In this study, we will randomly assign 360 older adults to 12 months of 5 minutes per day of functional resistance training or to a delayed treatment control condition, and measure the impact of the training on measures of lower extremity performance and walking ability.
This randomized crossover study will examine the effects of consuming isocaloric GLU+FRU or GLU alone on rates of exogenous carbohydrate oxidation during aerobic exercise and physical performance (time trial) under energy balance (BAL) and energy deficit (DEF). Baseline data will be collected on volunteer height, weight, body composition, and V̇O2peak. To ensure volunteers are familiar with exercise protocols, they will complete practice sessions of all exercise before the start of data collection. Exercise and diet will be controlled throughout data collection. To start the protocol volunteers will complete a bout of glycogen normalization on a cycle ergometer followed by 48 hours of refeeding at 100% (BAL) or 50% (DEF) of their energy needs. After the 48 hours of refeeding volunteers will return to the laboratory to complete 80 min of steady-state (60 ± 5% V̇O2peak) exercise on a cycle ergometer. Immediately before and during steady-state exercise, volunteers will consume either 80 g of GLU+FRU (53 g glucose + 27 g fructose) or 80 g GLU. Drinks containing corn-derived crystalline fructose (KRYSTAR® 300, Tate and Lyle Sugars, London, UK) and glucose (CERELOSE®, Ingredion, Westchester, IL, USA) will be prepared by unblinded USARIEM staff. Drinks will be enriched with 13C stable isotopes (Cambridge Isotope Laboratory, Andover, MA, USA) to measure exogenous and plasma carbohydrate oxidation during steady-state exercise. After steady-state exercise, physical performance will be assessed using a graded exercise test on a stationary bike. Indirect calorimetry and breath sampling will be used to determine substrate oxidation during steady-state exercise. Serial blood draws will be collected during each trial to assess isotope enrichments, and circulating substrate/hormone responses. Muscle biopsies will be performed before and after steady-state exercise to assess glycogen status, enzyme activity, and molecular regulation of substrate metabolism. There will be a minimum of 7 days between each carbohydrate metabolism study day.
The goal of this randomized clinical trial is to determine the effects of consuming the Close Combat Assault Ration (CCAR) compared to the First Strike Ration (FSR) during a 7-day strenuous military training on energy intake and energy balance in healthy, Active Duty Warfighters. The main questions it aims to answer are: * Will consuming the CCAR result in lower energy intake or energy balance compared to consumption of the FSR? * Will consuming the CCAR result in lower lower body strength or anaerobic power compared to consuming the FSR? * Will those consuming the CCAR report lower ration acceptability or greater gastrointestinal side effects compared to those consuming the FSR? Participants will be asked to consume either the CCAR or FSR as the sole nutrition source during a 7-day field training exercise (FTX). The vertical jump test, running-based anaerobic sprint test, and lower-body strength pull will be conducted pre and post the 7-day FTX to assess physical performance. Energy expenditure and intake will be measured by the doubly-labelled water method and dietary logs, respectively. Surveys will be completed to assess ration acceptability and gastrointestinal symptoms. Researchers will compare the CCAR and FSR groups to see if their consumption impacted energy intake, energy balance, physical performance, ration acceptance, or gastrointestinal side effects.
The COcoa Supplement and Multivitamin Outcomes Study (COSMOS; NCT02422745) is a randomized clinical trial of cocoa extract supplement (containing a total of 500 mg/d flavanols, including 80 mg. (-)-epicatechins), and a standard multivitamin supplement to reduce the risk of cardiovascular disease and cancer among men aged 60 years and older and women aged 65 years and older. This ancillary study is being conducted among participants in COSMOS and will examine whether the cocoa extract supplement or the multivitamin supplement improve musculoskeletal health and prevent falls and declining physical performance in the increasing number of older adults in the U.S. with potential for clinical and public health benefits.
