and contextual adaptations. Results: Nine stakeholders (6/9 male; 5/9 Hispanic) completed all V-CES activities. Through stakeholder engagement and feedback from the V-CES, adaptations to the original Exercising Together© intervention included: (1) inclusion of the cancer survivor's identified caregiver, who may not be a spouse; (2) availability in English and Spanish; (3) shortening the intervention to 3 months; (4) remote delivery of the intervention; and (5) incorporation of low burden procedures. Conclusion: Findings from our V-CES informed the adaptation of a culturally relevant dyadic progressive resistance training program for Hispanic men with prostate cancer and their caregivers.

RESUMEN

PURPOSE: To determine whether strength training or tai ji quan can reduce frailty in older, postmenopausal women treated with chemotherapy for cancer. METHODS: We conducted a secondary data analysis from a 3-arm, single-blind, randomized controlled trial where older (50-75 years), postmenopausal women cancer survivors were randomized to supervised group exercise programs: tai ji quan, strength training, or stretching control for 6 months. We assessed frailty using a 4-criteria model consisting of weakness, fatigue, inactivity, and slowness. Using logistic regression, we determined whether the frailty phenotype (pre-frailty or frailty) decreased post-intervention, how many and which frailty criteria decreased, and what characteristics identified women most likely to reduce frailty. RESULTS: Data from 386 women who completed baseline and 6-month testing were used (mean age of 62.0 ± 6.4 years). The odds of reducing overall frailty over 6 months were significantly higher in the strength training group compared to controls (OR [95%CI] 1.86 [1.09, 3.17]) but not for tai ji quan (1.44 [0.84, 2.50]). Both strength training (OR 1.99 [1.10, 3.65]) and tai ji quan (OR 2.10 [1.16, 3.84]) led to significantly higher odds of reducing ≥ 1 frailty criterion compared to controls. Strength training led to a three-fold reduction in inactivity (p < 0.01) and tai ji quan to a two-fold reduction in fatigue (p = 0.08) versus control. Higher baseline BMI, comorbidity score, and frailty status characterized women were more likely to reduce frailty than other women. CONCLUSIONS: Strength training appears superior to tai ji quan and stretching with respect to reducing overall frailty phenotype among postmenopausal women treated with chemotherapy for cancer, but tai ji quan favorably reduced the number of frailty criteria. TRIAL REGISTRATION: ClinicalTrials.gov identifier: GET FIT was registered as a clinical trial in clinicaltrials.gov: NCT01635413. IMPLICATIONS FOR CANCER SURVIVORS: Supervised, group exercise training that emphasizes strength training and/or tai ji quan may help combat accelerated aging and reduce frailty after cancer treatment.

RESUMEN

INTRODUCTION: The number of randomized controlled trials (RCTs) investigating the effects of exercise among cancer survivors has increased in recent years; however, participants dropping out of the trials are rarely described. The objective of the present study was to assess which combinations of participant and exercise program characteristics were associated with dropout from the exercise arms of RCTs among cancer survivors. METHODS: This study used data collected in the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) study, an international database of RCTs investigating the effects of exercise among cancer survivors. Thirty-four exercise trials, with a total of 2467 patients without metastatic disease randomized to an exercise arm were included. Harmonized studies included a pre and a posttest, and participants were classified as dropouts when missing all assessments at the post-intervention test. Subgroups were identified with a conditional inference tree. RESULTS: Overall, 9.6% of the participants dropped out. Five subgroups were identified in the conditional inference tree based on four significant associations with dropout. Most dropout was observed for participants with BMI >28.4 kg/m2 , performing supervised resistance or unsupervised mixed exercise (19.8% dropout) or had low-medium education and performed aerobic or supervised mixed exercise (13.5%). The lowest dropout was found for participants with BMI >28.4 kg/m2 and high education performing aerobic or supervised mixed exercise (5.1%), and participants with BMI ≤28.4 kg/m2 exercising during (5.2%) or post (9.5%) treatment. CONCLUSIONS: There are several systematic differences between cancer survivors completing and dropping out from exercise trials, possibly affecting the external validity of exercise effects.

