Introduction: Assessment of exercise training load (TL) can identify mechanisms of fatigue and injury. At present, techniques to monitor TL in young athletes are lacking. Objectives: To examine the adherence to two monitoring techniques to assess TL among young judokas. Methods: Over a 10 week study period, TL was assessed by completion of a daily training log and by weekly measurement of heart rate variability (HRV). The satisfaction to HRV method was assessed by survey at study completion. Results: Among national caliber judokas (n=10, age 16 ± 2 y, weight 63 ± 5 kg, height 169 ± 8 cm,), training logs were completed at a 98 ± 5% rate, while HRV measurement was successful 57% ± 37%. HRV was comparable to young and athletic population. Difficulties in performing HRV measurements were rated 3.3 ± 1.9 (1: not constraining to 10: extremely constraining). Conclusion: Excellent adhesion for training diary completion was only possible with regular demands from coaches for ratings. Judo seems to enhance cardiac autonomic control in young national level athletes. HRV monitoring compliance was suboptimal among young judokas and opportunities for future improvement are suggested by our data.

The prevalence of obesity is increasing worldwide, and excess body weight is associated with a substantially increased risk of adverse health conditions. Exercise supports the prevention and management of obesity; however, when used for weight loss, exercise (even at high volumes) is usually relatively ineffective, frequently producing less weight loss than expected based on measured energy expenditure.

Exercise is medicine. This motto has become widely accepted. However, we are far from implementing it in clinical practice. This concerns both the advice given in the medical doctor and the knowledge of how to properly apply exercise as medicine. Only about 20-30% of medical doctors advise their patients to be physically active during a GP visit.

Increased sports participation has resulted in an increased incidence of sports-related injuries. It has become increasingly clear that different sexes present with different injury profiles [1]. For instance, female athletes are more likely to sustain lower extremity injuries than males [2]. The underlying static factors include a wider pelvis, increased hip varus, femoral anteversion, as well as increased knee and external tibial torsion in the female body [2], and dynamic factors include dynamic valgus during landing [2].

Vor einigen Monaten meldete sich eine Abiturientin bei mir mit der Bitte um ein Interview für ihre Maturaarbeit. Thema ihrer Arbeit war das (mögliche) Verbot von Kopfbällen bei Kindern und Jugendlichen im Fussball. Kurz darauf stellte sich im Rahmen der Generalversammlung der Gesellschaft für pädiatrische Sportmedizin (GPS) dieselbe Frage: Wieso sind in England/USA Kopfbälle im Jugendbereich verboten, in Deutschland und der Schweiz aber nicht?
