3 Clinical Trials for Various Conditions
This study will deliver a 9 week high intensity interval training (HIIT) class using functional movements within a community based gym. The class will be twice a week. Outcomes are focused on cardiovascular endurance, balance, strength and muscle size and muscle quality changes. The outcomes will be assessed weekly.
Men and women lose muscle mass and strength with age. Loss of muscle mass and strength is accompanied by a loss of muscle function which can lead to diminished quality of life and more importantly can lead to serious fall requiring medical treatment. The investigators hypothesize that the combined supplements of Calcium-HMB and Vitamin D will lead to decreased falls and to improved quality of life (QOL) for older adults. The investigators further hypothesize that the addition of a modest exercise regimen to these supplements will enhance the synergistic effects of both Calcium-HMB and Vitamin D. Subjects will consume the dietary supplement 2 times per day for 12 months. Tests will consist of the following: a) strength of subjects' legs and elbow by Isokinetic Dynamometer; b) body composition; c) hand-grip strength by hand-grip dynamometer; d) functional mobility, balance and agility (Get-Up and Get-Up-and-Go tests); e) filling out questionnaires; and g) having blood drawn for biochemical measurements. Testing will be performed at the baseline (0 months) and at 3, 6, 9, and 12 months.
The purpose of the study is to * Test the effect of a dietary supplement beta-hydroxy-beta-methylbutyrate (HMB) with and without Vitamin D to prevent and reverse the losses of muscular strength and functionality in older adults. The second aim of the study is to determine if HMB and Vitamin D improves markers of bone turnover in adults aged 60 plus years. HMB is a dietary supplement that comes from the amino acid leucine. HMB is found in foods and is made in your body after you eat protein (meat). Subjects will be randomized to one of four dietary supplement groups and will participate in a 3-day per week exercise program for 12 weeks. Each exercise day will be about 60 minutes long consisting of strength training exercises utilizing Theraband® stretch cords and jumping. Subjects will consume the dietary supplement 2 times per day for 12 weeks. Tests will consist of the following: * Measuring the strength of subjects' legs by using a Isokinetic Dynamometer * Measuring body composition * Measuring hand-grip strength using a hand-grip dynamometer * Measuring functional mobility, balance and agility by the time it takes for you to rise from a chair, walk around a cone 8 feet in front of the chair and return to the chair (Up-\&-Go Test * Filling out questionnaires and having blood drawn for biochemical measurements. Testing will be performed at the beginning and at 4, 8 and 12 weeks.