RESUMEN

We assessed a subset of behavioral indicators from the American Heart Association Life's Essential 8 cardiovascular health (CVH) construct-diet, physical activity, sleep, and nicotine exposure-and quantified associations in scores between members of 12 grandparent-grandchild dyads (grandparents, 52-70 years old; children, 7-12 years old). We also assessed the number of adverse childhood experiences from the dyads. Using the Life's Essential 8 scoring algorithm (0-100, with 100 as optimal), we calculated averages and used Spearman's ρ correlation to quantify associations. Mean score was 67.5 (±12.4) for grandparents and 63.0 (±11.2) for grandchildren. Mean scores for the dyad members were significantly correlated ( r = 0.66, P < .05). The mean numbers of adverse childhood experiences were 7.0 and 5.8 for the grandparents and grandchildren, respectively. The results indicate that CVH in these dyads was suboptimal and interrelated. Adverse childhood experiences in this analysis surpass levels reported as high risk for poor CVH. Our findings suggest that dyadic-based interventions to improve CVH are warranted.

RESUMEN

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating and dose-limiting side effect of systemic cancer therapy. In many cancer survivors, CIPN persists after treatment ends and is associated with functional impairments, abnormal gait patterns, falls, and diminished quality of life. However, little is known regarding which patients are most likely to develop CIPN symptoms that impair mobility and increase fall risk, when this risk develops, or the optimal timing of early intervention efforts to mitigate the impact of CIPN on functioning and fall risk. This study will address these knowledge gaps by (1) characterizing trajectories of symptoms, functioning, and falls before, during, and after treatment in adults prescribed neurotoxic chemotherapy for cancer; and (2) determining the simplest set of predictors for identifying individuals at risk for CIPN-related functional decline and falls. METHODS: We will enroll 200 participants into a prospective, observational study before initiating chemotherapy and up to 1 year after completing chemotherapy. Eligible participants are aged 40-85 years, diagnosed with stage I-III cancer, and scheduled to receive neurotoxic chemotherapy. We perform objective assessments of vibratory and touch sensation (biothesiometry, tuning fork, monofilament tests), standing and dynamic balance (quiet stance, Timed-Up-and-Go tests), and upper and lower extremity strength (handgrip dynamometry, 5-time repeated chair stand test) in the clinic at baseline, every 4-6 weeks during chemotherapy, and quarterly for 1 year post-chemotherapy. Participants wear devices that passively and continuously measure daily gait quality and physical activity for 1 week after each objective assessment and self-report symptoms (CIPN, insomnia, fatigue, dizziness, pain, cognition, anxiety, and depressive symptoms) and falls via weekly electronic surveys. We will use structural equation modeling, including growth mixture modeling, to examine patterns in trajectories of changes in symptoms, functioning, and falls associated with neurotoxic chemotherapy and then search for distinct risk profiles for CIPN. DISCUSSION: Identifying simple, early predictors of functional decline and fall risk in adults with cancer receiving neurotoxic chemotherapy will help identify individuals who would benefit from early and targeted interventions to prevent CIPN-related falls and disability. TRIAL REGISTRATION: This study was retrospectively registered with ClinicalTrials.gov (NCT05790538) on 3/30/2023.

RESUMEN

Purpose: To determine whether strength training or tai ji quan can reduce frailty in older, postmenopausal women treated with chemotherapy for cancer.

RESUMEN

This review focuses on the effects of exercise on various health-related outcomes in cancer survivors, encompassing body composition, cognitive function (including sleep), and gut microbiome health. By analyzing multiple studies, we aimed to summarize the existing evidence and shed light on underlying mechanisms. The findings strongly suggest that exercise serves as a multifaceted non-pharmacological strategy, playing a significant role in improving the overall health of cancer survivors by effectively reducing inflammation and oxidative stress. Exercise plays a crucial role in preventing muscle wasting, diminishing the presence of reactive oxygen species and pro-inflammatory cytokines, and enhancing antioxidant systems. Furthermore, exercise displays notable benefits in terms of executive cognitive functioning and fatigue alleviation, largely attributed to its anti-inflammatory impact on the central nervous system and its ability to induce neurogenesis via growth factors. Additionally, exercise positively influences microbial diversity, reduces gut inflammation, and enhances neurogenesis through the gut-brain axis. Our key findings underscore the reduction of oxidative stress and inflammation as primary mechanisms by which exercise effectively enhances health outcomes in cancer survivors. By delving deeper into these candidate mechanisms, we aim to provide valuable guidance for future research and interventions targeting the symptoms experienced by cancer survivors.

