The Effects Of 17-Beta-Estradiol On The Stretch And Failure Load Of The Medial Collateral Ligament Of Ovariectomized Females, Orchiectomized Males, And Intact Males, Joseph Petrino

Life and Environmental Sciences Undergraduate Theses

Female athletics are increasing in popularity around the world, and with this increase in female participation in sports there has also been an increase in knee injuries. Studies have indicated that female athletes participating in soccer and basketball are two and four times, respectively, more likely to sustain a knee injury than their male counterparts. The monthly fluctuating hormone levels that occur during the reproductive years of a female have been targeted as one of the causative agents for this higher prevalence. Estrogen receptors have been identified in tissues of males including the medial collateral ligament (MCL) and the anterior ...

Coordination Of The Lower Extremity Muscles During Gait Transitions, Lorna Louise Ogden

LSU Master's Theses

Often the approach to investigating muscular coordination during transitions entailed conducting tests at speeds held constant. This study investigated muscular activity during continuously changing speeds in order to further detail and quantify neuromuscular changes during gait transitions. Twelve healthy adults, 18-41 years of age, were recruited as participants. Informed consent was obtained. Gait transitions were induced by the speed of the treadmill changing with constant acceleration. Reflective markers were placed on anatomical landmarks of the hip, knee,ankle, heel, and 5 th metatarsal joint. Bipolar surface electrodes were positioned on the subjects’skin over the muscular bellies of the gluteus ...


Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone Jan 2002

Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone

LSU Master's Theses

The reliability of wavelet analysis (DWT), of heart rate variability during rest and exercise was examined for this study. All twenty-three participants visited the lab on two separate occasions no less than four weeks apart. All twenty-three participants were subjected to the spontaneous breathing (SB1), and HG60 exercise condition. Of those twenty-three participants, nine performed the HG20 exercise condition as well. It was found that during the SB1 condition, the R-R intervals were fairly reliable between days. However, the reliability of all the HRV parameters (SDNN, spectral components and wavelet components) were quite poor. Interestingly, however, during HG20, the reliability ...

The Effect Of Exercise Ball Training On Balance In Older Adults, Stephanie Happ Jan 2002

The Effect Of Exercise Ball Training On Balance In Older Adults, Stephanie Happ

Masters Theses

Prevention of falls through balance training is of great interest to the aging population. Falls can cause debilitating injuries, such as fractures, and can also lead to the beginning of a series of health complications. These resulting complications can cause the older individual to become feeble, and susceptible to future recurring falls. There is no previous research on the effects of Swiss Ball exercises on the balance of older adults. The purpose of this study was to evaluate the efficacy of an exercise regimen involving the use of Swiss Balls to improve the balance of older adults.

Eleven apparently healthy ...


The Relationship Between Movement Confidence And Level Of Physical Activity In Older Adults, Alastair Stewart Jan 2002

The Relationship Between Movement Confidence And Level Of Physical Activity In Older Adults, Alastair Stewart

Theses : Honours

The movement confidence model proposed by Griffin and Keogh (1982) determined level of movement confidence by including sensations of enjoyment and fear of harm as well as perceived competence. Whilst this has been studied in children there is a paucity of research into older Australian adults. For the purposes of this study Australian older adults were defined as people over 50 years of age, permanently residing in Australia. Therefore, this study had four major purposes. The first purpose was to identify the relative contributions of (a) perceived competence (PC), (b) enjoyment (EN), and (c) fear of harm (FH) to movement ...


Changes In Muscle Function And Motorneuron Excitability Of The Triceps Surae Following A Bout Of Fatiguing Eccentric Exercise, Mikala Pougnault Jan 2002

Changes In Muscle Function And Motorneuron Excitability Of The Triceps Surae Following A Bout Of Fatiguing Eccentric Exercise, Mikala Pougnault

Theses : Honours

A reduction in capacity of the neuromuscular system associated with exercise can occur from a wide range of physiological and psychological factors. Many researchers have investigated neural activation during exercise, or the effects of muscle damage associated with eccentric exercise, but few have studied the prolonged effects of a bout of eccentric exercise on strength and motorneuron excitability. Eleven male and female subjects (aged 20-43 years) were tested to determine the effects of a fatiguing bout of eccentric exercise upon maximal isometric plantarflexion strength, motorneuron excitability, and neural activation of the soleus (SOL) and medial gastrocnemius (MG). The exercise consisted ...

Thirty-three older adults (ages 70-95 years) were assessed using the CS-PFP 10 test battery and performed quadriceps strength testing at 0, 90, 180º/sec using the Biodex dynamometer. Values for torque are reported as peak torque (PT) and relative peak torque (AdjPT) in Nm/kg body weight. The range of values for PT was (PT0: 20.2-144.3 Nm; PT90: 14-113.6 Nm ...


Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen Jan 2002

Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen

LSU Master's Theses

The autonomic nervous system (ANS) modulation of the heart is of clinical importance because of its relevance to risk of life threatening arrhythmic events. Decomposition of heart rate variability (HRV) has been used to quantify ANS control of the heart. The traditional method for frequency analysis has involved the use of fast Fourier transformation (FFT). However, heart rate data typically violate assumptions of the FFT. Therefore, the assessment of HRV may benefit from other, potentially more suitable, mathematical approaches. For example, the discrete wavelet transformation (DWT) appears to have promise with respect to its ability to discriminate between healthy and ...
