The place kick in rugby.

AIM: The paper aims at studying the technical place kick in rugby, frontally to the try and at 40 meter distance. The relationship between the type of run with a predefined number of holds (1 to 4), the kinematics variables (the angle variation of the lower limbs, at the time of loading and at the moment of the impact against the ball), the average ball movement speed were assessed. METHODS: Six men national athletes, took part in the study. All the kicks were video-recorded with two high speed (210 Hz) digital cameras, and processed with Dartfish 5.5Pro software. RESULTS: According to the type of run, significant differences were reported on the run time (P<0.01) which correlated with the average ball movement speed (r=0.241; P<0.05). CONCLUSION: The analysis of the different types of runs lead to the definition of the best possible conditions for such a specific sport move, to be suggested during application or training for specialised athletes.

[Obstructive peripheral athero-arteriosclerotic vascular diseases. Apparent pathogenetic role of hormono-metabolic changes]. / Vasculopatie periferiche ostruttive atero-arteriosclerotiche. Apparente ruolo patogenetico di alcune alterazioni ormono-metaboliche.

We determined by comparison, in 30 patients with arteriosclerosis obliterans and in 10 normal peoples, 50-70 years aged, the values of some glycolipidic parameters (blood glucose, triglyceridemia, cholesterolemia, nephaemia, beta- and pre-beta-lipoproteinemia) and moreover the hormonal ones (IRI, GH, cortisolemia) at fast in the morning, during the whole day and during some blocking and stimulating tests. Patients with arteriosclerosis obliterans presented a significant alteration of the lipidic outline (hyper-lipoproteinemia of IV type sec. Fredr) and of the carbohydrate metabolism, emphasized at the OGTT by a dissimilar tolerance (normal, borderline and pre-diabetic type) referring to a normal high and low insulin immission respectively. We dissert widely about biohumural data, as reflexes involved from the pancreatic function and from the ischaemic process, and we report the eventual tie between the detected hormone-metabolic disorders and the development of arteriosclerotic occlusive disease in the lower extremities.
