Brief Summary: The phenomena of biological adaptation and overtraining are closely related terms that is why in sport it is possible to identify two types of overtraining The first of these is known as short-term overtraining which is required as a state of peripheral fatigue induced by repeated sessions of physical activity in short periods of time that are related to mechanisms of metabolic type is considered desirable and normal by allowing mechanisms of adaptation to be activated depending on the nature and administration of the loads which allow reaching higher yield quotas The second long-term overtraining is characterized by a series of signs and symptoms of exhaustion and persistent fatigue that take place at the level of the central nervous system and that are produced by the imbalance between demanding physical work and recovery periodsThis type of condition is also known as general syndrome of overtraining GSO unexplained low performance syndrome staleness or burnout which is propitiated by the need to achieve maximum physical performance and the performance of physical activities in a uncontrolled that cause an interruption to the processes of biological recovery that attenuate the obtaining of the physical form wished reason why the sportsman experiences a decrease of the physical and mental performance manifested in a clinical picture that reflects muscular inflammation headache elevation sudden blood pressure loss of functional capacity alterations of the central nervous system CNS metabolic endocrine and immune systems

The stretching is commonly used as a method of physical rehabilitation The actual information about how the GSO can reduce or prevent in the athlete are no cleared yet that is the way the information regarding the relationship with the GSO the stretching the expression of BDNF and the effects can produce in the regenerative capacity in the over-trained subjects and their compensatory mechanisms during the different cycles of physical exercise is null making necessary the investigation of the effects that can produce in the decrease of factors that indicate GSO
Detailed Description: Introduction The phenomena of biological adaptation and overtraining are closely related terms that is why in sport it is possible to identify two types of overtraining The first of these is known as short-term overtraining which is required as a state of peripheral fatigue induced by repeated sessions of physical activity in short periods of time that are related to mechanisms of metabolic type eg low levels of glycogen is considered desirable and normal by allowing mechanisms of adaptation to be activated depending on the nature and administration of the loads which allow reaching higher yield quotas The second long-term overtraining is characterized by a series of signs and symptoms of exhaustion and persistent fatigue that take place at the level of the central nervous system and that are produced by the imbalance between demanding physical work and recovery periods

This type of condition is also known as general syndrome of overtraining GSO unexplained low performance syndrome staleness or burnout which is propitiated by the need to achieve maximum physical performance and the performance of physical activities in a uncontrolled that cause an interruption to the processes of biological recovery that attenuate the obtaining of the physical form wished reason why the sportsman experiences a decrease of the physical and mental performance manifested in a clinical picture that reflects muscular inflammation headache elevation sudden blood pressure loss of functional capacity alterations of the central nervous system CNS metabolic endocrine and immune systems The neurotrophic factor derived from the brain BDNF influences different types of neurons in the CNS promoting their differentiation growth survival and neuroprotection by activating the mechanisms of synaptic plasticity

BDNF decreases when performing specific physical exercises with intensities under the interval mixed and high-intensity method as those who are employed in competitive cycles For its part stretching is commonly used as a method of physical rehabilitation in patients with musculoskeletal injuries of various origins Its effect reflects the restoration of motor control by interacting with the intervention and order centers that are located in different parts of the CNS that are associated with the modulation of the discharge of the motor neurons involved in the activation of the muscle spindle which allow the reflex for the execution of the movement and the control of postures The information regarding the relationship with the GSO the stretching and the expression of BDNF in the regenerative capacity in those over-trained subjects and their compensatory mechanisms during the different cycles of physical exercise is null making necessary the investigation of the effects that can produce in the decrease of factors that indicate GSO and consequently build support systems for the athlete with the purpose of returning it to a level of adequate physical performance

Problem Statement The training cycles are configured with the purpose of achieving a greater adaptation to the physical activity that is performed However those closest to the competition have more intensity and physical demands However the achievement of maximum performance and the GSO are phenomena deeply related to the adaptability of the organism The strategies commonly used to recover an athlete with GSO are directed to the care of diet and rest however do not make clear by what methods and means it is possible to perform a restoration of regenerative processes and muscle contraction to decrease of chronic fatigue and in turn the maintenance of physical performance achieved in previous cycles

Research question What are the effects of a stretching training program on BDNF expression and its relationship with biochemical and physiological markers that indicate GSO

General objective To analyze the effects of a stretching training program on the expression of BDNF and decrease of biochemical and physiological markers that indicate GSO

Methodology A clinical trial with simple blinding

Type of sampling Probabilistic simple random tombola

Sample size 72 subjects 36 subjects per group which was estimated through the equation for comparison of means

Selection criteria To be a university student males from 18 to 25 years of age to lead a moderately active or sedentary lifestyle to sign an informed consent form to take the physical fitness level test and to have been diagnosed as healthy in the clinical assessment

Attention to adverse effects These will be classified into three types milder will be those muscular discomforts present but tolerable eg delayed muscle pain stiffness edema localized fatigue loss of mobility loss of strength Moderate physical damage that interferes with physical activities such as first or second-degree sprain and first-degree muscle tear Severe those injuries andor physical damage that incapacitates the subject to perform physical activities of any kind such as ruptures severe muscular ligamentous and cartilaginous of the third degree dislocations and fractures If one of the two previous cases are presented the subjects will be assisted by the sports doctor who is part of the research protocol and channeled to the corresponding family medical clinic

Instruments Questionnaire PAR Q YOU used to know the state of health and habits of physical activity The biochemical tests will be carried out with a blood sample of 5 ml using a BD Vacutainer yellow tube model 368159 with gel separator and coagulation activator which will estimate the concentrations of creatine phosphokinase testosterone cortisol and brain-derived neurotrophic factor which will be quantified with the ELISA method The physiological determinants will be measured with the general stretching index test GSI which is calculated by the sum of the stretching in sitting standing and lying down multiplied by the body surface The level of physical fitness will be assessed with the Tecumseh step test and the VO2max with the Astrand-Rhyming test

Physical training program The study subjects will perform a physical exercise for 12 weeks divided into three blocks of 4 periods organized in 3 weeks of training plus 1 rest which simulate physical loads similar to the periods of competition used in high-performance sports The evaluations will be made prior to the training basal measurement and at the end of each of the blocks during the rest period The physical load will be organized as follows The control group CG will perform muscle strength exercises with intensities of 45 to 90 of 1RM as well as aerobic resistance with efforts of 60 to 90 of the theoretical maximum heart rate which will be controlled with a Polar brand heart rate monitor model FT7 Like the CG the experimental group EG will perform the same physical load of muscular strength and aerobic resistance in combination with specific stretching exercises

Statistical analysis Kolmogorov Smirnov test to check the normality of the data in case of presenting a normal distribution p 005 the repeated measures ANOVA test will be applied otherwise the Kruskal Wallis test will be applied The correlation level will be established with the Pearson or RhO Spearman test Factorial analysis of the relationship between variables and individuals will be applied through Hj-biplot The analysis of variables will be carried out with the SPSS v 200 program establishing a level of p 005 as the level of statistical significance

Ethical considerations The protocol was approved by the Research and Ethics in Research Committee of the State Institute of Cancerology with registration number CICC-090218-BDNFMRS-05 Financing 9476476 At the moment there are two ELISA kits for BDNF analysis and 4428676 are being managed with the Movimiento es Salud Foundation for the purchase andor maquila of the testosterone cortisol and CPK samples