RESUMEN

PURPOSE: This individual participant data meta-analysis (IPD-MA) assesses exercise effects on self-reported cognitive functioning (CF) and investigates whether effects differ by patient-, intervention-, and exercise-related characteristics. METHODS: IPD from 16 exercise RCTs, including 1987 patients across multiple types of non-metastatic cancer, was pooled. A one-stage IPD-MA using linear mixed-effect models was performed to assess exercise effects on self-reported CF (z-score) and to identify whether the effect was moderated by sociodemographic, clinical, intervention- and exercise-related characteristics, or fatigue, depression, anxiety, and self-reported CF levels at start of the intervention (i.e., baseline). Models were adjusted for baseline CF and included a random intercept at study level to account for clustering of patients within studies. A sensitivity analysis was performed in patients who reported cognitive problems at baseline. RESULTS: Minimal significant beneficial exercise effects on self-reported CF (ß=-0.09 [-0.16; -0.02]) were observed, with slightly larger effects when the intervention was delivered post-treatment (n=745, ß=-0.13 [-0.24; -0.02]), and no significant effect during cancer treatment (n=1,162, ß=-0.08 [-0.18; 0.02]). Larger effects were observed in interventions of 12 weeks or shorter (ß=-0.14 [-0.25; -0.04]) or 24 weeks or longer (ß=-0.18 [-0.32; -0.02]), whereas no effects were observed in interventions of 12-24 weeks (ß=0.01 [-0.13; 0.15]). Exercise interventions were most beneficial when provided to patients without anxiety symptoms (ß=-0.10 [-0.19; -0.02]) or after completion of treatment in patients with cognitive problems (ß=-0.19 [-0.31; -0.06]). No other significant moderators were identified. CONCLUSIONS: This cross-cancer IPD meta-analysis observed small beneficial exercise effects on self-reported CF when the intervention was delivered post-treatment, especially in patients who reported cognitive problems at baseline. IMPLICATIONS FOR CANCER SURVIVORS: This study provides some evidence to support the prescription of exercise to improve cognitive functioning. Sufficiently powered trials are warranted to make more definitive recommendations and include these in the exercise guidelines for cancer survivors.

RESUMEN

PURPOSE: To compare the efficacy of tai ji quan versus strength training to prevent falls after chemotherapy in older, postmenopaual women. METHODS: We conducted a three-arm, single-blind, randomized controlled trial where older (50+ years), postmenopausal women cancer survivors participated in one of three supervised group exercise programs (tai ji quan, strength training, or stretching control) twice weekly for 6 months and were followed up 6 months after training stopped. The primary outcome was the incidence of falls. Secondary outcomes included fall-related injuries, leg strength (1 repetition maximum; kg), and balance (sensory organization [equilibrium score] and limits of stability [LOS; %] tests). RESULTS: Four hundred sixty-two women were enrolled (mean age, 62 ± 6.3 years). Retention was 93%, and adherence averaged 72.9%. In primary analysis, there was no difference in the incidence of falls between groups after 6 months of training, nor during 6-month follow-up. A post hoc analysis detected a significantly reduced incidence of fall-related injuries within the tai ji quan group over the first 6 months, dropping from 4.3 falls per 100 person-months (95% CI, 2.9 to 5.6) at baseline to 2.4 falls per person-months (95% CI, 1.2 to 3.5). No significant changes occurred during 6-month follow-up. Over the intervention period, leg strength significantly improved in the strength group and balance (LOS) improved in the tai ji quan group, compared with controls (P < .05). CONCLUSION: We found no significant reduction in falls for tai ji quan or strength training relative to stretching control in postmenopausal women treated with chemotherapy.

