    Anterior Cruciate Ligament Neuromuscular Training Protocol of the Core and Hip Musculature: Effects On Female Athletes' Landing Mechanics
    (North Dakota State University, 2013) Young, Charley John
    Landing is a dynamic activity and considered one of the leading causes of noncontact ACL injuries. Poor biomechanics during dynamic activity resulting from neuromuscular imbalances may contribute to ACL injury. The purpose of this study was to determine if a trunk and hip neuromuscular training program for female high school athletes facilitates neuromuscular changes during landing mechanics. Participants were assessed using the Landing Error Scoring System (LESS) after a drop box jump, pre-test, mid-test, and post-test. A high LESS score indicates poor landing mechanics. Additionally, participants filled out a survey regarding their perceptions of neuromuscular changes and their landing mechanics. LESS scores decreased significantly between pre to post testing. Participants believed their landing mechanics improved, they became stronger, and they become more aware of their body. Results showed that an eight week hip and trunk neuromuscular program improved landing mechanics and may help decrease noncontact ACL injuries in this population.

    Cramp Threshold Frequency in a Fatgiued Flexor Hallicus Longus Compared to a Rested Flexor Hallicus Longus
    (North Dakota State University, 2014) Drayton, Alexandra Marjorie
    Muscle fatigue is thought to cause a person’s exercise associated muscle cramps (EAMCs). However, there is little support that fatigue is the reason EAMCs occur. We examined if a fatigued muscle would make it more susceptible to an EAMC. Subjects were exposed to a cramping protocol, which included two seconds of stimulation with a minute rest until a muscle cramp was induced. The participant rested for 30 minutes and then completed a fatigue protocol. The subject performed reps of toe curls against a resistance band (sets of 10 curls with a one minute break in between sets) until muscle failure. Following fatigue, participants immediately completed the cramping protocol. Paired t-test analysis revealed that the change in cramp threshold frequency was not statistically significantly different in a fatigued flexor hallicus longus than in a rested flexor hallicus longus (t(9)= 1.69, p > .05). Although not statistically significant, results indicated a difference between the mean cramp threshold frequency in a fatigued flexor hallicus longus (25.80Hz ± 7.33) when compared to a rested flexor hallicus longus (28.20Hz ± 7.91) condition. Fatigue does not play a factor on EAMCs. Future studies should focus on a larger sample size and evaluation of other possible factors that influence EAMCs.
