Race analysis in swimming: understanding the evolution of publications, citatio...
Morais, J.E.; Barbosa, Tiago M.; Arellano, Raúl; Silva, A.J.; Sampaio, Tatiana; Oliveira, João P.; Marinho, D.A.The aim of this study was to conduct a scoping and bibliometric review of swimming articles related to race analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify relevant studies. Articles on race analysis in swimming published between 1984 and December 31, 2023 were retrieved from the Web of Science database. 366 records were screened and a t...
Assessing the aerodynamics of an able-bodied cyclist and a shoulder-amputee cyc...
Forte, Pedro; Marinho, D.A.; Neiva, Henrique P.; Sampaio, Tatiana; Teixeira, José Eduardo; Branquinho, Luís; Silva, A.J.; Monteiro, A.M.This study aimed to analyse the aerodynamics by numerical simulations with computer fluid dynamics of an ablebodied cyclist and a shoulder-amputee cyclist. An elite cyclist volunteered for this research; the cyclist was scanned with his competition gear and bicycle and the able-bodied and shoulder amputee 3D cyclists models were created. Numerical simulations were conducted between 1 m/s and 13 m/s (with increm...
Resultant equations for training load monitoring during a standard microcycle i...
Teixeira, José Eduardo; Forte, Pedro; Ferraz, Ricardo; Branquinho, Luís; Morgans, Ryland; Silva, A.J.; Monteiro, A.M.; Barbosa, Tiago M.Applying data-reduction techniques to extract meaningful information from electronic performance and tracking systems (EPTS) has become a hot topic in football training load (TL) monitoring. The aim of this study was to reduce the dimensionality of the internal and external load measures, by a principal component approach, to describe and explain the resultant equations for TL monitoring during a standard in-se...
The drag coefficient variations across different speeds in able-bodied, transra...
Forte, Pedro; Morais, J.E.; Branquinho, Luís; Neiva, Henrique P.; Monteiro, A.M.; Barbosa, Tiago M.; Silva, A.J.; Marinho, D.A.Drag crisis has been described as a drop in the drag coefficient (Cd). This procedure was lately assessed in able-bodied cyclists in time trial position by computational fluid dynamics (CFD). Therefore, the aim of this study was to assess the phenomenon of the drag crisis by computer fluid dynamics in transradial and transtibial amputee cyclists in the upright position. A male elite-level cyclist was recruited ...
Agreement between different methods to measure the active drag coefficient in f...
Morais, J.E.; Barbosa, Tiago M.; Garrido, Nuno D.; Cirilo-Sousa, Maria S.; Silva, A.J.; Marinho, D.A.The aim of this study was to analyze the agreement of the active drag coefficient measured through drag and propulsion methods. The sample was composed of 18 swimmers (nine boys: 15.9 ± 0.9 years; nine girls: 15.3 ± 1.2 years) recruited from a national swimming team. The velocity perturbation method was used as the drag measurement system and the Aquanex system as the propulsion system. For both sexes combined,...
Profiling of elite male junior 50 m freestyle sprinters: understanding the spee...
Morais, J.E.; Barbosa, Tiago M.; Silva, A.J.; Veiga, Santiago; Marinho, D.A.The aim of this study was to (1) analyze and compare the race performance and stability between the fastest and slowest male swimmers during the 50 m freestyle event, and (2) to understand the speed-time relationship in this race. The performances (start, clean swim, and finish) of 86 swimmers (divided into two tiers: best and poorest performances) who competed in the 50 m freestyle event in the 2019 long cours...
Integrating physical and tactical factors in football using positional data: a ...
Teixeira, José Eduardo; Forte, Pedro; Ferraz, Ricardo; Branquinho, Luís; Silva, A.J.; Monteiro, A.M.; Barbosa, Tiago M.Positional data have been used to capture physical and tactical factors in football, however current research is now looking to apply spatiotemporal parameters from an integrative perspective. Thus, the aim of this article was to systematically review the published articles that integrate physical and tactical variables in football using positional data. Methods and Materials: Following the Preferred Reporting ...
Effects of chronological age, relative age, and maturation status on accumulate...
Teixeira, José Eduardo; Alves, Ana Ruivo; Ferraz, Ricardo; Forte, Pedro; Leal, Miguel; Ribeiro, Joana; Silva, A.J.; Barbosa, Tiago M.; Monteiro, A.M.The aims of this study were 1) to analyze the influence of chronological age, relative age, and biological maturation on accumulated training load and perceived exertion in young sub-elite football players and 2) to understand the interaction effects amongst age grouping,maturation status, and birth quartiles on accumulated training load and perceived exertion in this target population. A 6-week period (18 trai...
The Association between external training load, perceived exertion and total qu...
Teixeira, José Eduardo; Forte, Pedro; Ferraz, Ricardo; Leal, Miguel; Ribeiro, Joana; Silva, A.J.; Barbosa, Tiago M.; Monteiro, A.M.Moderate to very large correlation between internal training load, external training load, and recovery status have been reported in elite youth football. However, little is known about subelite youth football training environments. Objective: The purpose of this study was to assess the association between training load and recovery status in young subelite football players. Methods: Twenty under-15, twenty und...
Weekly training load across a standard microcycle in a sub-elite youth football...
Teixeira, José Eduardo; Branquinho, Luís; Ferraz, Ricardo; Leal, Miguel; Silva, A.J.; Barbosa, Tiago M.; Monteiro, A.M.; Forte, PedroCompensatory training sessions have been highlighted as useful strategies to solve the differential weekly training load between the players’ starting status. However, the influence of the players’ starting status is still understudied in sub-elite youth football. Thus, the aim of this study was to compare the weekly training load on a standard microcycle in starters and non-starters of a sub-elite youth footba...
