The Effects Of Vertically-Oriented Resistance Training On Golf Swing Performance Variables, Austin R. Driggers

Electronic Theses and Dissertations

The purpose of this study was to examine the effects of vertically-oriented resistance training on golf driving performance. Ten Division-I collegiate golfers completed 2 resistance training sessions per week for 10 weeks during the fall tournament season. Pre- and posttraining assessments of strength-power and golf performance were compared. To assess strength-power, jump height, peak force, and peak power (PP) were measured from static and countermovement (CMJ) vertical jumps; peak force and rate of force development from 0-250 ms were measured from an isometric mid-thigh pull. Golf performance was assessed in terms of ball launch speed (BS), spin rate, carry yardage …

Lower Body Strength And Power Characteristics Influencing Change Of Direction And Straight-Line Sprinting Performance In Division I Soccer Players: An Exploratory Study, Chieh-Ying Chiang

Electronic Theses and Dissertations

The purpose of this dissertation was to investigate the influence of lower body strength characteristics on change of direction (COD) performance in NCAA Division I soccer athletes. Specifically, this dissertation served to examine: 1) whether the lower body strength and power were related to COD performance, 2) whether stronger athletes had superior COD performance than weaker athletes, 3) whether the force production asymmetry and strength dominant (SD) associated with COD performance, and 4) weather sex differences existed in kinetic variables during the stand phase of cutting.

The major findings of this dissertation include: 1) strength and power characteristics were moderately …

A Review Of Recent Perspectives On Biomechanical Risk Factors Associated With Anterior Cruciate Ligament Injury, Gerwyn Hughes

Kinesiology (Formerly Exercise and Sport Science)

There is considerable evidence to support a number of biomechanical risk factors associatiated with non-contact anterior cruciate ligament (ACL) injury. This paper aimed to review these biomechanical risk factors and highlight future directions relating to them. Current perspectives investigating trunk position and relationships between strength, muscle activity and biomechanics during landing/cutting highlight the importance of increasing hamstring muscle force during dynamic movements through altering strength, muscle activity, muscle length and contraction velocity. In particular, increased trunk flexion during landing/cutting and greater hamstring strength are likely to increase hamstring muscle force during landing and cutting which have been associated with reduced …

Muscle Damage After A Tennis Match In Young Players, Rodrigo Vitasovic Gomes, Ricardo Santos, Ken Nosaka, Alexandre Moreira, Elen Miyabara, Marcelo Saldanha Aoki

Research outputs 2014 to 2021

The present study investigated changes in indirect markers of muscle damage following a simulated tennis match play using nationally ranked young (17.6 ± 1.4 years) male tennis players. Ten young athletes played a 3-hour simulated match play on outdoor red clay courts following the International Tennis Federation rules. Muscle soreness, plasma creatine kinase activity (CK), serum myoglobin concentration (Mb), one repetition maximum (1RM) squat strength, and squat jump (SJ) and counter movement jump (CMJ) heights were assessed before, immediately after, and 24 and 48 h after the simulated match play. All parameters were also evaluated in a non-exercised group (control …

Is There A Relationship Between Hip Structure, Hip Muscle Strength, And Lower Extremity Frontal Plane Kinematics During Treadmill Running?, Michael William Robinson Baggaley

Theses and Dissertations--Kinesiology and Health Promotion

INTRODUCTION: Excessive hip adduction (HADD) has been associated with a number of lower extremity overuse injuries, and it has been suggested that it may be the result of reduced strength of the hip abduction musculature. Hip structure has been postulated to influence both hip abduction (HABD) strength and HADD. The purpose of this study was to investigate the relationship between hip structure, HABD strength, and frontal plane kinematics during running. METHODS: Peak isometric HABD strength, lower extremity kinematics, femoral neck-shaft angle (NSA), and pelvis width-femur length (pw-fl) ratio were recorded for 25 female subjects. Pearson correlations (P < .05) were performed between variables. RESULTS: A fair relationship was observed between femoral NSA and HABD strength (r = …
