“…With information such as the force applied to the pedal and, thus, the generated mechanical power, professional cycling teams can validate training techniques and evaluate the influence of variables such as the cyclist's stance, the pedaling cadence, the asymmetry between forces, and other parameters of interest. Although the industry already offers equipment capable of measuring the athlete's resultant produced power, there are no models capable of providing information on the components of the applied force, so their development is restricted to research laboratories [ 4 , 5 ]. Therefore, the main goal of this study is the development of a force platform that allows the analysis of the three-dimensional components of the force applied to the crank by the cyclist during real competition conditions.…”

This report describes a new crank arm-based force platform designed to evaluate the three-dimensional force applied to the pedals by cyclists in real conditions. The force platform was designed to be fitted on a conventional competition bicycle crankset while data is transmitted wirelessly through a BluetoothTM module and also stored on a SD card. A 3D solid model is created in the SolidWorks (Dassault Systèmes SOLIDWORKS Corp.) to analyze the static and dynamic characteristics of the crank arm by using the finite elements technique. Each crankset arm is used as a load cell based on strain gauges configured as three Wheatstone bridges. The signals are conditioned on a printed circuit board attached directly to the structure. The load cell showed a maximum nonlinearity error between 0.36% and 0.61% and a maximum uncertainty of 2.3% referred to the sensitivity of each channel. A roller trainer equipped with an optical encoder was also developed, allowing the measurement of the wheel's instantaneous velocity.

“…A componente tangencial da força (Fx) atua paralelamente à superfície do pedal, enquanto que a componente normal da força (Fy) atua perpendicularmente à superfície do pedal. A partir destas duas componentes da força é possível calcular a força efetiva (FE), esta aplicada perpendicularmente ao pé-de-vela e considerada como a força geradora de propulsão da bicicleta (BROOKE, HOARE, ROSENROT & TRIGGS, 1981;CANDOTTI, 2003;HULL & WOOTTEN, 1996;SANDERSON & CAVANAGH, 1990).…”

O objetivo deste estudo foi testar uma metodologia para o ensino da técnica da pedalada do ciclismo utilizando variáveis biomecánicas para desenvolver um sistema de "feedback" visual aumentado (FVA). Participaram do estudo 19 indivíduos, sem experiência no ciclismo , divididos em grupo experimental (n = 10) e controle (n = 9). Inicialmente foi realizado um pré-teste para determinar o consumo máximo de oxigênio (VO2máx) bem como a carga de trabalho utilizada nas sessões práticas que correspondeu a 60% do VO2máx. Em seguida foram realizadas sete sessões de prática. O grupo experimental foi submetido ao FVA e o grupo controle ao "feedback" aumentado (FA). O teste de retenção mostrou um aumento de 21 % na média do índice de efetividade (IE) do grupo experimental quando comparado ao grupo controle. Os resultados mostraram que variáveis biomecánicas são apropriadas para o desenvolvimento de FVA e podem contribuir no processo de ensino-aprendizagem da técnica da pedalada do ciclismo.
