The strengh model of self-control in sport and exercise psychology

The strength model of self-control assumes that all acts of self-control (e.g., emotion regulation, persistence) are empowered by a single global metaphorical strength that has limited capacity. This strength can become temporarily depleted after a primary self-control act, which, in turn, can impair performance in subsequent acts of self-control. Recently, the assumptions of the strength model of self-control also have been adopted and tested in the field of sport and exercise psychology. The present review paper aims to give an overview of recent developments in self-control research based on the strength model of self-control. Furthermore, recent research on interventions on how to improve and revitalize self-control strength will be presented. Finally, the strength model of self-control has been criticized lately, as well as expanded in scope, so the present paper will also discuss alternative explanations of why previous acts of self-control can lead to impaired performance in sport and exercise.

Exercise augments the effects of cognitive-behavioural therapy in the treatment of binge eating

To evaluate the effects of adding exercise and maintenance to cognitive-behavior therapy (CBT) for binge eating disorder (BED) in obese women. One hundred fourteen obese female binge eaters were randomized into four groups: CBT with exercise and maintenance, CBT with exercise, CBT with maintenance, and CBT only. Eighty-four women completed the 16-month study. Subjects who received CBT with exercise experienced significant reductions in binge eating frequency compared with subjects who received CBT only. The CBT with exercise and maintenance group had a 58% abstinence rate at the end of the study period and an average reduction of 2.2 body mass index (BMI) units (approximately 14 lb). BMI was significantly reduced in the subjects in both the exercise and maintenance conditions. The results suggest that adding exercise to CBT, and extending the duration of treatment, enhances outcome and contributes to reductions in binge eating and BMI.

Effects of acute physical exercise on executive functions: a comparison between aerobic and strength exercise

The aim of this study was to compare the effects of acute aerobic and strength exercises on selected executive functions. A counterbalanced, crossover, randomized trial was performed. Forty-two healthy women were randomly submitted to three different conditions: (1) aerobic exercise, (2) strength exercise, and (3) control condition. Before and after each condition, executive functions were measured by the Stroop Test and the Trail Making Test. Following the aerobic and strength sessions, the time to complete the Stroop "non-color word" and "color word" condition was lower when compared with that of the control session. The performance in the Trail Making Test was unchanged. In conclusion, both acute aerobic and strength exercises improve the executive functions. Nevertheless, this positive effect seems to be task and executive function dependent.

Cognitively engaging chronic physical activity, but not aerobic exercise, affects executive functions in primary school children: A group-randomized controlled trial

Although the positive effects of different kinds of physical activity (PA) on cognitive functioning have already been demonstrated in a variety of studies, the role of cognitive engagement in promoting children’s executive functions is still unclear. The aim of the present study was therefore to investigate the effects of two qualitatively different chronic PA interventions on executive functions in primary school children. 181 children aged between 10 and 12 years were assigned to either a 6-week physical education program with a high level of physical exertion and high cognitive engagement (team games), a physical education program with high physical exertion but low cognitive engagement (aerobic exercise), or to a physical education program with both low physical exertion and low cognitive engagement (control condition). Executive functions (updating, inhibition, shifting) and aerobic fitness (multistage 20-meter shuttle run test) were measured before and after the respective condition. Results revealed that both interventions (team games and aerobic exercise) have a positive impact on children’s aerobic fitness (4-5 % increase in estimated VO2max). Importantly, an improvement in shifting performance was found only in the team games and not in the aerobic exercise or control condition. Thus, the inclusion of cognitive engagement in PA seems to be the most promising type of chronic intervention to enhance executive functions in children, providing further evidence for the importance of the qualitative aspects of PA.

European perspective on sport psychology

This chapter describes the development of sport psychology in Europe. Starting from the early years at the beginning of the 20th century, the contribution of European sport psychology in different cultural traditions to the development of this discipline is highlighted. The foundation of FEPSAC, the European Federation of Sport Psychology, and its role in this development are emphasised. During the first 20 years, Europe was a divided continent and the challenges were to establish a common understanding and possibilities for scientific exchange. After the fall of the Berlin wall and the change of the political landscape in Europe, central aims were to foster scientific exchange despite language difficulties, to develop a common understanding, to help young sport psychologists and to establish sport psychology as a professional field. In the new century, one group of challenges identified refers to unification, for example in education and training, in the services delivery, and in the structure. The second group of challenges relates to diversification, be it in the educational and vocational pathways, the different sports and physical activities, the inclusion of persons with special needs or background, or the publications.

Sport psychology and indigenous performing artists

A group of students from the Aboriginal Centre for the Performing Arts participated in a mental skills training program that focused on goal setting, self-confidence development, and team building. There were 13 two-hour sessions held over a 20-week period. The participants, cultural issues, and the basic structure of the program are described. The author's observations regarding competition, displays of affection, collective values, and the importance of family and nature are provided. The participants qualitatively evaluated the program. Conclusions related to group process, program structure, and diversity are presented. These conclusions should be of value in terms of shaping future group mental skills training programs.
