Can Guided Discovery Instruction Be Detrimental to Children with Different Levels of Aquatic Competence in Infancy?

Repetitive practice can become an exploratory activity where instruction and discovery are linked, allowing instruction and guidance through tasks that help to construct and acquire the knowledge and skills that make up the content. (1) Background: The aim of the study was to show how a teaching method based on guided discovery would affect the teaching of children's aquatic competence in schoolchildren with different levels of competence. (2) Methods: An observational study was conducted with 385 schoolchildren (195 boys and 189 girls) aged 3-5 years belonging to a charter kindergarten, using an Instrument for the Measurement of Aquatic Competence in Children (SMACC) consisting of 17 items grouped into three dimensions: socio-affective, cognitive, and motor.

Variables e instrumentos para evaluar la salud mental en nadadores de competición: una revisión narrativa.

Background: Mental health issues are becoming increasingly prevalent among elite athletes, and during the Tokyo 2020 Olympic Games, this issue became a pressing concern. In particular, several athletes complained about their mental health in relation to the highly demanding demands of their sport. High-performance swimming exposes athletes to a variety of stressors due to the physical, technical and mental demands of the sport.

Effect of the Skill, Gender, and Kick Order on the Kinematic Characteristics of Underwater Undulatory Swimming in the Dorsal Position.

Backstroke swimmers display the greatest contribution of underwater kicking during the swimming race distances, but, surprisingly, there is little evidence of how kicking kinematics in the dorsal position should be performed. The aim of the present study was to examine the kinematic characteristics of competitive swimmers during underwater undulatory swimming in the dorsal position, with special attention to the swimmers' gender, the level of skill, and kick order. Forty-one national-level swimmers (27 females and 14 males) were filmed from an underwater lateral view while performing a 25-m backstroke from a push start, and they were divided into fast and slow groups according to their kicking velocity.

Kinematic analysis of the underwater glide phase during the push-off in competitive swimmers.

The aim of the study was to analyze the kinematic parameters of the push-off start during the underwater glide in competitive swimmers. 74 swimmers participating in the Spanish Championships were filmed and analyzed by DLT-2D photogrammetry after the push-off start in crawl, backstroke and butterfly. Between genders there were differences in distance and speed.

Bibliometric study on artistic swimming.

Introduction: The objective of this paper is to study the research trends in the sport modality of artistic swimming and to analyse the scientific production regarding this sport.

Methods: Two hundred and twenty articles related to the theme were selected after a search in the PubMed, SPORTDiscus and Web of Science databases and some additional records, using the theme "synchronised swimming OR artistic swimming" up to December 2022. The variables scrutinized were the following: (1) title, (2) discipline, (3) type, (4) sample size and (5) sporting level.

Kinematic changes in the undulatory kicking during underwater swimming.

The contribution to total race distances of underwater undulatory swimming (UUS) is increasing at the elite level. However, little is known about the technical modifications during underwater swimming. In the present research, the aim was to compare the kinematic characteristics of competitive swimmers between the first and last kick of UUS.

Kinematic Analysis of the Underwater Undulatory Swimming Cycle: A Systematic and Synthetic Review.

The increase of low-cost technology for underwater filming has made quantitative analysis an affordable resource for swimming coaches on a frequent basis. In this context, a synthesis of the kinematic determinants of underwater undulatory swimming (UUS) seems to be lacking. The aim of the present study was to synthesise the scientific evidence on the kinematic characteristics of competitive swimmers during UUS and the main kinematic determinants of UUS performance, as well as to summarise the main methodological considerations for UUS kinematic analysis.

Effect of breakout phase on the stroke kinematics and coordinative swimming variables.

The first complete upper and lower limbswimming cycle after the underwater segment of start and turns represents the breakout phase in competitive swimming. The aim of the present research was to examine the effect of the breakout movements on the stroking variables and coordinative patterns of competitive swimmers. Thirty-three national-level male swimmers performed 4 x 25 m maximal efforts (one of each stroke in random order) from a push start and were recorded by two sequential cameras in the sagittal plane.

How Mixed Relay Teams in Swimming Should Be Organized for International Championship Success.

The primary goal of the present research was to determine the order of swimmers on a mixed relay team that would ensure the best performance in the Fédération Internationale de Natation (FINA) World Championships held in Kazan (Russia, 2015), Budapest (Hungary, 2017), and Gwangju (South Korea, 2019). The data were obtained from database websites for the 4 × 100 m freestyle and 4 × 100 m medley official results, including 660 records from 188 entries of finals and 472 preliminary events. The results showed that the fastest swimmers (according to their best season times) were located primarily in the first or second positions of the freestyle relay.

An Updated Review of the Epidemiology of Swimming Injuries.

Objective: To carry out a systematic review to update the scientific evidence on the incidence and prevalence of injuries in the swimming discipline, as well as the location, type, and mechanism of the injuries, and to assess whether studies are meeting methodological recommendations for data collection and injury surveillance. TYPE: Analytical-Systematic review.

Literature Survey: The databases of PubMed and Sportdiscus were used to search for studies that describe the epidemiology of injuries in adult swimmers between 2010 and March 2020.

The Transition from Underwater to Surface Swimming During the Push-off Start in Competitive Swimmers.

The objective of the present study was to analyze (based on gender and the style of swimming) the kinematic parameters of the transition phase between underwater swimming and surface swimming after the push-off start in competitive national swimmers. Seventy-four swimmers participating in the Spanish Swimming Championships were filmed and analyzed by DLT-2D photogrammetry during the start with the push-off in crawl, backstroke and butterfly styles. Between genders there were small differences in the distance and speed of transition.
