The Influence of Performance Level, Age and Gender on Pacing Strategy During a 100-km Ultramarathon

The aim of this study is to analyse the influence of performance level, age and gender on pacing during a 100-km ultramarathon. Results of a 100-km race incorporating the World Masters Championships were used to identify differences in relative speeds in each 10-km segment between participants finishing in the first, second, third and fourth quartiles of overall positions (Groups 1, 2, 3 and 4, respectively). Similar analyses were performed between the top and bottom 50% of finishers in each age category, as well as within male and female categories. Pacing varied between athletes achieving different absolute performance levels. Group 1 ran at significantly lower relative speeds than all other groups in the first three 10-km segments (all P < 0.01), and significantly higher relative speeds than Group 4 in the 6th and 10th (both P < 0.01), and Group 2 in the 8th (P = 0.04). Group 4 displayed significantly higher relative speeds than Group 2 and 3 in the first three segments (all P < 0.01). Overall strategies remained consistent across age categories, although a similar phenomenon was observed within each category whereby ‘top’ competitors displayed lower relative speeds than ‘bottom’ competitors in the early stages, but higher relative speeds in the later stages. Females showed lower relative starting speeds and higher finishing speeds than males. ‘Top’ and ‘bottom’ finishing males displayed differing strategies, but this was not the case within females. Although pacing remained consistent across age categories, it differed with level of performance within each, possibly suggesting strategies are anchored on direct competitors. Strategy differs between genders and differs depending on performance level achieved in males but not females.

Public Protection? The Implication of Grayling's 'Transforming Rehabilitation' Agenda on the Safety of Women and Children

Abstract The Coalition Government's new Transforming Rehabilitation (TR) agenda jeopardises the work undertaken with perpetrators of domestic abuse by highly skilled, qualified probation staff. Under new changes outlined by Grayling, Lord Chancellor and Secretary of State for Justice, probation clients who are assessed as posing a medium/low risk of causing harm will be assigned to private sector/voluntary organisations rather than come under the remit of the National Probation Service. This article argues that victims of domestic abuse, primarily women and children, will be placed at an increased risk of harm given this latest TR strategy. The majority of domestic abuse cases will be assessed as posing a medium risk of causing harm and will receive lower levels of intervention by a variety of disparate agencies and organisations. The Ministry of Justice states that the National Probation Service will directly manage offenders who pose a high risk of serious harm to the public, this article will argue that all perpetrators of domestic abuse should be considered as an important exception to this stance, and should remain under the auspices of Probation supervision, irrespective of statistical risk assessment, as has sex offender case management and sex offender treatment programme delivery.
