"Estimation of an Elite Road Cyclist Mechanical Power and Energy Cost Wearing Standard and Aero Helmets: an Analytical Procedure and Numerical Simulations Approach"

O Coordenador do Departamento de Desporto do nosso Instituto, o Prof. Doutor Pedro Forte, em parceria com outros investigadores nacionais, lançou recentemente um novo artigo científico. Com o título "Estimation of an Elite Road Cyclist Mechanical Power and Energy Cost Wearing Standard and Aero Helmets: an Analytical Procedure and Numerical Simulations Approach", o artigo científico publicado no European Journal of Human Movement, tem o objetivo avaliar o efeito de diferentes capacetes no rendimento de ciclistas na posição de cronómetro.

Abstract
The  aim  of  this  study  was  to  assess  and  compare  by  numerical  simulations  and analytical  models  the  resistive  forces,  mechanical  power,  energy  cost  and  velocity  using  two different types of road helmets (standard vs aero road helmet). An elite cyclist was scanned on the  racing  bicycle,  wearing  his competition  gear  and  helmets. Numerical  simulations  by Computational  Fluid  Dynamics  were  carried-out  at  11.11  m/s  (40  km/h)  and  20.83  m/s  (75 km/h)  to  extract  the  drag  force. The  mechanical  power  and  energy  cost  were  estimated  by analytical  procedures. The drag  forces  were  between  9.93  N  and  66.96  N  across  the  selected speeds and helmets. The power to overcome drag were 182.19 W and 1121.40 W. The total power lower and higher values were 271.05 W and 1558.02 W. The energy cost estimation was between 106.89 J/m  and  381.40  J/m  across  the  different  speeds  and  helmets. The  standard  helmet imposed higher drag and demanded more.
