Fit between situational and dispositional goal orientation, and its effects on flow experience and affective well-being during sports.

Flow represents an optimal psychological state that is intrinsically rewarding. However, to date only a few studies have investigated the conditions for flow in sports. The present research aims to expand our understanding of the psychological factors that promote the flow experience in sports, focusing on the person-goal fit, or more precisely on the athletes’ situational and dispositional goal orientations. We hypothesize that a fit between an athlete’s situational and dispositional approach versus avoidance goal orientation should promote flow, whereas a non-fit will hinder flow during sports. In addition to the flow experience, we hypothesize that an athlete’s affective well-being is also affected by the person-goal fit. Here our assumptions are theoretically rooted in research on person-environment fit. An experimental study in an ecologically valid sport setting was conducted in order to draw causal conclusions and derive useful strategies for the practice of sports. Specifically, we investigated 67 male soccer players from a regional amateur league during a regular training session. They were randomly assigned to an approach or avoidance goal group and asked to take five penalty shots. Immediately afterwards, their flow experience and affective well-being during the penalty shootout were measured. As predicted, soccer players with a strong dispositional approach goal orientation experienced more flow and reported higher affective well-being when they were assigned to the approach goal. In contrast, soccer players with a strong dispositional avoidance goal orientation benefited from being assigned an avoidance goal in terms of their flow experience and affective well-being. The results are discussed critically with respect to their theoretical and practical implications.

Training kognitiver Anteile des Gruppenhandelns im Sport

Der Fokus dieses Beitrags ist darauf gerichtet, ob und unter welchen Bedingungen sich ein kognitives Training dazu eignet, auf Gruppenebene zu einer verbesserten Leistung beizutragen. Dabei geht es auf einer allgemeineren kollektiven Ebene um die Verbesserung des Handelns von Gruppen durch Optimierung kognitiver Prozesse. In diesem Beitrag soll zu diesem Zweck ein Versuch unternommen werden, die folgenden drei Fragen zu beantworten: 1. Was sind die bei Handlungen von Gruppen zu regulierenden Prozesse? Mit anderen Worten geht es darum, eine Vorstellung davon zu entwickeln, wie erfolgreiche Handlungen von Gruppen eigentlich organisiert sind. 2. Was sind die regulierenden kognitiven Instanzen? Anders gesagt, welche Repräsentationen liegen wo vor, die dazu beitragen, die Handlungen von Gruppen zu optimieren? 3. Wie lassen sich welche dieser Prozesse und Instanzen durch kognitives Training optimieren? Wo sind also Ansatzpunkte, das Handeln von Teams effektiver und effizienter zu machen?

Minderung physiologischer Reaktivität auf psychosozialen Stress durch Taiji-Training - wer profitiert besonders? Eine Untersuchung moderierender Effekte von selbstberichteter dispositioneller psychologischer Stressreaktivität und Achtsamkeit.

Theoretical background and objectives: Stress reducing effects of Taiji practice have been repeatedly reported. The aim of the present study was to investigate which persons benefit the most from Taiji practice in terms of reduced physiological stress reactivity. Methods: We conducted a secondary data analysis of a randomized controlled Taiji trial that significantly lowered stress reactivity of salivary cortisol and alpha-amylase in a Taiji group (n = 26) compared to a control group (n = 23). By using hierarchical regression analyses potential moderating influences of self-reported trait-mindfulness and trait values of general psychological stress reactivity on stress protective effects of a three months Taiji training were examined. Moderator variables were assessed at the beginning of the study using the Freiburg-Mindfulness-Inventory and the Perceived- Stress-Reactivity-Scale. Results: The interaction effect "study group x mindfulness" was significant for stress reactivity of salivary alpha-amylase (p = 0.050). Participants in the Taiji group with higher trait-mindfulness showed a lower salivary alpha-amylase stress reactivity, while in the control group higher trait-mindfulness was associated with higher alpha-amylase stress reactivity. In the control group (p = 0.042) but not in the Taiji group (p = 0.69) salivary cortisol stress reactivity was significantly increased in persons with higher trait-mindfulness scores. We could not find moderating effects of general psychological stress reactivity. Conclusion: Our results suggest that without intervention higher trait-mindfulness is associated with increased physiological stress reactivity. Persons with higher trait-mindfulness seem to benefit the most from practicing Taiji in terms of reduced sympathetic stress reactivity.

Wake up. Back to Bed – Zugang zum nächtlichen Training?

