Recommendations for Physical Exercise as a Strategy to Reduce Problematic Use of the Internet and Digital Devices
Excessive use of the Internet and digital devices has become a growing public health concern, contributing to mental health issues, sedentary lifestyles, and decreased well-being. Despite the increasing prevalence of digital overuse, there is no consensus on effective interventions to mitigate its impact. This article aimed to provide an updated perspective on current research into problematic use of digital devices and the Internet, and to explo…
Smartphone and Social Network Usage is Influenced by Physical Activity and Self-Esteem
Smartphone Addiction (SA) and Social Network Addiction (SNA) can have a variety of negative consequences so the identification of variables that could modulate these digital addictions may be key to prevent them. The aim of this study was to analyse the associations between physical activity (PA), self-esteem, SA and SNA in Spanish-speaking young adults. A correlational and comparative study was conducted with 372 Spanish-speaking participants ag…
Relationship between muscle power, muscle volume and limb length in healthy male and female adolescents
Objective Muscle power is essential for the activities of daily living. Muscle power production depends on numerous factors such as muscle size and length, muscle architecture and fiber type and varies with age during growth. The association between muscle power output during a jump and lower limb muscle volume and length in adolescents is largely unknown. This study determined the relationships between muscle power developed during a countermove…
Effects of a 10-week athletic performance program on match performance variables in male professional football players
Introduction The aim of this study was to evaluate the effect of an Athletic Performance Program (APP), implemented as a complement to the usual training routines of a professional football team, on match performance variables in professional football players. The APP was designed to target mobility, stability, strength, multidirectional and sprint skills, which are critical for performance during competitive matches. Methods A prospective quasi-…
Effects of Football Training and Match-Play on Hamstring Muscle Strength and Passive Hip and Ankle Range of Motion during the Competitive Season
Deficits in hamstring muscle strength and in hip range of motion (ROM) have been considered risk factors for hamstring muscle injuries. However, there is a lack of information on how chronic exposure to regular football training affects hamstring muscle strength and hip ROM. The aim of this study was to examine the longitudinal effect of football training and competition during a complete season on hamstring muscle strength and hip ROM in footbal…
LaLiga Lockdown
The first division of Spanish professional football ( LaLiga ) was suspended for 12 weeks as part of the policies enforced by health authorities during the first wave of COVID-19. During this period, players were confined to home for 8 weeks, followed by a club-based retraining period of 4 weeks. Afterwards, LaLiga's teams completed 11 matches, with approximately 3 days of recovery between matches, to finish the competition. The aim of this inves…
Preliminary Research towards Acute Effects of Different Doses of Caffeine on Strength–Power Performance in Highly Trained Judo Athletes
Although several previous studies examined the effect of pre-exercise caffeine ingestion on judo-specific performance, the optimal dose of caffeine to maximise the ergogenic effects for judoka is not clear. The main purpose of this study was to analyse the effects of oral administration of 3 and 6 mg/kg of caffeine on a battery of physical tests associated with judo performance. Ten highly trained national-level judoka (6 men and 4 women, age: 24…
Injury Incidence Increases after Covid-19 Infection
Background: The SARS-CoV-2 virus disease has caused numerous changes in sports routines in the last two years, showing the influence on an increase in sports injuries. The aim of this study was to prospectively analyze the incidence and characteristics of injuries in male professional football players diagnosed with COVID-19 when they return to play after recovering from this illness. Methods: Injury characteristics of professional male football …
Key Factors Associated with Adherence to Physical Exercise in Patients with Chronic Diseases and Older Adults
Physical inactivity is a major concern and poor adherence to exercise programs is often reported. The aim of this paper was to systematically review published reviews on the study of adherence to physical exercise in chronic patients and older adults and to identify those adherence-related key factors more frequently suggested by reviews for that population. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline…
Pacing Strategies of 1500 m Freestyle Swimmers in the World Championships According to Their Final Position
In 1500 m freestyle swimming races, pacing is generally represented by a parabolic or U-shaped curve indicating that swimming velocity is greatest at the start and the last laps of the race while swimmers maintain an even pace through the middle section of the race. However, there is no information to determine if 1500 m race winners select pacing different to other, less successful swimmers within the same competition. Therefore, this investigat…
Race Performance Prediction from the Physiological Profile in National Level Youth Cross-Country Cyclists
Cross-country mountain biking is an Olympic sport discipline with high popularity among elite and amateur cyclists. However, there is a scarcity of data regarding the key determinants of performance, particularly in young cross-country cyclists. The aim of this study was to examine the physiological profile of youth national-level cross-country cyclists and to determine those variables that were able to best predict the performance in an official…
Eccentric Hamstring Muscle Strength during Home Confinement Due to the Covid-19 Pandemic, and Football Competition Resumption in Professional Football Referees
The COVID-19 pandemic has produced a major disruption for professional football leagues that has affected the physical preparation of both football players and referees. In Spain, health authorities decreed home confinement for eight weeks, supressing the normal training routines of professional referees. After home confinement, referees had four weeks to retrain as the national football league was set to resume matches to complete the 11 games r…
Influence of Football Match-Play on Isometric Knee Flexion Strength and Passive Hip Flexion Range of Motion in Football Referees and Assistant Referees
The aim of this study was to examine the acute effect of officiating a football (soccer) match on isometric knee flexion strength and passive hip flexion range-of-motion (ROM) in referees and assistant football referees. Twelve referees (25.3 ± 3.3 years) and twenty-three assistant referees (25.1 ± 4.8 years) underwent measurements on isometric knee flexion strength and passive hip flexion ROM before and after officiating an official football mat…
Sport-Specific Use of Doping Substances
Background: In recent years, there has been a solid effort across all sports organizations to reduce the prevalence and incidence of doping in sport. However, the efficacy of current strategies to fight against doping might be improved by using anti-doping polices tailored to the features of doping in each sport. Objectives: The aim of this investigation was to analyze the substances more commonly found in doping control tests in individual and t…
Influence of Players’ Maximum Running Speed on the Team’s Ranking Position at the End of the Spanish LaLiga
The maximum running speed that a football player can attain during match play has become one of the most popular variables to assess a player's physical talent. However, the influence of a player's maximum running speed on football performance has not yet been properly investigated. The aim of this study was to determine the influence of a player's peak/maximum running speed on the team's ranking position at the end of a national league. A second…
