Effects of Diathermy Application on Immediate Sports Performance of Paralympic Swimmers

February 8, 2021 updated by: Universidad Complutense de Madrid
This study aims to evaluate the potential benefits of Monopolar Capacitive Resistive Radio-frequency (448 kHz) on the sports performance of Paralympic swimmers.

Study Overview

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Radio-frequency group
The equipment used, INDIBA® Activ Ct9, (448kHz), with the switch-mode on.
Intervention is conducted using a 65-mm diameter Resistive (RES) electrode (movable), and a planar electrode was used as a return electrode on the abdomen. The electricity is administered in the following manner: cream was applied to the upper limbs existent area, and the electrical output is marked at 75% by moving the movable electrode and if not tolerated by the patient lowered until 35%, Therapy is conducted for 20 minutes, prior swimming time trials.
Placebo Comparator: Placebo group
The equipment used, INDIBA® Activ Ct9, (448kHz), with the switch-mode off.
Placebo is conducted using a 65-mm diameter RES electrode (movable), and a planar electrode was used as a return electrode on the abdomen. The electricity IS NOT administered, the cream was applied to the upper limbs existent area and moving the movable electrode, intervention is conducted for 20 minutes, prior to swimming time trials.
Sham Comparator: Control Group
NO INTERVENTION athlete's usual pre-competition warming-up
This group will warm-up as they usually do in competitions, for later time trial measuring.
