In Deutschland sind 15 Prozent der Kinder und Jugendlichen zwischen drei und 17 Jahren übergewichtig, über 6 Prozent leiden an Adipositas, krankhafter Fettleibigkeit mit schweren gesundheitlichen Folgen. Diese vom Robert-Koch-Institut im vergangenen Jahr ermittelten Zahlen decken sich mit unseren eigenen Untersuchungen an 11- bis 15-Jährigen in sechs hessischen Schulen. Zudem zeichnet sich ab, dass die Zahl der Übergewichtigen bei den Jugendlichen besonders ansteigt: Innerhalb der vergangenen 20 Jahre hat sich der Anteil adipöser 14- bis 17-Jähriger verdreifacht, Tendenz weiter steigend. Dies ist umso besorgniserregender, da mindestens 70 Prozent dieser Jugendlichen nicht wieder abspecken und als Erwachsene gesundheitlich schwer beeinträchtigt sind. Immerhin sind in Europa jährlich etwa eine Millionen Sterbefälle auf Folgen des Übergewichts zurückzuführen, was allein die deutsche Volkswirtschaft mit 15 Milliarden Euro im Jahr belastet. Übergewicht ist auch ein soziales Problem: Kinder aus sozial schwachen Familien und mit Migrationshintergrund tragen ein erheblich höheres Risiko. Wie unsere Erhebungen weiter vermuten lassen, sind vor allem solche Kinder betroffen, deren Eltern ebenfalls unter Übergewicht oder Adipositas leiden. Fettleibige Kinder fühlen sich oft ausgegrenzt und sozial stigmatisiert. Dies beeinträchtigt ihre psychosoziale Entwicklung erheblich. Mehr als die Hälfte der von uns befragten übergewichtigen Schulkinder fühlen sich unwohl und möchten ihr Gewicht unbedingt reduzieren. ...
Wer seine sportliche Leistung verbessern will, muss die Anforderungen beim Training kontinuierlich steigern. Das wusste schon Milon von Kroton, einer der berühmtesten Athleten der Antike. Der einstmals schwächliche Knabe begann sein Krafttraining, indem er ein neugeborenes Kalb um den Hof seiner Eltern trug. Der Legende nach fuhr er damit fort, bis das Kalb zum Stier herangewachsen war. Heutzutage bewegen sich Spitzenathleten auf einem schmalen Grat zwischen hochwirksamem Trainingsreiz und Überlastung. Die diagnostischen Methoden der Sportwissenschaft und Sportmedizin helfen ihnen, ihre Trainingsbelastungen optimal zu steuern.
Der Mensch ist dazu geschaffen, sich zu bewegen. Tut er es nicht, beispielsweise weil seine Arbeit ihn vor den Computerbildschirm zwingt und er seiner Nahrung nicht mehr hinterherjagen muss, wird er krank. So betrifft der "Altersdiabetes" inzwischen immer mehr Kinder und Jugendliche. Bei erwachsenen Männern, und zunehmend auch bei Frauen, führt die Kombination von Stress und Bewegungsarmut häufig zu Herz- und Kreislauferkrankungen. Frauen sind vor allem nach den Wechseljahren durch Osteoporose, Gebärmutterhals- und Brustkrebs bedroht. Erstmals sterben weltweit mehr Menschen an nicht übertragbaren Erkrankungen als an Infektionserkrankungen. Aber es gibt auch eine gute Nachricht: Regelmäßige körperliche Aktivität kann diesen chronischen Erkrankungen vorbeugen und spielt bei ihrer Therapie eine bedeutsame Rolle.
Fit fürs Alter – mit der Prophylaxe für körperliche, aber auch geistige Mobilität und Selbstständigkeit beginnt man idealerweise schon in Kindheit und Jugend. Wer sich in fortgeschrittenen Lebensphasen wohlfühlen und unabhängig bleiben möchte, sollte dafür sorgen, dass Beweglichkeit sowie geistige und soziale Aktivitäten immer zum Alltag gehören. Menschen, die ihre individuellen Gesundheitsressourcen so stärken, bewältigen auch Erkrankungen und gesundheitliche Probleme deutlich leichter. In diesem Zusammenhang konzentrieren sich die Frankfurter Sportmediziner auf Konzeption, Realisation und Evaluation von qualitativ hochwertigen seniorengerechten Bewegungsangeboten sowie die Entwicklung und den Wirksamkeitsnachweis spezieller Funktionstests und Hilfsmittel für Ältere. ...