Negative hematological adaptations due to prolonged periods of strenuous physical activity may, in part, contribute to declines in physical performance during military operations. Exogenous erythropoietin (EPO) is a potential intervention that may be used to maintain hemoglobin (hgb), hematocrit (Hct), and physical performance during periods of high physical activity. The objective of the current study is to determine the ability of EPO to maintain hgb, Hct, and physical performance compared to baseline measures. Additionally, EPO may result in non-hematological adaptations which increase mitochondria biogenesis and alter substrate oxidation. As such, this study will also assess the influence of EPO on whole-body and skeletal muscle substrate oxidation. Eight healthy physically active individuals will be recruited to participate in this longitudinal trial. After exercise practice sessions, volunteers will complete baseline physical performance (time trial) and substrate oxidation testing. Participants will then receive EPO injections 3 times per week for 4 weeks. Diet and exercise will be controlled during the injection period. Participants will undergo four weeks of an intense physical training exercise program. Every seventh day during the injection period a safety blood sample, assessing hematocrit, will be drawn, and participants will complete a 5 km time trial to determine the time course of changes in physical performance can be detected. After the 4 weeks of EPO injections volunteers will complete the same physical performance and substrate oxidation testing. Substrate oxidation will be assessed during 90-min steady-state load carriage (30% body mass) exercise on a treadmill at 55 ± 5% of VO2peak. 6-6-\[2H2\] glucose tracer technique and indirect calorimetry will be used measure substrate oxidation. Muscle biopsies will be performed to measure muscle glycogen, enzyme activity, and molecular markers of metabolism and inflammation before, and immediately and 3-hrs post exercise. Multiple blood samples will be collected throughout the study to determine alterations in hemoglobin, hematocrit, and markers of substrate metabolism, and inflammation. All study procedures will occur at USARIEM. The primary risks associated with this study include those associated with EPO injection, exercise, blood draws, and muscle biopsies.
The purpose of this study is to examine the pre, post, and follow up effects of a single ZILRETTA knee injection vs a single CELESTONE SOLUSPAN knee injection on physiological measure of self-reported quality of life, pain, physical function, and physical performance in individuals with osteoarthritis (OA) knee pain. The Primary Investigator (PI) will recruit 20 symptomatic knee OA patients for this study. Patients will be randomized into one of two treatment arms, Arm 1 (ZILRETTA injection) or Arm 2 (CELESTONE SOLUSPAN injection). Patients in Arm 1 will receive a single 5 mL IV injection of 32 mg ZILRETTA into the affected knee joint. Patients in Arm 2 will receive a 5ml IV injection of 6mg/ml CELESTONE SOLUSPAN into the affected knee joint. Each study arm will include 10 patients. All data will be collected prior to injection (baseline), as well as at 6-week (post 1) and 12-week follow-ups (post 2). Patients will blinded to treatment arm until after they complete their 12-week follow up.
The main purpose of this research study is to determine if exercise improve or worsen cachexia.
Investigators specific aims are to compare the effects of consuming daily snacks of raw, shelled, unsalted almonds (2.0 ounces) versus an isocaloric amount of another commonly consumed snack food (pretzels) on energy (vigor) perception and physical activity, exercise performance (VO2max and measures of strength), strength and power performance as well as muscle soreness recovery after strenuous eccentrically-biased exercise.
The objective of this randomized crossover study is to examine the influence of consuming a ketone ester plus carbohydrate (KE+CHO) supplement on substrate oxidation and physical performance in 15 healthy adults. Following a 48-hr muscle glycogen normalization period, volunteers will consume either an isocaloric KE+CHO (KE: 573 mg KE/kg body mass, CHO: 110 g) or isocaloric CHO drink and complete 90-min of metabolically-matched, load carriage (\~30% body mass) steady-state aerobic (\~60 ± 5 % of VO2peak) exercise on a treadmill. Glucose tracers will be used to assess glucose turnover, and contribution to exogenous and plasma glucose oxidation. Serial blood draws will be collected during each trial to assess endocrine and circulating substrate responses. After steady-state exercise volunteers will complete a time to exhaustion (TTE) physical performance tests at 85% VO2peak on a treadmill. Volunteers will then be provided with food for the remainder of the day. Following a 10-hr overnight fast, volunteers will return to the laboratory and consume the same supplement (KE+CHO or CHO) as they did the previous day. Volunteers will then perform a 4-mile load carriage time trial on a treadmill. Following a minimum 7-day washout period, volunteers will return to the laboratory to complete the second arm of the study. The primary risks associated with this study include those associated with exercise, blood draws, and gastrointestinal discomfort from the KE+CHO supplement.
Red Spinach is a natural food which is a rich source of nitrates, which are beneficial in hemodynamics, cardiovascular function, and have natural hypotensive and antianginal effects . In recent research, Red spinach extract has been shown to be beneficial in acute exercise performance. However, currently it is unclear how these acute increases in performance may translate to long term training adaptations. This research study is designed to measure the effects of red spinach extract (RSE) on markers of physical performance, body composition, and health following chronic resistance training and anaerobic exercise.

