Velocity-Based Training—A Critical Review, Stuart Guppy, Kristina Kendall, G. Gregory Haff

Research outputs 2022 to 2026

Velocity-based training (VBT) is an increasingly popular programming strategy used by strength and conditioning professionals to develop their athlete's ability to express force rapidly. To implement the varying forms of VBT effectively within their training regimes, strength and conditioning professionals need to understand the strengths and weaknesses of strategies, such as predicting 1 repetition maximum using the load-velocity profile, modulating training loads using the load-velocity profile, and controlling training volume using the magnitude of velocity-loss. The aim of this review was to highlight these strengths and weaknesses and then provide practical examples of when each programming strategy may be most …

PAPE is the phenomenon where acute improvements in power production in light loaded movements occur post near maximal loaded muscle contraction. PAPE may be induced with VL where resistance in the form of chains or bands is added to the bar as it displaces in the concentric phase. Participants were American football players from a variety of field positions (n=12, height =188 ± 0.01 cm, total body mass = …

Directions Of Attack And Their Effectiveness Of Male Judo Medalists At The Olympic Competitions., Amar Ait Ali Yahia

Baltic Journal of Health and Physical Activity

Introduction: To perform a technical action, the elite judo athlete examines the direction of attack relative to the opponent's body position. This study aimed to analyze and compare the most frequent and effective attack directions carried out by male Olympic medalists. Materials and Methods: A sample of 112 male medalists performed 3,664 attacks in four Olympic tournaments (2004–2016). ANOVA (one factor) determined inter and intra-Olympic comparisons, followed by the post hoc Bonferroni test (p< 0.05). Eta squared η2 and Cohen's d calculated the effect size, respectively. Results: Olympic medalists oriented their attacks principally in right forward (30.5±11.3%), left forward (29.9±10.5%), left backward (18.8±8.1%), and right backward (15.8±6.1%). The effectiveness of right forward (25.7±13.1%) and left forward (26.2±12.5%) dominates left backward (20.5±10.1%) and right backward (15.5±9.7%), respectively. In terms of frequencies and effectiveness, the contribution of secondary directions is negligible. Conclusions: Attacking in eight orientations made the defense vulnerable. Beside the uncertainty and unpredictability, they created more points of imbalance to overcome defensive issues.

Effects Of Velocity-Based Training And Resistance Training On Acute Recovery Based On Sport-Specific Performance In Soccer Players, Viorel Cristian Ravar Ladislau

Student Theses and Dissertations

This study aimed to examine the effects of velocity-based training (VBT) and resistance training (RT) on acute recovery, as determined by sport-specific performance (SSP). Twenty experienced male soccer players completed five training sessions, including VBT and RT, with sport-specific training (SST) tests conducted after each session. Statistical analysis revealed significant differences (p < 0.05) in performance between VBT and RT for all six SST tests. VBT resulted in superior performance in the 30-meter dash (p < 0.0001), vertical jump (p < 0.0001), double leg bounds (p = 0.001), 505-agility drill (p < 0.0001), zigzag sprint and shuffle drill (p < 0.0001), and 5-10-15-meter shuttle run (p < 0.0001) tests. These findings support the hypothesis that VBT can lead to superior SSP outcomes compared to traditional RT in male soccer players. Results have practical implications for strength and conditioning professionals working with soccer players to improve recovery and performance outcomes.

Assessing Blood Oxygen Level–Dependent Signal Variability As A Biomarker Of Brain Injury In Sport-Related Concussion, Evan D. Anderson, Tanveer Talukdar, Grace Goodwin, Valentina Di Pietro, Kamal M. Yakoub, Christopher E. Zwilling, David Davies, Antonio Belli, Aron K. Barbey

Center for Brain, Biology, and Behavior: Faculty Publications

Mild traumatic brain injury is a complex neurological disorder of significant concern among athletes who play contact sports. Athletes who sustain sport-related concussion typically undergo physical examination and neurocognitive evaluation to determine injury severity and return-to-play status. However, traumatic disruption to neurometabolic processes can occur with minimal detectable anatomic pathology or neurocognitive alteration, increasing the risk that athletes may be cleared for return-to-play during a vulnerable period and receive a repetitive injury. This underscores the need for sensitive functional neuroimaging methods to detect altered cerebral physiology in concussed athletes. The present study compared the efficacy of Immediate Post-concussion Assessment and …

