Formulation To Predict Lower Limb Muscle Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, A. Barjau, Benjamin J. Fregly, Josep M. Font-Llagunes

Mechanical and Aerospace Engineering Faculty Publications

The human body has more muscles than Degrees of Freedom (DoF), and that leads to indeterminacy in the muscle force calculation. This study proposes the formulation of an optimization problem to estimate the lower-limb muscle forces during a gait cycle of a patient wearing an instrumented knee prosthesis. The originality of that formulation consists of simulating muscle excitations in a physiological way while muscle parameters are calibrated. Two approaches have been considered. In Approach A, measured contact forces are applied to the model and all inverse dynamics loads are matched in order to get a physiological calibration of muscle parameters. …

Health and Sport Science Faculty Publications

This study compared the ergogenic effects of caffeine on men who were endurance trained to those who were untrained. The study was a double-blind, placebo-controlled crossover experimental design. Ten endurance trained men (mean age 24.4 ± 2.0 yrs, weight 79.4 ± 8.5 kg, predicted VO2 max 46.3 ± 1.8 mL·kg-1·min-1) and 10 untrained men (mean age 22.8 ± 1.9 yrs, weight 88.9 ± 9.9 kg, predicted VO2 max 37.6 ± 2.7 mL·kg-1·min-1) completed two cycle ergometer trials to exhaustion at 80% of their predicted workload max 30 min after ingesting either 5 mg·kg-1 of body weight of caffeine or a …

The Relationship Between Subjectively Motivational Music And Various Exercise Variables While Running At Maximal Speed, Michael Maloney

Honors College Theses

Purpose: To determine whether there are differences in steps/min/m, highest achieved exercise heart rate, average exercise heart rate, average running speed, estimated relative VO2, and RPE, while listening to subjectively motivating music, as compared to non-motivating music, while running at max speed. Methods: Eleven students enrolled at the University of Massachusetts Boston, considered “non-runners” from 19 to 34 years of age, ran at max speeds for 12-15 minutes, once while listening to a play-list of songs they ranked most motivating, and a second time on a separate day, while listening to a play-list of songs they ranked least …

A Miniaturised Spectrometer Device For The Detection Of Nitrogen Dioxide In An Urban Environment, Brian Devine

Doctoral

Monitoring of air pollutants, such as Nitrogen Dioxide (NO2), that are toxic or environmentally damaging is a key metric for environmental protection agencies worldwide. There is a constant need to develop new technologies and methodologies that provide real-time, low cost pollution measurements over a broad range of sampling sites, particularly in urban and industrial areas. Typically, detection of pollutants in urban environments is performed using a variety of techniques, many of which are expensive, require complex setups and are in fixed locations. The novel system presented in this thesis is designed for portable, low cost and in-situ detection of pollutants …

Strength, But Not Direction, Of Handedness Is Related To Height, Ruth E. Propper, Tad T. Brunyé, Karly Frank, Sean E. Mcgraw

Department of Psychology Faculty Scholarship and Creative Works

Left-handers are reputed to be shorter than right-handers. However, previous research has confounded handedness direction (left- versus right-handedness) with handedness strength (consistency with which one hand is chosen across a variety of tasks; consistent- versus inconsistent-handedness). Here, we support a relationship between handedness strength, but not direction, and stature, with increasing inconsistent-handedness associated with increasing self-reported height.

A Comparison Of Two Sock Types On Navicular Drop And Center Of Pressure Measurements In Standing, Walking, And Running, Ashlee Taylor

Theses and Dissertations

Introduction: The New Balance Core Low Cut Sock (New Balance Athletic Shoe, Inc. · Boston, MA United States) is one of many arch support socks out in the market. These socks have an elastic portion, called a Stability Fit Arch Support & Hold technology, which has been incorporated into the arch area of the sock. The company makes the following claim that the socks provide, "Gentle compression to support the arch, relieving arch-related pain and discomfort."1 If these socks do provide adequate arch support, then they would allow individuals the ability to have an inexpensive method of arch support that …

Balance Affects Prism Adaptation: Evidence From The Latent Aftereffect, Dobromir Dotov, Till D. Frank, Michael T. Turvey

Journal Articles

In prism adaptation experiments, the effect on throwing to a target is reduced (primary aftereffect is smaller) when the throwing condition with prisms removed (first test phase) is different from the throwing condition with prisms (the training phase). The missing adaptation, however, can be revealed through further testing (second test phase) in which the throwing condition during training is fully reinstated. We studied throwing underhand to a target flush with the floor. During training, participants wore left-shifting prism glasses while standing on the floor (Group 1) or on a balance board (Groups 2 and 3). Tests 1 and 2 following …

Which Type Of Sedentary Behaviour Intervention Is More Effective At Reducing Body Mass Index In Children? A Meta-Analytic Review, Y. Liao, J. Liao, C. P. Durand, G. F. Dunton

Kinesiology Faculty Publications & Presentations - Archive

Sedentary behaviour is emerging as an independent risk factor for paediatric obesity. Some evidence suggests that limiting sedentary behaviour alone could be effective in reducing body mass index (BMI) in children. However, whether adding physical activity and diet-focused components to sedentary behaviour reduction interventions could lead to an additive effect is unclear. This meta-analysis aims to assess the overall effect size of sedentary behaviour interventions on BMI reduction and to compare whether interventions that have multiple components (sedentary behaviour, physical activity and diet) have a higher mean effect size than interventions with single (sedentary behaviour) component. Included studies (n = …

