简要总结
This study aims to evaluate the potential benefits of Monopolar Capacitive Resistive Radio-frequency (448 kHz) on the sports performance of Paralympic swimmers.
详细描述
A randomized, double-blind, crossover, controlled and sham-controlled clinical trial
Evaluate the effectiveness of resistive capacitive diathermy as sports performance enhancement of Paralympic elite swimmers compared with a "sham" diathermy treatment and with a control group. The resistive capacitive diathermy is a medical device supplying low (448 kHz) radiofrequency with a maximum output power of 200 W, used to improve physiological aspects and theoretically allowing improvement in swimming performance. The sham diathermy treatment is administered with the device set on "on" but not active (not supplying energy) and control group will not receive anything, randomly assigned to either resistive capacitive diathermy treatment (group 1), sham-treatment (group 2) or control (group 3) athletes are submitted to a twenty minutes session prior swimming performance. The main outcome measures are the simulate swimming time trial (seconds) to assess time completing the presented course and Borg Scale for perceived exertion. Outcome measures are administered at completing each time trial.

结局指标
主要结局
Time-trials (Experimental Group)
时间窗: through study completion, an average of 4 months
Time in Seconds that takes the athlete since taking off from the edge of the pool until reaching two different distances, 50 and 100 meters, measuring each distance twice, time will be measure by technical digital chronometer.
Change of Perceived exertion (Placebo group)
时间窗: through study completion, an average of 4 months
To measure the athlete's qualification of their exertion the Borg Rate of Perceived Exertion (RPE) Scale® will be used, previously validated and with the proper license, measures will be taken pre/post-competition.
Change of Perceived exertion (Experimental Group)
时间窗: through study completion, an average of 4 months
To measure the athlete's qualification of their exertion the Borg Rate of Perceived Exertion (RPE) Scale® will be used, previously validated and with the proper license, measures will be taken pre/post-competition.
Change of Perceived exertion (Sham group)
时间窗: through study completion, an average of 4 months
