The lower limb muscle activity and lumbo-pelvic movement control in soccer players: a matched case control studyRoos, Riali January 2017 (has links)
A Research Report submitted to the Faculty of
Health Sciences, University of the Witwatersrand
Gauteng, 2017 / Background
Soccer is a sport that is gaining in popularity in the elite and non-elite populations worldwide.
As a result, the number of injuries in soccer is increasing. Hamstring injuries in particular,
with a reported incidence rate as high as 63%, are of significant concern. Most hamstring
injuries tend to occur during the swing phase of sprinting when hamstring activity is at its
highest. As the speed of sprinting increases, greater mobility in the lumbo-pelvic area is
required to maximise sprinting efficiency. Any abnormal or dysfunctional lumbo-pelvic
movement during this phase could induce pain and hamstring injury. Lumbo-pelvic
movement control dysfunction may therefore indirectly link abnormal lumbar spine
movement to lumbo-pelvic pain and hamstring injury.
The first aim of this study was to compare the performance of the erector spinae, gluteus
maximus, hamstrings (biceps femoris) and quadriceps (rectus femoris) muscles in soccer
players, with and without recent hamstring injuries, while performing isometric contractions,
a functional squat and sprinting. The study’s second aim was to compare lumbo-pelvic
movement control in soccer players with and without recent hamstring injuries.
Method
Thirty soccer players were selected to participate in this study. Fifteen were assigned to the
injured group and 15 to an uninjured group. The injured group comprised players who had
sustained a hamstring injury six months prior to the research and who had partially returned
to training, and the uninjured group comprised players with no recent hamstring injuries and
who were actively involved in full training. Players were matched in respect of age, height,
weight and playing position.
All players gave informed written consent, completed the physical activity, training and
injury questionnaire, and the Oslo hamstring injury questionnaire. Physical tests, which
included isometric contraction of the erector spinae, gluteus maximus, hamstrings (biceps
femoris) and quadriceps (rectus femoris) muscles, a functional squat and a thirty-metre sprint
were done. Muscle activity during these tests was recorded via electromyography (EMG). To
determine the lumbo-pelvic movement control of the players, the dorsal pelvic tilt, waiter’s
bow, one leg stand and prone knee bend tests were used.
Cohen's d (parametric) and Spearman’s correlation coefficient (nonparametric) were used to
calculate the effect size, and the Chi-square test and Fisher’s exact to analyse the lumbopelvic
movement control data. To establish a statistical significance, the p-value of the study
was set at p<0.05.
Results
EMG muscle activity during isometric contractions was lower in the erector spinae muscles
(p=0.04) and biceps femoris muscle (p=0.02) of the injured group. Both these findings were
statistically significant. There was no statistically significant difference in muscle activity
during the functional squat between the study and uninjured groups. The results of the EMG
activity in the thirty-metre sprint were determined to be significant as they demonstrated that
the hamstring muscle (p=0.01) activation in the injured group was decreased in comparison
with the uninjured group.
During the performance of the lumbo-pelvic test, no association was found between the two
groups in the dorsal pelvic tilt and one leg stand. The performance of the waiter’s bow
(p=0.01) and prone knee bend (p=0.004) revealed statistically significant differences between
the study and uninjured groups. The majority of the players in the injured group performed
both of these functional tests incorrectly (WB n=10; PKB n=14).
Conclusion
The study found that the hamstring muscle is at great risk of injury during eccentric
contraction of the hamstring muscles. This can be associated with poor lumbo-pelvic
movement control, as the load on the hamstring muscle is increased to provide intersegmental
stability around the neutral zone, the area of high spinal flexibility. / MT2017

Habitat Use of Shovelnose Sturgeon Scaphirhynchus Platorynchus in the Lower Mississippi RiverKroboth, Patrick Thomas 13 December 2014 (has links)
The habitat requirements of shovelnose sturgeon populations are unknown for the lower Mississippi River. Active acoustic telemetry was used to measure temporal variation in habitat use of shovelnose sturgeon and preference for depth, surface current velocity, and riverbed rugosity and slope by the population and within sandbar microhabitats. Shovelnose sturgeon occupied habitats differently throughout the year; and, within habitats, areas of moderate depth and surface current velocity and smooth riverbed were preferred. Within sandbars, environmental conditions did not differ from the surrounding environment, yet frequent aggregations of individuals in the lower portion of sandbars often in close proximity suggest habitat preference at a scale greater than the 5 ha measured. Results of this study provide information on seasonal habitat use patterns and methods that can be applied to a long-term dataset to identify the habitat requirements of shovelnose sturgeon.

