The Role Of Pennation Angle And Architectural Gearing To Rate Of Force Development In Dynamic And Isometric Muscle Contractions, Bas Van Hooren, Per Aagaard, Andrea Monte, Anthony J. Blazevich

Research outputs 2022 to 2026

Background: Associations between muscle architecture and rate of force development (RFD) have been largely studied during fixed-end (isometric) contractions. Fixed-end contractions may, however, limit muscle shape changes and thus alter the relationship between muscle architecture an RFD. Aim: We compared the correlation between muscle architecture and architectural gearing and knee extensor RFD when assessed during dynamic versus fixed-end contractions. Methods: Twenty-two recreationally active male runners performed dynamic knee extensions at constant acceleration (2000°s−2) and isometric contractions at a fixed knee joint angle (fixed-end contractions). Torque, RFD, vastus lateralis muscle thickness, and fascicle dynamics were compared during 0–75 and 75–150 ms …

Exploring The Re-Legitimisation Of Messages For Health And Physical Education Within Contemporary English And Welsh Curricula Reform, J. Stirrup, David Aldous, S. Gray, R. Sandford, O. Hooper, S. Hardley, A. S. Bryant, N. R. Carse

Research outputs 2022 to 2026

This paper explores how messages for health and PE ([H]PE) within English and Welsh curricula are being re-legitimised through distinct performance and competence pedagogic models. Drawing upon Bernstein’s sociology of knowledge (Bernstein, 1996. Pedagogy, symbolic control and identity: Theory, research, critique. Taylor and Francis; 2000. Pedagogy, symbolic control and identity: Theory, research and critique (revised ed.). Rowman and Littlefield) data was generated through a deductive content analysis of the contemporary statutory English National Curriculum for Physical Education (NCPE) and the new Curriculum for Wales (CfW), Health and Well-Being Area of Learning and Experience (HWB-AoLE). Findings illustrate how the current English …

Athlete Experiences Of Communication Strategies In Applied Sports Nutrition And Future Considerations For Mobile App Supportive Solutions, David Mark Dunne, Carmen Lefevre-Lewis, Brian Cunniffe, Samuel George Impey, David Tod, Graeme Leonard Close, James P. Morton, Rebecca Murphy

Research outputs 2022 to 2026

Aim:

This study aimed to explore athletes' experiences and opinions of communication strategies in applied sports nutrition, as well as capture suggestions for future mobile app supportive solutions.

Methods:

A qualitative approach was used for this research. Data was generated from semi-structured focus groups (n = 9) with a purposive sample of 41 (male = 24, female = 17) full time professional athletes (mean age 24 ± 4.59) from five sports (football, rugby union, athletics, cycling, and boxing). Data was analyzed using reflexive thematic analysis.

Results:

The analysis identified four higher order themes and five sub themes. Athletes appear dissatisfied …

Comparing Biomechanical Time Series Data Across Countermovement Shrug Loads, David Meechan, Stuart A. Mcerlain-Naylor, John J. Mcmahon, Timothy J. Suchomel, Paul Comfort

Research outputs 2022 to 2026

The effect of load on time-series data has yet to be investigated during weightlifting derivatives. This study compared the effect of load on the force–time and velocity–time curves during the countermovement shrug (CMS). Twenty-nine males performed the CMS at relative loads of 40 %, 60 %, 80 %, 100 %, 120 %, and 140 % one repetition maximum (1RM) power clean (PC). A force plate measured the vertical ground reaction force (VGRF), which was used to calculate the barbell-lifter system velocity. Time-series data were normalized to 100 % of the movement duration and assessed via statistical parametric mapping (SPM). SPM …
