The aim of this study was to evaluate time dependent changes in 3 dimensional (3D) thorax and pelvis kinematics during an intense 60 min bike ride. 10 experienced male road cyclists pedalled for 60 min at workloads based on previous onset of blood lactate accumulation (OBLA) testing. The 60 min cycle was divided into six 10 min periods consisting of 8 min of steady state cycling (88% of OBLA) followed by 90 s at 140% of OBLA and a 30 s recovery phase (60% of OBLA). Thorax and pelvis kinematic…

Three-dimensional kinematics of competitive and recreational cyclists across different workloads during cycling

No workload effects were found in segment angles but differences, although small, existed when comparing competitive road to recreational cyclists, and when conducting assessment of joint and segment motions.

Changes in the Trunk and Lower Extremity Kinematics Due to Fatigue Can Predispose to Chronic Injuries in Cycling

A 3D kinematic analysis of pedaling technique in a stable power fatigue protocol aimed at establishing relationships between fatigue and postural change and found some of the changes produced could lead to chronic knee and lumbar injuries.

Cycling kinematics in healthy adults for musculoskeletal rehabilitation guidance

The kinematic results support the view that cycling is highly beneficial for comprehensive musculoskeletal rehabilitation and might help clinicians set a target of recovery ROM based on healthy and non-elite individuals and issue suitable guidelines to patients.

Assessment of Three-Dimensional Trunk Kinematics and Muscle Activation during Cycling with Independent Cranks.

T trunk kinematics and surface electromyography during IC and normal crank (NC) cycling during a graded exercise test to volitional fatigue are evaluated and proposed as a potentially beneficial training tool to increase training diversity.

Sensitivity of cycling Motion Performance Indicators (MPIs) to incremented load and their relationship with performance in professional cyclists

There is a lack of research assessing Motion Performance Indicators (MPIs), which have been recently made commercially available. Therefore, this study explored: (1) the influence of incremented

Cycling: joint kinematics and muscle activity during differing intensities.

Assessment of changes in lower limb EMG magnitudes and full body 3D kinematics of 17 well-trained cyclists at three different exercise intensities will guide clinicians in strengthening specific muscles at specific ranges of the cycling pedal revolution.

Effects of cycling on the morphology and spinal posture in professional and recreational cyclists: a systematic review.

The practice of cycling produces adaptations in the morphology of the spine of the cyclist compared to non-cyclists, such as an increase in pelvic tilt and a greater capacity for lumbar flexion in trunk flexion positions, and agreat thoracic kyphosis in the standing position.

Effect of incremental intensities on the spinal morphology and core muscle activation in competitive cyclists.

As the intensity of effort in cycling increases, cyclists significantly increase the thoracic and lumbar spine flexion, the sacral inclination in the sagittal plane, the thoracean spine flexions in the frontal plane, trunk rotation in the transverse plane, as well as the activation of the core muscles.

Effect of cycling exercise on lumbopelvic control performance in elite female cyclists

The OCTOcore application demonstrated that it was a tool in detecting changes in lumbopelvic behavior in the elite female cyclists and it could easily be used by the cyclists themselves.

Effect of bike-fit in the perception of comfort, fatigue and pain

Upright trunk was found to be the most comfortable position for recreational cyclists, where aerodynamics is not so important and Cyclists’ bike perceptions should be taken into account when it comes to choosing the most beneficial position.

Changes in Muscle Activity and Kinematics of Highly Trained Cyclists During Fatigue

There is a direct link between changes in muscle fatigue state and subsequent changes in movement kinematics during cycling, and this study quantified how both localized muscle fatigue and movement k Cinema change over time during exhaustive cycling.

Is Activation of the Back Muscles Impaired by Creep or Muscle Fatigue?

Prolonged spinal flexion can impair sensorimotor control mechanisms and reduce back muscle protection of the underlying spine, due to time-dependent “creep” in soft tissues rather than muscle fatigue.