Deciphering the Age and Significance of the Cora Lake Shear Zone: Athabasca Granulite Terrane, Northern SaskatchewanRegan, Sean P 01 January 2013 (has links) (PDF)
Interpreting the tectonic significance of high strain zones requires detailed knowledge of the P-T-t-D history of rocks on either side and of tectonized rocks within the shear zone. In-situ monazite geochronology is particularly useful because it generates a time-integrated framework of metamorphism and fabric development. This can be achieved by correlating monazite compositional domains with the growth and consumption of major phases. Furthermore, monazite can be a fabric forming mineral, and can be directly linked to structural fabrics and kinematics. The Cora Lake shear zone (CLsz) represents a major lithotectonic discontinuity within the deep crustal Athabasca Granulite terrain, and preserves intense mylonitic to ultramylonitic fabrics. The 3-5 km wide CLsz strikes ~231°, and dips ~62° to the Northwest, has a moderately plunging stretching lineation (SW trend) with abundant sinistral kinematic indicators. These data indicate oblique extension with NW hanging wall down and to the SW relative to the SE footwall. The NW hangingwall is dominated by the ca. 2.6 Ga charnockitic Mary batholith. The southeastern footwall is primarily underlain by the heterogeneous ca. 3.3-3.0 Ga Chipman tonaite straight gneiss. Although both share common Archean (ca. 2.55 Ga) and Paleoproterozoic (ca. 1.9 Ga) deformation events, the style and P-T conditions of deformation are different. The earliest phase of deformation within the NW hangingwall consists of a penetrative subhorizontal flow fabric at 0.9 GPa and ~725°C (2.56 Ga), but folding in the SE footwall associated with the development of a strong upright axially planar fabric at 1.35 GPa and 850°C. Deformation at ca 1.9 Ga was characterized by upright folding, similar in orientation, in both hangingwall (0.9 GPa; 725°C) and footwall (1.17 GPa; 825°C). Deformation related to the CLsz occurred at 1880 Ma (0.9-1.06 GPa; ~775°C), and is responsible for juxtaposing two levels of lower crust. The Cora Lake shear zone is interpreted to be the culmination of a trend of increased strength, localization, strain partitioning, and vertical coupling. Furthermore, the CLsz overprints fabrics from each wall, marks the development of a major lateral lithotectonic discontinuity, and an introduction of major structural and compositional heterogeneity within the lower continental crust.

Sedimentology, Ichnology and High-Resolution Allostratigraphy of the Lower Cretaceous Viking Fonnation, Central Alberta, CanadaBurton, James 05 1900 (has links)
<p> The Lower Cretaceous (Upper Albian) Viking Formation of central Alberta
contains numerous linear sandbodies and fewer large irregularly-shaped sandbodies. Most
studies to date have focused on individual sandbodies, leaving their interrelationships
largely unknown. Developing a high-resolution allostratigraphy for the Viking of central
Alberta allows mapping of regional bounding discontinuities and the definition of distinct
allomembers. Placement of the Viking hydrocarbon fields within this framework permits
an understanding of the exact stratigraphic relationships of the various fields. </p> <p> Examination of 120 cores and numerous well log correlations suggests the
existence of four regionally mappable bounding discontinuities (BDl-4) which separate
five distinct allomembers (I-V). Sandbodies within these allomembers were deposited in a
variety of sedimentologically distinct environments. These include 'regional Viking'
offshore to shoreface sandstones, prograding highstand shoreface sediments, transgressive
incised shoreface sediments, and forced regressive, onlapping shoreface 'tongues'. The
series of linear trending hydrocarbon fields from Joffre to Chain are also stratigraphically
distinct. The sandbodies exist at five separate stratigraphic horizons and therefore are not
all part of the same incised shoreface deposits. </p> <p> The four regional bounding discontinuities are interpreted as transgressive surfaces
of erosion formed by four separate drops and subsequent rises of relative sea level. These fluctuations were greater than 30m and each complete cycle occurred over roughly
375,000 years. </p> / Thesis / Master of Science (MSc)

An evaluation of aquatic therapy as a treatment for lower back painOlson, Daniel A. 01 May 2011 (has links)
Lower back pain (LBP) is a medical condition that will affect most of us at some point in our lives. Several medical causes have been identified for LBP, yet the large majority of LBP patients do not receive a specific diagnosis. These patients use up a large majority of health care resources, and accumulate billions of dollars in medical costs in countries throughout the globe. In recent years, an increasing focus has been placed on the idea that aquatic therapy may be an effective therapy for LBP patients. Exercise therapy has already proven itself as an effective means for treating LBP. Thus, combined with the unique properties of water, experts believe that aquatic therapy is the future of LBP treatment. This thesis aims to explore the efficacy of aquatic therapy as a treatment for LBP. Through the analysis of controlled peer-reviewed studies, scholarly information databases, and historical data on LBP treatment, this thesis evaluates the relationship between aquatic therapy and LBP in its entirety. Scientific properties of water have shown its many uses in rehabilitative therapy treatments. Water, in theory, is able to manipulate the exercise environment to allow for more substantial progress to be made. In studies where aquatic therapy was tested versus no treatment, aquatic therapy proved to be a more efficient and effective option. Still, when placed against other therapies, aquatic therapy did not always prove more effective. While the analyzed studies support the idea that aquatic therapy is an effective treatment for LBP, further research is needed to determine how aquatic therapy holds up against other forms of treatment.
