Investigation of the Effect of Pedal Technique Training Protocol on Functional Threshold Power Test and Lower Extremity Isokinetic Power

Abstract Purpose: The objective of this study is to assess the influence of pedal technique development training regimen on functional threshold power, lower extremity knee isokinetic power, and right-left knee power ratio differences.

Methods: Twenty-three male athletes with an average age of 15-17 years in the youth division of road cycling voluntarily participated in the study. Within the scope of the study, height, body weight, body fat ratio measurements, functional threshold power, pedal analysis tests, and lower extremity knee power measurements were performed as pre-test and post-test. Athletes participated in an 8-week, two-day-per-week pedal technique development training program. Statistical analyses were planned to be carried out on the data gathered from these measurements, calculations, and tests.

About this study

The study included 24 male athletes between the ages of 15-17 who continue their sports careers at the national team level. The participants consisted of a total of 24 athletes, 12 in the training group and 12 in the control group.

The research program was carried out two days a week for 8 weeks. During this period, the experimental group received their own bicycle training programs in addition to pedal technique development training, while the control group continued their regular bicycle training only. The study was designed as an experimental research with a pre-test-post-test design and a predetermined control group. The experimental approach refers to applying the factor to be investigated under specific rules and conditions, evaluating the participants' responses, and then analyzing the data obtained.

The study was divided into three phases: pre-testing, training, and post-testing. It lasted eight weeks. During the pre-test and post-test periods, both the training and control groups underwent one week of assessments.

The ethical suitability of the study within the scope of scientific research was examined by the Presidency of the IUC Non-Interventional Clinical Research Ethics Committee, and approval was obtained with the decision letter dated 22.05.2022 and numbered E-74555795-05.01.04-392011.

Other

Pedal Technique Training Protocol This training is designed as a technical training to observe pedaling data, analyze right and left leg power ratios, and determine how they change when pedaling at various intensities and cadences

Primary outcomes

  1. Change from Baseline in Functional Threshold Power (W/kg) as Measured by Standardized Cycling Test

    Time frame: Baseline and 8 weeks

    Functional Threshold Power (FTP) will be assessed using a standardized cycling protocol on a road bike trainer. The change from baseline to post-intervention (8 weeks) will be analyzed.

Secondary outcomes

  1. Change from Baseline in Knee Extension Peak Torque at 60°/sec

    Time frame: Baseline and 8 weeks

    Knee extension peak torque will be measured at an angular velocity of 60°/sec using an isokinetic dynamometer. Changes from baseline to 8 weeks will be analyzed.

  2. Change from Baseline in Knee Flexion Peak Torque at 60°/sec

    Time frame: Baseline and 8 weeks

    Knee flexion peak torque will be measured at an angular velocity of 60°/sec using an isokinetic dynamometer. Changes from baseline to 8 weeks will be analyzed.

  3. Change from Baseline in Knee Extension Peak Torque at 180°/sec

    Time frame: Baseline and 8 weeks

    Knee extension peak torque will be measured at an angular velocity of 180°/sec using an isokinetic dynamometer. Changes from baseline to 8 weeks will be analyzed.

  4. Change from Baseline in Knee Flexion Peak Torque at 180°/sec

    Time frame: Baseline and 8 weeks

    Knee flexion peak torque will be measured at an angular velocity of 180°/sec using an isokinetic dynamometer. Changes from baseline to 8 weeks will be analyzed.
