Summary:
This study aims at investigating the energy expenditure following a single Football 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.

Primary Outcome Measures: Change in exercise-induced energy expenditure, Exercise energy expenditure (kcal) will be measured using a portable indirect calorimetry system, At pre-exercise, during, and post-exercise session (single bout lasting 60 minutes)|Change in excess post-exercise oxygen consumption (EPOC), EPOC (kcal) will be measured using a portable indirect calorimetry system, At post-exercise session (single bout lasting 60 minutes)|Change in blood lactate concentration (BLa), BLa (mmol/L) concentration will be measured in a microphotometer with commercially available kits., At pre- and post-exercise session (single bout) at 3 minutes post-exercise|Change in heart rate, Heart rate (bpm) will be measured with a wearable heart rate monitor, At pre-exercise, during, and post-exercise session (single bout lasting 60 minutes)|Change in perceived exertion, Rating of perceived exertion (RPE) will be measured with the Borg scale (0-10), At pre-exercise and post-exercise session (single bout lasting 60 minutes)|Respiratory Exchange Ratio (RER), Respiratory Exchange Ratio (RER) will be measured using a portable indirect calorimetry system, At pre-exercise, during, and post-exercise session (single bout lasting 60 minutes)|Breath Frequency (BF), Breath Frequency (BF) will be measured using a portable indirect calorimetry system, At pre-exercise, during, and post-exercise session (single bout lasting 60 minutes)
Secondary Outcome Measures: Body weight, Body weight will be measured on a beam balance with stadiometer, At baseline|Body height, Body height will be measured on a beam balance with stadiometer, At baseline|Body mass index (BMI), BMI will be calculated using the Quetelet's equation, At baseline|Waist circumference (WC), WC (cm) will be measured using a Gullick II tape, At baseline|Hip circumference (HC), HC (cm) will be measured using a Gullick II tape, At baseline|Waist-to-hip ratio (WHR), WHR will be calculated by dividing the waist by the hip measurement, At baseline|Resting metabolic rate (RMR), RMR (kcal) will be measured using a portable open-circuit indirect calorimeter with a ventilated hood system, At baseline|Body fat (BF), Body fat (%) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA), At baseline|Fat mass (FM), FM (kg) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA), At baseline|Fat-free mass (FFM), FFM (kg) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA), At baseline|Bone mass density, Bone mass density will be measured by using Dual-emission X-ray absorptiometry, At baseline|Bone mass content, Bone mass content will be measured by using Dual-emission X-ray absorptiometry, At baseline|Peak Maximal oxygen consumption (Peak VO2), Peak VO2 will be estimated by open circuit spirometry via breath by breath method, At baseline|Dietary intake, Dietary intake will be assesed over a 7-day period using diet recalls, At baseline|Field activity during the soccer training, The field activity will be continuously monitored during the soccer training using global positioning system (GPS), [Time Frame: During the 60 minutes soccer training (ST) session (72 hours after baseline measurements)|Systolic Blood Pressure, Systolic Blood Pressure will be examined using sphygmomanometer, At baseline|Dystolic Blood Pressure, Dystolic Blood Pressure will be examined using sphygmomanometer, At baseline|Rest Heart Rate, The rest heart rate will be estimated using a heart rate monitor, At baseline
