The Influence Of Strength In Load-Velocity Relationships In The Back Squat, Thaddeus Light
The Influence Of Strength In Load-Velocity Relationships In The Back Squat, Thaddeus Light
Electronic Theses and Dissertations
Load-velocity relationships may vary between people of different strength levels and across different loads. The purpose of this dissertation was to investigate how external loads influence the velocity characteristics of the back squat exercise, and the influence of strength on these variables. Healthy male students with a history of resistance training completed repetitions at specified intensities of their estimated one-repetition maximum (1RM) until they reached 1RM. Back squat 3D motion analysis was captured using four Vicon T010 cameras (Vicon Motion Systems Ltd.; Oxford, UK) and Vicon Nexus 1.8.5 software. Data were transported into R custom coding statistical analysis software (version …
Changes In Psychological, Morphological, And Performance Characteristics In Preparation For A National Weightlifting Competition, Donald Marsh
Electronic Theses and Dissertations
The primary aim of this study was to examine the time course of change in muscle morphology and vertical jump performance in weightlifters preparing for a national competition. The secondary aim of this study is to examine how perceived recovery and stress state corresponds with alterations in training load leading up to competition. Eleven Olympic Training Site weightlifters completed a 4-week peaking phase for a national competition. Body mass, stress and recovery psychometric measures, and unloaded/loaded (20kg) squat jump height (SJH) were measured weekly and at the competition site. Vastus lateralis cross-sectional area (CSA), muscle thickness (MT) and pennation angle …
Phase Specific Changes In Rate Of Force Development And Muscle Morphology Throughout A Block Periodized Training Cycle In Weightlifters, Dylan Guidetti Suarez
Phase Specific Changes In Rate Of Force Development And Muscle Morphology Throughout A Block Periodized Training Cycle In Weightlifters, Dylan Guidetti Suarez
Electronic Theses and Dissertations
The purpose of this study was to investigate the kinetic and morphological adaptations that occur during distinct phases of a block periodized training cycle in weightlifters. Monitoring data from nine experienced collegiate weightlifters was examined retrospectively. Isometric mid-thigh pull and ultrasonography results from pre and post three specific training phases within a macrocycle leading up to a competition were compared. Changes in isometric rate of force development and vastus lateralis cross-sectional area reflected the expected adaptations of each training phase.
