Abstract:

Stroke is a leading cause of disability worldwide. The most commonly stated goal following stroke is to regain the ability to walk independently, resulting in a large amount of rehabilitation time focussed on gait retraining. Identification of key variables that relate to and affect gait function is important in order to understand the factors associated with impaired gait and to guide future intervention strategies. Reduced muscle strength has been proposed as a key contributor to physical limitations after stroke and is commonly assessed in clinical and research settings. The aim of this the

Abstract:

The purpose of this dissertation was to examine the existence of force production and strength symmetry while concentrating on its role with performance. Specifically, in this dissertation I sought to determine if differences in symmetry exist between male and female athletes as well as between athletes of different strength levels. Various symmetry assessments were used and the amount of carryover between tests was also evaluated. Furthermore, the relationship between asymmetry magnitude and various aspects of jump performance was also assessed. The results showed that female athletes were mo

Abstract:

Abstract Low back pain (LBP) is a significant health problem in all developed countries. The high prevalence of LBP in youth is a cause of concern because a link has been reported between LBP in adolescence and chronic LBP (CLBP) in adulthood. In order to prevent CLBP in adulthood potential protective factors in youth should be identified. The association between trunk muscle strength and LBP has been widely studied but the results are conflicting. The current knowledge on the role of postural balance in relation to LPB is even more controversial. The aims of the thesis were to evaluate 1) the

Explosive strength, a function of rate of force development (RFD), is a primary determinant for the amount of peak force that can be produced in critical sport performance time periods ( e.g. foot contact time). Evidence indicates that maximum strength and RFD are correlated. However, the characteristics of this relationship are not well established among athletes. This study examined the relationship of peak isometric force (IPF) and RFD from a mid-thigh pull, among male and female track and field athletes.

Resistance training is a highly utilised form of exercise that is used to develop strength, power, speed and muscular endurance. Although it is associated with many positive benefits it also has some potentially unfavourable effects. These are manifested in the form of altered muscle function through the effects of muscle fatigue and exercise induced muscle damage. Various aspects muscle fatigue and damage have been well studied, however research into the effects of these on tests of strength, power, acceleration and agility is sparse. Therefore the aim of this study was to investigate the eff

Abstract:

The purpose of this dissertation was to determine if a periodized strength and conditioning program resulted in long-term adaptations in NCAA Division I women’s volleyball athletes, and if these changes related to the team’s competitive performance. Specifically, this dissertation serves to: 1.) describe the changes in body composition and performance variables of 2 female volleyball athletes over a 4-year collegiate career, 2.) determine the degree and magnitude of change in performance variables after about 1, 2, and 3 years of periodized resistance training, and 3.) infer if volleyball perf

Abstract:

Aim: The purpose of this study was: 1) to investigate the alterations and relationships among training variables, performance variables, and physiological variables and 2) investigate the effects of strength training on potentiation complexes. Methods: The study enrolled nine D-1 collegiate throwers and four control subjects. The throwers participated in an 11-week resistance training and throws program. Resistance training volume load and throwing volume were recorded for 11 weeks. Measurements of maximal strength (isometric mid-thigh pulls) and dynamic mid-thigh pulls (DMTP) across a spectru

Abstract:

The purpose of this dissertation was to evaluate the stability of strength asymmetry over a long-term period (1 year) and investigate the relationship of strength asymmetry to field test performance asymmetry in NCAA division-1 athletes. Isometric mid-thigh pull (IMTP) peak force asymmetry, ground contact time and finish time asymmetries on 10m sprint and 505 agility test performances were also observed. The impact of strength was also investigated in these studies to determine its effect on the magnitude of asymmetry. In the second study, peak force asymmetry over a one-year period was observ

Abstract:

Publication 1: The Isometric Mid-Thigh Pull: A Review and Methodology – Part 1 Isometric tests are commonly used to monitor physical qualities that underpin athletic performance. As single-joint laboratory-based tests display poor relationships to the multi-joint movements found in sport, multi-joint isometric tests like the isometric midthigh pull (IMTP) are commonly used instead. Force-time characteristics in these multijoint tests typically display stronger relationships to dynamic performance, particularly in the case of the isometric mid-thigh pull. As such this review focuses on the rela

Carry-over of force production symmetry in athletes of differing strength levels. J Strength Cond Res 29(11): 3188–3196, 2015—This study sought to determine the level of association between bilateral force production symmetry assessment methods (standing weight distribution [WtD], unloaded and lightly loaded jumps, and isometric strength) and to determine whether the amount of symmetry carry-over between these tasks differs for strong and weak athletes. Subjects for this study included male (n = 31) and female (n = 32) athletes from National Collegiate Athletic Association Division I sports. A

Introduction: Maximum running acceleration essential components in many sports. The identification of specific training protocols to maximize sprint speed would be useful knowledge for soccer coaches and players. Purpose: The purpose of this study was to determine the effect of a high-speed treadmill with the use of a body-weight support system in a 6-week sport acceleration program on: 40-yard sprint time, maximal isometric knee flexor and extensor strength. Methods: 32 female soccer players (age 16 ± 1.19 yrs) participated in two treatment groups and one control group. Both treatment groups

Abstract:

The purpose of this study was to determine the reliability of two new alternative portable methods for measuring maximal isometric force measures while performing the standard mid-thigh pull. One method, the bar grip method, required the use of the trunk and upper extremity muscles, while the second method, the pelvic belt method, did not. Both methods demonstrated good test-retest reliability via randomized repeated measures over 24-36 hours. Interestingly, the pelvic belt method generally demonstrated average maximal forces up to 65% higher than the bar method. There was a good relationship