Jährlich erkranken etwa 425 000 Menschen in Deutschland an Krebs. Die Tendenz ist steigend: Experten gehen davon aus, dass die Zahl der Neuerkrankungen bis zum Jahr 2030 um 50 Prozent zunehmen wird. Doch zu dieser schlechten Nachricht gibt es auch eine gute: Körperliche Aktivität und Sport können das allgemeine Risiko, an bestimmten Krebsformen zu erkranken, vermindern. Dazu zählen vor allem Darmkrebs sowie der nach den Wechseljahren auftretende Brust- und Gebärmutterschleimhautkrebs. Aber auch wer schon erkrankt ist, kann sein Wohlbefinden und Selbstvertrauen durch spezielle Bewegungsprogramme, wie sie an der Goethe-Universität entwickelt werden, steigern. Selbst die Leiden von Patienten mit fortgeschrittenen Krebserkrankungen lassen sich auf diese Weise lindern. Denn Bewegung beeinflusst nicht nur die unmittelbar tumorbedingten Symptome, sondern auch therapiebedingte Nebenwirkungen, insbesondere die der Chemotherapie.
Lockdown measures during the COVID-19 pandemic have led to reductions in physical activity (PA) worldwide. Leading public health organizations have recommended the use of online exercise classes (OEC) to compensate the loss of regular exercise classes. As of now, no data are available on the uptake of OEC and on users’ attitudes. The aim of the current online survey was to assess the use of and attitudes towards OEC in Germany. Respondents indicated awareness and use of OEC, and levels of agreement with statements on OEC. Frequency of awareness and use of OEC according to PA status were calculated with contingency tables and the Χ2 test. Differences between users and non-users were tested with the Student’s t-test and the Mann–Whitney U test. Data on attitudes are presented as percentages, and Spearman correlations were calculated between attitudes and activity status, frequency of use, educational attainment, age and body mass index. A total of 979 datasets were analyzed. Of the respondents, 681 were aware of and 180, 118 and 84 used them <1 per week, 1–2 per week and ≥3 per week, respectively. Significantly more active respondents were aware of and used OEC compared to less active respondents. All in all, regular OEC use was quite limited. OEC was differentially attractive to people according to PA status, frequency of use, BMI and age. Tailoring OEC to current non-users and adding motivational support might enhance the regular use of OEC.
Physical activity counseling in primary health care is regarded as a useful complementary preventive and therapeutic measure and is advocated by leading public health institutions. This integrative review summarizes the available data on physical activity counseling in primary care in Germany. A systematic literature search in various databases (peer reviewed and grey literature) was carried out for quantitative and qualitative studies on physical activity counseling and use of “Exercise on Prescription”. The 25 studies included show a very high methodological diversity and, in some cases, considerable risks of bias, with limited comparability across studies. Counseling was provided in all studies by physicians. They report frequent physical activity counseling, which is partly confirmed and partly refuted by patient data. The use of “Exercise on Prescription” is at a very low level. Information on the frequency of physical activity counseling in Germany varies depending on data source and is sometimes contradictory. Our review provides a synthesis of various perspectives on routine physical activity counseling in primary care in Germany. Future studies using standardized and validated instruments in representative samples are needed to further knowledge on counseling and to be able to establish trends in prevalence. Strengthening the topics of physical activity and health and physical activity counseling in medical curriculum is strongly recommended.
Lockdown measures including the closure of physical activity facilities were installed against the spread of the novel coronavirus in March 2020. The aim of the current online survey was to assess the lockdown effects on physical activity in German adults. We assessed physical activity using the European Health Interview Survey (EHIS) questionnaire. Pre-lockdown vs. lockdown differences were tested with the X2 test and the Student’s t-test for paired data. Predictor variables to explain compliance with physical activity recommendations were identified using a fixed effects binary logistic regression analysis. Data of 979 respondents were analyzed. Transport related and leisure time physical activity decreased (p < 0.001, d = 0.16; p < 0.001, d = 0.22, respectively). Compliance with physical activity recommendations decreased from 38.1% to 30.4% (chi2 [1, 1958] = 12.754, p < 0.001, V = 0.08). In the regression analysis, BMI (OR 0.944, 95% CI 0.909–0.981; p = 0.003), education (OR 1.111, 95% CI 1.021–1.208; p = 0.015), transport related (OR 1.000, 95% CI 1.000–1.000; p = 0.008) and leisure time physical activity (OR 1.004, 95% CI 1.003–1.004; p < 0.001), muscle strengthening (OR 5.206, 95% CI 4.433–6.114; p < 0.001), as well as the ‘lockdown vs. normal’ categorical variable (OR 0.583, 95% CI 0.424–0.802; p = 0.001) showed a contribution, while sex (p = 0.152), age (p = 0.266), work related physical activity (p = 0.133), and remote working (p = 0.684) did not. Physical activity declined in German adults, and should also be promoted in light of the emerging evidence on its protective effects of against COVID-19. Special attention should be given to muscle strengthening activities and groups with lower educational attainment.