RESUMEN

Among married couples living with breast and prostate cancer, positive perceptions of relationship quality by both survivors and their spouses were associated with lower inflammation or insulin resistance in their partner. Our data support evidence that health within couples is both interdependent and transactional and suggests that one member's perception of the relationship is associated with biologic changes in one's partner, leading to better physical health of the couple. These findings may provide a biologic underpinning to observations of an inverse relationship between relational satisfaction and overall mortality and underscore the need for a dyadic approach to health. PURPOSE: Couples' health and health behaviors are intertwined, where the health of one partner can influence the health of the other but the biologic underpinnings are not known. We examined the associations between relational health and markers of inflammation and insulin resistance in couples coping with breast or prostate cancer. METHODS: Participants (90 cancer survivor-spouse dyads) completed self-report measures of relational health including Dyadic Adjustment Scale-7 (relationship quality), Dyadic Coping Inventory (communication), and shared physical activity, as well as Community Health Activities Model Program for Seniors (individual physical activity). Inflammation (C-reactive protein (CRP)) and homeostasis model assessment of insulin resistance (HOMA-IR) were measured in serum samples. Structural equation modeling including demographic and clinical covariate controls was used to estimate separate actor and partner effects of relationship quality, communication, and physical activity on CRP and HOMA-IR. RESULTS: Participants were aged 63.1 ± 10.4 years with an average relationship duration of 30.0 ± 1.1 years. Higher survivor perceived relationship quality was associated with lower spouse CRP (b = - 0.07; 95%CI: - 0.13, - 0.01), whereas higher spouse perceived relationship quality was associated with lower survivor HOMA-IR (b = - 0.07; 95%CI: - 0.13, - 0.03). There were no other significant actor or partner effects observed. CONCLUSIONS: Among cancer survivor-spouse dyads, how one member of the couple perceives the quality of the relationship impacts disease biomarkers in the other, providing preliminary evidence for biological linkage between relational health and chronic disease risk. IMPLICATIONS FOR CANCER SURVIVORS: Relationship quality may positively influence biomarkers of inflammation and insulin resistance in couples coping with breast and prostate cancer. Dyadic approaches to optimize survivorship health may be warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT03630354, 08/14/2018; Open Science Framework ( https://bit.ly/3S4rUtJ ).

RESUMEN

PURPOSE: To evaluate the effects of 24 weeks of Mat Pilates in breast cancer survivors (BCS) undergoing hormone therapy on lower and upper body muscle strength parameters and flexibility. MATERIALS AND METHODS: Forty-three BCS (≥40 years) with confirmed breast cancer stage 0-III undergoing hormone therapy were included. Participants were randomized into Mat Pilates (three times/week, 60 min session) or control group (relaxation activities every two weeks). The difficulty and number of exercise repetitions were increased over the weeks. Assessments were performed at three times points (baseline, 12 weeks, and 24 weeks). The generalized estimating equations (GEE) model was used to compare each outcome measure during the analysis of intention to treat (ITT) and "Per protocol analysis" (PPA). RESULTS: The Pilates group presented significantly increased (p < 0.05) isometric flexor-extensor PT, and concentric and eccentric flexor PT and mechanical work (MW) after the intervention. Most of the upper body strength parameters, time to achieve maximal force (TFmax), maximal force (Fmax), and rapid force index (RFI) and right-left upper and lower body flexibility (p < 0.05) also improved. CONCLUSIONS: From our findings, we conclude that 24 and 12-weeks of Mat Pilates induced strength and flexibility gains for lower and upper body, respectively.Implications for rehabilitationMat Pilates can be adapted to the fitness level of breast cancer survivors, with a great variety of exercises that can be performed using a mat only or a few pieces of equipment.Patients can practice at home to gain different health benefits (i.e., increasing strength, flexibility, and functional capacity level), which could positively impact on quality of life.Mat Pilates performed three times per week with systematized increments in exercise level, load, and volume throughout the intervention was effective to improve hip extensor-flexor muscles peak torque and mechanical work at different muscle contractions, as well as upper and lower body flexibility.Mat Pilates was also able to improve right-left shoulder abductor and trunk extensor muscles strength parameters after 12 weeks of intervention, as well as both surgery and non-surgery sides of the upper body.

RESUMEN

BACKGROUND: Following a prostate cancer (PC) diagnosis, treatment-related symptoms may result in diminished quality of life (QoL). Improved diet and increased exercise may improve QoL in men with PC. METHODS: We conducted a 4-arm pilot randomized trial to assess feasibility and acceptability of a 3-month web-based diet and exercise intervention, among men (>18 years of age) with PC (reported elsewhere). The purpose of this study is to describe the change in QoL measured by surveys (eg, QLQ-C30, PROMIS Fatigue) at enrollment and following the intervention. Men were randomized 1:1:1:1 to increasing levels of web-based behavioral support: Level 1: website; Level 2: Level 1 plus personalized diet and exercise prescription; Level 3: Levels 1-2 plus Fitbit and text messages; Level 4: Levels 1-3 plus 2 30-minute coaching calls. T-tests were used to compare pre-post change in mean QoL scores between each Level and Level 1. RESULTS: Two hundred and two men consented and were randomized (n = 49, 51, 50, 52 for Levels 1-4, respectively). Men were predominantly white (93%), with a median age of 70 years (Intra-quartile Range [IQR]: 65,75) and 3 years (IQR: 1,9) post primary treatment for mostly localized disease (74% with T1-2). There were no meaningful changes in QoL, but there were notable trends. Level 3 participants had small improvements in QLQ-C30 Global Health (5.46; 95% CI: -0.02, 10.95) compared to Level 1. In contrast, Level 2 participants trended toward decreasing Global QoL (-2.31, 95% CI: -8.05, 3.42), which may reflect declines in function (eg, Cognitive: -6.94, 95% CI: -13.76, -0.13) and higher symptom burden (eg, Diarrhea: 4.63, 95% CI: -1.48, 10.74). CONCLUSIONS: This short, web-based intervention did not appear to have an impact on PC survivors' QoL. Most men were several years past treatment for localized disease; the potential for this approach to reduce symptoms and improve QoL in men who have worse health may still be warranted.

