Saddle position affects mechanical variables during submaximal cycling, but little is known about its effect on mechanical performance during maximal cycling. Therefore, this study relates saddle position to experimentally obtained maximal power output and theoretically calculated moment generating capacity of hip, knee and ankle muscles during isokinetic cycling. Ten subjects performed maximal cycling efforts (5 s at 100 rpm) at different saddle positions varying ± 2 cm around the in…

Isokinetic muscle strength and short term cycling power of road cyclists

The strongest muscle group in road cyclists are hip Extensors, sprinting power has strongest correlation with hip extensors strength at angular speed of 180o/s, relationship between sprintingPower and strength of hip flexors was statistically insignificant.

Sprint cycling performance and asymmetry

The highest asymmetries were found in cyclist’s upper body kinematics and at the same time the most symmetrical were knee extensors strength values, but both parameters were negatively and significantly correlated with the performance of sprint cycling.

The Influence of Bicycle Geometry on Time-Trial Positioning Kinematics and Markers of Performance

These results can serve as a starting point for understanding the interactions between bicycle geometry and body kinematics, both of which are important determinants of power generation and aerodynamic drag.

Effects of Lateral Shoe Wedges and Toe-in Foot Progression Angles on the Biomechanics of Knee Osteoarthritis during Stationary Cycling

There was a 22% decrease in the knee abduction moment with the 10° wedge but this finding was not accompanied by a decrease in knee adduction angle or subjective pain, and there was an increase in vertical and horizontal PRF which may negate the advantages of the decreased KAM.

Methods to determine saddle height in cycling and implications of changes in saddle height in performance and injury risk: A systematic review

A systematic review of the methods to determine bicycle saddle height and the effects of saddle height on cycling performance and injury risk outcomes found that strong evidence suggests that saddle height should be configured using dynamic measurements of the knee angle, and limb kinematics is influenced by changes in saddle height.


Wedge and orthoses at the FSPI alter kinematics of the lower limb while cycling, although conclusions about their efficacy and response to long-term use are limited.

Saddle Height and Cadence Effects on the Physiological, Perceptual, and Affective Responses of Recreational Cyclists

While cyclists perceived the downward (versus reference) saddle position as greater exercise effort, they also associated it with unpleasant affect, and torque values were higher at lower cadences in all saddle configurations, and the FCC + 20% cadence was associated with faster heart rate, higher RPE, and lower affect compared with FCC and FCC − 20% inall saddle positions.

Influence of Knee Abductor Moment on Patellofemoral Joint Stress and Self-reported Pain of Women with Patellofemoral Pain

Comparing peak, rate of moment development and impulse of KAM and PFJ stress of women with PFP and pain-free controls during stair descent indicates that strategies aimed at decreasing KAM impulse could reduce the load over the PFJ and improve pain of womenwith PFP.

Power output and work in different muscle groups during ergometer cycling

The aim of this study was to calculate the magnitude of the instantaneous muscular power output at the hip, knee and ankle joints during ergometer cycling using a model based upon dynamic mechanics described elsewhere.

Cycling might be a useful exercise in the rehabilitation of patients with injuries to the anterior cruciate ligament, medial collateral ligament of the knee or achilles tendon and an increased pedalling rate increased the muscular activity in most of the muscles investigated, generally without changing the joint load.

The effect of bicycle seat height variation upon oxygen consumption and lower limb kinematics.

The major adaptations to increases in SH are found at the knee and in ankle PF, and the major adaptations in the range of motion (ROM) at the hip, ankle and foot did change.

The effect of prolonged cycling on pedal forces

It would appear that riders became less effective during the recovery phase, which increased the demand for forces during the propulsive phase, and training the pattern of force application to improve effectiveness may a useful strategy to prolong an endurance ride.

Influence of cadence, power output and hypoxia on the joint moment distribution during cycling

The results suggest that the coordinative pattern in cycling is a dominant characteristic of cycling biomechanics and remains robust even in the face of arterial hypoxemia.
