Impact of Amino Acids to Enhance Anabolism After Home-based Exercise

An adequate quantity of lean body mass is vital for optimal health and performance, and is accrued when net protein balance (NPB) is positive. Amino acids are the building blocks of protein, and when consumed following resistance exercise, significantly improve NPB. However, no study has investigated how a supplement of all of the essential amino acids (EAA) affects NPB following resistance exercise in a free-living, home-based setting, particularly when compared to a supplement of branched-chain amino acids (BCAA). Therefore, the purpose of this study is to determine the impact of a novel EAA supplement on anabolism (e.g., NPB) as compared to BCAA and placebo supplements following home-based resistance exercise.

Feasibility of a Novel, Theory Based Physical Activity Intervention Among Adult Cancer Survivors

As the number of cancer survivors grows and expected survival time increases, the health behaviors of this population are gaining significant attention from the research and public health community. Adoption or maintenance of healthy lifestyles after cancer has the potential to reduce both cancer- and non-cancer-related morbidity and mortality. Exercise adoption and maintenance remains a significant challenge for adults, especially clinical populations such as cancer survivors who may struggle with comorbidities, symptoms and side-effects of the disease or medications, and overall compromised health and functioning. A number of site-based exercise interventions have been conducted to promote physical activity, often using a theoretical basis to design and execute the intervention. Although these programs are successful in exposing cancer survivors to regular physical activity, they often struggle with exercise maintenance after the conclusion of the structured site-based group exercise sessions. The goal of the proposed project is to enhance physical activity engagement among adult cancer survivors by designing a home-based program using the socio-ecological framework and employing constructs from social cognitive theory to guide participants through the project.

Effect of Individualized Training Versus Non-individualized Training to Improve Quality of Life of Sedentary Employees

The practice of a physical activity, even moderate, plays an important role in the prevention and the management of the main chronic non-communicable diseases (cardiovascular diseases, certain cancers, diabetes, obesity, osteoporosis ...) as well as by improving psychological health. Several studies have shown that physical activity has a positive impact on the economy of companies via the reduction of absenteeism and the improvement of productivity. However, it seems important to individualize these recommendations in order to prescribe the best possible dose of physical activity for each individual. In this project, the investigators want to test the physical qualities of employees in order to prescribe the best possible dose of physical activity with the ultimate goal of improving quality of life.

Correlation Between HRV and Performance in Eccentric Resistance Training Associated With Partial Blood Flow Restriction

Studies on resistance training (RT) associated with blood flow restriction (BFR) is an alternative method of gaining strength and hypertrophy muscle. However, there is a gap correlated to autonomic repercussion of BFR and performance. Thus, it becomes relevant to investigate this type of training in post-exercise. Objective: investigate and compare autonomic and performance responses of 6 weeks of eccentric RT with different intensities associated or not to BFR in healthy youngsters. Method: This is a randomized clinical trial including 60 healthy men aged 18-35 years, divided into four groups according to exercise intensity and BFR: 80% without BFR, 40% without BFR, 80% with BFR and 40% with BFR. Exercise intensity will be determined by the peak of excentric torque on the isokinetic dynamometry method and by the BFR, as being 40% of the intensity required for the complete examination of the blood flow evaluated by Doppler. Participants will do an eccentric femoral quadriceps muscle exercise session on the isokinetic dynamometer according to the previously randomized group. For recovery analyzes, it will be used: the root-mean-square of the successive normal sinus RR interval difference (rMSSD); high frequency (HF) ms²; HF(nu) and the standard deviation of instantaneous beat-to-beat interval variability (SD1). For performance, it will be used the single leg hop test. For data analysis of the population profile, the descriptive statistical method will be used and the results will be presented with values of means, standard deviations, median and confidence interval. Initially, participants from all study groups will be dichotomized at each performance outcome (muscle strength test on the isokinetic dynamometer and vertical jump test) as "improvement" or "without improvement" in order to demonstrate the behavior of the responses obtained during the training, that is, whether the individual responded to the RT or not. It is worth mentioning that this qualitative analysis will be performed considering the data obtained from the initial, intermediate and final evaluation. The dichotomization of the results of the functional tests will be performed by the typical error of the sample measurement for each test. It will be considered as "improvement" if the participant presents gains in tests above the typical error of the measure. The values obtained from the initial, intermediate and final evaluation will be analyzed independently. Subsequently, the weekly average of the vagal indices (rMSSD, HF and SD1) will be performed in the baseline moment and after 6 weeks of RT moment of each study group. In the sequence, the performance parameters will be correlated with the autonomic parameters in the respective groups. Pearson or Spearman correlation test will be used according to the normality of the data. The level of significance will be p <0.05 for all tests. The statistical program SPSS (Statistical Package for the Social Sciences) will be used for the analyzes.

