About this study
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.
Read the detailed description
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.
