Filter by:The purpose of the present study is to evaluate the long-term effects of 1 year of high-intensity fitness training and low-intensity whole-body vibration training on muscle strength and functionality. Therefore, muscle strength and functionality are measured after a 6-yr interval in older adults (65+).
This study wants to understand which direction of shoulder movement and what posture of shoulder are best for the procedure of muscle strength testing of the muscle pectoralis major(PM). We will use muscle activity signals (sEMG) and force measurement to analyze the contribution of two parts of PM in three different contraction direction with three different shoulder postures.
This is an exploratory study based on the hypothesis that kidney transplant patients treated with an immunosuppressive therapy based on an inhibitor of the mammalian target of rapamycin (m-TOR) may increase resistance to physical exercise, which would result in an improvement in the quality of life of these patients.
The aim of this study is to investigate the efficacy of the Adductor-Canal-Blockade versus the femoral nerve block versus placebo on muscle strength in healthy volunteers. The investigators hypothesize that the Adductor-Canal-Blockade results in a lesser reduction of the quadriceps muscle strength compared to the femoral nerve block.
The purpose of this study is to evaluate the effects of experimental knee pain on the muscle strength gain after 8 weeks of strengthening exercises for the quadriceps. It is hypothesized that experimental knee pain will reduce the muscle strength gain following strengthening exercises in healthy volunteers.
The aim is to investigate the importance of vitamin D levels to achieve the effect of strength training. If we can show that vitamin D has an effect of training, the ultimate goal is to find out why and how vitamin D affects muscle. This would potentially have important implications for public health. Since a large number of populations, including elderly, are shown to have too little vitamin D and also has low muscle strength, it will be essential that these people added vitamin D in relation to training and rehabilitation.
Introduction: Vibration has been used to enhance muscle strength development during resistance training. Aim: To assess the effect of adding vibration to a regular resistance training program, using free weights, on muscle strength and everyday functioning of upper limbs in untrained adults Methods: 60 healthy untrained adults, 30-65 yrs, will divide into two groups: experiment and control. Training program will include 24 sessions, over a course of 8 weeks. The experiment group will use a 1 kg vibrating weights and the control group will use a standard 1 kg free weights. Every session will include 10-15 min of 3-5 standard resistant exercises for upper limbs. Each subject will perform an Isokinetic evaluation of muscular performance, for upper limbs, in 3 occasions: before starting the program, immediately after completing the 8-weeks training program and 4 weeks afterwards, to check the chronic effect of each training regime. Each subject will complete a DASH (Disabilities of the arm, shoulder and hand) questionnaire at 4 occasions- as mentioned above and one more time, when completing the first 4 weeks of the training program, to reject any development of negative effects of the training program, such as pain or inflammation of the joints .
The purpose of this study is to determine whether neuromuscular electrical stimulation, strengthening exercises, or combination of both over lower limbs are effective in the improvement of the stability fundamentally against falls, greater independence and, therefore, better quality of life in elderly over 75 years.
The stretching is performed within sports to improve muscle performance and prevent muscle injury. However, recent studies are contradictory with common practice. Then raised the possibility that stretching before physical activity performed can decrease the muscle performance of healthy subjects.
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.
