La fréquence cardiaque d'entraînement est calculée selon Karvonen en se basant sur la fréquence cardiaque de réserve qui correspond à la soustraction de la fréquence cardiaque de repos à la fréquence cardiaque maximale. Les étapes du calcul de la fréquence d'entrainement selon Karvonen 1 Déterminer la fréquence cardiaque maximale (FC max) La fréquence cardiaque maximale n'est pas affectée par l'entraînement. Le coeur d'un sportif ne grimpe pas plus haut que celui d'un sédentaire.
En revanche, elle diminue progressivement avec l'âge. Astrand, physiologiste suédois, a établi une formule pour évaluer globalement cette diminution : FC max= 220 - l'âge +/- 10 pulsations. Pour toutes ces raisons, on ne peut pas prendre la formule d'Astrand en référence. 2 Mesurer sa fréquence cardiaque de repos (FCR) 3 Calculer sa fréquence cardiaque de réserve On obtient la fréquence cardiaque de réserve en soustrayant la fréquence cardiaque de repos à la fréquence cardiaque maximale.

The Most Important Running Stretches. There is quite a bit of debate between runners about running stretches and strengthening exercises. Is it good for you or not? Do you stretch before and / or after your run? Which stretches do you do, if any? To start of with answering the first question : yes, stretches, if performed properly, are good for you. This leaves the last two questions as topics for this article: Do you stretch before and / or after your run ? Which running stretches are good for you ? Stretching and strengthening before and / or after the run ? As said, there is quite some debate on the issue of stretching and strenghtening. Latest few articles I read about the topic say what I have been believing for a long while: Stretching before you run is of no or little use, but harmless. So, what do I do before my run? Just head out of the door and go for it? Well, when I have an easy run or recovery run planned, then yes. But not by doing stretching and strengthening exercises.
After my body has warmed up a bit, I go faster. Jogging Stretches For The Knee. Patella femoral syndrome is a common occurrence in athletes due to the extra stain placed on the knees when running or climbing. The patella is the knee bone while the femur is the thighbone that attaches to the patella. Patella femoral syndrome causes pain in the back of the knee.
Initial symptoms may include pain with exercise and progress into loss of knee alignment because the ligaments around the knee have become weakened. This condition can cause the ligaments and muscles in the leg to become tightened and uncomfortable, but these symptoms can be relieved through regular stretching. Patella glides are an isometric -- limited movement -- exercise that stretches the back portion of the knee. The quadriceps represent the four large muscles that comprise the front of the leg and connect to the kneecap. The hamstrings are the muscles that support the back of the leg. A weakened or tight iliotibial band can contribute to knee pain.
