640 Clinical Trials for Various Conditions
The goal of this clinical trial is to understand if people recovering from anterior cruciate ligament reconstruction (ACLR) surgery will complete mental imagery training and if this will improve their injured leg's strength. The main questions are: * Will people complete a five-day mental imagery exercise schedule while in physical therapy for ACLR? * Does mental imagery exercise help raise leg strength during ACLR recovery? Researchers will also compare if different mental imagery exercises involving leg extension or squats will change leg strength. Participants will be asked to: * Participate in two testing sessions to make measurements of leg function * Complete about 10 minutes of mental imagery exercises once per day for five days at home and write down whether they complete the exercises.
The aim of this study is to examine the development of a conceptual framework and provide evidence for reliability of a comprehensive hand therapy evaluation score. This approach provides a new standardized tool for upper extremity (UE) evaluation. Components of Pain, Range of Motion (ROM), Edema, Sensibility, Strength (PRESS), and self-reported Function were combined to create a baseline. Each assessment tool used for the PRESS to Function Approach assists in determining appropriate interventions.
Impaired neck muscle strength is related to neck pain, abnormal posture, and various cervical pathologies. Clinicians, therefore require objective, reliable and valid methods for quantifying neck strength. In a previous study, the investigators developed a novel, valid, and reliable method for measuring neck retraction strength, using a handheld dynamometer (HHD), in normal, healthy individuals. The investigators are now expanding this research to study a patient population. Specifically, to describe isometric neck retraction strength in patients with neck pain and to study the effects of physical therapy (PT) on that strength. Our hypothesis is that isometric cervical retraction strength will increase over the course of treatment and that there will be an inverse relationship between strength and the Numeric Pain Rating Scale (NPRS) and Neck Disability Index (NDI).
It is possible that the lower protein intake in vegetarians and vegans may relate to a decrease in grip strength. Furthermore, there is limited research examining the effects of plant-based protein intake on strength and LBM independent of an exercise training component. The present study was designed to examine relationships between strength, protein intake, and LBM in underactive vegetarian and vegan adults, as well as the impact of protein supplementation (18 g mung bean protein daily) on these indices.
Humans lose muscle and strength as they get older. Further, ageing is accompanied by loss in cognitive function. It is not quite clear why this happens; however, it is known that the loss of muscle and strength can increase risk for physical and mental health risks and impair the ability of older people to remain physically independent. Weight lifting and proper nutrition, particularly eating high quality protein at the proper time and quantity, may help prevent these losses when a person gets older. To determine if regular beef consumption as part of a higher protein diet aids the muscle adaptive response to resistance training and improvements in cognition, seventy healthy individuals will be recruited to lift weights 3 times a week for 10 weeks. One group (n=36) will consume the Recommended Dietary Allowance (RDA) for protein (0.8g/kg/day), while the other group (n=36) will consume an amount twice the RDA (1.6g/kg/day), which is in agreement with recommendations from the American College of Sports Medicine. Participants will have their muscle strength tested and samples of blood and muscles will be collected before and after training to determine how the muscle adaptive response to resistance exercise is affected by higher protein intake. In addition, participants will undergo cognitive assessments at baseline and follow-up to determine the influence of improving muscle strength on attention and memory. Overall, the investigators proposed study will use sensitive methodology to determine if providing protein above the RDA and at optimal times during the day in combination with a weight lifting program can help make someone stronger and build larger muscles than someone consuming the RDA, as well as what processes may be responsible for helping the muscles to get bigger and stronger.
The purpose of this study is to determine whether a commonly prescribed drug, metformin, can enhance the benefits seen during resistance exercise such as increased muscle mass and strength.
This study investigates the strength gains associated with resistance training in a group of 18 male high school athletes consuming either a whey protein supplement or chocolate milk following their exercise.
It has been suggested that high amounts of total serum testosterone levels correlate with higher lean body mass, lowered fat mass, greater muscle strength, and faster recovery. These suggestions drive athletes and body builders to find ways to raise their testosterone levels. Many athletes and bodybuilders look to alternative methods to anabolic steroids in order increase their testosterone levels without legal repercussions or physiological side effects. Herbs and other plant extracts have been introduced as a possible source to naturally boost testosterone levels. Research supporting the use of herbs and plant extracts has been shown to be equivocal. However, evidence in studies with hypogonadal men suggests that longjack root may naturally boost testosterone levels. Onnit Labs, LLC has packaged this supplement (T+) which claims it can naturally boost testosterone and lower estrogen levels and subsequently improve performance. This product is a powder (11g) that is mixed with 16 oz of water and consumed 20 minutes prior to anaerobic workouts, such as high intensity weight training. T+ is a multi-ingredient supplement that consists of vitamins B5 and B6, magnesium aspartic acid, mucuna pruriens, longjack root, nettle root, red clover luteolin, resveratrol, beta- alanine, branch chain amino acids, L- glutamine, Bioperine, and Fibersol 2. The active ingredients purported to boost plasma testosterone levels are mucuna pruriens, longjack root, and magnesium aspartic acid. The active ingredients claimed to lower plasma estrogen concentrations are red clover, luteolin, resveratrol and nettle root. All other ingredients (Branch Chain Amino Acids and Beta-Alanine) have been documented to improve exercise performance. It is hypothesized that there will not be any physiological changes after supplementation of T+. It is also hypothesized that performance will not be affected by the supplementation of T+.
