Kinematic, Neuromuscular and Bicep Femoris In Vivo Mechanics during the Nordic Hamstring Exercise and Variations of the Nordic Hamstring Exercise (2024)
Journal Article
Ripley, N., Fahey, J., Comfort, P., & McMahon, J. (2024). Kinematic, Neuromuscular and Bicep Femoris In Vivo Mechanics during the Nordic Hamstring Exercise and Variations of the Nordic Hamstring Exercise. #Journal not on list, 3(3), 310-322. https://doi.org/10.3390/muscles3030027

The Nordic hamstring exercise (NHE) is effective at decreasing hamstring strain injury risk. Limited information is available on the in vivo mechanics of the bicep femoris long head (BFLH) during the NHE. Therefore, the purpose of this study was to o...

Journal Article
Soriano, M. A., Jiménez-Ormeño, E., Lake, J. P., McMahon, J. J., Gallo-Salazar, C., Mundy, P., & Comfort, P. (2024). Kinetics and Kinematics of the Push Press, Push Jerk, and Split Jerk. Journal of Strength and Conditioning Research, 38(8), 1359-1365. https://doi.org/10.1519/JSC.0000000000004810

The aim of this study was to explore the kinetics and kinematics across incremental loads with the push press (PP), push jerk (PJ), and split jerk (SJ). Eighteen resistance- trained men performed the 1 repetition maximum (1RM) tests (visit 1) 3–7 day... Read More about Kinetics and Kinematics of the Push Press, Push Jerk, and Split Jerk..

The Effect of Training Modalities on Bicep Femoris Fascicle Length Adaptations: A Systematic Review and Meta-analyses (2024)
Journal Article
Ripley, N., Ross, S., Cuthbert, M., Comfort, P., & McMahon, J. (in press). The Effect of Training Modalities on Bicep Femoris Fascicle Length Adaptations: A Systematic Review and Meta-analyses. #Journal not on list, 1, 1-19. https://doi.org/10.47206/ijsc.v4i1.291

Bicep femoris long head (BFLH) fascicle length (FL) is a modifiable risk factor of hamstring strain injury (HSI) and is extremely adaptable to imposed demands. The aim was to conduct a systematic review and meta-analysis to estimate the effects of di...

Things to keep in mind when selecting physical assessments in youth soccer: Correlations between test performances, interlimb asymmetries, and effects of maturation (2024)
Journal Article
Robles-Palazón, F. J., McMahon, J. J., Ayala, F., & Comfort, P. (2024). Things to keep in mind when selecting physical assessments in youth soccer: Correlations between test performances, interlimb asymmetries, and effects of maturation. PLoS ONE, 19(6), e0305570. https://doi.org/10.1371/journal.pone.0305570

A range of field-based tests have been proposed for inclusion in physical performance assessment batteries. However, there are obvious time and human resources constraints in applied settings. The knowledge of potential relationships between tests on...

Measuring the bicep femoris long head fascicle length via the use of diagnostic ultrasound has become common practice within elite sport, using single images of between 4 and 6 cm. No study to date has compared single image estimations in terms of th... Read More about Comparison between Short, Medium, and Long Fields of View in Estimating Bicep Femoris Fascicle Length.

Effect of Sampling Frequency on a Unilateral Isometric Hamstring Strength Assessment Using Force Plates (2024)
Journal Article

The purpose of this study was to determine the effect of sampling frequency on the 90-90 (90-degrees hip and knee flexion) isometric hamstring assessment. Thirty-three elite female soccer players (age: 18.7 ± 3.7 years; height: 158.3 ± 5.9 cm; body m...

Relative strength explains the differences in multi-joint rapid force production between sexes (2024)
Journal Article
Comfort, P., McMahon, J. J., Lake, J. P., Ripley, N. J., Triplett, N. T., & Haff, G. G. (in press). Relative strength explains the differences in multi-joint rapid force production between sexes. PloS one, 19(2), e0296877. https://doi.org/10.1371/journal.pone.0296877

The primary aim of this study was to determine whether relative strength explains the differences in the rapid force production (force developed during first 150-, 200-, and 250 ms) of females and males, and to evaluate the relationships between peak...
