Allergy-compatible symptoms among federated swimmers in Portugal
Swimmers are chronically exposed to water disinfection by-products (commonly from chlorination) and to indoor air conditions that may aggravate allergic and respiratory symptoms. Evidence is robust for elite cohorts, but competitive swimmers outside Olympic settings remain understudied. We conducted a cross-sectional, anonymous online survey among Portuguese competitive swimmers, officially registered with the national federation, aged 16 years o…
Rating of perceived exertion in continuous sports
Introduction: Rating of perceived exertion (RPE) is widely used for assessing training load in sports due to its validity, simplicity, and utility. Despite its broad application, the diverse contexts and methodologies in which it is used warrant a comprehensive review of the existing evidence. Objective: This scoping review aims to map the current evidence on the use of RPE, focusing on its application, measurement methods, and reliability across…
Transforming tennis with artificial intelligence
The aim of this study was to conduct a scoping and bibliometric review of articles using artificial intelligence (AI) in tennis. The analysis covered various aspects of tennis, including performance, health, match results, physiological data, tennis expenditure, and prize amounts. Articles on AI in tennis published until 2024 were retrieved from the Web of Science database. A total of 389 records were screened, and 108 articles were retained for …
Evaluando la aerodinámica de un ciclista sin discapacidad y un ciclista con amputación de hombro mediante dinámica de fluidos computacional
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 increments of 1 m/s) with the fluent code.Th…
Effects of a 6-week on-court training program on the International Tennis Number (ITN) and a range of physical fitness characteristics in young tennis players
The study aimed to (i) verify the effects of an on-court training program on the International Tennis Number (ITN) of young tennis players, as well as on a set of change of direction, linear sprint, and maximal oxygen uptake (VO2max) variables, and (ii) identify the main predictors of ITN. The sample consisted of 20 young male tennis players (mean age, 13.62 ± 0.23 years). Players underwent a 6-week on-court training program. The ITN and a number…
Exploring the Relationship between Fibromyalgia-Related Fatigue, Physical Activity, and Quality of Life
Physical activity does not mediate the relationship between fatigue and quality of life. However, the results also show that the fatigue dimensions associated with fibromyalgia had a negative and significant association with physical and mental health indicators in both samples. Thus, patients with FM with higher scores on fatigue-related symptoms might suffer more from physical and mental health, both of which are related to quality of life
Maximum Isometric and Dynamic Strength of Mixed Martial Arts Athletes According to Weight Class and Competitive Level
Mixed martial arts (MMA) athletes must achieve high strength levels to face the physical demands of an MMA fight. This study compared MMA athletes' maximal isometric and dynamic strength according to the competitive level and weight class. Twenty-one male MMA athletes were divided into lightweight professional (LWP; n = 9), lightweight elite (LWE; n = 4), heavyweight professional (HWP; n = 4), and heavyweight elite (HWE; n = 4). The handgrip and …
The Co-Occurrence of Satisfaction and Frustration of Basic Psychological Needs and Its Relationship with Exercisers’ Motivation
Although the relationship between both need frustration and, particularly, need satisfaction and different motivational regulations for exercise has been widely examined in the literature, little is known about the co-occurrence of both need satisfaction and need frustration in the exercise context. Grounded in self-determination theory, the present study aimed to examine the effects of both need satisfaction and frustration on motivational regul…
O papel do divertimento e das determinantes motivacionais na persistência da prática de exercício físico
Como objetivo deste trabalho, definiu-se analisar os efeitos indiretos de determinantes motivacionais no divertimento e na persistência em praticantes de exercício físico regular. Participaram ao todo 967 praticantes de exercício em ginásio e health clubs, com idades compreendidas entre 18 e 65 anos (M=45,08; DP=13,76). Todos os participantes tinham mais de 6 meses de experiência regular em exercício físico. Os participantes preencheram ao todo q…
Monitoring Master Swimmers’ Performance and Active Drag Evolution along a Training Mesocycle
This study aimed to analyze the effects of a swimming training mesocycle in master swimmers' performance and active drag. Twenty-two 39.87 ± 6.10 year-old master swimmers performed a 25 m front crawl at maximal intensity before and after a typical four-week training mesocycle. Maximum, mean and minimum speeds, speed decrease and hip horizontal intra-cyclic velocity variation were assessed using an electromechanical speedometer, and the active dra…
Novel Resistance Training Approach to Monitoring the Volume in Older Adults
We analyzed the effects of velocity-monitored resistance training (RT) with a velocity loss of 20% on strength and functional capacity in institutionalized older adults. Thirty-nine participants (78.8 ± 6.7 years) were divided into a control group (CG; n = 20) or an RT group (n = 19). Over 10 weeks, the RT group performed two sessions per week, and the mean velocity of each repetition was monitored in the leg-press and chest-press exercises at 40…
Ultimate Full Contact
Fight analysis produces relevant technical-tactical information. However, this knowledge is limited in hybrid full-contact combat sports. Therefore, this study aimed to characterize the results of the fights' outcomes through the winners at the World Ultimate Full Contact (WUFC) Championships between 2008 and 2017. Methods: 170 combats between senior male fighters (master class) from 38 countries were observed; all fight outcome methods, their oc…
The Drag Crisis Phenomenon on an Elite Road Cyclist—A Preliminary Numerical Simulations Analysis in the Aero Position at Different Speeds
The drag crisis phenomenon is the drop of drag coefficient (Cd) with increasing Reynolds number (Re) or speed. The aim of this study was to assess the hypothetical drag crisis phenomenon in a sports setting, assessing it in a bicycle–cyclist system. A male elite-level cyclist was recruited for this research and his competition bicycle, helmet, suit, and shoes were used. A three-dimensional (3D) geometry was obtained with a 3D scan with the subjec…
The Effect of Ballistic Exercise as Pre-Activation for 100 m Sprints
The benefits of warm-up in sports performance has received a special interest in the current literature. However, there is a large gap of knowledge about the tasks to be performed, specifically in the real competitive environment. The purpose of the study was to verify the acute effects of a warm-up including ballistic exercises in 100 m running performance. In addition, a second 100 m trial was assessed to better understand the warm-up effects i…
Effects of Backpacks on Ground Reaction Forces in Children of Different Ages When Walking, Running, and Jumping
Backpacks for transporting school loads are heavily utilized by children, and their mechanical advantages have been allowing children to transport heavy loads. These heavy loads may increase ground reaction forces (GRFs), which can have a negative effect on joints and bone health. The aim of this study was to investigate the effect of backpacks on the GRFs generated by children during walking, running, and jumping. Twenty-one children from the fi…
