Summary:
This is a two-group randomized clinical trial (includes an experimental and a placebo group) to verify the effects of the Myofascial Reorganization (RMF) compared to the placebo-RMF technique on running performance and thermographic, biomechanical, and viscoelastic proprieties of lower limbs of male triathletes. Data collection will be carried out one week before the first intervention session, and one week after the last intervention session. Anthropometric characteristics (height and weight), lower limbs, and biomechanical, viscoelastic, and thermographic properties will be collected before any exercise tests. After this, the athlete will be submitted to: a 10-minute protocol to verify running economy on the treadmill, followed by an incremental test on the treadmill, and a time to exhaustion test. Evaluation procedures will carried out one week before (0 weeks) and one week after (7th week) the experimental/placebo intervention. Intervention sessions will occur during six weeks, twice a week, each session lasting up to 30 minutes.

Primary Outcome Measures: Running Economy, the volume consumption of oxygen (VO2) required at a common velocity under the first lactate threshold in milliliters per minute per kilogram (mL.min-1.Kg-1)., Pre-intervention (0 week time point) and post-intervention (7 week time point)|Maximal volume consumption of oxygen, The maximal volume consumption of oxygen (VO2max) in milliliters per minute per kilogram (mL.min-1.Kg-1) will be determined as the highest value reached in the last stage plotted employing means of 15 seconds., Pre-intervention (0 week time point) and post-intervention (7 week time point)|Time to Exhaustion, Time to volitional exhaustion during the Time to Exhaustion Test, running at 100% of the last velocity reached in the incremental test, in minutes and seconds., Pre-intervention (0 week time point) and post-intervention (7 week time point)|Maximal velocity, maximal velocity derived from the incremental graded test, Pre-intervention (0 week time point) and post-intervention (7 week time point)
Secondary Outcome Measures: State of tension: F - Frequency or TONE, Frequency of natural oscillation in Hz, characterized as TONE or state of tension;, Pre-intervention (0 week time point) and post-intervention (7 week time point)|Dynamic Stiffness (N/m);, the force (in Nelton) required to deform a meter of area, Pre-intervention (0 week time point) and post-intervention (7 week time point)|D -logarithmic decrement, characterized as ELASTICITY or dissipation of the natural oscillation (arbitrary units);, Pre-intervention (0 week time point) and post-intervention (7 week time point)|R- Relaxation time, the time to relaxation after mechanical stress (ms), Pre-intervention (0 week time point) and post-intervention (7 week time point)|C - Creep, or reason between the relaxation time and the oscillation time, or Deborah number (used to characterize the fluidity of the materials in specific conditions of flux, Pre-intervention (0 week time point) and post-intervention (7 week time point)|First lactate threshold, the point in the curve where the lactate concentration per liter of blood approximates the concentration of 2 mmol/L, counting from the baseline, Pre-intervention (0 week time point) and post-intervention (7 week time point)|Second lactate threshold, determined as a point equivalent to the rise of 4 millimoles per liter (mmol/L) from the baseline, Pre-intervention (0 week time point) and post-intervention (7 week time point)
