The Effect of Varying Cadence in Cycle Ergometry on Submaximal Predictions of Peak Oxygen Uptake
… cadence had on the ability of a submaximal cycle ergometry test to accurately predict peak oxygen uptake (VO2) using the standard YMCA protocol workloads. There has been limited scholarship investigating the effect that varying cadence has on trained cyclists and almost none on untrained …

Ratings of perceived exertion during steady-state exercise using leg-only versus arm-and-leg cycle ergometry
… graded maximal exercise test on a Monark 880 LE cycle ergometer. Exercise intensity during two subsequent 30-minute exercise treatments was then maintained at the HR corresponding to 70% of the subject's tested functional capacity (VO2max). The exercise treatments were two randomized bouts …

Effects of G-trainer, cycle ergometry, and stretching on physiological and performance markers of recovery from endurance exercise.
… completed 30 minutes of AlterG G-trainer or cycle ergometry (at ~40% VO2max) or static stretching exercises. A significant main effect for time was detected for lactate (p = 0.010) and cortisol (0.039) post-exercise. No other main effects for time,treatment or treatment by time interaction …

The effect of measurement technique, and load and fatigue, with changes in crank arm length, on lower limb kinematics in cycle ergometry
… in crank arm length, on lower limb kinematics in cycle ergometry; Pedal forces in a cycling task can be defined by joint moment cost functions which describe the optimal relationship between pedalling rate and bicycle-rider geometry for any given power level. In a task where power level changes, …

VO2Max Comparison Between Seated and Standing Ergometry
… Previous studies show V02max during standing cycle ergometry protocols and treadmill protocols to be similar, while seated cycle ergometry V02tnax values are lower. Conversely, other studies show seated and standing cycle ergometry V02max to be comparable. Because previous studies are …

Cardiorespiratory responses to altered rider position with conventional and aerodynamic handlebars
… three rider positions while undergoing maximal cycle ergometry. The positions were determined by the position of the hands on the handlebars and the posture of the upper body: upright (UP), and drop position (DP) with conventional racing handlebars, and an aerodynamic tuck (AT) using Scott DH …

Oxygen Uptake Kinetics in Severe Intensity Exercise
… mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit fatigue in ~3 to 10 min. A simple …

Optimisation considerations for the measurement of human muscle power
High intensity cycle ergometer exercise tests are designed to measure power outputs. Most of the tests utilise resistive forces that are based on total-body mass values (TBM). Conceptually, selecting an optimal resistive force based on total-body mass may not be the best approach. Resistive forces …

Effects of α1-receptor blockade on the hemodynamic responses to exercise in young normotensives and hypertensives
… college-age males underwent two 30 min bouts of cycle ergometry exercise at 50% V02Pk in a warm (25°C, 50% rh) environment; one bout occurred followed α1-receptor blockade with prazosin (HTN-α, NTN-α) and the other following placebo administration (HTN-p, NTN-p). At rest, HTN-p exhibited an …

CARE-ing for Concussions: Development of the Calgary Adapted aRm Ergometer (CARE) Test: A Novel Upper-Body Post-Concussion Exertion Test
… Concussion Bike Test and the Calgary Concussion Cycle Test (CCCT). However, all of these exertion tests are focused on exercise performed with the lower body and there currently does not exist an upper body specific post-concussion exertion protocol to help inform recovery recommendations. To …

THE RELATIONSHIP BETWEEN AEROBIC TRAINING AND CARDIOVASCULAR RESPONSE TO EXERCISE
… and higher resting upright stroke volume. During cycle exercise both groups had similar increases in heart rate and decreases in stroke volume in response to venous occlusion. Also, during cycle exercise, heart rate and stroke volume were significantly higher at high cadence (80 rpm) than that at …
