This study aimed to: (i) verify the within-subject effect of the dominant and non-dominant upper limb propulsion during consecutive arm-pulls through discrete (average) and continuous analysis (SPM), and; (ii) compare young swimmers' propulsion between both upper limbs through discrete (average) and continuous analysis (Statistical Parametric Mappi...

The aim of this study was to compare the swimming velocity in front-crawl between age-group swimmers using discrete variables against Statistical Parametric Mapping (SPM). The sample consisted of 30 young male swimmers divided into three groups (each with 10 swimmers) based on their age (group #1: 13.60 ± 0.84 years; group #2: 15.40 ± 0.32 years; g...

Evidence on the role of propulsion compared to drag in swimming, based on experimental settings, is still lacking. However, higher levels of propulsion seem to lead to faster swimming velocities. The aim of this study was to understand the variation in a set of kinematic and kinetic variables between two swimming sections and their relationship to...

Background Smart technology, such as wearables, applied to sports analysis is essential for the performance enhancement. New technological equipment can promote the interaction between researchers, coaches, and athletes, facilitating the information exchange in real-time. Objective The aim of this study was to present a new wearable equipment (Sma...

Understanding the difference in each upper limb between age groups can provide deeper insights into swimmers’ propulsion. This study aimed to: (1) compare swimming velocity and a set of kinematical variables between junior and juvenile swimmers and (2) compare the propulsion outputs through discrete and continuous analyses (Statistical Parametric M...

Introduction: In swimming, it is necessary to understand and identify the main factors that are important to reduce active drag and, consequently, improve the performance of swimmers. However, there is no up-to-date review in the literature clarifying this topic. Thus, a systematic narrative review was performed to update the body of knowledge on a...

The aim of this study was to: (i) characterise the stroke kinematics’ stability of the male swimmers competing in the four 50 m events at the 2021 European Championships, and; (ii) understand the speed–time relationship in the four race events. All male swimmers who participated in the 50 m events (backstroke: 78 swimmers; breaststroke: 79 swimmers...

This study aimed to (i) compare the race performance of the swimmers with better performances and poorer performances during all sections of a 100 m freestyle event and (ii) compare stroke kinematics variables between tiers and analyse their stability in each tier. The sample was composed of 88 swimmers that participated in the 100 m Freestyle even...

Background/objective This study aimed to examine the effects of eight weeks of dry-land strength combined with swimming training on the development of upper and lower body strength, jumping ability, and swimming performance in competitive sprinter swimmers. Methods Twenty (14 men and 6 women) university swimmers of national-level (age: 20.55 ± 1.7...

Este trabalho teve como objetivo caraterizar e definir um perfil normativo para os jogadores de elite nacional na modalidade de voleibol, nas suas diferentes posições em campo. Para o efeito participaram 122 jogadores masculinos de 14 equipas da 1ª e 2ª divisões nacionais (idade: 24.52 ± 5.78 anos, massa corporal: 80.07 ± 9.64 kg, altura: 186.28 ±...

The aim of the current study was to characterize the neuromuscular jumping performance and upper-body horizontal power of elite and subelite volleyball players. In addition, those neuromuscular performances were compared between field positions. One hundred twenty-two male volleyball players participated in the study: 83 elite players (mean ± SD: 2...

Swimmers are tested in both dry land and specific swim protocol. The purpose of the present study was to verify the relationships between dry-land exercises and sprint swimming performance. Fifteen male college swimmers (age: 20 ± 1.46; body mass: 67.81 ± 8.04 kg; height: 177.60 ± 6.99 cm) of high-level volunteered to participate. Strength variable...
