The aims of this study were to compare the physical performance profile of football players with cerebral palsy (CP), according to their age, consider the sport class (FT1, FT2, and FT3), and analyse the relationship between their age and their physical performance. The physical performance of seventy-five CP football players from the Spanish CP Football National Competition was assessed. A one-way analysis of variance did not reveal physical performance differences between CP football players classified into four age-groups (< 20; 20–29.9; 30–34.9; > 35vyears). The Pearson's correlation analysis did not show a correlation between players’ physical performance and their age, except for dribbling ability in the overall sample (r = 0.25; P = 0.037). The linear regression analysis showed that the age only predicted the dribbling ability (β = 0.25; P < 0.05) but with low explained variance (R2 = 0.06). The main finding of the present study reveals no systematic differences in physical performance between CP football players according to their age.
Les objectifs de cette étude étaient (1) de comparer le profil de performance physique des joueurs de football porteurs d’une infirmité motrice cérébrale (IMC), en fonction de leur âge, et en considérant la classe sportive (FT1, FT2 et FT3), et (2) d’analyser la relation entre leur âge et leur performance physique. Les performances physiques de soixante-quinze joueurs de football avec IMC participant à la compétition nationale espagnole de football ont été évaluées. Une analyse unidirectionnelle de la variance n’a pas révélé de différences de performances physiques entre les joueurs de football IMC classés en quatre catégories d’âge (< 20 ; 20–29,9 ; 30–34,9 ; > 35 ans). L’analyse de corrélation de Pearson n’a pas montré de corrélation entre les performances physiques des joueurs et leur âge, à l’exception de la capacité de dribble dans l’échantillon global (r = 0,25 ; p = 0,037). L’analyse de régression linéaire a montré que l’âge ne prédisait que la capacité de dribbler (β = 0,25 ; p < 0,05) mais avec une faible variance expliquée (R2 = 0,06). Le principal message de cette étude est que pour les tranches d’âge considérées, il n’existe aucun effet détectable de l’âge sur les performances physiques des joueurs de football IMC.

<div><h3>Objectives</h3><p>Diet and regular exercise can control blood pressure by producing adrenomedullin.

Forty subclinical hypothyroid patients, both male and female, with an average age of 30.50<!--> <!-->±<!--> <!-->6.41 years and a mean weight of 73.20<!--> <!-->±<!--> <!-->6.48<!--> <!-->kg were recruited using purposive sampling. The patients were randomized into four groups of equal size: training, training<!--> <!-->+<!--> <!-->supplement, supplement, and control (<em>n</em> <!-->=<!--> <!-->10 per group). The supplement-consuming groups received 500<!--> <!-->mg of Nasturtium officinale extract daily, whereas the training groups participated in three interval training sessions at 90–95 percent MHR intensity for eight weeks. The participants’ adrenomedullin and blood pressure levels were measured before and after the intervention.
