A 2.5min cold water immersion improves prolonged intermittent sprint performance
Egana, Mikel (2019)Objectives: We investigated if cold water immersion (CWI) affects exercise performance during a prolonged intermittent sprint test (IST), designed to mimic activity patterns of team-sports. Design: Randomized-crossover ... -
Effect of body tilt angle on fatigue and EMG activities in lower limbs during cycling
Egana, Mikel (2010)This study compared the rate of fatigue and lower limb EMG activities during high-intensity constantload cycling in upright and supine postures. Eleven active males performed seven cycling exercise tests: one upright graded ... -
Effect of low recumbent angle on cycling performance, fatigue and VO2 kinetics.
Egana, Mikel (2013)Purpose: This study aimed to examine the effect of the degree of inclination from upright to supine postures on cycling performance, fatigue, and oxygen uptake (V˙O(2)) kinetics. Methods: In experiment 1, 10 subjects ... -
Influence of type 2 diabetes on muscle deoxygenation during ramp incremental cycle exercise
Egana, Mikel (2019)We tested the hypothesis that type 2 diabetes (T2D) alters the profile of muscle fractional oxygen (O2) extraction (near-infrared spectroscopy) during incremental cycle exercise. Seventeen middle-aged individuals with ... -
Low-volume HIIT and MICT speed VO2 kinetics during high-intensity "work-to-work" cycling with a similar time-course in type 2 diabetes
Gildea, Norita; Egana, Mikel (2022)We assessed the rates of adjustment in oxygen uptake (V̇o2) and muscle deoxygenation [i.e., deoxygenated hemoglobin and myoglobin, (HHb + Mb)] during the on-transition to high-intensity cycling initiated from an elevated ... -
Priming exercise accelerates oxygen uptake kinetics during high-intensity cycle exercise in middle-aged individuals with type 2 diabetes
Egana, Mikel (2022)Background: The primary phase time constant of pulmonary oxygen uptake kinetics ( ⋅VO2 τ p) during submaximal efforts is longer in middle-aged people with type 2 diabetes (T2D), partly due to limitations in oxygen supply ... -
Priming exercise accelerates pulmonary oxygen uptake kinetics during "work-to-work" cycle exercise in middle-aged individuals with type 2 diabetes
Egana, Mikel (2021)Purpose: The time constant of phase II pulmonary oxygen uptake kinetics ([Formula: see text]) is increased when high-intensity exercise is initiated from an elevated baseline (work-to-work). A high-intensity priming exercise ...