Investigation of the sympathetic regulation in delayed onset muscle soreness: results of an RCT
(2021)
Sports-related pain and injury is directly linked to tissue inflammation, thus involving the autonomic nervous system (ANS). In the present experimental study, we disable the sympathetic part of the ANS by applying a stellate ganglion block (SGB) in an experimental model of delayed onset muscle soreness (DOMS) of the biceps muscle. We included 45 healthy participants (female 11, male 34, age 24.16 ± 6.67 years [range 18–53], BMI 23.22 ± 2.09 kg/m2) who were equally randomized to receive either (i) an SGB prior to exercise-induced DOMS (preventive), (ii) sham intervention in addition to DOMS (control/sham), or (iii) SGB after the induction of DOMS (rehabilitative). The aim of the study was to determine whether and to what extent sympathetically maintained pain (SMP) is involved in DOMS processing. Focusing on the muscular area with the greatest eccentric load (biceps distal fifth), a significant time × group interaction on the pressure pain threshold was observed between preventive SGB and sham (p = 0.034). There was a significant effect on pain at motion (p = 0.048), with post hoc statistical difference at 48 h (preventive SGB Δ1.09 ± 0.82 cm VAS vs. sham Δ2.05 ± 1.51 cm VAS; p = 0.04). DOMS mediated an increase in venous cfDNA -as a potential molecular/inflammatory marker of DOMS- within the first 24 h after eccentric exercise (time effect p = 0.018), with a peak at 20 and 60 min. After 60 min, cfDNA levels were significantly decreased comparing preventive SGB to sham (unpaired t-test p = 0.008). At both times, 20 and 60 min, cfDNA significantly correlated with observed changes in PPT. The 20-min increase was more sensitive, as it tended toward significance at 48 h (r = 0.44; p = 0.1) and predicted the early decrease of PPT following preventive stellate blocks at 24 h (r = 0.53; p = 0.04). Our study reveals the broad impact of the ANS on DOMS and exercise-induced pain. For the first time, we have obtained insights into the sympathetic regulation of pain and inflammation following exercise overload. As this study is of a translational pilot character, further research is encouraged to confirm and specify our observations.
Beneficial acute effects of resistance exercise on cognitive functions may be modified by exercise intensity or by habitual physical activity. Twenty-six participants (9 female and 17 male; 25.5 ± 3.4 years) completed four resistance exercise interventions in a randomized order on separate days (≥48 h washout). The intensities were set at 60%, 75%, and 90% of the one repetition maximum (1RM). Three interventions had matched workloads (equal resistance*nrepetitions). One intervention applied 75% of the 1RM and a 50% reduced workload (resistance*nrepetitions = 50%). Cognitive attention (Trail Making Test A—TMTA), task switching (Trail Making Test B—TMTB), and working memory (Digit Reading Spans Backward) were assessed before and immediately after exercise. Habitual activity was assessed as MET hours per week using the International Physical Activity Questionnaire. TMTB time to completion was significantly shorter after exercise with an intensity of 60% 1RM and 75% 1RM and 100% workload. Friedman test indicated a significant effect of exercise intensity in favor of 60% 1RM. TMTA performance was significantly shorter after exercise with an intensity of 60% 1RM, 90% 1RM, and 75% 1RM (50% workload). Habitual activity with vigorous intensity correlated positively with the baseline TMTB and Digit Span Forward performance but not with pre- to post-intervention changes. Task switching, based on working memory, mental flexibility, and inhibition, was beneficially influenced by acute exercise with moderate intensity whereas attention performance was increased after exercise with moderate and vigorous intensity. The effect of regular activity had no impact on acute exercise effects.
