Comparison Of Injuries To The Anterior Cruciate Ligament In Male Soccer And Football Athletes And The Effect Of Varying Rehabilitation On Recovery Time, Matthew Moraw

Undergraduate Honors Thesis Collection

Injuries are commonplace when a sport involves high levels of physical contact and quick movements. Athletes often strain or tear muscles and sprain ligaments when they are putting above normal levels of stress on the connection points through their explosive motions and high force collisions. Two sports where this is particularly common are soccer and football. Due to the high levels of running and cutting in both sports, lower body injuries, particularly to the knee are some of the most common injuries that occur. The purpose of this study was to take a retrospective look at ACL tears in college …

The Prevalence Of Red-S Among College Athletes, Johnny Nguyen

Graduate Research Showcase

Relative Energy Deficiency in Sports (RED-S) is a phenomenon established by the International Olympic Committee to expand on the previously known condition as the female athlete triad, to include male athletes. Relative Energy Deficiency in Sports is a physiological functioning impairment due to athletes with low energy availability. Low energy occurs when athletes expend more energy (calorie burn with activity) than they consume (daily caloric intake) for an extended period. Leading to alter or impaired physiological function. College is a period where individuals gain their independence. Collegiate student-athletes are learning to juggle multiple aspects of their life. Along with excelling …

Study On The Efficiency Of Advanced Pressing In The Premier League, Sorin Brîndescu, Francisc-Remus Datcu, Ionuț-Alexadru Buda

Baltic Journal of Health and Physical Activity

Background: Advanced pressing is a tactical relationship which consists of a joint effort which players undertake to win back possession as high up the pitch as possible. It comes as a direct counter to slow build-up styles like the tiki-taka and has existed, historically, for decades. The best examples from history can be Ajax and Feyenoord in the 1970s, as well as the Dutch national team from the same period. In these days, some of English teams use this tactical relationship with the desire to recover the ball as quickly as possible. Material and Methods: In order to analyze the …

Hip And Knee Joint Angle Patterns And Kicking Velocity In Female And Male Professional Soccer Players: A Principal Component Analysis Of Waveforms Approach, Archit Navandar, Kristof Kipp, Enrique Navarro

Exercise Science Faculty Research and Publications

This study used principal component analysis (PCA) of waveforms to extract movement patterns from hip and knee angle time-series data; and determined if the extracted movement patterns were predictors of ball velocity during a soccer kick. Twenty-three female and nineteen male professional soccer players performed maximal effort instep kicks while motion capture and post-impact ball velocities data were recorded. Three-dimensional hip and knee joint angle time-series data were calculated from the beginning of the kicking leg’s backswing phase until the end of the follow-through phase and entered into separate PCAs for females and males. Three principal components (PC) (i.e., movement …

Journal for Sports Neuroscience

Abstract.

Introduction

Sports related concussion, also considered mTBI, has remained in the public eye due to heightened fear concerning playing football and other collision based sports. Concussion prevention, as well as rehabilitating the brain after a concussion, is a high priority for many sports medical practitioners as well as for athletes. For these reasons, researchers associated with the American Athletic Conference (AAC) have surveyed concussion incidence in football. One of the AAC teams engaged in regular neurovisual training (NVT) and concluded this training program is associated with faster return to play post-injury in this observational cohort study.

Acute Physiological Responses To High-Intensity Resistance Circuit Training Vs. Traditional Strength Training In Soccer Players, Cristian Marín-Pagán, Anthony J. Blazevich, Linda H. Chung, Salvador Romero-Arenas, Tomás T. Freitas, Pedro E. Alcaraz

Research outputs 2014 to 2021

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. The aim of this study was to evaluate and compare the cardiorespiratory and metabolic responses induced by high-intensity resistance circuit-based (HRC) and traditional strength (TS) training protocols. Ten amateur soccer players reported to the laboratory on four occasions: (1) protocol familiarization and load determination; (2) maximal oxygen consumption test; (3) and (4) resistance training protocols (HRC and TS), completed in a cross-over randomized order. In both protocols, the same structure was used (two blocks of 3 sets × 3 exercises, separated by a 5-min rest), with only the time between consecutive …

Effects Of High-Intensity Position-Specific Drills On Physical And Technical-Skill Performance In Young Soccer Players, Cao Cuong Le

Theses: Doctorates and Masters

Soccer is the most widely played sport in the world, and physical preparation for soccer players has been extensively researched over the years. As the average intensity of a soccer match is close to 80-90% of maximal heart rate (HRmax), it is necessary to train at or above this intensity. Thus, high-intensity interval running and small-sided games are often used to improve aerobic capacity and repeated sprint ability (RSA). However, neither of these approaches consider positional variations in the frequency and type of specific technical skills required in real match situations. Thus, the purpose of this study was to investigate …
