Filter by:The purpose of this study is to explore the feasibility and acceptability of a new physical activity technology (Jintronix) based on TV screen, virtual games and motion sensing cameras among pre-disabled older adults.
The purpose of this pilot study is to determine whether adipose tissue loses some of its ability to expand in response to overfeeding in older compared to younger men. The investigators hypothesize that the adipose tissue response to overfeeding may be weakened in older when compared to younger men, thereby leading to worsened ectopic storage depots for older men.
The aim of this study is to empirically evaluate the impact of a Dance/Movement Therapy program adapted to older adults. Participants over 60 years old are enrolled in one of three groups: Dance/Movement Therapy, Aerobic Exercise or Waiting List (control group) for 12 weeks. The training groups occur 3 times a week for 1 hour each session. Physical condition, cognitive function, general health and lifestyle, and stress hormones are assessed at baseline, after 12 weeks and after 28 weeks.
The purpose of the proposed study is to determine the effects of consuming a high protein diet on fecal microbial communities, gastrointestinal function and symptoms, and general wellness in older adults.
Resistance training has shown the most promise among interventions aimed to combat aging muscle atrophy as it enhances strength, power, and mobility function, but induces varying degrees of skeletal muscle hypertrophy as the investigators demonstrated in the initial 5-year funding period of this award (2001-2006). In the subsequent 5-year funding period (2007-2012), the investigators built on this prior work by using a dose-response approach in older adults - ultimately to optimize the treatment of age-related muscle atrophy. The investigators tested four, long-term resistance training prescriptions in older (60-75 yr) women and men to determine which prescription maximizes mechanisms driving muscle regrowth. One of the innovations in this project was the use of a 4-wk pre-training program to reach a plateau in the early, non-muscle mass adaptations, thereby establishing a true baseline from which both mechanisms of measurable muscle hypertrophy and functional consequences of hypertrophy could be studied in a tightly integrated fashion without bias in the subsequent experimental period. A randomized design was used to test the overarching hypothesis that a novel program of mixed strength and power training would optimize the anabolic environment to promote muscle hypertrophy and robust gains in performance. This hypothesis was tested with three specific aims.
PURPOSE: The purpose of this study is to investigate whether High Intensity Interval Training (HIIT)can improve the health and wellbeing of pre-diabetic elderly adults. In particular, there is specific interest in describing the effects of an interval exercise program on inflammatory state and immune function. DESIGN: Subjects will be sedentary, 65 to 80 years old adults, with prediabetes as defined by fasting plasma glucose (100 to 125 mg/dl). Before and after a 10-12 week High Intensity Interval Exercise training program subjects will undergo several tests including: 1) a maximal treadmill test, 2) an Oral Glucose Tolerance Test, 3) muscle biopsy, 4) body composition, 5) several physical function tests and 6) other health related measures including lung function, arterial stiffness and several blood measures (e.g. liver enzymes, kidney function). DATA ANALYSES & SAFETY ISSUES: As there are no comparison groups, data analyses will consist of performing paired t-tests on pre and post exercise training values for each of the measurement variables of interest. In addition, the data will be used to provide power calculations for future grant proposals. High Intensity Interval Training is a very safe exercise modality. The regular use of vigorous intensity exercise intervals have been used extensively in exercise training. In fact, the exercise intervals will start at levels lower and will be of shorter duration than were used during the maximal exercise test. They will then be carefully and slowly made to be more challenging as each subject is able to safely tolerate. HYPOTHESIS: The investigators hypothesize that HIIT will result in significant improvements in markers of inflammation, immune system markers and other health-related risk factors.
This study is to determine the efficacy and safety of JUVÉDERM VOLUMA™ XC when used in the facial temporal regions based on the change in the score of the investigator's Temporal. This study will be an open label, single center study.
The objective of this study is to determine whether augmentation of prefrontal brain excitability using noninvasive transcranial direct current stimulation (tDCS) lessens the severity of the symptom triad associated with cerebral microvascular disease (CMD); that is, slow gait, cognitive dysfunction and depressive symptoms. Investigators will complete this objective by conducting a pilot, double-blinded randomized controlled trial of a 10-day intervention of real versus sham tDCS in 40 subjects.
Metformin, an FDA approved first-line drug for the treatment of type 2 diabetes, has known beneficial effects on glucose metabolism. Evidence from animal models and in vitro studies suggest that in addition to its effects on glucose metabolism, metformin may influence metabolic and cellular processes associated with the development of age-related conditions, such as inflammation, oxidative damage, diminished autophagy, cell senescence and apoptosis. As such, metformin is of particular interest in clinical translational research in aging since it may influence fundamental aging factors that underlie multiple age-related conditions. The investigators therefore propose a pilot study to examine the effect of metformin treatment on the biology of aging in humans. Namely, whether treatment with metformin will restore the gene expression profile of older adults with impaired glucose tolerance (IGT) to that of young healthy subjects.
This study aims to carry out a safety evaluation of human cord blood and frozen plasma as treatment for pre-frailty , to assess whether the treatment can prevent and improve the aging process, and to identify useful clinical markers of frailty. The study is a randomized, double-blinded and placebo-controlled pilot clinical Trial conducted at CHA clinical trial institute.
