Die Unzufriedenheit mit Gewicht und Figur gilt als bedeutsamer Risikofaktor für die Entstehung von gestörtem Essverhalten und Essstörungen im Vollbild und steht mit reduziertem psychischem Wohlbefinden in Zusammenhang. Aufgrund der hohen klinischen Relevanz wurden Gewichts- /Figursorgen v. a. bei weiblichen Jugendlichen und jungen Erwachsenen vielfach untersucht. Muskelsorgen – als männliches Äquivalent betrachtet – stießen erst im Verlauf der letzten 20 Jahren auf vermehrtes Interesse in der psychologischen Forschung. Die aktuellen westlichen Schönheitsideale legen jedoch die Relevanz von Gewicht, Figur und Muskulosität in Bezug auf aussehensbezogene Sorgen bei beiden Geschlechtern nahe. In der vorliegenden Dissertation wurden deshalb die folgenden Fragestellungen thematisiert: (1) Auftreten: Wie sind Gewichts- /Figursorgen und Muskelsorgen bei weiblichen und männlichen Jugendlichen und jungen Erwachsenen ausgeprägt? Wie verändern sie sich über 20 Monate? Welche Profile lassen sich bezüglich ihres Auftretens definieren? (2) Einflussfaktoren: Welchen Einfluss haben Alter, Gewichtsstatus, negative Affektivität und Internalisierung des Schönheitsideals auf Gewichts- /Figursorgen und Muskelsorgen? (3) Folgen: Welchen Einfluss haben Gewichts-/Figursorgen und Muskelsorgen auf essensbezogene Sorgen, restriktives Essverhalten, Binge Eating, zwanghaftes Bewegungsverhalten, Verhaltensweisen zum Muskelaufbau und negative Affektivität?
Es konnte gezeigt werden, dass mehr Mädchen von aussehensbezogenen Sorgen betroffen sind und diese im Mittel höher ausgeprägte Gewichts-/Figursorgen zeigen, während Jungen höher ausgeprägte Muskelsorgen berichten. Eine differenzierte Analyse verschiedener Subgruppen legt jedoch nahe, dass es in Gruppen mit ausgeprägten aussehensbezogenen Sorgen keine Geschlechtsunterschiede bezüglich Gewichts-/Figursorgen und Muskelsorgen gibt. Dieser Befund unterstreicht die Relevanz beider Aspekte bei beiden Geschlechtern und legt eine entsprechende Erfassung in zukünftigen Studien nahe. Des Weiteren ergaben sich Ansatzpunkte für die Notwendigkeit der Prävention bei Mädchen mit Übergewicht/Adipositas im späten Jugend- und frühen Erwachsenenalter ebenso wie bei Jungen mit Untergewicht sowie Übergewicht/Adipositas. Neben Gewichts-/Figursorgen sollte bei weiblichen Jugendlichen und jungen Erwachsenen auch die Internalisierung des schlanken Ideals thematisiert werden, um der Entstehung von auffälligem Ess- und Bewegungsverhalten vorzubeugen. Bei beiden Geschlechtern zeigte sich außerdem die Internalisierung des athletischen Ideals als relevanter Ansatzpunkt für die Vorbeugung von Verhaltensweisen zum Muskelaufbau. Darüberhinaus konnten bei beiden Geschlechtern sowohl für Gewichts-/Figursorgen, als auch für Muskelsorgen Zusammenhänge mit potentiell gesundheitsschädlichen Verhaltensweisen gezeigt werden.
Zusammenfassend gelang in der vorliegenden Arbeit eine differenzierte Analyse von Auftreten, Einflussfaktoren und Folgen von Gewichts-/Figursorgen und Muskelsorgen bei Jugendlichen und jungen Erwachsenen. Mittels, großteils prospektiver, latenter Modelle und manifester Pfadanalysen konnten bisherige Befunde überprüft und erste Befunde zu den Forschungslücken in Bezug auf Muskelsorgen bei weiblichen Jugendlichen und jungen Erwachsenen berichtet werden.
Introduction: Studies that combined balance and resistance training induced larger performance improvements compared with single mode training. Agility exercises contain more dynamic and sport-specific movements compared with balance training. Thus, the purpose of this study was to contrast the effects of combined balance and plyometric training with combined agility and plyometric training and an active control on physical fitness in youth.
