Abstract

The lactate threshold person "means the concentration of individual athletes in blood lactate in the incremental exercise to some extent, lactate production and clearance of the threshold for the loss of dynamic balance, lactate blood started strong augmentation. To improve the function and athletic performance student volleyball players, the use of the individual characteristics of lactate threshold volleyball, volleyball, aerobic endurance training, and an analysis of lactate threshold individual 'to improve student athlete's volleyball physical theory in practice. The curve of the lactate trained athlete is deflected to the right. This adaptation to training participated in the belief that lactic acid is responsible for fatigue. The idea is that if the rate is less important in an athlete more so driven harder, the inefficiency of the novice is the fact of increased lactate levels. Therefore, the improvement involves a lower lactate production. We will see the error that accompanies this reasoning.

Introduction

Lactate threshold is more reliable than the maximum oxygen consumption. Mainly by heart and lung muscles can be affected by the constraints, and the lactate threshold reflects mainly in the muscle Skeletal use oxygen, strengthen and improve the lactate threshold outstanding athletic ability and athletic performance of a large report. Lactate is an organic compound consisting of carbon, hydrogen and oxygen. The chemical formula is C3H5O3 lactate and occurs naturally in the body of each person. Besides being a byproduct of exercise, is also a fuel for this. It is found in muscle, blood and various organs. The human body needs it to function properly. Lactic acid is the final product of glycolysis, being their primary source decomposition of a carbohydrate called glycogen; it decomposes and is converted into a substance called pyruvate, and its chemical formula C3H3O3 very similar to lactate, during this process produces energy. We often refer to this process as anaerobic energy because it uses oxygen. When pyruvate is broken down further, producing more energy and its transformation process occurs in the presence of O2 in muscle mitochondria. This energy is aerobic because this additional process uses oxygen. If the pyruvate is not broken usually becomes lactate, present in our system while we rest and during our daily activities, albeit at very low levels.

In 100 years of research, lactic acid has almost become a myth. Shown to be responsible then fatigue indicator, it is increasingly an indicator used to assess the impact of training. Some coaches even offer complete drive systems based on the level lactic reached. In this paper we try to distinguish between belief and reality of lactic acid. We take into account the different aspects of this metabolite: its production, its path through the body, its evolution as a function of exercise intensity. Finally, we consider the usefulness it may have under the training monitoring and forecasting performance.

Knowing the VO2 max is to know the aerobic potential of a subject, know the lactate threshold is to know (%) as of that aerobic capacity can be used without entering tiring process and loss ...
