Practical cooling manoeuvres during simulated soccer in the heat

A thesis submitted to the University of Bedfordshire, in partial fulfilment of the requirements for the degree of Master of Science by Research.The globalisation of soccer match-play has meant that major international and domestic competitions typically occur in hot environments with ambient temperature exceeding 28°C (Taylor and Rollo, 2014). Previous simulated (Aldous et al., 2016) and soccer match-play data (Mohr et al., 2012) in the heat (30 - 43°C) have reported significant reductions in physical performance measures when compared to a temperate environment (18 - 21°C). Practical strategies to reduce these heat-mediated decrements in physical performance whilst fitting in with the time constraints practitioners are faced with in soccer are warranted (Taylor and Rollo, 2014; Russel et al., 2015). Therefore, the aim of the present investigation is to examine the efficacy of practical cooling manoeuvres which can be actively worn during a pre-match warmup and whilst conducting general changing room preparatory tasks (downtime prior to kick off and half-time) on simulated soccer performance in a hot environment (32°C and 60% rH; WBGT: 28°C). Seven male university level soccer-players completed one Yo-Yo Intermittent Recovery Test level 1, two familiarization sessions, one peak speed assessment and four randomized, counterbalanced experimental trials of the intermittent Soccer Performance Test (iSPT) at 32°C. Four experimental trials consisted of cooling during a soccer-specific prematch warm-up (~24 min), downtime prior to kick-off (12 min) and half-time interval (10 min) via (1) Ice Vest (VEST); (2) Neck Cooling (NECK); (3) VEST and NECK (VEST+NECK) used concurrently; or with no-cooling (CON). Physical performance [total distance (TD), highspeed distance (HSD), sprint distance, variable run distance (VRD) and low-speed distance (LSD) covered], body temperatures [rectal temperature (Tre), mean skin temperature (Tsk) and neck temperature (neckTsk)], physiological [heart-rate (HR) and change in body-mass] and perceptual response [rate of perceived exertion (RPE), thermal comfort (TC), thermal sensation (TS) and neck thermal sensation (TSneck)] were all measured. When compared to CON, sprint distance covered was significantly improved (P < 0.05) during the first and last 15 min in NECK, final 15 min in VEST, and final 30 min in VEST+NECK during iSPT, respectively. In xvi VEST, Tsk was significantly reduced (P < 0.05) until 15 min of iSPT compared to CON. In NECK and VEST+NECK, TSneck and neckTsk were significantly reduced (P < 0.01) prior to the start of iSPT with neckTsk also significantly lower post half-time cooling, compared to CON. Furthermore, VEST+NECK also significantly reduced (P < 0.05) TS prior to the start of iSPT, compared to CON. No further significance (P > 0.05) was observed for physical performance, physiological or perceptual responses during iSPT for all conditions. Pre- and half-time cooling via VEST+NECK was most ergogenic and significantly improved sprint performance during the final 30 min of iSPT in 32°C, important given the prominence of sprinting prior to goals and assists during soccer match-play (Faude et al., 2012). Further research with a larger sample size is warranted to further elucidate the mechanisms for the enhanced performance

A Statistical Investigation into Factors Affecting Results of One Day International Cricket Matches

The effect of playing “home” or “away” and many other factors, such as batting first or second, winning or losing the toss, have been hypothesised as influencing the outcome of major cricket matches. Anecdotally, it has often been noted that Subcontinental sides (India, Pakistan, Sri Lanka and Bangladesh) tend to perform much better on the Subcontinent than away from it, whilst England do better in Australia during cooler, damper Australian Summers than during hotter, drier ones. In this paper, focusing on results of men’s One Day International (ODI) matches involving England, we investigate the extent to which a number of factors – including playing home or away (or the continent of the venue), batting or fielding first, winning or losing the toss, the weather conditions during the game, the condition of the pitch, and the strength of each team’s top batting and bowling resources – influence the outcome of matches. By employing a variety of Statistical techniques, we find that the continent of the venue does appear to be a major factor affecting the result, but winning the toss does not. We then use the factors identified as significant in an attempt to build a Binary Logistic Regression Model that will estimate the probability of England winning at various stages of a game. Finally, we use this model to predict the results of some England ODI games not used in training the model

Algorithms for classification of combinatorial objects

A recurrently occurring problem in combinatorics is the need to completely characterize a finite set of finite objects implicitly defined by a set of constraints. For example, one could ask for a list of all possible ways to schedule a football tournament for twelve teams: every team is to play against every other team during an eleven-round tournament, such that every team plays exactly one game in every round. Such a characterization is called a classification for the objects of interest. Classification is typically conducted up to a notion of structural equivalence (isomorphism) between the objects. For example, one can view two tournament schedules as having the same structure if one can be obtained from the other by renaming the teams and reordering the rounds. This thesis examines algorithms for classification of combinatorial objects up to isomorphism. The thesis consists of five articles – each devoted to a specific family of objects – together with a summary surveying related research and emphasizing the underlying common concepts and techniques, such as backtrack search, isomorphism (viewed through group actions), symmetry, isomorph rejection, and computing isomorphism. From an algorithmic viewpoint the focus of the thesis is practical, with interest on algorithms that perform well in practice and yield new classification results; theoretical properties such as the asymptotic resource usage of the algorithms are not considered. The main result of this thesis is a classification of the Steiner triple systems of order 19. The other results obtained include the nonexistence of a resolvable 2-(15, 5, 4) design, a classification of the one-factorizations of k-regular graphs of order 12 for k ≤ 6 and k = 10, 11, a classification of the near-resolutions of 2-(13, 4, 3) designs together with the associated thirteen-player whist tournaments, and a classification of the Steiner triple systems of order 21 with a nontrivial automorphism group.reviewe
