Brief Summary

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.

Conditions

Isokinetic Test; Cyclists; Performance Enhancement

Keywords

Pedal technique, Bicycle, Isokinetic power, Assymetry, Functional threshold power

Outcome Measures

Primary Outcomes (1)

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

  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.

  Baseline and 8 weeks

Secondary Outcomes (4)

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

  Baseline and 8 weeks

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

  Baseline and 8 weeks

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

Study Arms (2)

experimental group - Pedal Technique Training

ACTIVE COMPARATOR

Participants will receive an 8-week pedal technique training protocol in addition to their regular cycling training.

Other: Participants will receive an 8-week pedal technique training protocol in addition to their regular cycling training.