Methods: Fifty-seven male soccer players aged 10–12 years participated in an 8-week training program (2 × week). They were randomly assigned to a balance-plyometric (BPT: n = 21), agility-plyometric (APT: n = 20) or control group (n = 16). Measures included proxies of muscle power [countermovement jump (CMJ), triple-hop-test (THT)], muscle strength [reactive strength index (RSI), maximum voluntary isometric contraction (MVIC) of handgrip, back extensors, knee extensors], agility [4-m × 9-m shuttle run, Illinois change of direction test (ICODT) with and without the ball], balance (Standing Stork, Y-Balance), and speed (10–30 m sprints).
Results: Significant time × group interactions were found for CMJ, hand grip MVIC force, ICODT without a ball, agility (4 m × 9 m), standing stork balance, Y-balance, 10 and 30-m sprint. The APT pre- to post-test measures displayed large ES improvements for hand grip MVIC force, ICODT without a ball, agility test, CMJ, standing stork balance test, Y-balance test but only moderate ES improvements with the 10 and 30 m sprints. The BPT group showed small (30 m sprint), moderate (hand grip MVIC, ICODTwithout a ball) and large ES [agility (4 m × 9 m) test, CMJ, standing stork balance test, Y-balance] improvements, respectively.
Conclusion: In conclusion, both training groups provided significant improvements in all measures. It is recommended that youth incorporate balance exercises into their training and progress to agility with their strength and power training.

Today's adolescents grow up using information and communication technologies as an integral part of their everyday life. This affords them with extensive opportunities, but also exposes them to online risks, such as cybergrooming and cyberbullying victimization. The aims of this study were to investigate correlates of cybergrooming and cyberbullying victimization and examine whether victims of both cybergrooming and cyberbullying (dual-cybervictims) show higher involvement in compulsive Internet use (CIU) and troubled offline behavior (TOB) compared to victims of either cybergrooming or cyberbullying (mono-cybervictims). The sample consisted of 2,042 Dutch, German, Thai, and U.S. adolescents (age = 11–17 years; M = 14.2; SD = 1.4). About every ninth adolescent (10.9 percent) reported either mono- or dual-cybervictimization. Second, both CIU and TOB were associated with all three types of cybervictimization, and finally, both CIU and TOB were more strongly linked to dual-cybervictimization than to both forms of mono-cybervictimization. These findings contribute to a better understanding of the associations between different forms of cybervictimization and psychological health and behavior problems among adolescents.
Symptoms of anxiety and depression in young athletes using the Hospital Anxiety and Depression Scale
(2018)
Elite young athletes have to cope with multiple psychological demands such as training volume, mental and physical fatigue, spatial separation of family and friends or time management problems may lead to reduced mental and physical recovery. While normative data regarding symptoms of anxiety and depression for the general population is available (Hinz and Brahler, 2011), hardly any information exists for adolescents in general and young athletes in particular. Therefore, the aim of this study was to assess overall symptoms of anxiety and depression in young athletes as well as possible sex differences. The survey was carried out within the scope of the study "Resistance Training in Young Athletes" (KINGS-Study). Between August 2015 and September 2016, 326 young athletes aged (mean +/- SD) 14.3 +/- 1.6 years completed the Hospital Anxiety and Depression Scale (HAD Scale). Regarding the analysis of age on the anxiety and depression subscales, age groups were classified as follows: late childhood (12-14 years) and late adolescence (15-18 years). The participating young athletes were recruited from Olympic weight lifting, handball, judo, track and field athletics, boxing, soccer, gymnastics, ice speed skating, volleyball, and rowing. Anxiety and depression scores were (mean +/- SD) 4.3 +/- 3.0 and 2.8 +/- 2.9, respectively. In the subscale anxiety, 22 cases (6.7%) showed subclinical scores and 11 cases (3.4%) showed clinical relevant score values. When analyzing the depression subscale, 31 cases (9.5%) showed subclinical score values and 12 cases (3.7%) showed clinically important values. No significant differences were found between male and female athletes (p >= 0.05). No statistically significant differences in the HADS scores were found between male athletes of late childhood and late adolescents (p >= 0.05). To the best of our knowledge, this is the first report describing questionnaire based indicators of symptoms of anxiety and depression in young athletes. Our data implies the need for sports medical as well as sports psychiatric support for young athletes. In addition, our results demonstrated that the chronological classification concerning age did not influence HAD Scale outcomes. Future research should focus on sports medical and sports psychiatric interventional approaches with the goal to prevent anxiety and depression as well as teaching coping strategies to young athletes.