Nutrient Supplementation For Pre- And Post Acl Operation & Rehabilitation In Female Basketball Players, Mackenzie Steele, Joshua Munoz

Department of Nutrition Student Projects

Understanding how nutrition and dietary protocols can help female athletes in the process of “returning to sport” after an anterior cruciate ligament (ACL) repair surgery should be discussed amongst interprofessional post-operational care teams. Amongst athletes, female counterparts experience ACL injuries at a higher incidence rate than males, this is due to a variety of biological factors while returning to sport at a lower rate. Due to this, it is important to analyze and evaluate the data available from sports journals on the effects diet and supplements may have on the musculoskeletal system. ACL grafts are often taken from a donating …

Reaction Time Under Limited Vision With Cognitive Challenge In Individuals With Anterior Cruciate Ligament Reconstruction, Hsuan Bonny Lu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The anterior cruciate ligament (ACL) rupture is a common sports injury. ACL reconstruction (ACLR) is a necessary treatment for individuals to return to competitive sports. However, a high rate of secondary injury occurs when individuals return to sport. Past research has shown that ACLR impairs physical performance, including reduction of force generate against the floor under the injured leg, changes in the gait pattern, and a loss of knee stability. While structural changes following ACL injury can leave the knee joint less stable, neurophysiological changes following ACL injury represent one potentially important mechanism underlying the performance deficits. Healthy individuals rely …

Center for Brain, Biology, and Behavior: Faculty Publications

Introduction: Depressive symptoms can emerge as early as childhood and may lead to adverse situations in adulthood. Studies have examined structural brain alternations in individuals with depressive symptoms, but findings remain inconclusive. Furthermore, previous studies have focused on adults or used a categorical approach to assess depression. The current study looks to identify grey matter volumes (GMV) that predict depressive symptomatology across a clinically concerning sample of adolescents.

Methods: Structural MRI data were collected from 338 clinically concerning adolescents (mean age = 15.30 SD=2.07; mean IQ = 101.01 SD=12.43; 132 F). Depression symptoms were indexed via the Mood …

The Correlational And Predictive Ability Of Pre-Season Risk Screenings On Hip And Groin Problems In Competitive Male Ice Hockey Players, William Suits

Dissertations

Background

Symptoms and disability due to conditions affecting the hip and groin are common in competitive male ice hockey players and can lead to long-term adverse health consequences. It is common practice for injury risk screenings at the beginning of the competitive season (preseason) to identify those with hip and groin symptoms and disability and guide primary and secondary prevention strategies. Commonly cited risk factors include total hip rotation range of motion (ROM), hip adductor strength, and the ratio of hip adductor to abductor strength. However, there is conflicting research regarding the utility of these preseason risk screenings, and the …

Evaluating The Need For Return-To-Learn Concussion Protocols In High School Student-Athletes: An Integrative Review, William David Midgette

Doctoral Dissertations and Projects

Over a million high school students are estimated to sustain at least one sports-related concussion annually. Unfortunately, over a third of these student-athletes suffer from post-concussion syndrome, which leads to the question of whether student-athletes are allowed proper time to heal after a concussion or if more can be done to optimize concussion recovery. Proper and optimal recovery post-concussion encompasses both physical and cognitive rest. While concussion management has traditionally focused on the physical aspects of recovery, emphasis has shifted to the cognitive impacts of concussions. There is literature to support that cognitive rest is vitally important, if not equally …

Understanding Athletes’ Experience When Transitioning To Life Beyond Sport, Mary L. Dell'arciprete, M Lauren Dell'arciprete

Department of Occupational Therapy Entry-Level Capstone Projects

Discontinuation may be by choice or may be due to an injury; however most collegiate athletes’ sports engagement ends due to graduation causing them to shift their role in an occupation that played a crucial role in their self-identity. Athletes of all levels are challenged in their transition beyond sport and in the adjustment to the various role changes that occur. A significant life event, such as the end of one’s athletic engagement, can cause a loss of identity, purpose, and mental health decline. Former athletes may experience occupational disruption, a temporary inability to adequately engage in meaningful tasks due …
