The Effects Of Oxidative Stress And Age On Human Spermatozoa, Taryn Mcandrew
The Effects Of Oxidative Stress And Age On Human Spermatozoa, Taryn Mcandrew
Theses : Honours
Male infertility is now recognised as a significant factor in couples having difficulty conceiving. The impact of maternal age has long been known as a limiting factor, however recent research indicates that advancing paternal age can also negatively impact on a couple's chances of conception. One of the major contributing causes of male infertility has now been linked to spermatozoa exposure to reactive oxygen species (ROS). Such exposure induces oxidative stress when coupled with reduced total antioxidant capacity (TAC). Measures of both ROS and TAC are used as tests of oxidative stress status (OSS) which are used together to give …
Is Dance Good For The Body Or Not? : An Examination Of Body Awareness And Injury Prevention For Specialised Tertiary Dance Students, Kylie Murray
Theses : Honours
The purpose of this research paper is to discover more about tertiary dance and the effects that dance has on the body. I will discuss the pressures that dance places on the body, looking specifically at the years during full time study as a tertiary student. I will address dance issues such as common injuries, the reasons these injuries occur, prevention strategies, the effect that dance has on the mind and training conditions generally. Research into tertiary dance education programs, dance injuries, injury prevention, and general dance patterns will be supported by survey responses to come to some conclusions about …
Modulation Of Corticomotor Excitability During Passive And Active Wrist Flexion And Extension, Lilian Min Yen Chye
Modulation Of Corticomotor Excitability During Passive And Active Wrist Flexion And Extension, Lilian Min Yen Chye
Theses : Honours
Various mechanisms may alter corticomotor excitability to agonist and antagonist muscles during passive and active limb movement depending on parameters of movement and their functional role. A better understanding of these relationships is important for understanding basic motor control mechanisms, and may be relevant to motor rehabilitation programs after brain injury. The purpose of the present study was to compare changes in corticomotor excitability to wrist flexor and extensor muscles during different phases of movement (flexion/extension), and at rest and during actively or passively-mediated length changes. Motor evoked potentials (MEP) of the flexor carpi radialis (FCR) and extensor carpi radialis …
The Relationship Between Session Rate Of Perceived Exertion Measures And The Volume Load Of Resistance Training, Mirza Abdul Latif
The Relationship Between Session Rate Of Perceived Exertion Measures And The Volume Load Of Resistance Training, Mirza Abdul Latif
Theses : Honours
The purpose of the study was to investigate the relationship between session rate of perceived exertion (RPE) measures and the volume load (VL) during resistance training (RT). Twelve male and eight female participants (24.3 ± 4.2 years) performed three RT sessions per week for a period of four weeks. The RT sessions during the week consisted of strength, hypertrophy and power protocols that included the same four resistance exercises (bench press, squat, shoulder press and bench row). The participants performed 3 sets of 3 repetitions per exercise at a load of 75-90% of their 1-RM with a rest period of …