Einleitung Ein Klartraum ist definiert als ein Traum, in dem der Träumende weiß, dass er träumt. In der Fachliteratur finden sich verschiedene Induktionstechniken, um die Klartraum-häufigkeit zu steigern (z.B. Stumbrys, Erlacher, Schädlich & Schredl, 2012). Zudem wurde in einer Pilotstudie gezeigt, dass ein Training im Klartraum zu Verbesserungen in einer Zielwurfaufgabe am nächsten Morgen führt (Erlacher & Schredl, 2010). Um ein regelmäßiges Training im Traum zu ermöglichen, besteht für die Sportpraxis das Problem, Klarträume gezielt zu induzieren. In dieser Studie wurde im Schlaflabor die so genannte Memnotische Induktion von luziden Träumen (MILT) – eine Autosugges-tionstechnik in der die Intention, einen Klartraum zu erleben, an Traumhinweise ge-koppelt wird – im Morgenschlaf überprüft. Methoden Insgesamt wurden 52 Versuchsteilnehmer (32 männlich und 20 weiblich) im Alter von 24 Jahren (± 2.2) im Schlaflabor untersucht. Die Personen waren in 4 Gruppen aufge-teilt. Alle Personen schliefen zunächst für ca. 6 Stunden, wurden dann aus einer REM-Phase geweckt und sollten einen Traum berichten. Im Anschluss blieben die Teilnehmer 30 bzw. 60 Minuten wach und praktizierten entweder MILT oder beschäf-tigten sich mit einer kognitiven oder motorischen Kontrollaufgabe. Im Anschluss durf-ten alle Teilnehmer für max. 4 weitere Stunden schlafen. Das Auftreten eines Klartraums in der morgendlichen Schlafphase diente als abhängige Variable. Ergebnisse und Diskussion Die Ergebnisse zeigen, dass MILT zu einer gesteigerten Klartraumhäufigkeit (33-70%) im Vergleich zur Kontrollbedingung (9-14%) führt. Ein Unterschied zwischen 30 Minuten (50%) zu 60 Minuten MILT (70%) ist marginal. Das Auftreten von Klarträumen kann durch MILT im Morgenschlaf signifikant gestei-gert werden. Die Erfolgsquote schwankt jedoch mit Blick auf die genaue Definition ei-nes Klartraums. Es konnten bei nicht klartraumerfahrenen Versuchsteilnehmerinnen mehr Klarträume induziert werden. Für die Sportpraxis könnten solche Induktions-techniken dem Sportler ermöglichen, im Traum zu trainieren. In weiteren Studien wäre zu untersuchen, ob Athleten ebenfalls Klarträume induziert werden können. Ebenso sollte die Auswirkung eines regelmäßigen Klartraumtrainings in der Sportpraxis wei-ter untersucht werden. Literatur Stumbrys, T., Erlacher, D., Schädlich, M. & Schredl, M. (2012).

Training einer Fingersequenz im Klartraum: Ein Vergleich mit körperlichem und mentalem Training

Das Training im Klartraum ist eine Art von mentalem Training, wobei der Träumende wäh-rend des nächtlichen REM-Traums seine motorischen Fertigkeiten übt (Erlacher, Stumbrys & Schredl, 2011). In einer Pilotstudie konnten Erlacher und Schredl (2010) zei-gen, dass die Trefferleistung einer Zielwurfaufgabe durch ein Training im Klartraum (KTT) verbessert werden kann. In der vorliegenden Studie soll dieses Ergebnis mit einer Fingersequenzaufgabe repliziert werden. Die Resultate sollen dabei mit einer körperlich trainierenden Gruppe (KT), einer mental trainierenden Gruppe (MT) und einer Kontroll-gruppe (KG) verglichen werden

Perceptual Training in Beach Volleyball Defence: Different Effects of Gaze-Path Cueing on Gaze and Decision-Making

For perceptual-cognitive skill training, a variety of intervention methods has been proposed, including the so-called “color-cueing method” which aims on superior gaze-path learning by applying visual markers. However, recent findings challenge this method, especially, with regards to its actual effects on gaze behavior. Consequently, after a preparatory study on the identification of appropriate visual cues for life-size displays, a perceptual-training experiment on decision-making in beach volleyball was conducted, contrasting two cueing interventions (functional vs. dysfunctional gaze path) with a conservative control condition (anticipation-related instructions). Gaze analyses revealed learning effects for the dysfunctional group only. Regarding decision-making, all groups showed enhanced performance with largest improvements for the control group followed by the functional and the dysfunctional group. Hence, the results confirm cueing effects on gaze behavior, but they also question its benefit for enhancing decision-making. However, before completely denying the method’s value, optimisations should be checked regarding, for instance, cueing-pattern characteristics and gaze-related feedback.

