We, ourselves and us: Tensions of identity, intersubjectivity and positionality stemming from the people and dancefloors project.

Grounded in intersubjective participatory action research, the people and dancefloors project has sought to produce a space for the co-creation of knowledge about dancefloors and drug taking, building a platform for developing insights from the positionality of current drug users. Through film, it provides hermeneutic insight while legitimising their voices. In this paper, we share some reflections as researchers/users/activists arising from our involvement in the project.

Foot structure and knee joint kinetics during walking with and without wedged footwear insoles.

The relationship between static foot structure characteristics and knee joint biomechanics during walking, or the biomechanical response to wedged insoles are currently unknown. In this study, 3D foot scanning, dual X-ray absorptiometry and gait analysis methods were used to determine structural parameters of the foot and assess their relation to knee joint loading and biomechanical response to wedged insoles in 30 patients with knee osteoarthritis. In multiple linear regression models, foot fat content, height of the medial longitudinal arch and static hind foot angle were not associated with the magnitude of the knee adduction moment (R = 0.

Is There an Optimal Pole Length for Double Poling in Cross Country Skiing?

The aim of this study was to determine the effects of pole length on energy cost and kinematics in cross country double poling. Seven sub-elite male athletes were tested using pole sets of different lengths (ranging between 77% and 98% of participants' body height). Tests were conducted on a treadmill, set to a 2% incline and an approximate racing speed.

Quadrupedal Locomotion-Respiration Entrainment and Metabolic Economy in Cross-Country Skiers.

A 1:1 locomotion-respiration entrainment is observed in galloping quadrupeds, and is thought to improve running economy. However, this has not been tested directly in animals, as animals cannot voluntarily disrupt this entrainment. The purpose of this study was to evaluate metabolic economy in a human gait involving all four limbs, cross-country skiing, in natural entrainment and forced nonentrainment.
