The Acute Effects Of Ballistic And Non-Ballistic Concentric-Only Half-Squats On Squat Jump Performance, Timothy J. Suchomel 2015 East Tennessee State University

The Acute Effects Of Ballistic And Non-Ballistic Concentric-Only Half-Squats On Squat Jump Performance, Timothy J. Suchomel

Electronic Theses and Dissertations

The purposes of this dissertation were to examine bilateral asymmetry as a factor of postactivation potentiation, examine and compare the acute effects of ballistic and non-ballistic concentric-only half-squats on squat jump performance, and compare the potentiation and temporal profiles of strong and weak subjects following potentiation protocols that included ballistic and non-ballistic concentric-only half-squats. The following are major findings of the dissertation. Squat jump performance may be acutely enhanced following ballistic concentriconly half-squats; however the changes in performance do not appear to be related to bilateral symmetry. Ballistic concentric-only half-squats acutely improve various squat jump performance variables at various time ...


An Investigation Of The Relationship Between A Static Jump Protocol And Squat Strength: A Potential Protocol For Collegiate Strength And Explosive Athlete Monitoring, Cody Haun 2015 East Tennessee State University

An Investigation Of The Relationship Between A Static Jump Protocol And Squat Strength: A Potential Protocol For Collegiate Strength And Explosive Athlete Monitoring, Cody Haun

Electronic Theses and Dissertations

The purpose of this study was to examine the relationship between estimated absolute and relative squat strength and a static jump protocol with potential to provide desirable training adaptation data to practitioners in the field of collegiate strength and conditioning. Forty-one young (20.80 ± 2.44 years), healthy volunteers reported estimated back squat 1RM’s based on the most recent training block and completed a static jump protocol. Males (n=19, est. 1RM 141.29 ± 32.02kg) and female (n=22, est. 1RM 71.56 ± 19.64kg) jump data revealed large to very large correlations between squat strength, mean jump ...


Relationship Between Concentric Velocity At Varying Intensity In The Back Squat Using Wireless Inertia Sensor, Kevin M. Carroll 2015 East Tennessee State University

Relationship Between Concentric Velocity At Varying Intensity In The Back Squat Using Wireless Inertia Sensor, Kevin M. Carroll

Electronic Theses and Dissertations

The purpose of this study was to determine the relationship between the Minimal Velocity Threshold (MVT) of 1RM and repetitions until failure testing conditions using the back squat exercise. Fourteen injury-free males with experience in the back squat volunteered to perform a 1RM and a submaximal (70% 1RM) repetitions until failure test, each during different testing sessions. Mean Concentric Velocity (MCV) was collected using a wireless inertia-measuring device. The last successful repetition in either condition was considered the MVT. A very small relationship between 1RM and repetitions until failure MVT was found (r=-0.135). There were no significant differences ...


Comparison Of External Kinetic And Kinematic Variables Between High Barbell Back Squats And Low Barbell Back Squats Across A Range Of Loads, Jacob Goodin 2015 East Tennessee State University

Comparison Of External Kinetic And Kinematic Variables Between High Barbell Back Squats And Low Barbell Back Squats Across A Range Of Loads, Jacob Goodin

Electronic Theses and Dissertations

This study compared peak force, peak power, peak velocity, impulse, work, and vertical displacement between the high bar back squat (HBBS) and low bar back squat (LBBS). Six trained males performed each using 20, 30, 40, 50, 60, 70, 80, and 90% of their recent training 1 repetition maximum. Dual force plates recorded force-time curve characteristics of ground reaction forces and four potentiometers tracked vertical and horizontal barbell displacement. Repeated–measures analysis of variance revealed a significant main effect for load (p<0.01) across all variables, but no significant effects for condition or interaction. The HBBS generated higher peak force in loads 20%–80%, higher peak power in loads 20%–60% and 80%–90%, higher peak velocity at every load, and greater vertical displacement at every load. The LBBS generated a larger impulse at loads 30%-90% and the HBBS generated more work at loads 20%, 40%, and 60%–90%.


Effects Of A Novel High Intensity Interval Training Protocol Versus Continuous Training In National And International Class Collegiate Rowers On Indices Of Aerobic And Anaerobic Power, Sylvie D. Richer 2015 The University of Western Ontario

Effects Of A Novel High Intensity Interval Training Protocol Versus Continuous Training In National And International Class Collegiate Rowers On Indices Of Aerobic And Anaerobic Power, Sylvie D. Richer

University of Western Ontario - Electronic Thesis and Dissertation Repository

The purpose of this investigation was to compare 6 high intensity interval training (HIIT) sessions with predominately continuous training (CONT) over 11 days on elite rowers. Two groups (n=8) completed an incremental ramp test to determine Peak Aerobic Power (PAP), and a Critical Power test (CP). HIIT sessions consisted of 10 bouts of 10 s work (140% of PAP) with 5 s recovery, followed by 8 min of active recovery; repeated 6 times. 60 s power decreased in CONT (510±167–489±171W; p=0.02). CP increased in both groups (HIIT: 336±59-360±59W; CONT: 290±73-316±74W ...


Acute Effects Of Self-Myofascial Release And Static Stretching On Shoulder Range Of Motion And Performance In Overhead Athletes With Glenohumeral Internal Rotation Deficit, Ryan R. Fairall 2015 Seton Hall University

Acute Effects Of Self-Myofascial Release And Static Stretching On Shoulder Range Of Motion And Performance In Overhead Athletes With Glenohumeral Internal Rotation Deficit, Ryan R. Fairall

Seton Hall University Dissertations and Theses (ETDs)

Purpose: The purpose of this study was to examine the acute effects of a) self-myofascial release (SMR), b) static stretching (SS), and c) the combination of self-myofascial release and static stretching (SMR+SS) on glenohumeral internal rotation range of motion and markers of shoulder performance (i.e. glenohumeral external rotation isometric strength, motor unit recruitment, and throwing velocity) in male softball players with glenohumeral internal rotation deficit (GIRD).

Methods: The sample consisted of 12 male amateur softball players (age: 36.92 ±11.17 years; height: 177.42 ±6.30cm; mass: 87.58 ±18.39kg) who exhibited ≥20° less internal rotation ...
