Recovery Kinetics Following a Soccer Training in Middle-aged Males
Recovery Kinetics Following a Soccer Training in Middle-aged Males
This study aims at investigating the recovery kinetics of skeletal muscle damage, neuromuscular fatigue and performance following a single soccer trainning session in middle aged males. 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.
Eleven male middle-aged participants will be included in this study. Participants will be initially informed about the main goals of study as well as the associated risks and benefits and then will provide their signed consent form. At baseline, they will undergo assessment of their anthropometrics (body mass, height, BMI, WHR), body compotition (using DXA), physical contition level (peak oxygen consumption, VO2peak), haemodynamic profile (diastolic and diastolic blood pressure) and daily dietary intake.Thereafter, they will participate in two experimental trials (Control trial and Soccer trial) in a randomized, crossover, repeated measure design: 1) ST (Soccer Trial): Participants in this trial will perform a soccer training session (60 min) consisted of warm-up, technical exercises and small-sided game, CT (Control Trial): Participants in this trial will only execute the evaluations daily in the dependent variables (they will not receive any intervention). Before each trial, the participants will provide a resting blood sample (for the determination of white blood cells, granulocyte cells, monocyte cells, lymphocyte cells, Hemeatocrit, Hemoglobin, red blood cells and platelets, total antioxidant capacity, glutathione and creatine kinase activity) and undergo assessments of their delay onset muscle soreness (DOMS), maximal voluntary isometric contraction (MVIC) of knee extensors and flexors (by isokinetic dynamometer), height and power of countermovement jump (CMJ-using force platform), 10m and 30m sprint time (will be evaluated using light cells). A 7-day wash-out period will apllied between ST and CT. The blood sample will be collected before and 24, 48 and 72 hours post-taining. Also, the evaluation of DOMS, MVIC, sprinting performance, power and jump height (by CMJ) will be evaluated before and 24, 48, 72 and 96 hours post training.
