Introduction
I am Senior Lecturer in Sport Coaching at Leeds Beckett University, focusing in the areas of Strength and Conditioning and youth physical development.
I have completed a PhD at Leeds Beckett University examining the implications of leg strength asymmetry in Sub-elite Rugby League players.
My research interests include the development of effective strength and conditioning practices for children, injury reduction through increased athleticism and the development of unilateral leg strength.

This study compared a percentage based approach to resistance training with a 15% velocity loss threshold approach.
The intervention took place during the in season period from January to April and used the Output sports devices and app to deliver the intervention and feedback to all participants.
The slides also include a QR code link to a video...
This presentation outlines some of the key principles and challenges facing British Powerlifting in developing younger powerlifters, with some practical advice for coaches.

Leg strength and multidirectional speed qualities have repeatedly been linked with increased performance during Rugby League (RL) match play and associated with career attainment. However, very little of this evidence for strength has been gained through unliteral measurements with no study available that has examined the impact of strength asymmet...
This presentation explored some underpinning concepts about how youth sport injuries may be both created and prevented, through more effective coaching session planning.
Objectives:
The aim of this study was to analyse the relationship between unilateral leg strength, associated asymmetries and the injuries suffered by sub-elite Rugby League (RL) players in one competitive season.
Design:
A prospective cohort design was used.
Method:
Unilateral leg strength was measured using the rear foot elevated split squat...
During recent years a growing body of research has emerged exploring the asymmetries in performance between limbs, across a range of athletic groups. This research has considered the measurement, calculation, and subsequent effects of asymmetries on groups on sporting populations. However, from this body of work gaps are still evident, in respect t...
ABSTRACT
Objective
The aim of this review was to synthesize the current understanding relating to the risks of lower body functional asymmetry with injury in athletic populations.
Methods:
An iterative data mining and sampling approach was used to construct a search phrase from key words, which were used to identify studies within SPORTdiscus, Me...
The purpose of the study was to determine the unilateral nature of the rear foot elevated split squat (RFESS). Specifically, the production of force by the rear leg was examined to better understand its role, if any, toward successful completion of the exercise. Male volunteers were recruited, (n = 26, age = 23.8 ±4.6 years, mass = 88.1 8 ±10.7kg,...
The rear foot elevated split squat (RFESS) is a multi-joint, unilateral resistance exercise, commonly used in strength and conditioning. No study, to date, has yet analysed the kinetic and kinematic parameters of a multi-repetition maximum leg strength exercise. The aim of this study was to firstly quantify the kinetic and kinematic characteristics...
Methods Rugby league players (n = 50), recruited from three different clubs, were used to investigate the physiological differences in unilateral leg strength and speed, both linear and COD. Tests of unilateral leg strength (rear foot elevated split squat 5RM, Helme et al, ePUB) and speed (20m sprint, modified 5-0-5 test) were separated by 48 hours...
The purpose of this study was to examine the validity and reliability of the Rear Foot Elevated Split Squat (RFESS) five repetition maximum (5RM) test as a field method for measuring unilateral leg strength symmetry. As a validated method of testing symmetry, the RFESS 5RM may be used by Strength and Conditioning coaches and sports medicine staff t...
This poster analyses the kinetic and kinematic characteristics of the rear foot elevated split squat, including intra-set variations and relative force contributions of the rear and front foot.
This was an oral presentation at the 15th Annual conference of the UKSCA. I discussed the correlation between unilateral leg strength, measured by the Rear foot elevated squat 5RM, and both 20m linear sprint and Modified 5-0-5 change of direction test, in Rugby League players.
The purpose of this study was to examine the Rear foot elevated split squat (RFESS) five repetition maximum test as a valid and reliable field method for measuring unilateral leg strength symmetry. With institutional ethical approval, 26 subjects (age = 23.8 ±4.6 years, mass = 88.1 ±10.7kg, height = 1.79±0.1m) with a minimum two years strength and...
The rear foot elevated split squat has been investigated as a method of unilateral leg strength (McCurdy et al., 2004) and subsequent asymmetry. In previous literature, leg strength asymmetry has been investigated in a laboratory using force platform technology (Dos'Santos et al., 2016) or Isokinetic Dynamometry (Jones and Bampouras, 2010). However...
