Different Effects Of Static And Vibrating Foam Rollers On Ankle Plantar Flexion Flexibility And Neuromuscular Activation, Brianna G. Mazzei
Different Effects Of Static And Vibrating Foam Rollers On Ankle Plantar Flexion Flexibility And Neuromuscular Activation, Brianna G. Mazzei
Honors College Theses
The relatively new implementation of vibration into foam rollers was developed in response to the positive feedback of whole-body vibration treatment and foam rolling therapy. The purpose of the study is to research the changes in range of motion and myoelectric activity of the ankle dorsiflexors in female NCAA Division I swimmers when using a vibrating foam roller in comparison to a static foam roller. Combining the self-myofascial release with the increased blood flow and muscle temperature exerted from vibration could possibly enhance the effects of foam-rolling treatment. The different effects of ankle flexibility and motor unit activation after static …
Lower Limb Fatigue Asymmetry Of Preferred And Non-Preferred Legs After A Repeated-Sprint Test In Football Players With Previous Hamstring Injury, Cameron Lord
Theses: Doctorates and Masters
Football is the most widely played sport in the world and is thus associated with the highest total number of injuries of all sports. 12% of all football injuries are to the hamstrings, as this muscle group is subjected to constant stress during training and match play performance (Ekstrand, Hägglund, Waldén, 2011; Woods, Hawkins, Maltby, Hulse, Thomas & Hodson, 2004). While the influence of limb dominance has been extensively examined as a risk factor for injury in upper limb-dominant sports (e.g. badminton, tennis and baseball), little research has focussed on the dominance in the lower limbs. Since almost all footballers …
The Effects Of Movement Based Interventions On Doms And Muscle Damage Following Eccentric Exercise, Zainal A. Zainuddin
The Effects Of Movement Based Interventions On Doms And Muscle Damage Following Eccentric Exercise, Zainal A. Zainuddin
Theses: Doctorates and Masters
Delayed onset muscle soreness (DOMS) is a common symptom experienced by most adults following unaccustomed exercise. It is known that DOMS is peculiar to eccentric exercise that results in muscle damage which is characterized by prolonged loss of muscle function. DOMS and subsequent impaired muscle function, reduces the ability to maximize performance of daily living tasks, and has negative effects on sports adherence and activity based healthy lifestyle. Thus, treatments to ameliorate DOMS and enhance recovery of muscle function are important.
Proprioceptive And Muscle Activation Changes In Triceps Surae Associated With Exercise Induced Muscle Damage, Carmel Nottle
Proprioceptive And Muscle Activation Changes In Triceps Surae Associated With Exercise Induced Muscle Damage, Carmel Nottle
Theses: Doctorates and Masters
The aim of this thesis was to examine proprioceptive and activation changes that occur in triceps surae in response to exercise induced muscle damage (EIMD). While proprioceptive changes have previously been demonstrated in association with EIMD, the present investigation examined the role of a number of potential contributing factors to these changes, following both single and repeated bouts of eccentric exercise.
Force And Electromyographic Responses To Ergometer Rowing, Darryl A. Turner
Force And Electromyographic Responses To Ergometer Rowing, Darryl A. Turner
Theses: Doctorates and Masters
During many athletic events, fatigue influences the physiological and biomechanical characteristics of performance. For optimal performance in events such as rowing, athletes must maintain a skilfully co-ordinated movement technique. The ability to produce high force outputs during repetitive contractions is influenced by fatigue and dependent on a number of factors including neuromuscular activities. Neuromuscular activation may be expressed by amplitude and frequency characteristics of the electromyographic signal (EMG) sample from the muscle. During sustained isometric contractions, changes in EMG characteristics are related to changes in force, which may be useful in monitoring the fatigue process (Basmajian, 1974: De Luca, 1985). …
Changes In Muscular Power Associated With Delayed Onset Muscle Soreness, Carmel Nottle
Changes In Muscular Power Associated With Delayed Onset Muscle Soreness, Carmel Nottle
Theses : Honours
The aims of the this study were to investigate the effects of delayed onset muscle soreness (DOMS) following downhill running on cycling power output and to determine the extent of any relationships between power output, strength, and DOMS. 12 active male subjects (aged 18-25 years) were randomly assigned to either a test (n=7) or control (n=5) group. The test group performed a 5 x 8 minute downhill running protocol at a grade of -7% and a speed corresponding to 80% of the subjects age predicted heart rate maximum. Measurements of isometric knee extension and flexion strength, peak and average cycling …
Effect Of Exercise Induced Muscle Soreness On The Motor Control Properties Of The Biceps Brachii, Alan J. Pearce
Effect Of Exercise Induced Muscle Soreness On The Motor Control Properties Of The Biceps Brachii, Alan J. Pearce
Theses : Honours
The objective of this study was to note the time course changes for up to 28 days on the motor control properties of biceps brachii muscle following a bout of eccentric exercise. Eight subjects (5 male, 25-40 years of age) performed 35 maximal voluntary eccentric contractions with the non-preferred arm of the elbow flexors through 130° of extension of 90°s-1. Voluntary electromyographic (EMG) activity and motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) were recorded via surface electrodes placed over the belly of the biceps brachii muscle. Maximal isometric strength was measured at 90° elbow flexion. …