Multiphase Optimization Trial of Incentives for Veterans to Encourage Walking

Regular physical activity (PA) is essential to healthy aging. Unfortunately, only 5% of US adults meet guideline of 150 minutes of moderate exercise; Veterans and non-Veterans have similar levels of PA. A patient incentive program for PA may help. Behavioral economics suggests that the chronic inability to start and maintain a PA routine may be the result of "present bias," which is a tendency to value immediate rewards over rewards in the future. With present bias, it is always better to exercise tomorrow because the immediate gratification of watching television or surfing the internet is a more powerful motivator than the intangible and delayed benefit of future health. Patient incentives may overcome present bias by moving the rewards for exercise forward in time. Recent randomized trials suggest that incentives for PA can be effective, but substantial gaps in knowledge prevent the implementation of a PA incentive program in Veterans Affairs (VA). First, incentive designs vary considerably. They vary by the size of the incentive, the type of incentive (cash or non-financial), the probability of earning an incentive (an assured payment for effort or a lottery-based incentive), or whether the incentive is earned after the effort is given (a gain-framed incentive) or awarded up-front and lost if the effort is not given (a loss-framed incentive). The optimal combination of these components for a Veteran population is unknown. Second, the evidence about the effective components of incentives comes from studies conducted in populations that were overwhelmingly female; often employees at large companies, with high levels of education and income. VA users, in contrast, are mostly male and lower income, and most are not employed. This is important because the investigators have theoretical reasons to believe that the effects of components of incentives are likely to vary by income and gender. Finally, few studies have managed to design an incentive such that the physical activity was maintained after the incentive was removed. Indeed, a common theme in incentivizing health behavior change is the difficulty in sustaining behavior change once the incentives are removed.

Conmigo: A Mother-daughter Intervention to Promote Physical Activity

Regular physical activity (PA) contributes to reduced risk of obesity, chronic disease, cardiovascular disease, and cancer, and can improve emotional and mental health, learning, productivity, and social skills. Latina girls are less likely to meet guidelines for moderate-to-vigorous physical activity (MVPA) than non-Hispanic white girls; factors that contribute to low PA rates among Latina girls include sex role expectations, low PA competency, few active role models, lack of parental support for PA, and lack of access to resources. The goal of this study, informed by social cognitive theory and family systems theory, is to design, implement, and evaluate an intervention promoting physical activity among Latina pre-adolescent girls (aged 8-11) and their mothers. The intervention is based on evidence suggesting that parent-child interventions and single-sex interventions are more effective at improving PA. Mothers and daughters will participate in a 12-week virtual intervention where they will engage in weekly 1.5-hour sessions that incorporate didactic teaching, skill-building, interactive discussions, and PA. Each session will include at least 30 minutes of PA. The intervention will be compared with a control condition that will receive an abbreviated version of the intervention following completion of all measurement points. Ninety mother-daughter dyads will be randomly assigned to the intervention or the wait-list control condition. The primary aim is to determine whether the intervention will increase MVPA among Latina girls in the intervention condition relative to those in the control condition. The investigators hypothesize that daughters participating in Conmigo will have higher minutes of MVPA at M2 and M3 compared to girls in the delayed treatment control condition.

RaceRunning for Young People With Moderate-to-severe Cerebral Palsy

Physical inactivity in people with cerebral palsy (CP) has been linked with increased risk of cardiometabolic disease. Exercise studies rarely include people with CP with severe walking impairments and assess the sustainability of the intervention. RaceRunning allows people severe walking impairments to independently propel themselves using a running bike, which has a breast plate for support but no pedals. This project will assess the feasibility of at trial into the effectiveness of RaceRunning to reduce cardiometabolic disease risk factors and improve functional mobility. Intervention: Weekly standardised RaceRunning sessions over 6 months led by an experienced coach. Participants Twenty-five young people with CP aged 5-21, GMFCS levels III-V. Feasibility outcomes: Acceptability of RaceRunning, adherence and fidelity of the intervention, recruitment and retention rates and adverse events. Outcome measures: Cardiometabolic disease risk factors (physical activity, sedentary time, resting heart rate and blood pressure and aerobic capacity) and functional mobility assessed at baseline, 3 and 6 months. Quality of life (EQ-5D-Y) and health service use will inform a future cost-effectiveness analysis. Aspects of feasibility and acceptability and the variability and patterns of the change in outcomes will be reported using descriptive statistics.

Dynamic Proteomics and Integrated Rates of Muscle Protein Synthesis During an Acute Period of Loading and Unloading

Skeletal muscle plays several different roles in the promotion and maintenance of health and well-being. The loss of muscle mass that occurs with aging, chronic muscle wasting diseases, and physical inactivity puts people at an increased risk of frailty and becoming insulin resistant, and therefore imposes a significant burden on health care spending. Resistance exercise participation has proven particularly effective for increasing muscle mass and strength. This effectiveness can be used by health care practitioners in a rehabilitation setting to promote the recovery of individuals who have undergone involuntary periods of muscular unloading (i.e. limb immobilization caused by a sports injury or reconstructive surgery). However, there is large variability in the amount of muscle mass and strength that people gain following participation in resistance exercise. Some individuals fail to increase the size of their muscle (low responders) whereas others show vary large increases in muscle size (high responders) in response to the same resistance training program. People also show differences in the amount of muscle tissue they lose when they have a limb immobilized. To circumvent variability across individuals, the investigators utilized a within-person paired Hypertrophy and Atrophy ('HYPAT') strategy that reduced response heterogeneity by ~40% (Available at: https://ssrn.com/abstract=3445673). Specifically, one leg performed resistance training for 10 weeks to induce hypertrophy, whereas the other leg underwent single-leg immobilization for 2 weeks to induce atrophy. The primary goal of the study will be to gain insight into the molecular responses to an acute period of single-leg immobilization and resistance exercise (8 days). The investigators will use an integrated systems biology approach to monitor the individual rates of over one hundred different muscle proteins.
