NCT05514392

Brief Summary

The study will contribute to answering the question of 'in which exercise types of single-leg and double-leg exercise protocols will affect whether fatigue occurs early or not, and muscle activations will occur. In response to this question, clinicians will prefer to focus on which type of exercise produces more muscle activation and late fatigue. Few studies have been done on single and double leg bicycle ergometers in the literature. From these studies; While examining the lactate and EMG threshold values after cycling ergometer training, another study compared the effectiveness of single and double leg cycling ergometers. In the literature, EMG and dynamic balance were not used in the comparison after single and double leg bicycle ergometer training. In this study, the effectiveness of single and double legged bicycle ergometers will be compared by looking at EMG and dynamic balance changes.

Outcome Measures

Primary Outcomes (3)

  • Superficial Electromyographic (EMG) Measurement

    In the dominant lower extremity to evaluate muscle activity, rectus femoris, surface EMG signals will be recorded with the Trigno Avanti Wireless Surface EMG System. While the participant is standing in hip neutral and knee extension, the adhesive EMG electrode will be placed on the reference motor point. Superficial EMG values will be recorded throughout the exercise. During the research, EMG will be recorded from the stimulated muscles by applying two electrodes to the skin for each muscle. The amplitude, duration and shape of the evoked muscle action potentials obtained will be reflected as a result. The amplitudes of the EMG signals will be evaluated. The method to be used when evaluating EMG signal amplitudes will be the raw EMG calculation. While evaluating the data, the computer package programs will benefit.

  • Static-Dynamic Balance Evaluation with Isokinetic Balance Device

    Static and dynamic balance performances will be evaluated using the isokinetic balance measurement system. In this system, there is a sensor in the center of the platform that detects every angular movement and sends the information directly to the computer. For the static balance test, it will be ensured that they stand on both feet and on the right/left foot with eyes open (EO) and eyes closed (EC), respectively. The arms are positioned next to the body. Between each test measurement lasting 20 seconds, approximately 40 seconds of rest will be given. For the dynamic balance test, the difficulty level of the test will be set to "20". In the test, they will be asked to circle clockwise 5 times in 60 seconds without bending their knees within the limited area on the computer screen. The Patient Record database module enables the creation of clinical cards for each case. It facilitates the comparison of each case's own tests.

  • Static Balance Evaluation with One Leg Standing Balance Test

    This test will be used to evaluate balance status in our study. During the application, the person raises one foot while standing. From this moment on, the time is kept with the help of a stopwatch. As soon as the person's foot touches the ground again, the time is stopped.If the person can stand on one leg for 30 seconds, the test is over. If the time is between 10 seconds and 5 seconds, there is an imbalance. Even if it is less than 5 seconds, there is a risk of falling.

  • Fatigue Impact Scale

    Change from baseline fatigue scale values in 30 minutes

  • Evaluation of Leg Fatigue with the Modified Borg Scale (MBS)

Study Arms (2)

Receiving Single Leg Cycling Ergometer Training

First of all, an initial warm-up will be done with 40 watts of exercise intensity for 3 minutes. Exercise will be started with 80 watts of exercise intensity and will be increased by 40 watts every 3 minutes. Cycling cadence will be determined as a pedaling speed of 80 revolutions per minute and patients will be asked to keep their dominant leg on the pedal and keep their non-dominant leg on the ground. The exercise protocol will consist of 2 sets as 15 minutes of exercise + 1 minute of break + 15 minutes of exercise. During the exercise, the heart rate and oxygen saturation of the participants will be monitored by finger pulse oximetry. EMG measurements were taken at the beginning and end of the ergometer training.

Receiving Double Leg Cycling Ergometer Training

First, a 3-minute initial warm-up will be done with an exercise intensity of 40 watts. The workout will begin with an exercise intensity of 80 watts and increase by 40 watts every 3 minutes. Cycling cadence will be determined as a pedaling rate of 80 revolutions per minute and patients will be asked to pedal with both legs. The exercise protocol will consist of 2 sets of 15 minutes of exercise + 1 minute of break + 15 minutes of exercise. During the exercise, the heart rate and oxygen saturation of the participants will be monitored by finger pulse oximetry. EMG measurements were taken at the beginning and end of the ergometer training.

Interventions

Participants will sign a consent form approved by the ethics committee. Height, weight, thigh length, leg length, foot length and kinematic foot length will be recorded before data collection. Ergometer positions will be adjusted according to participant preference. Participants will be invited to the Health Sciences University Physiotherapy and Rehabilitation Hall once. Before starting the exercise of the participants, muscle activity, balance assessment, leg fatigue will be evaluated. Participants will be made an exercise protocol. At the end of the exercise, necessary evaluations will be made again, and then the person will rest for 1 hour. After 1 hour, the exercise groups will change; Persons receiving single foot bicycle ergometer training will receive double foot bicycle ergometer training, and the group receiving double foot bicycle ergometer training will receive single foot bicycle ergometer training. Necessary evaluations will be repeated at the end of the training.
