The objective here is to assess the efficacy of variable resistance muscle training on bone, sleep parameters and quality of life in healthy populations of men and women age 30 or older.
A pilot study investigating whether heavy resistance training is enjoyable, acceptable, and feasible for middle-aged women undergoing the menopausal transition. Additional outcomes to be assessed include changes to strength and muscle composition as well as changes to cognitive function and self-reported measures of fatigue, cognition, self-efficacy, and mood.
Parkinson disease is a degenerative neurologic condition characterized by slowness of movement, tremor, and loss of balance control. It results in significant degrees of disability for affected individuals. Exercise and medication management are two treatments frequently used to treat Parkinson disease, and although some individuals benefit from these treatments, by what effect exercise works is presently not known. We will examine muscle structure and movement control responses to strengthening exercises and compare them to the therapeutic response observed as a result of medication intake. This process will allow us to better understand the mechanisms underlying the therapeutic effects of strengthening exercise for persons with Parkinson disease.
The proposed studies will assess 1) the mechanisms for the age-related increase in fatigability during dynamic exercise (Aims 1 and 2) and 2) the effectiveness of high-velocity resistance training coupled with blood flow restriction (BFR) in improving muscle power output and fatigability in older adults (Aim 3). The first two aims are cross-sectional studies comparing young (18-35 years old) and older adults (≥60 yrs old) to test our central hypothesis that the greater accumulation of metabolites and increase in fatigability in older adults is due to either age-related impairments in skeletal muscle bioenergetics (Aim 1) and/or vascular dysfunction (Aim 2). These two aims will integrate techniques to assess whole-muscle bioenergetics (31P-MRS) and in vivo vascular function (near infrared spectroscopy; NIRS and doppler ultrasonography) with in vitro assessment of single fiber bioenergetics (epifluorescence microscopy) and vasoreactivity of isolated skeletal muscle arterioles (video microscopy). We will then determine whether bioenergetics, vascular function and fatigability are altered in older men and women in response to 8 weeks of resistance exercise training of the lower limb both with and without blood flow restriction (Aim 3).
This study will address a gap in the literature and advance the field of minority men's health. Specifically, it will be the first randomized controlled trial of resistance exercise as a dual intervention for depression symptoms and CVD risk reduction with depressed Black men.

Our overall goal is to develop therapeutic interventions to improve upper-limb motor function in hemiparetic persons based on an improved understanding of the mechanisms responsible for its loss and recovery. We intend to rigorously evaluate the efficacy of these interventions with clinical trials, and to study the mechanisms by which these interventions affect motor recovery. In this proposal, we will use a controlled, randomized, double blind clinical trial to study the effects of shoulder and elbow strength training in subjects in the subacute phase of recovery following stroke.
To understand the effects of leg strengthening exercise, we will study the effects of strength training of the legs in four groups of people: (1) osteoarthritis (OA) with knee pain; (2) OA without knee pain; (3) no OA but elderly with knee pain; and (4) normal elderly with no OA or knee pain. In each of the first three groups, we will look at whether people who do strength training have less pain and/or slower progression of x-ray signs of OA over 30 months than people who perform nonstrengthening, range-of-motion exercises. We are including the fourth group to find out whether people with OA (groups 1 \& 2) have the same response to strength training as healthy elderly people, and whether those with knee pain (groups 1 \& 3) have the same response to training as those without joint pain.
This is a prospective, randomized controlled trial that will enroll patients undergoing unilateral meniscal root repair or meniscus transplant. The objective of this study is to determine if immediate postoperative strength training of the contralateral (non-surgical) lower extremity reduces postoperative loss of strength in an immobilized lower extremity. After the completion of surgery, patients will be randomized to either the experimental treatment (Group 1) or control group (Group II)for postoperative rehabilitation.
