In-season competition and tournaments for team sports can be both long and congested, with some sports competing up to three times per week. During these periods of time, athletes need to prepare technically, tactically and physically for the next fi...

Electromyographical Differences Between the Hyperextension and Reverse-Hyperextension (2021)
Journal Article
Cuthbert, M., Ripley, N. J., Suchomel, T. J., Alejo, R., McMahon, J. J., & Comfort, P. (2021). Electromyographical Differences Between the Hyperextension and Reverse-Hyperextension. Journal of Strength and Conditioning Research, 35(6), 1477-1483. https://doi.org/10.1519/jsc.0000000000004049

The aims of this study were to compare muscle activation of the erector spinae (ES), gluteus maximus (GMax), and biceps femoris (BF) during the hyperextension (HE) and reverse-HE (RHE) exercises. Ten subjects (age, 23 ± 4 years; height, 175.9 ± 6.9 c... Read More about Electromyographical Differences Between the Hyperextension and Reverse-Hyperextension.

Comparing the effects of plyometric and isometric strength training on dynamic and isometric force-time characteristics (2021)
Journal Article
Lum, D., Comfort, P., M. Barbosa, T., & Balasekaran, G. (2022). Comparing the effects of plyometric and isometric strength training on dynamic and isometric force-time characteristics. Biology of Sport, 39(1), 189-197. https://doi.org/10.5114/BIOLSPORT.2022.103575

The purpose of the study was to compare the change in dynamic and isometric force-time characteristics after plyometric (PLYO) or isometric strength training (ISO). Twenty-two endurance runners (age = 37 ± 6 years,stature = 1.71 ± 0.05 m, body mass...

Biomechanical determinants of performance and injury risk during cutting : a performance-injury conflict? (2021)
Journal Article
Dos'Santos, T., Thomas, C., McBurnie, A., Comfort, P., & Jones, P. (2021). Biomechanical determinants of performance and injury risk during cutting : a performance-injury conflict?. Sports Medicine, 51(9), 1983-1998. https://doi.org/10.1007/s40279-021-01448-3

Most cutting biomechanical studies investigate performance and knee joint load determinants independently. This is surprising because cutting is an important action linked to performance and non-contact anterior cruciate ligament (ACL) injuries. The...

Unilateral vs. bilateral hamstring strength assessments : comparing reliability and inter-limb asymmetries in female soccer players. Journal of Sports Sciences, 39(13), 1481-1488. https://doi.org/10.1080/02640414.2021.1880180

The aims in the present study were to assess reliability for two unilateral and two bilateral field-based hamstring assessments and compare magnitude, direction and agreement of inter-limb asymmetry between tests and sessions. Twenty-nine female socc... Read More about Unilateral vs. bilateral hamstring strength assessments : comparing reliability and inter-limb asymmetries in female soccer players.

Modifiable risk factors of hamstring strain injury : assessment, performance and training (2021)
Thesis
Ripley, N. Modifiable risk factors of hamstring strain injury : assessment, performance and training. (Thesis). University of Salford

Hamstring strain injuries (HSIs), which are typically sustained during high velocity movements (i.e., sprinting or high velocity running), commonly involves the bicep femoris long head (BFLH). To date, the Nordic hamstring exercise (NHE) is the most... Read More about Modifiable risk factors of hamstring strain injury : assessment, performance and training.
