Effect Of Caffeine Supplementation On Vertical Jump Performance, Heart Rate Variability, And Electromyography, Collin T. Garner
Effect Of Caffeine Supplementation On Vertical Jump Performance, Heart Rate Variability, And Electromyography, Collin T. Garner
Masters Theses
Research into caffeine’s ability to improve anaerobic performance is inconclusive. Eleven anaerobically trained individuals (mean age: 23.45 ± 1.51 years) participated in this study. Assessments of resting heart rate variability (HRV), exercise heart rate variability, surface electromyography (sEMG), static vertical jump (SJ), and countermovement vertical jump (CMJ) were conducted before and after administration of placebo and caffeinated treatments. Three trials of each vertical jump technique were performed before and after treatment administration. A 60-minute absorption period was utilized for absorption of the treatment following its ingestion. All participants performed testing on two separate occasions, once under the placebo condition and …
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Masters Theses
Training the musculature of the core continues to be perceived as an essential component of conditioning and rehabilitation settings (11). A popular way to train the core is with the use of instability devices, such as Swiss ball or suspension trainer. However, there is limited research on the effects of these devices on core muscle activity. The purpose of this study was to examine core muscle activity during side bridge variations with and without instability devices (Floor, Swiss Ball, and TRX) through electromyography (EMG) of the rectus abdominis, external oblique, erector spinae, and latissimus dorsi. 39 participants performed three variations …
