Clinical trials

The goal of this clinical trial is to learn whether elastic-band resistance training, with or without breathing training, can improve lung function and physical function in older adults with pulmonary function impairment living in the community. It will also learn about the safety and feasibility of these exercise programs. The main questions it aims to answer are: Does elastic-band resistance training improve lung function, lower-limb muscle strength, walking ability, and exercise tolerance? Does adding structured breathing training to elastic-band resistance training provide additional benefits for lung function and respiratory-related health status? Are these exercise programs safe and acceptable for older adults in a community setting? Researchers will compare three groups: elastic-band resistance training plus breathing training, elastic-band resistance training alone, and usual health education. This will help determine whether elastic-band resistance training is helpful and whether breathing training adds extra benefit. Participants will: Take part in a 12-week study Be assigned by chance to one of three groups Attend supervised exercise sessions 3 times per week if assigned to an exercise group Receive usual health education and daily activity guidance Complete lung function tests, muscle strength tests, physical function tests, and questionnaires at the start of the study, at 6 weeks, and at 12 weeks

This study is a double-blind, randomized, placebo-controlled trial designed to examine whether 8 weeks of Cistanche deserticola supplementation, when combined with a standardized anaerobic training program, can improve anaerobic exercise performance, recovery, and selected body composition outcomes in young adult men with different athletic training levels. Participants will be assigned to receive either Cistanche deserticola extract or a matched placebo while completing the same supervised anaerobic training program. The study will assess changes in anaerobic performance, including Wingate test outcomes and jump performance, as well as recovery-related indicators such as blood lactate, creatine kinase, malondialdehyde, testosterone, cortisol, and the testosterone-to-cortisol ratio. Body composition outcomes, including body fat percentage and skeletal muscle mass, will also be evaluated. The purpose of this study is to determine whether Cistanche deserticola supplementation provides additional benefits beyond training alone, and whether these effects differ between highly trained and recreationally trained participants.

The goal of this clinical trial is to investigate the acute effects of immersive virtual reality (VR)-based exergaming combined with transcranial direct current stimulation (tDCS) on executive functions in healthy older adults. The main questions it aims to answer are: * Does VR-based exergaming combined with tDCS improve executive function performance in healthy older adults compared with a control condition? * Do single interventions (tDCS alone or VR-based exergaming alone) improve executive function performance compared with the control condition? * Does the combined intervention produce greater improvements in executive function performance than either intervention alone? Researchers will compare four intervention conditions to evaluate differences in executive function performance following each session. Participants will: * Complete four intervention sessions in a randomized crossover sequence, with a washout period of at least 7 days between sessions * Receive the following intervention conditions: * sham-tDCS + VR-video * tDCS + VR-video * sham-tDCS + VR-exergaming * tDCS + VR-exergaming * Complete executive function assessments immediately after each session, including: * the Flanker task for inhibitory control * the more-odd shifting task for cognitive flexibility * the Corsi block-tapping task for working memory

Patellofemoral pain (PFP) is a common musculoskeletal condition characterized by pain around or behind the patella during activities such as stair ambulation, squatting, running, jumping, and prolonged sitting. Exercise therapy combined with patient education is considered first-line treatment, and supervised rehabilitation is commonly used to improve adherence and clinical outcomes. Telerehabilitation may increase accessibility and reduce time and travel burden, but high-quality evidence remains limited regarding whether telerehabilitation provides outcomes that are not inferior to conventional face-to-face supervised rehabilitation in individuals with PFP. This study is a randomized, assessor-blinded, non-inferiority trial designed to compare telerehabilitation with face-to-face supervised rehabilitation in individuals with patellofemoral pain. The trial will evaluate whether telerehabilitation is not inferior to face-to-face supervised rehabilitation in improving pain and knee-related function, while also examining psychological outcomes, self-satisfaction, and adherence.

Patellofemoral pain (PFP) is a common overuse injury in runners. Increased patellofemoral joint stress (PFJS) is an important biomechanical factor associated with PFP. Gait retraining, especially cadence modification, may reduce PFJS and improve symptoms, but evidence from randomized controlled trials remains limited. This study investigated whether wearable device-assisted gait retraining was more effective than education alone in reducing pain, improving function, and altering running biomechanics in female runners with PFP.

This study aims to investigate the differences in cardiovascular stress response patterns among individuals with various physical activity levels (sedentary controls and different types of athletes). By synchronously monitoring ECG, heart rate, skin sympathetic nerve activity (SKNA), blood pressure, and cardiac output, the study will characterize physiological dynamics during resting, orthostatic challenge, cold pressor stress, and maximal exercise.

What will I experience if I participate in this study? If eligible, participants will be randomly assigned by physicians to one of two study phases: the screening and baseline assessment phase, or the intervention and follow-up phase. The trial consists of three phases, each containing two phases (experimental or control, lasting 1-2 weeks). After enrollment, participants will be randomly assigned to either the Tai Chi intervention group or the walking control group. Throughout the study, participants must cooperate with physicians to complete relevant questionnaires and attend scheduled follow-up visits. What might be the benefits of participating in this study? The research team will cover all expenses for the exercise program. Participants will receive free exercise training, physiological counseling, and standardized assessments throughout the study, including follow-up sessions.

The purpose of the study is to investigate the effects of short-term braking on the motor learning and fine motor skills of healthy adults, and to analyze whether transcranial direct current stimulation can alleviate the effects of braking on motor learning and fine motor skills.

This study aimed to investigate whether six weeks of tDCS combined with lower-limb resistance training could enhance motor learning in healthy young adults and examined the persistence of any observed benefits.

The goal of this clinical trial is to investigate the effects of different intensities of transcranial direct current stimulationover primary motor cortex on motor learning in healthy adults. The main question it aims to answer is: Which intensity of tDCS can best improve motor learning? Researchers will compare 1 mA, 2 mA, and 3 mA tDCS to sham tDCS to see which intensity of tDCS is most effective in improving the ability of motor learning. Participants will be randomly divided into four groups and receive 4 different intensities of tDCS(1 mA, 2 mA, 3 mA and sham tDCS),and will be blinded to the type of tDCS they received. We hypothesized that anodal tDCS at 2 mA would produce the most substantial improvement in motor learning.

Exploring the efficacy and acceptability of exercise snacks (ES) and sprint interval training (SIT) could provide time-efficient, low-barrier alternatives for individuals, especially those who, due to 'lack of time, environment, and equipment,' struggle to meet traditional physical activity recommendations. This research aims to investigate the effects of ES and SIT, of equal exercise volume, on overweight adults.
