High-Intensity Interval Eccentric Cycling: Acute And Chronic Effects, Marcin Lipski
High-Intensity Interval Eccentric Cycling: Acute And Chronic Effects, Marcin Lipski
Theses: Doctorates and Masters
Eccentric cycling training has been prescribed in continuous and low intensities protocols, based on concentric cycling parameters. While the lower metabolic demand of eccentric than concentric cycling is advantageous for clinical or ‘at-risk’ populations, it is a disadvantage for cardiovascular and pulmonary adaptations. High-intensity interval protocols may increase both, strength and endurance. Thus, this research project compared i) an incremental concentric and eccentric cycling test until exhaustion for the relationship between power output and physiological parameters <Study1>; ii) interval and continuous eccentric cycling protocols for oxygen consumption, perceived exertion and enjoyment <Study 2>; and iii) aerobic performance, muscle …
Braking Ground Reaction Force During 90deg Sidestep Cut And Its Relationship To Leg Muscle Strength, Walter Yu
Braking Ground Reaction Force During 90deg Sidestep Cut And Its Relationship To Leg Muscle Strength, Walter Yu
Theses: Doctorates and Masters
Previous studies on change of direction (COD) have reported that braking is an important factor for COD performance. However, previous studies have focused on the plant step and the penultimate step (PEN), thus little is known about deceleration before these steps. This study compared ground reaction forces (GRF) of two braking steps, the PEN and the step prior to PEN (PEN-1), the entry and exit velocity of the COD, and muscle function measures (leg press and leg curl one-repetition maximum, isometric and isokinetic strength, and drop jump performance) between faster and slower participants for a 90o sidestep cut. This …
