Do Functional Movement Screens Predict Body Composition Changes after Resistance Training?

Although the function movement screen (FMS) has been widely used in the general population, no study to date has used the FMS as a preparticipation screen for individuals with breast cancer (BC) engaging in an exercise regimen. Even though individuals with BC are anthropometrically similar to individuals without cancer, the lack of studies assessing the FMS in individuals with BC may potentially hinder exercise prescription. Therefore, we aim to examine the relationships of the FMS score to anthropometric biomarkers in individuals with BC before undergoing an exercise regimen.

Agreement Between Bioelectrical Impedance Analysis and Ultrasound for Measuring Body Composition in Women with Breast Cancer.

Higher percent body fat (BF) is associated with worse outcomes after treatment for breast cancer (BC). While ultrasound (US) imaging is a reliable method for analyzing body composition, it requires trained individuals for utilization. As such, bioelectrical impedance analysis (BIA) has been suggested as an alternative.

Body Composition Benefits Diminish One Year After a Resistance Training Regimen in Breast Cancer Patients, Although Improvements in Strength, Balance, and Mobility Persist.

Objectives: Resistance training can improve body composition and physical function during and after breast cancer treatment and improve quality of life. It is unclear whether these changes persist once a person is no longer actively enrolled in a structured exercise regimen. Thus, we analyzed participants from the EXERT-BC protocol, assessing an intense exercise regimen in women with breast cancer at one year.

EXERT-BCN: An Exercise Regimen Designed to Improve Body Composition, Functional Capacity, and Strength After Treatment for Breast Cancer With Nutrition Optimization.

Purpose: Effective methods to improve body composition and metabolic/hormonal dysregulation are central to breast cancer care. We hypothesized that a nutrition regimen focused on food quality and an observed exercise regimen using high-load resistance training during or after cancer treatment would improve body composition and functional capacity.

Methods: Forty-four women with breast cancer, including survivors on therapy and in surveillance, excluding chemotherapy, underwent a continuously monitored dose-escalated exercise regimen utilizing heavy weights and linear progression in an exercise oncology facility along with a diet focused on food quality and adequate protein intake.

Grip strength as a surrogate measure of strength, functional, and metabolic parameter increases in breast cancer survivors undergoing an exercise regimen.

Grip strength, a surrogate for quantifying strength, correlates with function and longevity. However, this relationship is less clear in women with breast cancer. 138 women undergoing oncologic treatment for breast cancer were enrolled across three institutional review board-approved protocols with three months of resistance training with pre and post assessment of body composition, phase angle, functional movement screen (FMS), balance, weight lifted (load), quality of life, activity levels, and hand grip strength.

Single point insulin sensitivity estimator index for identifying metabolic syndrome in US adults: NHANES 2017-march 2020.

Purpose: Single Point Insulin Sensitivity Estimator (SPISE) index was recently introduced as a reliable indirect indicator of insulin resistance, applicable to large population-based research. Here, we aimed to 1) examine racial/ethnic differences in SPISE index among US adults, 2) compare predictive power of SPISE index for metabolic syndrome (MetSyn) by race/ethnicity, and 3) evaluate its predictive power for MetSyn against other well-known IR indices including Triglyceride/HDL-C, Triglyceride-glucose index, homeostatic model assessment for insulin resistance, and inverse fasting insulin.

Methods: A total of 2168 adults (814 white, 690 black, and 664 Hispanic) from NHANES 2017-March 2020 Pre-Pandemic Data was analyzed in this study.

Neuromuscular contributions to disability in children with cerebral palsy and the impact of dynamic stretching orthoses and therapeutic exercise interventions: a narrative review.

Background And Objective: Cerebral palsy (CP) is the most common motor disability in children. The initial lesion to the developing brain may result in a myriad of neuromuscular comorbidities, including mobility deficiencies. The neuromuscular contributions to disability and rehabilitative frameworks specific to children with CP have been investigated separately.

EXERT-BC: A pilot study of an exercise regimen designed to improve functional mobility, body composition, and strength after the treatment for breast cancer.

Purpose: Resistance training may offer several unique advantages within breast cancer (BC) survivorship care; however, safety concerns have limited the application of high-intensity compound movements necessary to elicit optimal changes in body composition, strength, and quality of life in this population. The EXERT-BC trial assesses the safety and feasibility of an evidence-based, dose-escalated resistance training regimen among BC survivors, with the goal of improving physical and metabolic function, mobility, muscle mass, and body composition.

Methods: Participants included women with breast cancer underwent a 3-month thrice weekly exercise regimen involving dose escalation of high-intensity compound exercises.

EXERT-BC: Prospective Study of an Exercise Regimen After Treatment for Breast Cancer.

EXERT-BC is a dose-escalated resistance training regimen created to improve body composition, strength, and balance in women treated for breast cancer (BC). Herein, we report the interim analysis. Women treated for BC underwent this 3-month exercise regimen in an exercise oncology facility with continual monitoring of load and strength.

Resistance Training for Patients with Cancer: A Conceptual Framework for Maximizing Strength, Power, Functional Mobility, and Body Composition to Optimize Health and Outcomes.

There are many benefits to the addition of exercise to cancer treatment and survivorship, particularly with resistance training regimens that target hypertrophy, bone mineral density, strength, functional mobility, and body composition. These goals are best achieved through a series of individualized high-intensity compound movements that mirror functional mobility patterns and sufficiently stress the musculoskeletal system. As a result of adequate stress, the body will engage compensatory cellular mechanisms that improve the structural integrity of bones and muscles, stimulate metabolism and the immune system, optimize functional performance, and minimize mechanical injury risk.

Metabolic syndrome: Operational definitions and aerobic and resistance training benefits on physical and metabolic health in children and adolescents.

Background: The variation in parameters for childhood metabolic syndrome (MetS) has hindered the development of a consensus for the diagnostic criteria in this group. Despite these inconsistencies, it is accepted that exercise can ameliorate the deleterious effects of MetS. However, direct comparison between aerobic versus resistance exercise on MetS symptomology in adolescents is lacking.

Incretin Hormones: Pathophysiological Risk Factors and Potential Targets for Type 2 Diabetes.

Type 2 diabetes (T2D) is a multifaceted metabolic disorder associated with distinctive pathophysiological disturbances. One of the pathophysiological risk factors observed in T2D is dysregulation of the incretin hormones, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). Both hormones stimulate insulin secretion by acting postprandially on pancreatic β-cell receptors.

Quantity of Resistance Exercise for Breast Cancer Patients: Does the Dose Match the Objective?

Rosenberg, J, Hyde, PN, Yancy, WS, Ford, KM, and Champ, CE. Quantity of resistance exercise for breast cancer patients: does the dose match the objective? J Strength Cond Res 35(5): 1467-1476, 2021-There is currently a lack of consensus as to what defines exercise and resistance training in the cancer setting and whether current studies comply with exercise guidelines. This study aimed to quantify the available research studies using resistance training exercise interventions in the breast cancer setting for future clinical trial utilization.
