The Effects Of Ankle Taping On Measures Of Ground Reaction Forces And Jump Height During A Sport-Specific Vertical Jump In Youth Basketball Players, Michelle Pratola, Paolo Sanzo

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 898-911, 2023. The purpose of this study was to investigate the effects of ankle taping using zinc oxide tape versus no tape to measure ground reaction forces (GRF) and vertical jump height during a sport-specific vertical jump test in youth basketball players. Participants were recruited through purposive sampling and completed a basketball specific vertical jump test with and without zinc oxide tape. Mean sway velocity, 95% ellipse area, and path length were measured using the AMTI© force platform and vertical jump height using a Vertec© device. A paired t-test with a significance level of …

The Biomechanical Effects Of Percussive Therapy Treatment On Jump Performance, Fany Alvarado, Kevin Valenzuela, Amanda Finn, Elizabeth L. Avila, Jill Crussemeyer, Mikiko Nakajima

International Journal of Exercise Science

International Journal of Exercise Science 15(1): 994-1006, 2022. Percussive therapy treatment is one form of myofascial release that has gained popularity amongst the sport community. It has been suggested that percussive therapy treatment may improve range of motion and improve athletic performance, but these claims are largely anecdotal. Currently, the effects of percussive therapy treatment on performance of athletic tasks is relatively unknown. Therefore, the purpose of this research was to assess the effects of percussive therapy treatment on jump performance and passive range of motion. Twenty-six recreationally active college individuals performed countermovement jump and drop jump activities on two …

Physiological, Musculoskeletal & Anthropometric Characteristics & Performance Between Competitive & Recreational Surfers: A Scoping Review, Harrison Stone, Lucy Douglas, James Furness, Kevin Kemp-Smith, Mike Climstein, Sean Newcomer

International Journal of Exercise Science

International Journal of Exercise Science 14(6): 1277-1293, 2021. Surfing is the ability to ride a surfboard along the unbroken section, wall or face of a wave, as it moves closer towards the shore. The purpose of this review is to provide an overview of the physiological, musculoskeletal and anthropometric characteristics that can differentiate between paddling and wave riding performance in competitive and recreational surfing populations. The eligibility criteria for this scoping review included articles that distinguished between multiple surfing ability groups, identified physiological, musculoskeletal or anthropometric characteristics, were peer reviewed, and directly related to the sport of surfing. The databases …

The Acute Effects Of Antagonist Stretching On Agonist Movement Economy, Justin Shahtout, Shawn Henry, Dylan Ito, Kyle Savellano

International Journal of Exercise Science

International Journal of Exercise Science 13(4): 1295-1304, 2020. Current research on the effects of stretching on movement performance varies. However, these studies focused on stretching agonist and antagonist muscle responsible for movement production. Few studies investigated the influence of antagonist stretching on exercise performance. The purpose of this study is to examine the acute effects of antagonist stretching on agonist movement economy. 14 participants (5 male, 9 females; 168.32 ± 7.63 cm stature; 65.00 ± 7.28 kg mass) completed baseline active ROM (AROM) and passive ROM (PROM) measurements. The experimental design required participants to complete two 5 min trials of …

A Single Bout Of Foam Rolling Increases Flexibility Of The Hip Adductor Muscles Without Compromising Strength, Gavin Connolly, Roger L. Hammer, Joseph A. Powell, Paul L. O'Connor

International Journal of Exercise Science

International Journal of Exercise Science 13(7): 938-949, 2020. Foam rolling (FR) is a method of self-myofascial release (SMR) implemented to reduce tension in underlying soft tissue, leading to increased range of motion (ROM). The hip adductor muscles of the groin are commonly less flexible and often a site for soft tissue injuries. Limited research has been done to determine the most effective flexibility exercises to increase ROM in the groin muscles prior to exercise without comprising strength. The purpose was to determine the effect of an acute bout of FR on passive groin flexibility and strength. Randomized crossover study with …

