简要总结
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.
详细描述
1. This study was approved by the Ethical Committee involving Research with Human Beings of the University of Santa Catarina (UDESC) under protocol number 56498722.1.0000.0118. Consolidated Standards of Reporting Trials will be followed.
2.1 General objectives: to verify the effects of the Myofascial Reorganization (RMF) technique compared to the placebo-RMF technique on running performance and thermographic, biomechanical, and viscoelastic proprieties of lower limbs of athletes.
2.2 Specific objectives: intragroup and intergroup comparisons of running-related performance variables, lower limb skin temperature, and biomechanical and viscoelastic properties.
3. Sample: Athletes volunteers living in Florianópolis, SC, Brazil, if they meet inclusion criteria and do not meet exclusion criteria.
4. Sampling: will be non-probabilistic by convenience and snowball (participants will be recruited by social media, flyers, and by referral of other participants).

盲法说明
Participants will be blinded to which group they will belong, as they never had contact to the technique investigated. The statistical analysis will be blinded as well, and the statistical will not know which is the experimental or the placebo group.

结局指标
主要结局
Maximal velocity
时间窗: Pre-intervention (0 week time point) and post-intervention (7 week time point)
maximal velocity derived from the incremental graded test
Running Economy
时间窗: Pre-intervention (0 week time point) and post-intervention (7 week time point)
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).
Time to Exhaustion
时间窗: Pre-intervention (0 week time point) and post-intervention (7 week time point)
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.
Maximal volume consumption of oxygen
时间窗: Pre-intervention (0 week time point) and post-intervention (7 week time point)
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.
