Aim
The aim of the study was to compare aerobic and anerobic abilities of prepubertal children and adults with the critical power concept.Methods
Sixteen children (10.3 ± 0.9 years) and 15 adults (23.5 ± 3.6 years) performed five tests: a maximal-graded test and four constant load exercises until exhaustion. Critical power (CP) and anaerobic-work capacity (CTA) were determined from the power-1/time (P-t) linear relationship.Results
Determination coefficients for P-t were 0.94 ± 0.05 in children and 0.96 ± 0.04 in adults. PC values were significantly (p < 0.01) lower in children (2.7 ± 0.4 W/kg) than in adults (3.1 ± 0.3 W/kg). CTA values were significantly (p < 0.001) lower in children (136.4 ± 50.8 J/kg) than in adults (247.1 ± 45.7 J/kg).Conclusion
Satisfying determination coefficients for CP and CTA were found in children and adults. Children have a lower CP and CTA than adults. This result is in accordance with literature. 相似文献5.

Protecting the health of the athlete is the primary goal of the International Olympic Committee's Medical Commission. One of its main objectives is the promotion of safe practices in the training of the elite child athlete. The elite child athlete is one who has superior athletic talent, undergoes specialised training, receives expert coaching and is exposed to early competition. Sport provides a positive environment that may enhance the physical growth and psychological development of children. This unique athlete population has distinct social, emotional and physical needs, which vary depending on the athlete's particular stage of maturation. The elite child athlete requires appropriate training, coaching and competition that ensure a safe and healthy athletic career and promote future well-being. This document reviews the scientific basis of sports training in the child, the special challenges and unique features of training elite children and provides recommendations to parents, coaches, health care providers, sports governing bodies and significant other parties. 相似文献

Topics – The chronic stress syndrome can be defined as a state in which an intramuscular increase in pressure in a limited space (osteo-aponevrotic compartment) compromises the circulation and the function of muscular and nervous tissues located inside this space. For anatomic reasons, the anterior and lateral aspect of the leg of the young and sporting subject is more often affected than the posterior compartment. The other localizations of the leg and those interesting the arm are less frequent but are still underestimated. The clinical and differential diagnosis rests on: a predisposing ground (pathology of overuse); a characteristic pain (topography, evolution); a normal clinical examination at rest. The diagnosis is confirmed by the measurement of the intramuscular pressures above a critical point during the effort, but also by a too slow return to the pressures of rest after stop of the effort. The advantage of the other complementary examinations, aside the bon scan or else the RMN, is to eliminate the differential diagnoses.Conclusion – The treatment of a chronic stress syndrome is above all surgical for the medical treatments cannot make completely disappear the existence of a painful threshold to the effort. The surgical treatment by sub cutaneous aponevrotomy or aponevrectomy is the rule in the sportsman eager to continue his activity with approximately 90% good results. 相似文献
