A Comparison Of Three Cam Profiles As Measured By Emg And Angular Displacement, Elizabeth Grace Ann Hood

Human Movement Studies & Special Education Theses & Dissertations

The purpose of this study was to determine if variations in cam profiles cause differences in muscle contraction as measured by surface EMG, knee joint angular displacement, and torque. There were seven hypotheses tested. The ten subjects were adult male volunteers (18-24 years) who participated in a counterbalanced treatment design study testing three variously shaped cams over five lifting tests. The results indicated that for the EMG data, the cam and lifts effect had significant Wilk's values. For the cam effect the consistent cam had the highest millivolt value. For the lift effect, the pre 1 rep max had the …

The Historical Transformation Of Swimming Into A Modern Leisure Activity, Stephanie J. Haas

Student Work

The purpose of this study is to trace the transformation of swimming from its earliest appearance in the literature to its contemporary form as a modern leisure activity. The processes of rationalization, legitimation and democratization are examined in pre-industrial, industrial, and post-industrial societies.

An investigation of the available literature disclosed negative attitudes toward swimming during the Middle Ages which caused a decrease in expressive uses of swimming. After this period, swimming's acceptance as a legitimate leisure activity continued to increase through the industrial and post-industrial eras. The democratization of swimming seemed limited to societies on the coasts of large bodies …

Optimization Of The Seating Position In A Human-Powered Vehicle, Y. Lei, Mohamed Trabia, D. Too

Mechanical Engineering Faculty Research

Until recently, most of the human-powered vehicles (HPV) were designed focusing solely on its aerodynamics characteristic. In many of these HPV designs, the rider seating position was arbitrarily chosen without consideration of its effect on the rider's comfort and cycling effectiveness. Also, there is no guarantee that the seating position is related to maximum power output. Too (1991) used an experimental approach to determine that the rider will produce the maximum anaerobic power when the seat tube angle of a bicycle is at 75° whereas Hull and Gonzalez (1990) used an engineering approach to optimize the cycling biomechanics. However several …

A Historic Accomplishment: The First Blind Person To Hike The Appalachian Trail, Joseph H. Huber

Bridgewater Review

On November 21, 1990 Bill Irwin, 50 arrived at the base of Mount Katahdin in Main’s Baxter State Park, thus completing a walk of the footpath known as the Appalachian Trail. Irwin’s goal of hiking the entire Trail began on March 8, 1990. His excursion through extensive wilderness in 14 states include 8 national forests and about 0 state parks and game lands.

Unlike most through-hikers – those attempting to walk the entire 2,144 miles of the trail starting from Springer Mountain in northern Georgia to Mount Katahdin in one hiking season – Irwin’s accomplishment attracted a great deal of …

The Effect Of Heart Rate And Rating Of Perceived Exertion While Exercising On The Stairmaster 4000pt With And Without Upper Body Support, Nicole Lamkin

Masters Theses

The purpose of this study was to determine if any differences exists between heart rate and rating of perceive exertion during exercise on the StairMaster 4000pt with and without upper body support. Thirteen female intercollegic athletes were examined during a 1.5 mile run and eight minutes of supported and eight minutes of non-supported StairMaster exercise. The subjects worked at a slow step rate for the first two minutes (4.9 METs) and the last six minutes each subject worked at 70% of their submaximal level achieved on the 1.5 mile run. Variables measured included HR and RPE. A one factor ANOVA …

Cardiovascular Responses Of Trained Cyclists To Different Pedaling Rates At A Constant Power Output On A Cycle Ergometer, David C. Immke

Masters Theses

Previous research has not resolved the issue as to which pedaling rate is the most efficient in terms of oxygen uptake (VO₂) for competitive cyclists. The purpose of this study was to determine the most efficient pedaling rate (30, 60, or 90 rpm) at steady state submaximal cycling (720 kpm/min) for trained cyclists. Eight healthy subjects (all male) were examined during steady state exercise for each of the three trials for which work rate was kept constant with varying pedal rate and resistance. Variables included oxygen uptake, cardiac output, heart rate, stroke volume, arterio-venous O₂ difference, respiratory …

Effects Of Music And Sensory Deprivation On Ratings Of Perceived Exertion And Exercise Affect, James Chinery

Masters Theses

Music as an ergogenic aid is a novel concept, and one that has been sporadically researched. The purpose of this thesis was to study the effects of music and sensory deprivation on ratings of perceived exertion during exercise.

Eleven active males (i.e. they exercised at least 3 times a week), were tested in three different conditions (music, sensory deprivation, control). They exercised in each condition, at workloads corresponding to 50, 70 and 90% of their maximal oxygen consumption. The sessions and workloads within each session were randomized.

No significant differences were found for heart rate between conditions. Significantly lower perceived …

The Effect Of Age On Recovery Of Heart Rate After Exercise, Shari A. Delisle

Masters Theses

The purpose of this study was to determine if heart rate recovery, following exercise, of active women aged between 50-63 years was significantly slower than the recovery of active women aged 23-24 years when both groups exercised at the same relative perceived intensity. Ten female subjects, five young and five older, were tested during a five minute bout of treadmill exercise while working at a rating of perceived exertion(RPE) of 14. Heart rate was measured prior to and during testing and into recovery using the Vantage Performance Monitor. The time, measured in seconds, it took for each subject to drop …

An Electromyographic Study Of Forward Vs Retrograde Stair Climbing On The Stairmaster 4000 Pt Machine, W. Lynette Rasmussen Thornburgh

Masters Theses

The purpose of this study was to investigate, through electromyography, whether forward or retrograde stair climbing on the StairMaster 4000 PT machine demonstrates a greater muscle contraction duration, differences in intensity of muscle contractions, or variation in initiation of muscle contractions. The muscles examined were the Rectus Femoris, Vastus Medialis, and Biceps Femoris. A gender difference was also evaluated.

Twenty-one subjects apparently healthy volunteered for this study. There were two groups of ten male subjects and eleven female subjects. Subjects were assigned to subgroups according to gender. The subgroups determined which position the subject was tested in first.

The descriptive …

A Survey Of Opinions And Knowledge Of Parents Of High School Athletes About Athletic Training, Brooke Lynn Bixby

Dissertations and Theses @ UNI

The purpose of this study was to describe the opinions and beliefs of parents of high school athletes in Cedar Falls, IA about the need for a certified athletic trainer to be employed by the high school. Subproblems in this study were to determine: (a) the parents' opinions concerning the importance of athletic trainers, (b) their knowledge and awareness of an athletic trainer's duties and responsibilities, and (c) their willingness to participate in a funding program for a certified ~thletic trainer to be employed at the high ichool. An 18-item questionnaire was mailed to 100 parents of athletes attending Cedar …
