Strength Training Effects

The goal of this interventional study is to assess the training effects in a training schedule in which eccentric overload training and eccentric cycle training are used. Researchers will compare a training program of eccentric overload training and eccentric cycling training with a traditional training program of strength and cardio training in people with heart failure with reduced ejection fraction. This study will be delivered in a cardiac rehabilitation setting.

The goal of this clinical trial is to determine how male and female former athletes experience pain and respond to moderate-intensity exercise (strength versus aerobic) compared with both current master's athletes and nonathletes. The main questions this study aims to address are: 1. How do former athletes, master's athletes, and nonathletes experience pain? 2. How do different types of moderate-intensity exercise (strength versus aerobic exercise) influence pain in former athletes, master's athletes, and nonathletes? Participants will complete 3 different testing sessions: 1. Baseline testing including assessments of strength, cardiorespiratory fitness, and pain; 2. Strength exercise: pain assessments will occur before and after moderate-intensity strength training exercise; 3. Aerobic exercise: pain assessments will occur before and after moderate-intensity aerobic exercise. There will be a washout period of approximately one week or greater between each of the three different testing sessions. The order of conditions (strength versus aerobic exercise) will be randomized (crossover randomized trial design).

This study investigates whether taking the amino acid L-serine, either alone or in combination with targeted strength training, can have a positive effect on mental performance, brain function, and physical fitness in older people. Healthy, independent women and men aged 65 to 85 are eligible to participate. Participants will be randomly assigned to one of three groups: placebo, L-serine, or L-serine combined with strength training. Cognitive tests, physical performance tests, and blood and brain tests will be conducted over a period of 48 weeks. The aim is to gain a better understanding of how nutrition and exercise can contribute to healthy aging.

Approximately one third of the population over the age of 65 falls at least once a year. The risk of falling is in increased in older patients with tumor diseases. In addition to high treatment and care costs for the healthcare system, falls often lead to a decrease of quality of life, a reduction in physical performance and a loss of independence. Despite the high risk, falls in cancer patients have not yet been scientifically investigated in detail. For patients with multiple myeloma in particular, very little data is available on the prevalence, risk factors and effects of falls. In this study, a fall risk assessment is carried out in patients with multiple myeloma. Furthermore, a patient-specific training intervention for fall prevention will be implemented. The aim of the study is to identify possible fall risk factors in multiple myeloma patients and to establish a structured exercise intervention that minimizes the risk of falls and injuries.

The goal of this clinical trial is to study and evaluate whether a protocol of creatine supplementation, with or without multicomponent training, improves functional and cognitive capacity in individuals over 75 years old. The results of this study will further our understanding of creatine supplementation effects in the context of older patients and in combination with multicomponent training, thereby enhancing patient care strategies. Additionally, the goal is to improve the quality of life for the elderly and the efficiency of the healthcare system. The main questions it aims to answer are: 1. Does creatine supplementation alone provide physical, functional and cognitive benefits to people over 75 years of age? 2. Is creatine supplementation safe for people over 75 years old? Researchers will compare creatine monohydrate supplementation with or without multicomponent training intervention to placebo supplementation with or without multicomponent training intervention to see if the creatine supplementation protocol leads to significant improvements in functional and cognitive outcomes. This comparison will help determine the effectiveness of the supplementation intervention in enhancing the overall well-being of elderly patients. Participants will: * Engage in a structured multicomponent exercise program designed specifically for elderly patients. This program will include activities focused on strength training, balance exercises, and walking to improve mobility and reduce the risk of falls. * Attend supervised exercise sessions several times a week, allowing for individualized attention and adjustments based on each participants abilities and health status. * Be monitored for changes in functional capacity using standardized assessments, which will measure improvements in mobility, strength, and overall physical functioning. * Undergo cognitive assessments to evaluate any changes in cognitive status throughout the intervention and during follow-up periods after discharge. * Participate in surveys and interviews to assess their quality of life, including physical, emotional, and social well-being, before and after the intervention. * Attend follow-up assessments at designated intervals to track their progress and outcomes, ensuring that any long-term benefits of the exercise program are recognized and documented. Inclusion criteria will focus on individuals aged over 75 years. Participants must be capable of communication and ambulation, either independently or with assistance. * Life expectancy ≥ 6 months. * Barthel Index \> 60. Exclusion criteria will ensure the safety and appropriateness of the intervention. Individuals who explicitly refuse to participate or cannot provide informed consent will be excluded. Additionally, those with a life expectancy of less than three months, terminal illnesses, or significant medical contraindications for exercise will not be eligible. Participants with moderate to severe neurocognitive disorders or disabilities that severely limit mobility will also be excluded to maintain the integrity of the intervention. This clinical trial aims to recruit a total of 120 participants from the Geriatric Department or Primary Care, providing a comprehensive dataset to analyze the effectiveness and safety of the multicomponent exercise program. By examining the outcomes related to functional capacity, cognitive status, and quality of life, the study seeks to provide valuable insights into the benefits of physical activity for elderly patients during hospitalization.
