Abstract

Introduction: Match play within professional cricket commences at a variety of times during the day, with the shorter ‘white ball’ formats often starting anywhere from 11:00 to 19:30. This presents large windows of opportunity for pre-competition strategies to be utilised to improve performance. Sal...

This presents large windows of opportunity for pre-competition strategies to be utilised to improve performance. Salivary hormones, in particular testosterone, exhibit a circadian rhythm over the waking day, falling up to &#xF07E;50% to a nadir at &#xF07E;20:00. With salivary testosterone concentrations showing strong links with neuromuscular, cognitive and motivational benefits, the ability to optimise those natural levels could be a way to improve an athlete&#x2019;s match day performance. Engaging in a bout of exercise prior to competition has been used by sports teams to prime the body, with the purpose to enhance performance. Methods: In this study, a group of 21 professional male cricket players (aged: 26 &#xF0B1; 6 years, body mass: 88.1 &#xF0B1; 4.4 kg, height: 184 &#xF0B1; 3.6 cm) engaged in an investigation with the aim to compare the effects of 2 morning priming protocols on markers of afternoon performance. Following a randomised-counterbalance design, the players were split into groups of 4. The control day consisted of the players reporting for the afternoon tests (Readiness To Perform questionnaire [RTP], Stroop Test, countermovement jump [CMJ] and Run-two sprint at &#xF07E; 15:00, with 30min slots for each group. The experimental trials consisted of groups arriving at &#xF07E; 9:00 with 30min slots, to engage in either the Trap bar deadlift protocol (4 reps at 50%, 70%, 80%, 3 x 4 at 85% 1RM) or repeated Sprint session (6 x 35.4m with a 180&#xF0B0; turn at the midpoint) with a 30s recovery, roles were reversed following a 7-day break; participants then rested for &#xF07E;5h and returned to completed the afternoon performance tests. Results: Run-two sprint time was significantly reduced (p &lt; 0.001) (CON = 5.99 &#xF0B1; 0.17s, Sprint = 5.94 &#xF0B1; 0.17s, Trap bar = 5.91 &#xF0B1; 0.17s), Trap bar saw further reductions when compared to the Sprint (p = 0.032). Only the Trap bar protocol saw a significant increase in CMJ Jump height (JH) (p = 0.021) (CON = 43.8 &#xF0B1; 6.8cm, Sprint = 45.0 &#xF0B1; 7.3cm, Trap bar = 45.2 &#xF0B1; 6.5cm). There was no significant correlation between absolute (p &gt; 0.05) or relative strength (p &gt; 0.05) and the effectiveness of the priming strategies on neuromuscular performance. Both Sprint and Trap bar expressed significant reductions in time to complete the Stroop test (p &lt; 0.05) (CON &#x2013; 51.1 &#xF0B1; 4.7s, Sprint &#x2013; 48.4 &#xF0B1; 3.6s, Trap bar &#x2013; 47.9 &#xF0B1; 2.8s), with Trap bar again reporting further reductions compared to Sprint (p &lt; 0.05). Whilst the trials demonstrated a significant impact on the athletes&#x2019; afternoon neuromuscular and cognitive performance, their readiness to perform scores were unaffected (p &gt; 0.05). Conclusion: Performing morning exercise is associated with afternoon neuromuscular and cognitive performance benefits, with no detriment to the readiness to perform.</abstract><type>E-Thesis</type><journal/><volume/><journalNumber/><paginationStart/><paginationEnd/><publisher/><placeOfPublication>Swansea</placeOfPublication><isbnPrint/><isbnElectronic/><issnPrint/><issnElectronic/><keywords/><publishedDay>23</publishedDay><publishedMonth>2</publishedMonth><publishedYear>2022</publishedYear><publishedDate>2022-02-23</publishedDate><doi/><url/><notes>A selection of third party content is redacted or is partially redacted from this thesis due to copyright restrictions.</notes><college>COLLEGE NANME</college><CollegeCode>COLLEGE CODE</CollegeCode><institution>Swansea University</institution><supervisor>Kilduff, Liam</supervisor><degreelevel>Master of Research</degreelevel><degreename>MSc by Research</degreename><apcterm/><lastEdited>2022-02-23T12:59:32.1625500</lastEdited><Created>2022-02-23T12:31:24.4242529</Created><path><level id="1">Faculty of Science and Engineering</level><level id="2">School of Engineering and Applied Sciences - Uncategorised</level></path><authors><author><firstname>FERGUS</firstname><surname>NUTT</surname><order>1</order></author></authors><documents><document><filename>59443__22436__f1ff891f12d649ea92c63027ab6f7474.pdf</filename><originalFilename>Nutt_Fergus_MSc_Research_Thesis_Final_Redacted.pdf</originalFilename><uploaded>2022-02-23T12:56:55.6219757</uploaded><type>Output</type><contentLength>2293448</contentLength><contentType>application/pdf</contentType><version>Redacted version - open access</version><cronfaStatus>true</cronfaStatus><documentNotes>Copyright: The author, Fergus Nutt, 2022.</documentNotes><copyrightCorrect>true</copyrightCorrect><language>eng</language></document></documents><OutputDurs/></rfc1807>