Involuntary reflexive pelvic floor muscle training in addition to standard training versus standard training alone for women with stress urinary incontinence: study protocol for a randomized controlled trial

BACKGROUND Pelvic floor muscle training is effective and recommended as first-line therapy for female patients with stress urinary incontinence. However, standard pelvic floor physiotherapy concentrates on voluntary contractions even though the situations provoking stress urinary incontinence (for example, sneezing, coughing, running) require involuntary fast reflexive pelvic floor muscle contractions. Training procedures for involuntary reflexive muscle contractions are widely implemented in rehabilitation and sports but not yet in pelvic floor rehabilitation. Therefore, the research group developed a training protocol including standard physiotherapy and in addition focused on involuntary reflexive pelvic floor muscle contractions. METHODS/DESIGN The aim of the planned study is to compare this newly developed physiotherapy program (experimental group) and the standard physiotherapy program (control group) regarding their effect on stress urinary incontinence. The working hypothesis is that the experimental group focusing on involuntary reflexive muscle contractions will have a higher improvement of continence measured by the International Consultation on Incontinence Modular Questionnaire Urinary Incontinence (short form), and - regarding secondary and tertiary outcomes - higher pelvic floor muscle activity during stress urinary incontinence provoking activities, better pad-test results, higher quality of life scores (International Consultation on Incontinence Modular Questionnaire) and higher intravaginal muscle strength (digitally tested) from before to after the intervention phase. This study is designed as a prospective, triple-blinded (participant, investigator, outcome assessor), randomized controlled trial with two physiotherapy intervention groups with a 6-month follow-up including 48 stress urinary incontinent women per group. For both groups the intervention will last 16 weeks and will include 9 personal physiotherapy consultations and 78 short home training sessions (weeks 1-5 3x/week, 3x/day; weeks 6-16 3x/week, 1x/day). Thereafter both groups will continue with home training sessions (3x/week, 1x/day) until the 6-month follow-up. To compare the primary outcome, International Consultation on Incontinence Modular Questionnaire (short form) between and within the two groups at ten time points (before intervention, physiotherapy sessions 2-9, after intervention) ANOVA models for longitudinal data will be applied. DISCUSSION This study closes a gap, as involuntary reflexive pelvic floor muscle training has not yet been included in stress urinary incontinence physiotherapy, and if shown successful could be implemented in clinical practice immediately.

The application of biomechanics to penalty corner drag-flick training: a case of Study

The penalty corner is one of the most important game situations in field hockey with one third of all goals resulting from this tactical situation. The aim of this study was to develop and apply a training method, based on previous studies, to improve the drag- flick skill on a young top-class field hockey player. A young top-class player exercised three times per week using specific drills over a four week period. A VICON optoelectronic system (Oxford Metrics, Oxford, UK) was employed to capture twenty drag-flicks, with six cameras sampling at 250 Hz, prior and after the training period. In order to analyze pre- and post-test differences a dependent t-test was carried out. Angular velocities and the kinematic sequence were similar to previous studies. The player improved (albeit not significantly) the angular velocity of the stick. The player increased front foot to the ball at T1 (p < 0.01) and the drag-flick distances. The range of motion from the front leg decreased from T1 to T6 after the training period (p < 0.01). The specific training sessions conducted with the player improved some features of this particular skill. This article shows how technical knowledge can help with the design of training programs and whether some drills are more effective than others.

Injuries in strength training: review and practical application

Purpose: This systematic review examines what is known about injuries in strength training. Methods: A systematic search was performed in PubMed and SportDiscus. Studies were included if they examined powerlifters, weightlifters, strongman athletes, bodybuilding athletes, individuals who undertook recreational weight training or weight training to complement athletic performance. Exposure variables were incidence, severity and body part injury. Results: After examining 1214 titles and abstracts, 62 articles were identified as potentially relevant. Finally, 11 were included in this systematic review. Conflicting results were reported on the relationships between injury definition and incidence or severity recorded. The lower back followed by the shoulder and knee are the most frequently affected areas in strength sports. Conclusion: Strength training is safe. However, the variety of injury definitions has makes it difficult to compare different studies in this field. New styles of reporting injuries have appeared, and could make increases these ratios. If methodological limitations in measuring incidence rate and severity injuries can be resolved, more work can be conducted to define the real incidence rate, compare it with others sports, and explore cause and effect relationships in randomized controlled trials. Key Words: strength training, injuries, specific strength sports, severity

MCT1 T1470A polymorphism influences adherence to strength training in overweight and obese men following a weight loss program

The monocarboxylate transporter (MCT) family member MCT1 transports lactate into and out of myocytes. Oxidative cells import lactate through MCT1 as a substrate, being the role of MCT1 in glycolysis-derived lactate efflux less clear. MCT1 T1470A polymorphism (rs1049434), which has been related with lactate metabolism and sports specialty 1, 2, could be an influencing factor for exercise adherence. Therefore the aim of this study was to relate the adherence to different training modalities with the T1470A MCT1 polymorphism in overweight and obese men following a weight loss program (WLP).