RESUMEN

OBJECTIVES: To assess the reliability of using videoconference technology to remotely administer the Short Physical Performance Battery (SPPB), including the 5-time sit-to-stand (5XSTS) and usual 4-m walk (4mWT), and the Timed Up and Go (TUG) tests and agreement with in-person administration among adults with and without cancer. METHODS: Participants from two ongoing clinical exercise trials in cancer survivors, one that included partners without cancer, comprised the available sample (n = 176; mean age 62.5 ± 11.5 years.). Remote tests were administered on two separate days by either the same or a different assessor to determine intra-rater and inter-rater reliability, respectively. We also compared tests conducted remotely and in-person using the same assessor and the same participant. Intraclass correlation coefficients (ICC) and 95% confidence intervals (95% CI) were used for all comparisons, except for the SPPB score, which used Cohen's kappa and Krippendorf's alpha for intra- and inter-rater reliability, respectively. RESULTS: Remote assessment of the TUG test had excellent intra-rater reliability (0.98, 95% CI 0.93-0.99), inter-rater reliability (ICC = 0.96, 95% CI 0.90-0.99), and good agreement with in-person tests (ICC = 0.88, 95% CI 0.74-0.94). The 5XSTS and 4mWT showed excellent (ICC = 0.92, 95% CI 0.84-0.96) and good (ICC = 0.87, 95% CI 0.71-0.94) intra-rater reliability, respectively, but somewhat lower inter-rater reliability (5XSTS: ICC = 0.65, 95% CI 0.34-0.83 and 4mWT: ICC = 0.62, 95% CI 0.30-0.81). Remote 5XSTS had moderate agreement (ICC = 0.72, 95% CI 0.62-0.80) and 4mWT had poor agreement (ICC = 0.48, 95% CI -0.07-0.76) with in-person tests. CONCLUSIONS: Remote assessment of common physical function tests in older adults, including those who have cancer, is feasible and highly reliable when using the same assessor. TUG may be the most methodologically robust measure for remote assessment because it is also highly reliable when using different assessors and correlates strongly with in-person testing. Adapting administration of objective measures of physical function for the remote environment could significantly expand the reach of research and clinical practice to assess populations at risk of functional decline.

RESUMEN

PURPOSE: Exercise has been underutilized in people with advanced or incurable cancer despite the potential to improve physical function and reduce psychosocial morbidity, especially for people with bone metastases because of concerns over skeletal complications. The International Bone Metastases Exercise Working Group (IBMEWG) was formed to develop best practice recommendations for exercise programming for people with bone metastases on the basis of published research, clinical experience, and expert opinion. METHODS: The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to review evidence from steps 1-3 to develop draft recommendations, and (5) stakeholder engagement. RESULTS: Recommendations emerged from the contributing evidence and IBMEWG discussion for pre-exercise screening, exercise testing, exercise prescription, and monitoring of exercise response. Identification of individuals who are potentially at higher risk of exercise-related skeletal complication is a complex interplay of these factors: (1) lesion-related, (2) cancer and cancer treatment-related, and (3) the person-related. Exercise assessment and prescription requires consideration of the location and presentation of bone lesion(s) and should be delivered by qualified exercise professionals with oncology education and exercise prescription experience. Emphasis on postural alignment, controlled movement, and proper technique is essential. CONCLUSION: Ultimately, the perceived risk of skeletal complications should be weighed against potential health benefits on the basis of consultation between the person, health care team, and exercise professionals. These recommendations provide an initial framework to improve the integration of exercise programming into clinical care for people with bone metastases.

