Filter by:It is well known that regular resistance training (RT) can have health benefits. However, considerable heterogeneity in RT responses has been observed. The mechanisms underlying an individual's ability to respond to RT are mainly unknown but involve a complex network of genomic and non-genomic factors. The investigators aim to examine heterogeneity in physiological responses to RT while closely monitoring other environmental factors (e.g., physical activity levels, nutrition, sleep, and stress). Participants are healthy sedentary men and women aged 18-45 (n=240). A controlled 12-week RT intervention will be conducted to characterize RT response. Data will be collected before, during, and after the study period by using measurements of body composition, muscle size, and physical fitness characteristics, as well as by collecting blood samples and questionnaires. The investigators will identify the underlying factors contributing to why people differ in their physiological responses to RT. For this, comprehensive background data will be collected to identify common denominators underlying individual differences in response to RT. The investigators will use sophisticated analytical methods to reveal new predictors of training response for different traits. This research project aims to gain insight into the sources of individual variation in physiological responses to RT. On this basis, exercise training can be personalized to optimize the benefits of RT for all individuals. Ultimately, the investigators will also be able to justify better using RT as part of individualized healthcare strategies in the future.
Sarcopenia characterised by loss of muscle mass, muscle strength and physical performance burdens many older adults since the condition is related to functional decline. Periods of inactivity such as during hospitalisation leads to further functional decline. It has been reported that the loss of muscle mass associated with sarcopenia not only entails a decrease in muscle mass but also changes in muscle architecture. Knowledge on changes in muscle architecture is essential since it is one of the most important determinants on muscle strength and thus physical performance. The main objective of this study is to investigate changes in muscle architecture and physical performance during acute hospitalisation and after discharge in older adults and subsequently the effectiveness of resistance training of the lower limb during acute hospitalisation. If successful, our study could have a great impact on the individual, as well as societal level, due to a better understanding of the factors related to sarcopenia and the prevention of functional decline as a result of hospitalisation.
Changes related to Cerebral Palsy (CP) include differences in muscle architecture and cortical activity. These result in weakness, decreased functional ability and limited participation in physical activity. Strength training programs, particularly those including power training components, show great potential in improving the gross motor function of youth with CP. However, this intervention is not currently offered in the Calgary area. Delivered via an innovative partnership with community stakeholders, this project will investigate the preliminary effectiveness of the program to enable youth with CP to achieve child and family centered goals. It will also investigate the feasibility of offering this type of program via a community-hospital partnership. Research Question & Objectives: 1. Can youth with cerebral palsy achieve their goals and improve their motor function through RIPT (Resistance Intensive Personal Training), a power training program offered jointly by specialized physiotherapists and fitness professionals in community settings? 2. What are the barriers and facilitators to delivery of RIPT in a community setting for youth, caregivers, clinicians, and program staff?
The goal of this clinical trial is to learn about the cause of dizziness and decline in walking ability in in older adults ≥65 years during chemotherapy treatment for colorectal cancer. Another goal is to investigate if a comprehensive geriatric assessment and three months' specialized physical group-based exercise three times/week can counteract muscle weakness, vertigo, instability, impaired walking balance, and neuropathy
This is a randomized controlled trial aimed to investigate the effects of different supplementary protein sources on muscle adaptations to resistance exercise. Young, healthy, recreationally active participants consuming an omnivorous diet with protein intake within recommended dietary allowance (RDA) (i.e.; 0.8-1.0 g.kg-1. d-1) will be recruited to undergo a 12-wk supervised resistance training program in combination with the intake of three 15-g daily doses (45g. d-1 total) of either a mixed plant- (i.e.; soy and pea protein) or animal-based (i.e.; whey protein) protein in drink form as a supplementary source of protein to their main meals of the day (i.e.; breakfast, lunch, and dinner). Before (PRE) and after (POST) the 12-wk intervention, participants will be assessed for body composition by dual-energy X-ray absorptiometry (DXA), muscle cross-sectional area (ultrasound) and fiber cross-sectional area (muscle biopsy), and maximal isotonic strength (1RM). Training consists of a resistance training (RT) program individually supervised by a researcher blinded to treatment in a laboratorial setting. Assessments will also be conducted in a blinded fashion.
Background: In postmenopausal women, an alteration in body composition occurs as a consequence of the secretion of low levels of serum estrogens by the ovaries. Observing an increase in abdominal and mammary fat mass and a decrease in skeletal muscle mass, which is also accompanied by loss of muscle strength and physical function, which leads early to a sarcopenia. On the other hand, the increase in estrogen production by adipose tissue has been associated with an increased risk of breast cancer during menopause because the mammary parenchyma is particularly sensitive to this type of estrogen. For this reason, Hormone Therapy (Aromatase Inhibitors and Tamoxifen) is prescribed in women with estrogen receptor-positive breast cancer. Antineoplastic treatments (Chemotherapy and Hormonal Therapy) have contributed to non-metastatic breast cancer currently presenting a high survival rate, not without adverse effects associated with the course of the disease, age and antineoplastic treatment, affecting various systems, but particularly skeletal muscle mass. Therefore, resistance exercise training has been proposed as an effective intervention strategy to increase muscle mass and strength in different populations. However, the level of muscle response to this type of training in postmenopausal women survivors of breast cancer with and without hormone treatment (Aromatase Inhibitors and Tamoxifen) is unknown.
