The participants will perform a soccer training session \[A single training session including 60 minutes of warm up, soccer technical exercises and small-sided game\] and a cotrol trial (No intervention included, only daily measurements) in randomized, repeated measures, crossover design. Assesesments related to skeletal muscle damage, performance and neuromuscular fatigue will be executed before the training session and daily for four consecutive days after training., conditionsModule conditions: Skeletal Muscle Damage, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: CROSSOVER, primaryPurpose: OTHER, maskingInfo masking: NONE, enrollmentInfo count: 11, type: ESTIMATED, armsInterventionsModule interventions name: ST, outcomesModule primaryOutcomes measure: Change in White blood cell count, primaryOutcomes measure: Change in Granulocyte cell count, primaryOutcomes measure: Change in Platelets cell count, primaryOutcomes measure: Change in Monocyte cell count, primaryOutcomes measure: Change in Lymphocyte cell count, primaryOutcomes measure: Change in percentage of Hematocrit level, primaryOutcomes measure: Change Red blood cells count, primaryOutcomes measure: Change in Hemoglobin level, primaryOutcomes measure: Change in Creatine kinase activity, primaryOutcomes measure: Change in Total antioxidant capacity, primaryOutcomes measure: Change in Glutathione concentration in blood, primaryOutcomes measure: Change in countermovement jump height, primaryOutcomes measure: Change in Peak power during coutermovement jump test, primaryOutcomes measure: Change in isometric peak torque of knee extensors and flexors, primaryOutcomes measure: Change in sprint time of 10 m, primaryOutcomes measure: Change in sprint time of 30 m, primaryOutcomes measure: Change in delayed onset of muscle soreness, secondaryOutcomes measure: Dietary intake, secondaryOutcomes measure: Peak Maximal oxygen consumption (Peak VO2), secondaryOutcomes measure: Body Mass, secondaryOutcomes measure: Body Height, secondaryOutcomes measure: Body Fat, secondaryOutcomes measure: Lean body mass, secondaryOutcomes measure: Bone mass density, secondaryOutcomes measure: Bone mass content, secondaryOutcomes measure: Field activity during the soccer training, secondaryOutcomes measure: Heart rate during the soccer training, secondaryOutcomes measure: Systolic Blood Pressure, secondaryOutcomes measure: Dystolic Blood Pressure, secondaryOutcomes measure: Rest Heart Rate, eligibilityModule sex: MALE, minimumAge: 40 Years, maximumAge: 60 Years, stdAges: ADULT, contactsLocationsModule locations facility: University o Thessaly, School of Physical Education and Sports Science, status: RECRUITING, city: Tríkala, zip: 42100, country: Greece, contacts name: Athanasios Z Jamurtas, Prof, role: CONTACT, phone: +30 24310 47054, email: ajamurt@pe.uth.gr, contacts name: Ioannis G Fatouros, Prof, role: CONTACT, phone: +30 24310 47047, email: ifatouros@pe.uth.gr, contacts name: Athanasios S Poulios, PhD, role: PRINCIPAL_INVESTIGATOR, geoPoint lat: 39.55493, lon: 21.76837, hasResults: False