RESUMEN

BACKGROUND: Because of the COVID-19 pandemic, our research team quickly pivoted from planned face-to-face interaction with participants to virtual interactions. During this transition, we discovered invaluable new practices for conducting research remotely, including collecting physiological data. OBJECTIVE: Our objective was to describe the methodological challenges we encountered when conducting this research virtually with grandparent-grandchild dyads and describe the strategies we developed to overcome those challenges. Of primary focus were procedures for finger-stick blood sample collection. Of secondary focus were procedures for conducting virtual-based research with older adults and across multiple generations. METHODS: During an observational study utilizing a virtual platform with 11 grandparent-grandchild dyads (mean age: 64.2 ± 5.0 years for grandparents and 9.3 ± 1.9 years for grandchildren), we documented lessons learned (based on the discussion within our team and feedback we have received from participants) that could be applicable for other, similar research endeavors. RESULTS: We found several challenges in collecting blood samples, including staff were unfamiliar with providing online instruction and participants needed to develop familiarity with the blood sample collection process (without having in-person assistance), and we had to develop methods for delivering blood sample collection kits to participants safely. We also found that it took longer than expected to run procedures-a challenge that might be encountered when conducting any type of dyadic research utilizing a virtual platform-particularly involving older adults and across multiple generations. In addition, it was challenging to keep child participants engaged in the virtual interactions. We document how we employed targeted strategies to overcome those obstacles. Recommendations for strategies from our team include to provide comprehensive and clear instruction/materials on blood sampling procedure, offer generous support throughout the blood collection process, be prepared to divide study visits into more than one session as needed, proactively anticipate potential roadblocks, and carefully consider the participants' developmental stages and attention span. DISCUSSION: The insights we gained will help inform future research with grandparent-grandchild dyads in remote or rural populations utilizing virtual platforms.

RESUMEN

ObjectiveOver one-third of college students are overweight or obese and rates are rising. Whole body vibration (WBV) training could prevent weight gain but has not been tested in college students. Methods: Randomized controlled trial comparing thrice weekly WBV for 6 months to controls (CON) in undergraduate students. Feasibility included retention, adherence and safety and outcomes included changes in weight, body mass index (BMI) and fat mass. Results: 77 students enrolled in the trial (WBV: n = 40, CON: n = 37), 81% completed the study. Adherence to WBV averaged 59%. Average group differences were 1% body fat (p = 0.049) and 1 kg fat mass (p < 0.01), favoring WBV. Among students completing >80% of prescribed WBV sessions significant group differences widened, while group differences in BMI (p = 0.026) and weight (p = 0.02) change became significant. Conclusions: WBV may be a feasible, safe and effective approach to weight management in college students, though strategies to optimize adherence should continue.

RESUMEN

PURPOSE: Due to stay-at-home orders during COVID-19, we transitioned supervised, group, in-person resistance training interventions in two clinical trials in cancer survivors to live, online delivery using video-conferencing technology. We describe the feasibility, preliminary efficacy, and safety of live online group training and compare to in-person training. METHODS: Adherence (% sessions attended), retention (% participants completing intervention), and safety (# adverse events) data of resistance training groups from two randomized controlled trials in cancer survivors that participated before or during the COVID-19 pandemic were collated. Participants were post-treatment breast cancer survivors and their spouses (n = 62) and prostate cancer survivors (n = 32) (age range: 38-82 years). During COVID-19, delivery of supervised, group resistance exercise sessions was delivered live online via video-conference. Preliminary evidence for training efficacy was assessed by chair stand performance over the 6-month intervention. RESULTS: Feasibility of online resistance training was better than in-person for both studies (adherence: 86% vs 82% and 91% vs. 81% and retention 95% vs. 80% and 92% vs. 84% for online and in-person classes). Improvements in chair stand time were similar in prostate cancer and spouse groups that trained online vs. in-person, except for breast cancer survivors who improved more with in-person training (7% vs. 14% for online vs. in-person). Safety was similar between formats (12 vs. 11 adverse events for online vs. in-person). CONCLUSION: Supervised, in-person group resistance training can be feasibly adapted for live, online delivery and could help broaden approaches to exercise delivery in cancer survivors, including older adults. TRIAL REGISTRATION: The studies described in this commentary were registered on ClinicalTrials.gov on August 3, 2018 (NCT03630354) and on October 30, 2018 (NCT03741335).
