International Journal of Exercise Science

International Journal of Exercise Science 7(3) : 179-185, 2014. Tabata (TAB) training, consisting of eight cycles of 20 seconds of maximal exercise followed by 10 seconds of rest, is time-efficient, with aerobic and anaerobic benefit. This study investigated the cardiovascular and metabolic demands of a TAB versus traditional (TRAD) resistance protocol with the kettlebell swing. Fourteen young (18-25y), non-obese (BMI 25.7±0.8 kg/m²) participants reported on three occasions. All testing incorporated measurements of HR, oxygen consumption, and blood lactate accumulation. Each participant completed Tabata kettlebell swings (male- 8kg, female- 4.5kg; 8 intervals; 20s maximal repetitions, 10s rest). On a …

Is There An Optimal Whole-Body Vibration Exposure ‘Dosage’ For Performance Improvement?, R Hugh Morton, Darryl J. Cochrane

International Journal of Exercise Science

International Journal of Exercise Science 7(3) : 169-178, 2014. Whole-body vibration exposure has been shown to improve performance in vertical jumping and knee extensions. Some studies have addressed the question of dose optimality, but are inconclusive and inappropriately designed. Our purpose was to more thoroughly seek an optimum combination of duration, amplitude and frequency of exposure to side-alternating whole-body vibration. We used experimental designs constructed for response surface fitting and optimisation, using both blocked and unblocked second order central composite designs with 12 participants. Immediately after each exposure a discomfort index was recorded, then peak and average torque, peak and …

Quantitative Ultrasound: Measurement Considerations For The Assessment Of Muscular Dystrophy And Sarcopenia, Michael O. Harris-Love, Reza Monfaredi, Catheeja Ismail, Marc R. Blackman, Kevin Cleary

Exercise and Nutrition Sciences Faculty Publications

Diagnostic musculoskeletal ultrasound has potential clinical utility in characterizing pathological muscle tissue. Sonography has been long proposed as method of assessing muscle damage due to neuromuscular diseases such as muscular dystrophy, and more recently, changes in body and tissue composition associated with muscle wasting disorders such as sarcopenia. The use of quantitative ultrasound as an adjunct diagnostic procedure has different technical challenges than the traditional use of ultrasound in clinical medicine. Operator-dependent technique and variation are critical considerations when obtaining measures of echointensity (i.e., tissue composition estimates) and tissue dimensions (i.e., muscle thickness) – key elements of the ultrasound assessment …

The Effects Of Opedix < Sup > Tm < / Sup > Knee Support System, Philip Mathew

Theses and Dissertations

INTRODUCTION: Knee supports are often employed to decrease adductor angle and/or adductor moment and thus medial knee joint loading in persons with medial knee osteoarthritis. It is compelling that these gait alterations would also be considered beneficial in healthy individuals from a prophylactic application. While the Opedix product was designed specifically as a knee support system, in the present study lower extremity kinematic chain with emphasis on hip and knee were investigated.

PURPOSE: The purpose of this study was to test Opedix garments and describe the changes in sagittal (X), frontal (Y), and transverse (Z) planes for both kinematic and …

The Effect Of Music Cadence On Step Frequency In The Recreational Runner, Micaela A. Galosky

USF Tampa Graduate Theses and Dissertations

Music appears to have advantageous effects during exercise as it has been shown to increase motivation, decrease ratings of perceived exertion (RPE), and improve exercise performance. The improvement of running performance in particular, is the main effect recreational runners want to focus on as many want to improve their time in road races. Running velocity, indicated by a faster time to completion is thought to improve with an increase in step frequency, step length, or a combination of these variables. Currently, there is limited research that observes methods to help increase step frequency or step length. The manipulation of music …

The Effects Of Cognitively Engaging Physical Activity On The Executive Function Of Sixth Graders, Alyssa Michele Humphreys

Theses and Dissertations

This purpose of this study was to examine the effects of cognitively engaging exercise, aerobic exercise, and resting conditions on the executive function of 6th graders. Four conditions were tested: cognitively engaging exercise, repetitive aerobic exercise, cognitively engaging rest, and rest. Executive function was measured by pre and post Stroop tests, which is a test of reaction time and inhibition. Results showed no significant differences between conditions in the choice reaction time test, however the cognitively engaging exercise was significantly different from all other conditions on the Stroop test.

Analysis And Application Of Passive Gait Rehabilitation Methods, Ismet Handzic

USF Tampa Graduate Theses and Dissertations

Human gait is elegant and efficient in propelling the body forward. While a healthy human gait is symmetric, any deviation from symmetry can cause inefficiencies to the entire body. Such asymmetries may present themselves in hemiplegic patients, prosthetic users, lower limb injuries, limb height and weight discrepancies, or abnormal overground foot rolling. In this dissertation, practical passive methods to alleviate such asymmetric walking dynamics are presented. The novel concepts presented in this manuscript can all be related and applied to passive gait rehabilitation, that is, the rehabilitation of a person's gait through methods that do not require external power. One …

Design, Development And Testing Of A Balance Board With Variable Torsional Stiffness And Time Delay, Denise Renee Cruise

Open Access Theses

The ability to balance and maintain upright posture can decline for a variety of reasons, such as aging and neuromuscular impairment. As the ability to balance declines, the risk of falling increases. Falls are a major cause of injury, and often lead to a dramatic decline in quality of life. Currently, to alleviate balance deficiencies, people participate in balance training, which most commonly refers to standing on an unstable balance board; the most common boards used are either passive wobble boards, or more advanced commercial systems such as the Biodex System SD ® or the Neurocom SMART Balance Master® . …

Lateral Line Analogue Aids Vision In Successful Predator Evasion For The Brief Squid, Lolliguncula Brevis, Carly A. York, Ian K. Bartol

Biological Sciences Faculty Publications

Cephalopods have visual and mechanoreception systems that may be employed to sense and respond to an approaching predator. While vision presumably plays the dominant role, the importance of the lateral line analogue for predator evasion has not been examined in cephalopods. To test the respective roles of vision and the lateral line analogue, brief squid, Lolliguncula brevis, were observed in the presence of summer flounder, Paralichthys dentatus, under light and dark conditions with their lateral line analogue intact and ablated. Hair cell ablation was achieved through a pharmacological technique used for the first time on a cephalopod. The …