This study evaluated the efficacy, safety and tolerability of multiple doses of bimagrumab/BYM338 vs placebo, when administered intravenously (i.v.), on physical function, muscle strength, and mobility in patients with sporadic inclusion body myositis (sIBM).
This study will investigate the effects of a soy/dairy protein blend on muscle growth and strength. In sports nutrition and in aging it is important to have healthy muscles. This can be achieved with exercise and nutrition. Consumption of protein following resistance exercise can promote healthy muscle growth and help improve strength. Young healthy men will be studied during a 12 week resistance exercise training program and be given protein supplements every day during the study. The hypothesis is that a blend of soy, whey and casein will induce a greater muscle gain and strength increase than the control.
The purpose of this study is to evaluate the effects on strength, balance, and neuropathic symptoms (numbness, tingling, pain, weakness) of a 12 week, bi-weekly, 60 minute, group exercise program designed to improve lower extremity strength and balance with persons with oxaliplatin induced peripheral neuropathy.
This study will evaluate the effects of low-intensity strengthening exercise on the brain (thinking and processing speed) for patients with early dementia, compared with normative older adults. Participants will engage in 3 months of exercise 3-5 times per week using a chair and small weights. It is hypothesized that there will be a significant improvement in brain function.
This pilot study is designed to analyze the effects of Vibration Therapy (VT) on grip strength and level of forearm contraction by measuring hand grip dynamometry and surface Electromyography (sEMG) using the BioPac sEMG and digital dynamometry devices after the application of both passive and active Vibrational Therapy (VT) using the PowerPlate.
The goal of this observational study is to learn if simple tests for frailty and muscle strength can help predict which older adults (age 65 and older) are at higher risk for problems after major abdominal surgery. The main questions it aims to answer are: * Do measures of frailty and muscle strength, taken before surgery, predict complications after surgery? * Can these tests be easily done during a routine pre-surgical visit? Participants will: * Complete brief tests measuring muscle strength, breathing strength, physical function, nutrition status, body composition, and memory during a regular pre-surgical clinic appointment. * Allow researchers to review their medical records 30 and 90 days after surgery to identify any complications or health problems.
The study tested whether giving young, partnered military service members access to an online relationship help website would help prevent future relationship problems compared to partnered service member who did not have access to the website
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.
The goal of this study is to find out if a tool called an external cueing device (ECD) can help young swimmers improve their shoulder function. An ECD is a tool that limits arm movement and gives the swimmer a target to focus on while doing exercises. The main questions this study will answer are: * Does using an ECD during certain exercises improve muscle strength? * Does using an ECD while exercising help with shoulder stability? Participants will: * Test their shoulder muscle strength and stability at the beginning of the study. * Complete 8 exercises as part of their regular dry-land training program for 6 weeks. * Repeat the same tests after 3 weeks and again at the end of the study.
This study investigates the benefits of two different types of 2 minute activity breaks during sedentary workdays for people who sit for long periods of time in sedentary jobs.
Recovery of arm and hand motor control is critical for independence and quality of life following incomplete spinal cord injury (iSCI). Blood flow-restricted resistance exercise (BFRE) has emerged as a potential treatment addressing this need, but treatment guidelines and research reporting effectiveness are sparse. The purpose of this work is to provide case reports of people with cervical iSCI who use BFRE supplemented by electrical stimulation (ES) to increase the strength and functional use of selected upper extremity muscles.
This study will examine the effects of a single session of a quick stretch technique delivered to the neck on neck and shoulder motion as well as shoulder strength in collegiate overhead athletes.