The investigators propose to compare the effects of a 12-week, supervised, site-based group yoga intervention on cognitive function, functional fitness, and well-being in middle-aged cancer survivors. Subjects will be randomly assigned to one of three exercise conditions: a yoga group, an aerobic walking group or a strength training group. All sessions (2-3 times per week) will be led by a trained exercise leader for a total of 150 minutes of exercise each week for the 12-week intervention.
The purpose of the study is to determine how two different blood flow restriction training programs used in conjunction with standard rehabilitation affect leg strength. By doing this study, the investigator hopes to learn if one program improves strength and function more than the other. The investigator also hope to learn how the training affects the properties of muscle in participants who will or have had anterior cruciate ligament (ACL) reconstruction. These results will help define how the training programs are working. There will be no charge to the participant for their physical therapy visits as long as they are part of the study The initial visit and follow up assessment at the end of the training will each take up to 6 hours (2 hours for MRI, 2 muscle biopsy, 2 for muscle strength, movement mechanics and questionaires). The physical therapy visits will range from 60-120 minutes depending on the participant's stage of recovery and the activities to engage in. Training sessions will be held 3 days a week for approximately 4 weeks before surgery and up to 24 weeks after surgery. There will be a total of 4 additional study visits over a 7 month period. The first visit will be used to capture baseline conditions of their knee and thigh muscles (muscle biopsy, MRI, strength). The second visit will occur right before surgery to assess changes during prehabilitation (strength and walking mechanics). The third visit will occur 4-5 months after surgery and will be a complete reevaluation of their thigh muscle and knee function (muscle biopsy, MRI, strength, gait). The last visit will occur 6-7 months after surgery and will involve an assessment of their thigh muscle strength, walking, and jumping form. The muscle biopsy and magnetic resonance imaging portion of the study will occur in the outpatient unit of the Center for Clinical and Translational Science at the UK Medical Center and the MRI center located on the medical center campus. The muscle biopsy will take an additional 15 minutes and the MRI up to two hours (1 hour per leg). It can take up to 4 hours total to complete both procedures. The investigator will accommodate participant preference for scheduling.

The purpose of this study is to determine the effects of food supplements and strength training on appetite, the amount of energy used, and body composition.
High-resistance, short-duration inspiratory muscle strength training (IMST) is a novel lifestyle intervention involving 30 inhalations against a resistive load which requires only \~5 min/day and is thus ideal for youth with T2D (Y-T2D). We seek to 1: assess changes in casual and 24-hr SBP, endothelial function, and arterial stiffness after 3 months of IMST vs. sham training in Y-T2D, 2: Define changes in eGFR andalbuminuria after 3 months of IMST vs. sham in Y-T2D, 3: Interrogate mechanisms of IMST by translational assessments of NO bioavailability, endothelial NO synthase (eNOS) activation, and ROS/oxidative stress, and determine the role of circulating factors.
This is a 12-week randomized, controlled trial that seeks to examine the effect of Vivo on 1) change in lower extremity strength defined as number of chair stands done in 30 seconds and 2) change in average glycemic level (HbA1c) compared to a wait list control.
The investigators hypothesize that new runners participating in an 8 week strength and coordination training program prior to beginning to run will 1) display different coordination patterns , and 2) experience fewer injuries, compared to new runners who do not perform strength or coordination training prior to running.
This pilot study will test the feasibility and acceptability of a 12 week combined aerobic and strength training intervention among persons with HIV who are age 50 or older and do not exercise frequently, and its preliminary effects on aging-related outcomes . The study uses an randomized, controlled trial design and is intended to lead to a larger clinical trial with long-term follow-up. The intervention incorporates small group instruction from a trainer, a small wearable accelerometer to provide accurate data on physical activity, and real-time feedback to participants about exercise levels. The primary outcome measure will be changes in fitness, measured as change in maximal oxygen consumption (VO2 max). The control group will receive a comparable exercise intervention after they complete 12 weeks of observation.
