Role Of Brain Derived Neurotrophic Factor (Bdnf) In Stimulating Strength Improvements Induced By Short-Term Resistance Training, David Church
Electronic Theses and Dissertations
Strength adaptations from short-term resistance training are thought to be related primarily to neurological adaptations. Considering brain-derived neurotrophic factor (BDNF) role in the nervous system, it is possible that BDNF has a role in these adaptations. Fourteen untrained males were randomized into either a resistance training (RT; n =8) or control (CON; n=6) group. Motor unit (MU) recruitment at 50% and 80% of each participant's maximal voluntary isometric contraction (MVIC), muscle cross sectional area (CSA) and thickness (MT), as well as one-repetition maximum (1RM) of the squat (SQT), leg press (LP), and leg extension (LE) were performed before (PRE) and …
Examining Work-To-Rest Ratios To Optimize Upper Body Sprint Interval Training, Michael La Monica
Examining Work-To-Rest Ratios To Optimize Upper Body Sprint Interval Training, Michael La Monica
Electronic Theses and Dissertations
The primary purpose of this study was to compare the metabolic influence of varying work-to-rest ratios during upper body sprint interval training (SIT). Forty-two recreationally trained men were randomized into one of three training groups [10s work bouts with two minutes of rest (10:2, n = 11) or four minutes of rest (10:4, n = 11), or 30s work bouts with four minutes of rest (30:4, n = 10)] or a control group (CON, n = 10). Participants underwent six training sessions over two weeks with four to six 'all-out' sprints. During pre- and post-intervention visits, participants underwent a graded …
Mechanical And Physical Characteristics Of Knee Flexors And Extensors Following Different Warm Up Protocols In Collegiate Male Soccer Athletes, Michael Redd
Electronic Theses and Dissertations
PURPOSE: To compare potential differences in mechanical and physical characteristics of knee flexors and extensors in collegiate male soccer players following different warm up protocols. METHODS: Sixteen collegiate male soccer players (20.33 ± 1.33 years, 176.97 ± 6.72 cm, and 78.43 ± 7.42 kg) participated in this study. A small sided games warm up (SSG), a dynamic warm up (DYN), and a plyometric warm up (PLY) were completed using a randomized crossover design. Tensiomyography (TMG) was used to assess contraction time (Tc), delay time (Td) and maximal displacement (Dm) of the rectus femoris (RF) and biceps femoris (BF) of both …
