“…Both of these actions require a reorganisation of the muscular recruitment pattern [10][11][12] . For example, standing has been shown to increase the level of activity in individual (proximal) upper leg muscles as well as overall muscle activation, and to alterthe timing of muscle activation 11 . Interestingly, comparable changes have not been seen in muscles of the lower leg 11 .…”

“…A previous study [27] allows for a positive verification of these observations; the authors of that study compared the electrical activity of the muscles for various angles of a ground slope (4%, 7%, 10%), and it transpired that the muscle which performed the least work was the vastus medialis, whereas the muscle with the highest percentage contribution to the cycle was the gastrocnemius muscle. Chapman et al [19] examined cyclists and found that the gastrocnemius caput laterale was the most active muscle in all the study participants.…”

Introduction. The aim of this study was to measure the duration of biopotentials in selected muscles of the lower limbs, evaluate the time of elevated bioelectrical activity in these muscles, and identify similarities and differences in electrical phenomena that occur in the muscles for various external settings of a cycle ergometer. Material and methods. The study examined 10 healthy people (5 women and 5 men) aged from 20 to 30 years. A cycle ergometer and EMG apparatus were used in the experiment. The bioelectrical activity of six muscles of the lower limbs (rectus femoris, vastus medialis, tibialis anterior, biceps femoris, gastrocnemius caput mediale, and gastrocnemius caput laterale) was recorded for four different settings of the cycle ergometer (variable saddle height and method of foot attachment to pedals). The EMG records were presented with reference to the bicycle crankset rotation cycle. Conclusions. The study found that changing the height of the saddle of the cycle ergometer and the use of toe clips in the pedals caused changes in bioelectrical activity in the muscles. The adjustment of saddle height affected the duration of potentials more noticeably than the use of toe clips. Furthermore, only one period of elevated electrical activity in the muscles of the lower limbs was found in the pedalling cycle. The longest time of the presence of action potentials was recorded for the m. gastrocnemius caput laterale, whereas the shortest time was observed in the m. vastus medialis.

“…The economy of cycling can be measured by physiological methods as the ratio of metabolic energy transformation to mechanical work (Broker & Gregor, 1994;Ettema & Lorås, 2009) or to integrated muscular activity of main (leg) muscle groups (Duc et al, 2008). The biomechanical effectiveness of cycling pedalling technique is traditionally measured as the ratio between tangential (perpendicular to bicycle crank arm) force to the resultant force applied to the pedals (Gonzales & Hull, 1989; Coyle et al, 1991).…”

The purpose of this study was to characterise the changes in the power of the normalised ground reaction forces and COP swaying, as measures of the cycling stability and effectiveness of full body motion during an incremental cycling exercise; and to examine the relationships between cycling specific postural stability and cyclists ability to perform functional movements, measured by the FMS test.38 competitive road cyclists (19.2±2.3 yrs., 181.7±6.6 cm, 74.3±7.3 kg) performed Functional Movement Screen (FMS) test to evaluate their musculoskeletal state. Experimental cycling exercise was performed using the cyclist's personal racing bikes mounted on the cycling ergometer Cyclus 2, which were fixed on two Kistler 9286B force plate. The 6 ground reaction force (GRF) components (3 linear and 3 angular), COP movement deviation and sway velocity were measured during incremental cycling exercise (step 2 min, increment 25W). Postural stability measures were calculated as power corrected standard deviations of center of pressure (COP) and GRF components signals during 30 sec cycling in every incremental step. The paired t-test was used to control differences in postural stability measures between intensity levels and correlation analyses was used to evaluate relationships between postural stability and FMS scores. Results of the study indicate that most integrative cycling specific posture stability measure is COP sway velocity that is also most sensitive predictor of cyclist's musculoskeletal state, measured by the FMS test. During an incremental cycling exercise the power normalised postural swaying decreased up to the intensity at the level of anaerobic threshold and during the level of the maximal aerobic power the postural stability decreased significantly.