Benefits Of Neuromuscular And Plyometric Training In Injury Prevention And Performance Enhancement, Bethanie Evans, David Kaiser

Journal of Undergraduate Research

A greater incidence of ACL injuries in women compared to men may stem from complex, interrelated factors, including hamstring-quadriceps strength imbalances, joint laxity, and neuromuscular deficits. While congenital joint laxity cannot be reversed, both hamstring/quadriceps imbalances and neuromuscular deficits have been shown to improve with functional neuromuscular training.1,2,3 Consequently, research needs to be conducted to quantitatively measure the changes to hamstring/quadriceps strength ratio as a result of neuromuscular functional training.

The Effects Of Multi-Modal Training In Athletes, William Brodegard, Dr. Roy Pat Vehrs

Journal of Undergraduate Research

In early March of last year I was suffered a stress injury from riding a bicycle. I had been training heavily, and was forced to stop training to allow my body to heal. During my time off of the bike, I stayed in shape by running and swimming. When I returned to the bicycle, I found that my level of fitness and biking ability had not depreciated as much as I had thought it might. Cross training had proven effective in maintaining my cycling skill level. I decided to research how cross training and cycling specific training effect the ability …

School Gardens, David W. Hey

Kinesiology and Public Health

School gardens can have great promise as they can positively impact children's food choices by improving their preferences for vegetables, increasing their nutrition knowledge, and prevent nutritionally related diseases (i.e., diabetes and obesity). In their natural state, fruits and vegetables have high water and fiber content and are low in calories and energy density. Additionally, it has been demonstrated that the use of a garden as part of an outdoor environmental studies program can have a beneficial impact on performance of standardized achievement tests, as well as attention and enthusiasm for learning in school children.

In June of 2004, national …

The Effects Of Long-Term Physical Activity On Food Attention Allocation In College Freshmen Women, Sharla Elizabeth Compton

Theses and Dissertations

Purpose: The purpose of this study was to examine the effects of long-term (24 weeks) physical activity on attention allocated toward food in college freshmen women. Methods: Seventy-nine freshmen college women wore a multi-function pedometer for 24 weeks after being randomly assigned to a daily step level: 10,000; 12,500; or 15,000. After at least 16 weeks of intervention, participants were given a cognitive viewing task (pictures of food and flowers) with the neural response measured using electroencephalogram (EEG) and event-related potentials (ERPs). P300s and LPPs are components of the ERP indicating increased attention to stimuli. Results: There was a significant …

Dip-Wrap Paraffin Wax And Moist Heat Pack Application And The Subsequent Rise In Tissue Temperatures, Jared K. Wilson, Dr. Kenneth L. Knight

Journal of Undergraduate Research

Paraffin wax baths are used by athletic trainers and physical therapists to apply superficial heat to the extremities of patients. The National Athletic Trainers Association (NATA) includes the use of paraffin wax as a required competency for students who are working toward certification. While the general consensus of many athletic trainers and textbooks1,2,3 is that paraffin wax application is an effective superficial heating modality, data is not available to back up such opinions. Not enough research has been done to quantify its heating effects or to compare it to other superficial heating modalities.

The Effect Of Dosage On The Rate Of Change In Young Adults With Tight Hamstrings, Katie Lynn Meek, Dr. Brent Feland

A variety of methods have been used to increase the range of motion and length of the hamstring muscles (Bandy et al. (1997), Feland et al. (2001), Graham, et. al. (year unknown), Johnson et al. (1997), Sherry et al. (2004), Willy et al. (2001)). The purpose of this study was to determine which method of total time and dosage was most effective in increasing the range of motion and flexibility of the hamstring muscle.

A Biomechanical Evaluation Of A Novel Mobile Walking Device, Thomas D. Bateman, Dr. Matthew K. Seeley

Journal of Undergraduate Research

Many individuals rely on crutches to help them walk. Those relying on traditional crutches often suffer from upper-extremity pathologies as well as psychological detriments.1 Additionally, those using crutches typically suffer from increased energy expenditures during locomotion.2 The Millennial Crutch (Figure 1) is a proposed alternative to the traditional crutch. The producers of the Millennial Crutch purport that Millennial Crutch use eliminates many of the disadvantages of traditional crutch use.

Functional Morphology Of Rat Hands And Feet: Correlation With The Ability To Grip Tree Branches During Locomotion, Jessica E. Fonce, Andrew R. Lammers

Undergraduate Research Posters 2013

Anatomy and function are usually closely related. Since locomotion on tree branches is common among mammals, we expect to find that the anatomy of the hands and feet is well-suited toward gripping narrow, cylindrical, branch-like substrates. We hypothesize that the ability of rats to grip arboreal supports relies on musculature responsible for adducting the first digit (thumb and big toe) and opposing medial-most and lateral-most digits. We dissected the hands and feet of four rat cadavers. There is a substantial muscle that may be responsible for the flexion/adduction of the thumb in the hands. We also found lumbricals, and dorsal …
