Cricket Spin Bowling Tips Pdf 21



In professional cricket, the Laws of Cricket are often modified by a playing regulation that any ball over head height is a Wide ball, but a second fast ball above shoulder height in an over is a no-ball, e.g. in International T20 Cricket[6] and IPLT20.[7] But in International One-Day Cricket[8] and in Test Cricket,[9] two fast pitched short balls per over may pass over shoulder height before no-ball is called, and again any ball over head height is a Wide. Thus competition rules may both tone down the definition of 'dangerous and unfair' (a Wide is a lesser sanction than a no-ball, and cannot be applied if the batter hits, or is hit by, the delivery) and put definite limits on repetition, intended not only to protect the batter but also to maintain a fair contest between bat and ball, preventing such bowling being used to limit the batter's ability to score. There is presently some difference of opinion between the authorities that is evident in the differences between Law and regulation.

When a no-ball is bowled, runs are awarded to the batting team. In Test cricket, One Day International cricket and T20 International cricket, the award is one run; in some domestic competitions, particularly one-day cricket competitions, the award is two runs. All such runs are scored as extras and are added to the batting team's total, but are not credited to the batter. For scoring, no-balls are considered to be the fault of the bowler (even if the infringement was committed by a fielder), and are recorded against the bowler's record in their bowling analysis.


The 1835 code legitimised roundarm bowling, and prevented overarm bowling by penalty of no-ball (see also 1835 English cricket season). The previous Laws did not disbar either, but had been interpreted variously by umpires reflecting custom and practice, at some cost to the careers of the bowling innovators. Further changes were made in 1845, and in 1864 bowlers were finally free to bowl overarm, enshrined in the pithy phrase "The ball must be bowled."


Bowling in cricket is a complex sporting movement which, despite being well characterised, still produces a significant number of injuries each year. Fast bowlers are more likely to be injured than any other playing role. Frequency, duration, intensity and volume of bowling, which have been generalised as measurements of workload, are thought to be risk factors for injuries. Injury rates of fast bowlers have not reduced in recent years despite the implementation of various workload monitoring practices.


The use of mainly frequency and time-based measures to manage bowling programmes is common, with bowling guidelines established from grassroot to elite levels of cricket [61]. The strictest guidelines are applied to underage groups where research has demonstrated that players are at greatest risk of developing lumbar spine injuries mainly due to physiological immaturity [13, 25, 30, 32, 62]. However, the incidence and prevalence of lumbar spine injuries in bowlers, across all age groups, has not significantly improved since the implementation of these guidelines [4].


Neither risk of bias or quality of evidence assessment were conducted as the purpose of this review was not to summarize the findings of included studies or how bias may be introduced into the results of these studies. The purpose was to primarily summarize the methods used to quantify frequency, intensity, time and volume of bowling in cricket-based studies rather than critique the reported results.


It is well-established that cricket fast bowlers carry the largest physical demand in cricket and are subject to a greater injury risk than other players [4]. Considering this, we systematically searched the literature related to cricket bowling and synthesised information related to the variables of frequency, time, intensity and volume used to monitor bowling.


HR and BL were used to quantify physiological response to bowling [39, 47, 48, 56] or fatigue [31, 45, 46] and although it is common for these variables to be used as measures of exercise intensity, it is more accurate to classify them as physiological responses to effort [74, 75]. Further, HR and BL can be impacted by many varied factors, including: exercise training history [76], body mass [77], ambient temperature [78], stress [79], or composition of the playing surface [80]. Therefore, neither are generalisable between bowlers and so are less appropriate as a means of constructing volume-based bowling programmes. Volume, when derived using an appropriate measurement of force (i.e., product of force, frequency and duration), is likely to offer a suitable method to monitor and prescribe training with respect to injury management. However, the current methods used to measure external forces during cricket bowling are limited to laboratory settings [81], which makes it challenging to include force measurements to quantify the demands of training and matches.


The ACWR is used to monitor changes in demand over time using a dual-threshold approach where both too little, and too great, a demand can increase injury risk [93]. However, some conceptual and statistical concerns have been highlighted in a recent study [94] and contradictions exist in the literature as to the usefulness of the ACWR with respect to injury management. For example, Pote and Christie [13] could not identify a relationship between workload and injury risk whereas Warren et al. [18] concluded that large spikes in workload increased injury risk. Inconsistencies in these findings are likely to be partially explained by differences in how ACWR has been calculated in the studies included in this review, where some authors used variables of frequency and time only [18, 27], while others also used RPE or sRPE [13, 15, 23]) when estimating volumes. While it makes sense to customise the variables used to calculate ACWR between sports, such as triathlon and cricket, inconsistencies in variables within a single sport (e.g., cricket) become problematic when used to inform generalised injury management guidelines. While ACWR does provide knowledge of troughs and peaks in bowling volumes, both of which are believed to increase injury risk in fast bowlers [15, 95], the authors of a recent systematic review [95] concluded that despite some studies supporting its use [13, 15, 18], it is yet to be confirmed as useful in managing injury risk. The authors of a recent review propose that the exponentially-weighted moving average model (EWMA) might be more appropriate for determining overall training demands [96]. This model is weighted more heavily towards recent demands, rather than older demands [97], and could be more suitable for fast bowlers than using the rolling average method for determining ACWR as it accounts for the decreasing effects of fitness and fatigue over time.


Commonly used bowling management tools remain important to help understand the number of repetitions performed as well as some aspects of the physiological and psychological demands. In addition, we support the conclusions of other authors [18] who advocate the individualisation of training programmes to provide better outcomes with respect to performance and injury management. There is a need for the inclusion of valid and reliable methods to measure intensity during bowling to quantify training volume and to minimize the risk of injury. We suggest that objective measurements of external force, implementable during training and match play, offer the most promise. One method for deriving forces in this context might be through using inertial measurement units, as described in previous studies on cricket [52, 98]. Callaghan et al. [98] attempted to investigate the use of accelerometers to estimate bowling intensity but suggested that the relationship between segmental accelerometer-derived force curves and GRF experienced during front foot contact was more complex than hypothesised. Therefore, before such a method can be implemented, further validation research is required.


While elite cohorts have been most often studied, the potential exists to develop monitoring tools that can be used with non-elite bowlers. Currently, it is less likely that sub-elite and grassroot cohorts have access to the technical or other resources necessary to consistently and effectively measure and monitor bowling demands. Where these cohorts do monitor bowling demands they are limited to using the simple and mainly subjective methods we have identified in this review. There is an opportunity for future research to explore methods for measuring bowling demands that can benefit cricketers of all ages and abilities.


Although 48 studies were included in this systematic review, only thirteen linked FITT-VP variables to injury incidence. Further, the variables used in these studies have several limitations including impacts from environmental factors such as temperature and ground hardness, or hydration levels of participants. Thus, drawing conclusions from these studies is difficult and more research is needed linking bowling volumes to injury. Lastly, although the literature search strategy found significantly more articles than other recent similar systematic reviews in cricket [4, 99, 100] it is acknowledged that it is possible some relevant studies were missed (for example, those not available in English language or those in the grey literature). However, we feel confident that most relevant studies have been identified, and in the inferences drawn from the included studies.


Experience the game-play of arguably one of the purest formats of the game- a format that serves as the base of cricket, but is sadly dying in the limelight of the shortest format. Real Cricket 20 promises true-to-life test match conditions with lively green pitches or the pacers and the rough marks for the spinners to have a go at them. Test match attacking field set-up options add the icing to the cake. Also, experience the surreal experience of playing a Test Match under the lights with the introduction of Pink Ball Test for the first time in mobile cricketing history. 350c69d7ab
