“…According to the progressive decrease (P<0.01) in FCC and the progressive increase (P<0.01) of EMGi (VL) and EMGi (RF) throughout the 2-hour cycling at constant power, the muscular strategy which consisted of greater forces applied to the pedals with a reduction in the pedalling rate (Patterson et Moreno, 1990) as the exercise duration increased, appeared to contradict results regarding a decrease in post exercise maximal muscular strength. A change in muscular type fibre recruitment during the 2-hour cycling exercise is often put forward.…”

“…Given a constant work load, the blood lactate increases more at intensities higher than 200 watts and cadences from 100 to 120 rpm [12,13,26]. The change in blood lactate at different cadences is mainly due to the activation and recruitment of different muscle fibre types [30,31]. These facts depend on the activation of fast-twitch muscle fibres in the exercise program [32].…”

Abstract:The importance of the central nervous system in endurance exercise has not yet been exhaustively investigated because of difficulties in measuring cortical parameters in sport science. During exercise there are a lot of artifacts and perturbations which can affect signal quality of cortical brain activity. The technical developments of surface electroencephalography (EEG) minimize such influences during standardized test conditions on a bicycle ergometer. The aim of this study was to investigate how movement frequency affects cortical brain activity and established physiological parameters during exercise. In cycling peak performance is affected by cadence. The analysis of brain cortical activity might lead to new insights in the relation of power and cadence. In a laboratory study sixteen male, endurance-trained cyclists completed a 60 min endurance exercise on a high-performance bicycle ergometer. Cadence was changed every 10 min (90-120-60-120-60-90 rpm). EEG was used to analyze changes in cortical brain activity. Furthermore, heart rate, blood lactate and rate of perceived exertion (RPE) were measured after each cadence change. The results indicate that heart rate, blood lactate and RPE were higher at 120 rpm compared to 60 rpm. The spectral EEG power increased statistically significantly in the alpha-2 and beta-2 frequency range by changing cadence from 60 to 120 rpm. By lowering the cadence from 120 to 60 rpm the spectral power dropped statistically significantly in all analyzed EEG frequency bands. The data also showed a statistically significant decrease of spectral EEG power in all frequency ranges over time. In conclusion, the analyzed EEG data indicate that cadence should be considered as an independent exercise normative in the training process, because it directly influences metabolic, cardiac and cortical parameters.

“…The application of pedaling forces has been previously studied in normal (12,13) and prolonged cycling conditions (14). The typical pedaling stroke is separated into the effective (force application perpendicular to crank arm) and ineffective (force application parallel with crank arm) components (1).…”
