Effect of resistance training regimens on treadmill running and neuromuscular performance in recreational endurance runners

The purpose of this study was to assess the effects of heavy resistance, explosive resistance, and muscle endurance training on neuromuscular, endurance, and high-intensity running performance in recreational endurance runners. Twenty-seven male runners were divided into one of three groups: heavy resistance, explosive resistance or muscle endurance training. After 6 weeks of preparatory training, the groups underwent an 8-week resistance training programme as a supplement to endurance training. Before and after the 8-week training period, maximal strength (one-repetition maximum), electromyographic activity of the leg extensors, countermovement jump height, maximal speed in the maximal anaerobic running test, maximal endurance performance, maximal oxygen uptake ([V·]O(?max)), and running economy were assessed. Maximal strength improved in the heavy (P = 0.034, effect size ES = 0.38) and explosive resistance training groups (P = 0.003, ES = 0.67) with increases in leg muscle activation (heavy: P = 0.032, ES = 0.38; explosive: P = 0.002, ES = 0.77). Only the heavy resistance training group improved maximal running speed in the maximal anaerobic running test (P = 0.012, ES = 0.52) and jump height (P = 0.006, ES = 0.59). Maximal endurance running performance was improved in all groups (heavy: P = 0.005, ES = 0.56; explosive: P = 0.034, ES = 0.39; muscle endurance: P = 0.001, ES = 0.94), with small though not statistically significant improvements in [V·]O(?max) (heavy: ES = 0.08; explosive: ES = 0.29; muscle endurance: ES = 0.65) and running economy (ES in all groups < 0.08). All three modes of strength training used concurrently with endurance training were effective in improving treadmill running endurance performance. However, both heavy and explosive strength training were beneficial in improving neuromuscular characteristics, and heavy resistance training in particular contributed to improvements in high-intensity running characteristics. Thus, endurance runners should include heavy resistance training in their training programmes to enhance endurance performance, such as improving sprinting ability at the end of a race.

Personal health information in Canada: A comparison of citizen expectations and legislation

This paper explores whether the Canadian legislative protections in place to safeguard medical privacy meet the expectations of Canadians. An overview of current governance systems designed to protect the privacy of personal health information at both the federal and provincial levels is first presented. This is followed by an empirical analysis of the results of a public opinion survey conducted to determine Canadian attitudes about medical privacy, particularly genetic privacy. The analysis highlights areas where legislation and public opinion converge and diverge.

Evaluating the effectiveness of relevance feedback based on a user simulation model: effects of a user scenario on cumulated gain value

We propose a method for performing evaluation of relevance feedback based on simulating real users. The user simulation applies a model defining the user’s relevance threshold to accept individual documents as feedback in a graded relevance environment; user’s patience to browse the initial list of retrieved documents; and his/her effort in providing the feedback. We evaluate the result by using cumulated gain-based evaluation together with freezing all documents seen by the user in order to simulate the point of view of a user who is browsing the documents during the retrieval process. We demonstrate the method by performing a simulation in the laboratory setting and present the “branching” curve sets characteristic for the presented evaluation method. Both the average and topic-by-topic results indicate that if the freezing approach is adopted, giving feedback of mixed quality makes sense for various usage scenarios even though the modeled users prefer finding especially the most relevant documents.     

Adult Questions and Children's Responses: Coordination of perspectives in studies of children's theories of other minds

The main aim of this study is to shed light on the issue of how children learn to identify what is meant by what is said in communicative practices. The study replicates and extends the well-known work on what is referred to as children's 'theories of other minds'. The focus in the present study is on the interplay between the adult and the child, the nature of the task and the child's position in the communicative encounter. Rather than assuming that children have or do not have 'theories of other minds', we explore the communicative conditions under which children can be made sensitive to the nature of other people's (mistaken) beliefs. The empirical work was carried out amongst children aged three to five, since this is the critical age at which it is claimed that children become sensitive to the fact that other people's perspectives of a situation may differ from their own. The results show that whether or not children 'are able' to adopt other people's perspectives is very much a situated affair and reflects the manner in which they are brought into a position where they can share the framing of the adult. The questions posed are interpreted differently by the children in ways that go beyond the intended difference that concerns perspectivity. The test situation is polysemous in many respects and the variation in responses cannot be reduced to such a simple distinction as the one implied in the theory of mind research paradigm, which represents a monological conception of communication.

Parents’ Participation in Their Child’s Schooling

The present study set out to survey Finnish parents’ participation in their child’s schooling and related experiences. The subjects were a nationally representative group of academically and vocationally educated fathers and mothers (N = 391) who had a child on the fifth grade. A great majority of the parents reported that they attended the parent evenings and saw them in a positive light. Most parents helped their child in her/his schoolwork, though some of them were doubtful of their own competence for it. The choice of schools, which was considered mainly by urban parents and academically educated parents, seemed to introduce a new private element into parental participation without changing the existing communal forms of participation.