A growing body of knowledge has documented that the diaphragm, the primary muscle of breathing, atrophies and weakens within days of instituting mechanical ventilation support. Diaphragm weakness has been implicated as a major contributor to difficulty with weaning, or breathing without ventilator support. This study will test whether instituting a diaphragm strength training rehabilitation program will reduce the time patients require mechanical ventilation in a surgical intensive care setting.

This research on Functional Incidental Training ( FIT) primarily involves women residing in community nursing homes. It is an individualized rehabilitative protocol intended to improve mobility, endurance, strength and continence in frail, older, functionally impaired and disabled veterans. Objectives of the project are as follows: 1) Test the effects of FIT on transfer ability, continence, ambulation/mobility, balance and fall risk, strength, and endurance; 2) Determine the characteristics of NHCU residents who respond to FIT; 3)Identify the most sensitive outcome measures related to FIT; and 4) Determine the labor costs of FIT relative to usual care.
Loss of muscle mass and strength is a well-established outcome of normal aging. Muscle strength and mobility are also dependent on the quality and strength of connective tissue, which surrounds skeletal muscle. These layers, which are continuous with tendons, allow for the effective transfer of tension from skeletal muscle to bone to enable movement. Importantly, skeletal muscle strength is directly related to connective tissue strength. Greater tendon connective tissue cross-sectional area and stiffness optimize force transfer through tendon to maximize musculoskeletal function. As with skeletal muscle, tendon connective tissue quality declines with age. Previous research indicates that resistance training can improve muscle strength in older adults, but may not counter the effects of aging on tendon. The specific problem is that no approaches are available that benefit both skeletal muscle and tendon health to minimize loss of muscle mass and quality while also improving connective tissue quality and function in older adults. A critical need exists to assess approaches that improve both muscle and connective tissue strength and function. This need is highly relevant for older women, due to their higher risk of sarcopenia than men. Resistance training, especially when combined with higher protein intake, has been consistently shown to improve muscle mass and strength in older adults. Further, emerging research indicates that diets rich in total and indispensable amino acids (as in beef) augment exercise-induced improvements in tendon cross-sectional area in rodents and young humans. However, limited research exists on the impact of beef consumption combined with resistance training on muscle and tendon tissue outcomes, especially in older women. This research study will assess the effects of consuming a healthy, protein-rich diet emphasizing lean beef, compared to a healthy, normal-protein, lower beef diet (control 1), and a healthy protein-rich, lower beef diet emphasizing non-beef/red meat protein (control 2) on resistance training-induced changes in muscle and tendon tissue size, strength, and quality in older women.
This study will examine the effects of Oceanix™, an antioxidant supplement, on muscle performance, immune and endocrine function, recovery and safety in participants undergoing resistance training. Measures of muscle performance will include isometric testing in the bench-press and mid-thigh pull and ground reaction forces in the counter movement- and squat-jump. Markers of immune function will include salivary immunoglobulin A (IgA) as well as serum total antioxidant capacity (TAC) and superoxide dismutase (SOD) while endocrine function will be measured by salivary cortisol and testosterone. Recovery will be measure by plasma creatine kinase (CK) and perceptual measures will be assessed using a validated perceived recovery status (PRS) scale. Safety metrics will be indicated by a comprehensive metabolic panel (CMP), complete blood count (CBC), and urinalysis (UA). Additionally, the modified Borg Rating of Perceived Exertion (RPE) will be administered following each training session to grade physical exertion and monitor progression of the training protocol.
The investigators will compare differences in quadriceps strength, leg girth, and functional outcome scores between two groups of patients after weeks 6 and 12 as well as 6 months following meniscus or articular cartilage repair/restoration requiring 6 weeks of non-weight bearing or limited weight bearing status in a brace at 0° degrees of knee extension. One group will receive BFR with standard post-operative rehabilitation for 12 weeks followed by the standard protocol progression for the remainder of the treatment program. The other group will receive standard post-operative rehabilitation without BFR for the duration of treatment program.