The purpose of this study is to compare vitamin D deficient and vitamin D sufficient elderly individuals and examine the effect of a vitamin D dietary supplement on serum vitamin D level, bone formation, resorption, and mineral density, flexibility, balance, general inflammation,and quality of life. Enhancing nutritional status is necessary to prevent the continued proliferation of chronic diseases, e.g., bone disease and other chronic disorders thought to now be related to low levels of vitamin D, which are some of the leading disablers and killers of Americans. Americans also have difficulties with compliance to prescription medications due to their toxicity and side effects. This study aims to learn more about how a vitamin D nutritional supplement may improve nutritional status and enable the body to normalize system functioning,which may improve the quality of life for people with vitamin D deficiency. The results of this research will be used to determine if vitamin D is beneficial for overall health among elderly individuals.
The age-related loss of muscle mass and strength, also termed sarcopenia, is a commonly recognized consequence of aging and has been associated with frailty, functional loss, hospitalization, and increased mortality among older people. Sarcopenia and its consequences have a considerable economic impact, since it has been estimated that the healthcare cost attributable to sarcopenia in the US in 2000 was $ 18.5 billions. Preclinical animal models strongly suggest that apoptosis, a programmed cell death, might play a prominent role in the age-related muscle wasting. In specific aim one, the investigators will assess the extent of muscle apoptosis in muscle biopsies obtained from the vastus lateralis muscle of young control subjects (ages 20-35) and high-performance and low-performance older subjects (age range 70-99 years). In specific aim 2, the investigators will investigate the role of Poly (ADP-ribose) polymerase 1 (PARP-1) and apoptosis-inducing factor (AIF) in the induction of skeletal muscle apoptosis. In specific aim 3, the investigators propose to investigate the contribution of the muscle energy deficit, due to the age-related mitochondrial dysfunction, in the development of muscle wasting. Finally, in specific aim 4, the investigators propose to reassess after four years physical performance, muscle mass and the extent of muscle apoptosis, in the high-performing participants, in order to correlate eventual decline in physical function, muscle mass and functional status, with changes in muscle apoptosis and in biochemical parameters in this very old population. Physical performance will be established according to the summary performance score obtained in the Short Form Physical Performance Battery (SPPB). In addition to the SPPB the investigators will also employ hand grip strength and knee extensor strength tests and the investigators will quantify muscle contractile area using 3D magnetic resonance imaging. Disability will be assessed using a self-report questionnaire. These studies will enhance our understanding of the biology and pathophysiology underlying the geriatric syndrome of sarcopenia and provide significant and novel insights that will enable us to identify new potential targets for interventions aimed at preventing and treating sarcopenia and functional impairment in older adults.
Stroke, a leading cause of disability in the aging population, increases the risk for diabetes, subsequent stroke recurrence, and cardiovascular disease complications. The downsizing of private and federal health care resources, along with the anticipated increase in stroke rates as our population ages, mandate that alternative strategies be developed to reduce the public health burden of stroke. This pilot study may facilitate our knowledge of the timing of paretic leg muscle atrophy, fiber type shift, and the progression of worsening of glucose tolerance after stroke. Knowledge of the skeletal muscle changes occurring in the sub-acute stroke period is essential to create new guidelines incorporating exercise rehabilitation, much like cardiac rehabilitation, in order to facilitate and improve the health care of veteran stroke survivors.
The aim of the present study was to investigate the effects of soy and soy plus isoflavones on bone mineral Density and physical performance in post menopausal women.

The project is intended to modify the Functional Independence Measure (FIM) for manual wheelchair users. It will determine if the new measure is a better measure of community independence for manual wheelchair users than the FIM. During the Phase 1 of the study it will then use this new measure to determine whether a home exercise program increases functional independence in wheelchair users. In Phases II and III of the study 120 manual wheelchair users will participate to test and validate the new measure and to test the effectiveness of therapeutic exercise. Subjects will range in age from 20 to 79 yrs. and have a variety of disabilities.
Previous research has found improvements in performance (VO2max) and clinical (insulin resistance) with cycling REHIIT. In some populations (e.g. obese, arthritic) aquatic exercise is a safer, more enjoyable option. However, to date, no study has yet examined whether aquatic REHIIT confers the same benefits as land-based REHIIT. Therefore, the purpose of this study is to determine whether there are significant differences in clinical and performance outcomes between a land-based and comparable aquatics based Reduced Exertion High Intensity Interval Training (REHIIT) protocol.
Brain-Physical Optimization Conditioning (B-POC) aims to enhance physical performance by expanding the traditional focus of endurance training from purely physical training to the domain of cognitive endurance (Staiano et al., 2015; Dallaway et al., 2017). The current study seeks to isolate neurocognitive mechanisms of performance, particularly under high stress (e.g., physical or cognitive load) conditions, and to develop corresponding cognitive optimization tools.
Protein ingestion timing is an important component for muscle accretion. We hypothesized that protein ingestion timing could affect muscular adaptations and performance in resistance-trained men.