Comparison Of Two Static Stretching Procedures On Hip Adductor Flexibility And Strength, Brandon Fjerstad, Roger L. Hammer Dr., Adam Hammer, Gavin Connolly, Karen Lomond, Paul O'Connor

International Journal of Exercise Science

International Journal of Exercise Science 11(6): 1074-1085, 2018. It has been shown that acute static stretching (SS) may increase flexibility, improve performance and reduce the risk of muscle strains, but may also result in decreased maximal force output. Literature review revealed little research had specifically been done on the most effective ways to stretch the hip adductor muscles. The purpose was to determine the effects that an acute bout of SS (active vs passive) has on hip adductor flexibility and maintenance of strength. Randomized cross-over study using a 3 X 2 (Condition X Time) repeated measures ANOVA statistical design. Forty …

Clinical Methods To Quantify Trunk Mobility In An Elite Male Surfing Population, James Furness, Michael Climstein, Jeremy Sheppard, Allan Abbott, Wayne Hing

James Furness

Background

Thoracic mobility in the sagittal and horizontal planes are key requirements in the sport of surfing; however to date the normal values of these movements have not yet been quantified in a surfing population.

Objectives

To develop a reliable method to quantify thoracic mobility in the sagittal plane; to assess the reliability of an existing thoracic rotation method, and quantify thoracic mobility in an elite male surfing population.

Design

Clinical Measurement, reliability and comparative study.

Methods

A total of 30 subjects were used to determine the reliability component. 15 elite surfers were used as part of a comparative analysis …

The Relationship Among Ankle Function, Functional Capacity, And Body Composition To Balance In Geriatric Populations, Joseph Robert Chaney

Graduate Theses and Dissertations

The primary purpose of this research study was to identify significant relationships among measures of ankle strength, ankle range of motion, body composition, and functional capacity to balance ability in geriatric populations which may potentially assist in identifying older individuals with increased risk of falling. A battery of five test (ankle strength assessments, ankle range of motion , DXA, functional fitness, and balance) were administered to 20 participants (6 males, 14 females, mean age 69.78 ± 3.98) that had indicated to be at least 65 years of age or older and no history of falls within the previous 12 months. …

Effect Of Single Set Dynamic And Static Stretching Exercise On Jump Height In College Age Recreational Athletes, Jeffrey C. Murphy Dr., Elizabeth F. Nagle, Robert J. Robertson Dr., Jean L. Mccrory Dr.

International Journal of Exercise Science

This study examined the effects of single set dynamic and static stretching on vertical jump height and hip and knee range of motion in a sample of college age recreational males. Forty-two males (aged 18-24) healthy, physically active volunteers participated as subjects in this investigation and were randomly assigned to one of three groups (1 set of 20 seconds dynamic stretch, 1 set of 20 second static stretch, or control). The knee and hip range of motion, sit and reach, and jump height were measured before and after the treatment condition. The same measures were performed on the control group …

The Effects Of Two Types Of Fatigue On An Unanticipated Side-Step Cutting Task As Measured By Kinematic And Kinetic Variables, Shawn E. Lucci

Human Movement Studies & Special Education Theses & Dissertations

Fatigue has been shown to alter the neuromechanics of lower extremity. To date, no study has examined the effects of two types of fatigue on kinetics and kinematics. To determine neuromechanical differences between two fatigue protocols [Slow Linear Oxidative Fatigue Protocol (SLO-FP) and Functional Agility Short-Term Fatigue Protocol (FAST-FP)] when performing an unanticipated sidestep cutting task. Fifteen female collegiate soccer players (age=19.2±0.8 years; height=l.67±0.05m; mass=61.7±8.lkg) participated in this study. Participants were free of lower extremity injury at time of participation, and performed five successful trials of a sidestep cutting (SS) task pre and post fatigue protocols. For the SLO-FP, a …
