Barbell hip thrust exercises have risen in popularity within the biomechanics and strength and conditioning literature over recent years, as a method of developing the hip extensor musculature. Biomechanical analysis of the hip thrust beyond electromyography is yet to be conducted. The aim of this study was therefore to perform the first comprehensive biomechanical analysis the barbell hip thrust. Nineteen resistance trained males performed three repetitions of the barbell hip thrust at 70% one-repetition maximum. Kinematic (250 Hz) and kinetic (1000 Hz) data were used to calculate angle, angular velocity, moment and power data at the ankle, knee, hip and pelvic-trunk joint during the lifting phase. Results highlighted that the hip thrust elicits significantly (p < 0.05) greater bilateral extensor demand at the hip joint in comparison with the knee and pelvic-trunk joints, whilst ankle joint kinetics were found to be negligible. Against contemporary belief, hip extensor moments were not found to be consistent throughout the repetition and instead diminished throughout the lifting phase. The current study provides unique insight to joint kinematics and kinetics of the barbell hip thrust, based on a novel approach, that offers a robust evidence base for practitioners to guide exercise selection.

An investigation of the clinical relationship between foot posture and patellofemoral joint alignment Curran, Sarah (Cardiff Metropolitan University, 2008)It has been suggested that abnormal foot posture is related to patellofemoral joint pain. An understanding of the relationship hinges on assessment of the relationship between the two, but whilst satisfactory (reliable and ...
A PILOT STUDY TO ASSESS JOINT HYPERMOBILITY AS A PREDICTOR OF LOWER LIMB INJURY IN BRITISH OFFICER CADETS DURING THE COMMISSIONING COURSE Bennett, Hannah (2014-04)Aim and objectives: The primary aim of this study was to establish whether joint hypermobility can help predict lower limb injury risk in a military population. Objectives were to (i) determine the prevalence of joint ...
Is coffee an effective pre-workout drink? – The effects of ingesting naturalistic doses of caffeine on one-repetition maximum muscular strength and muscular endurance in females. Thomas, Gabrielle (Cardiff Metropolitan University, 2015)Extensive research has been conducted on the ergogenic effects of caffeine for endurance performance yet far fewer studies have investigated the effects for intense, short-term exercise. Particularly lacking in documented ...