The purpose of this clinical trial is to look at tyrosol's effects on endurance, strength, and fatigue resistance in humans. Additionally, the combination of tyrosol and creatine monohydrate will also be looked at to determine if there is a cooperative effect from using both together. It will be conducted over a 4-week period to compare the effects of the following substances: 1) tyrosol, 2) a placebo (a look-alike substance that contains no drug), 3) creatine, and 4) a combination containing both creatine and tyrosol. Endurance, strength, and fatigue resistance will be compared between groups through repeated testing (described below). Participants who pass initial screening will be invited on-site for day one (Visit 1) of testing where they will proceed with a series of tests which will include the following: (1) body composition; (2) cognitive testing; (3) full-body strength testing; (4) grip strength on both hands; (5) muscle power testing; (6 \& 7) Resting blood lactic acid testing followed by 5RM (repetition maximum) bench press, leading to multiple sets of bench press (based on the previous weight) completed to failure, followed by another blood lactic acid reading; (8) a repeat of the muscle power testing; (9) a 1 mile time trial run completed as fast as possible. After the 4-week supplementation period (\~28-34 days), all original measures will be repeated as before in the same order (Visit 2). Approximately 24 hours later (Visit 3) participants will then repeat all physical testing procedures except tests 1, 6, 7, and 8, to determine physical recovery. Additionally, questionnaires for soreness and perceived recovery will also be completed at the beginning of Visit 2 and 3, and again on its own as the only testing event at 48 hours post-Visit 2 (visit 4).
The purpose of this study is to examine the feasibility, acceptability, preliminary efficacy, and candidate gut-brain mechanisms of an optimized positive psychology (PP) intervention for patients with irritable bowel syndrome (IBS), entitled "WISH," compared to an educational control intervention.

Participants receive either 2.4g/day of PeptiStrong® supplement capsules or placebo capsules for 14 days until a strenuous exercise session. For the last 3 days, 2/3 of them stay on the same treatment and 1/3 of them switch from placebo to PeptiStrong®.
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.
The objective of the current study is to determine whether lifting lighter loads close to failure improves strength training adaptations and function in older adults. The main questions it aims to answer are: 1. The effect of light loads on physical function 2. The effect of light loads on muscle mass, power, and strength Researchers will compare a light-load, high-repetition program to a standard strength training program. Participants will perform supervised strength training twice per week for 20 weeks.
Low back pain is one of the most common chief complaints amongst adult patients in the ambulatory clinic and emergency settings and poor core strength is a known underlying cause/perpetuator. Additionally, it is one of the most common reasons active-duty military personnel seek medical care (absolute 2015; absolute 2016; absolute 2017). Moreover, musculoskeletal conditions represent a common reason service members are placed on limited duty and considered medically not fit to deploy. The AllCore360° has the potential to prevent pain and injury, decrease pain as well as reduce duty, fitness and mobility restrictions in active-duty members with low back pain.
Teachers are at notable risk for depression and anxiety. The present study tests an app-based mindfulness intervention for teachers in their final year of training with the goal of preventing the deterioration of their mental health during the transition into the classroom. The project will strengthen the research environment at the University of Alabama and will involve undergraduate research assistants in each step of the research process.
The purpose of this research is to understand how training the muscles used for breathing (inhalation) affects menopausal hot flashes, sympathetic nerve activity and sleep.
Open-label, non-randomized, prospective, multi-center, self-controlled clinical study.
Segmental facilitation, originally proposed by Korr in the 1950s, suggests that certain spinal segments can become hyperexcitable, leading to chronic pain development. In a facilitated segment, neurons governing sensory, motor, and autonomic functions are in a state of heightened sensitivity, making them responsive to normally weak stimuli. Clinical signs include non-fatigable muscle weakness, brisk reflexes, muscle hypertonicity, tenderness upon palpation, and trophic changes like an orange-peel appearance in the affected segment's innervated areas. It's hypothesized that increased synaptic excitability in facilitated segments could cause vasoconstriction and reduced blood flow, contributing to trophic changes and muscle hypertonicity. Manual therapies like dry needling have been shown to alleviate muscle inhibition in the extremities. Previous studies have demonstrated that mobilization of the C5-6 joint can reduce non-fatigable weakness in shoulder external rotators primarily innervated by these segments. However, the neurophysiological effects of dry needling (DN) on muscle inhibition due to a facilitated segment remain unclear. While DN has been observed to increase local tissue blood flow, its potential to mitigate the clinical signs of segmental facilitation is uncertain. While DN has been observed to increase local tissue blood flow, its potential to mitigate the clinical signs of segmental facilitation is uncertain. Therefore, this project aims to investigate whether DN applied at a facilitated segment could normalize blood flow to its associated muscles. Specifically, this study will explore whether DN at the C5-6 level improves blood flow in the infraspinatus muscle, enhances shoulder range of motion, and influences muscle strength over time. The secondary purpose is to determine whether C5-6 DN will reduce the number of tender points in the muscles supplied by C5-6.