There is an increasing number of elderly population, not only in Indonesia, but also in the world. With increasing of age, there is also an increasing number of elderly with sarcopenia and frailty. Both of the diseases can lead to dependency, decrease quality of life, and morbidity. Besides nutrition, physical activity, especially resistance training is proven to be beneficial in improving sarcopenia and frailty condition. Currently in Cipto Mangunkusumo National Hospital (RSCM), there is no comprehensive frailty prevention clinic in the geriatric inpatient clinics. This research can be the base of frailty and sarcopenia treatment in RSCM.
This study have like aim to examine whether insulin secretagogues have a potential ergogenic effect leading to a better exercise performance and post-exercise recovery in healthy individuals after a resistance training session. METHODS: This is a randomized, double-blind, placebo-controlled, clinical trial. The sample will consist of 44 men. Subjects will be randomly allocated (block randomization, www.randomizer.org) to the following groups: placebo (PFG, n=22) and sulphonylurea (GFS, n=22). The study will consist of 3 visits 7 days apart. On visit 1 the participants will ask to sign an informed consent form and will carry out medical evaluation with anthropometric assessment. At that visit they will perform a one-repetition maximum test of the upper limbs by using the horizontal bench press and of the lower limbs by using the 45º leg press. On visit 2, they will perform a second round of similar 1-RM tests to determine workloads for the study session [sulphonylurea (gliclazide) vs. placebo]. The experimental exercise session will be held on visits 3. Gliclazide modified release 60 mg (Diamicron® MR) or placebo (starch, sodium lauryl sulfate and Aerosil) will be orally administered as matched capsules (same color, flavor, smell and size) 8 hours before the beginning of exercise session, double-blind. In the experimental session, first, warm-up on the bench press and leg press, both with workload at 50% of 1-RM will be carried out. After a 2-minute rest, the resistance training session will be started. It will consist of 4 sets of bench press and leg press exercises at 65% of 1-RM with maximum repetitions until concentric failure. The bench press exercises will be followed by the leg press exercises with no interval between them. A 2-minute interval will allowed after each series of exercises. Measurements for heart rate (HR) and Visual Analogue Scale (VAS) for Pain will be taken before, between each series of exercises and 24 and 48 hours after session. Venous blood samples will be obtained before, immediately after, 24 and 48 hours after, for determining serum levels of creatine kinase isoenzyme MM and lactate dehydrogenase. Capillary blood for glucose determination will be collected from the digital pulp using a glucometer before and immediately after. Resistance training volume will be calculated for each type of exercise as well as total training volume for each session as a product of exercise workload and number of series and repetitions.
Nutritional interventions witch stimulate the rate of muscle protein synthesis are relevant for the development of therapeutic strategies aimed at attenuating the loss of mass and muscle strength related to aging (sarcopenia). To aim of the study is to investigate the effect of protein supplementation on body composition, muscle activity, muscle strength and plasma concentration of inflammatory biomarkers of elderly with type II diabetic, submitted to 12 weeks of resistance training. This is an interventional, controlled, randomized, double-blind study. The population of the present study will be composed of 40 men with type 2 diabetes aged between 70 and 74 years, whose body mass index (BMI) should be between 22 and 32 kg / m2. It will be composed of patients from the Diabetes Outpatient Clinic of the Endocrinology Department at the Medical School of the University of São Paulo. Elderly subjects will be randomized into two groups (n = 20) who will undergo resistance training for 12 weeks, twice a week, and receive protein or placebo supplementation. Exercises will be performed for the large muscle groups: pectoral press, paddling, leg-press, extensor chair, gastrocnemius plantar flexions and abdominal crunches. Protein supplementation will be performed immediately after strength training by ingestion of 20 g of whey protein diluted in water. Also, immediately after training the placebo group will receive 20 g of maltodextrin diluted in water. All participants will be instructed to ingest 1.0 to 1.2 g of protein / kg of body weight per day. 24-hour food recall and food frequency questionnaires will be performed throughout the study. The following evaluations (before and after 12 weeks training) will be applied: Anthropometric: body mass, height, BMI and hip waist ratio. Functional evaluation through isokinetic dynamometry of knee extensors and flexors and a maximal repetition (1RM). Evaluation of body composition through Bioimpedance balance. Evaluation of food intake will be obtained by means of a 24-hour recall and food frequency questionnaire. All the evaluations will performed after 6 months. The training sessions will have a frequency of twice a week for 12 weeks. Eight exercises will be performed for the main muscle groups. In each exercise, 3 sets will be performed between 8 and 12 repetitions. The intensity should be between 7 - 8 and will be monitored according to Subjective Effort Perception using a scale of 0 to 10.
The focus is performance nutrition. Resistance exercise can induce low level muscle damage in conjunction with impaired contractile function. Milk-derived proteins contain, or induce, bioactive properties that assist muscle recovery and restore/improve muscle function. The aim of the research is the recovery of muscle function following resistance exercise. In this study, the investigators propose to undertake a comparison of the ingestion of two milk-derived protein-based recovery drinks on muscle function after resistance exercise compares to an isonitrogenous, non-essential amino acid control.
