Skeletal damage, repair and adaptation to uphill and downhill running in humans.Krafft, Ingrid January 1994 (has links)
A Dissertation Submitted to the Department of Physiology,
University of the Witwatersrand,Johannesburg
for the Degree of Master ot Science / Extensive disruption of muscle fibres has been shown to occur after short term eccentric
exercise where high mechanical forces are generated. This study tested whether downhill
running acts as a stimulus for inducing eccentric damage, and results in greater muscle
damage and deterioration in muscular performance than an equal workload of uphill
running. The study aimed at determining whether an adaptation or training effect takes
place such that the muscle is more resistant to the damaging effects of a repeated bout of
the same exercise. In. addition, the study aimed at determining whether the lower muscle
volumes and forces of muscular contractions in females compared to males, makes
females less susceptible to the damaging effects of eccentric contraction.(Abbreviation abstract) / Andrew Chakane 2019

Evaluation of Non-Contact ACL and MCL Strain on Lower Extremities Using a Hybrid Cadaveric System Simulating High Impact Athletic ActivatesUnknown Date (has links)
In this thesis, adaptations were made on the Hybrid Cadaveric System to
accommodate new testing ramifications. The tests simulated dynamic loading (jump
landings) from a 1ft. height with various degrees of valgus (fixed hamstring and
quadricep forces) and various Quadricep (Q) and Hamstring (H) forces (fixed degrees of
valgus) to determine how the Anterior Cruciate Ligament (ACL) and Medial Collateral
Ligament (MCL) behave. The tests performed included 0Q 0H, 100Q 0H, 300Q 0H,
300Q 100H, and 5°, 15°, 25° of valgus. To determine the strain behavior of the ACL and
MCL a variety of equipment was used, including electromagnetic force plate to take
impact reading, cables used to create loading on the quadriceps and hamstrings, and two
Differential Variance Resistance Transducers (DVRTs). These ultimately generated ACL
and MCL strain allowing for a variety of strain comparisons under various circumstances.
It was concluded that in a few cases there were statistically significant differences in
strain for the ACL and MCL when applying various quadricep and hamstring forces (fixed valgus). It was also found that only statistical significance was present in ACL
strain when comparing degrees of valgus (fixed quadricep and hamstring forces). The
research concluded that muscle activation reduces strain on the ACL and MCL in these
testing scenarios. It was also established that degrees of valgus effects the ACL but is
negligible for the MCL. However, due to complications and variables, further testing is
needed to increase accuracy and supply more definitive results. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

The Knee injuries in women soccer players in South AfricaMohamed, Ehab Elsayed 29 May 2010 (has links)
Thesis (MSc (Physiotherapy))--University of Limpopo (Medunsa Campus), 2010. / The knee Injuries in Women Soccer Players in South Africa
The Knee is a common site for injuries in soccer players. The reasons for the increased
rates of knee injuries in women soccer players are not clear, but some theories suggested the
reason to lie in the difference in anatomy. This research investigate the prevalence of knee
injuries in women soccer players in South Africa and sought to find out whether three of the
anatomical factors (Q-angle, pelvic width and Intercondylar notch width) have a role in
increasing knee injuries in these individuals. The study design was case –control study.
Methodology: Twenty four players of South Africa women soccer team (Under 23)
participated in this study. X-rays of the hip were taken and the Q-angles were thereafter
measured manually. Association between anatomical factors and knee injuries were
determined.
The result of this study showed that 17% of the players were having non contact knee
injuries. Statistical analysis showed no significant relation between knee injuries among
women soccer players and each of the anatomical factors. The P-values of both t-test and
ANOVA test were larger than the 0.05 level of significance. The study found that the
prevalence of knee injuries among the young women playing for the South African national
team U-23 was relatively high. However, this study could not identify significant relationship
between the anatomical risk factors and the incidences of knee injuries among the
participants.

Epidemiology and management of basketball related injuries in RwandaHakizimana, Moussa January 2005 (has links)
Basketball continues to increase in popularity worldwide as a participation sport at all levels of play, from recreational to professional. Each year, more than 1.6 million basketball-related injuries are treated in hospitals, doctor's offices and emergency rooms in North America. In Rwanda, basketball and volleyball are the second popular sports, following football. The aim of the study was to investigate the prevalence, mechanisms, nature and management of basketball-related injuries in Rwanda. / Magister Scientiae (Physiotherapy) - MSc(Physio)
