Overview
TECAR therapy (Transfer of Energy Capacitive and Resistive) is a type of diathermy that uses radiant energy to generate endogenous heat. However, to the date there are no studies investigating the effects of TECAR therapy on exercise preconditioning and post-exercise recovery in humans. Therefore, the aim of this project is to assess the effects of different treatment protocols of TECAR therapy on. exercise preconditioning and post-exercise recovery in humans
Detailed description
Fifty male healthy volunteers will be enrolled in a randomized, double-blind (participants and assessors), controlled trial. Volunteers will be allocated in 5 groups of 10 participants each: 1 - Sham-control (fake intervention - massaging with one of the Human TECAR probes with the device turned off before or after the eccentric exercise protocol depending on randomization); 2 - Capacitive mode before exercise (preconditioning); 3 - Resistive mode before exercise (preconditioning); 4 - Capacitive mode after exercise (recovery); and 5 - Resistive mode after exercise (recovery). The treatment target will be the knee extensors muscles (quadriceps).
A standardized knee extension eccentric exercise protocol performed in the isokinetic dynamometer (Biodex System 4) will be used in order to exercise induce skeletal muscle fatigue and damage.
Volunteers will be treated with Human TECAR in a single treatment session, with 10 minutes length, that will be carried out immediately before or immediately after the exercise protocol according to the randomization.
Interventions
- Device Sham Comparator
Massaging the quadriceps with one of the Human TECAR probes with the device turned off for 10 minutes - Device Capacitive mode before
Capacitive mode applied to the quadriceps for 10 minutes - Device Resistive mode before
Resistive mode applied to the quadriceps for 10 minutes - Device Capacitive mode after
Capacitive mode applied to the quadriceps for 10 minutes - Device Resistive mode after
Resistive mode applied to the quadriceps for 10 minutes
Primary outcome measures
- Change in muscle strength [Time frame: 48 hours after eccentric exercise]
Secondary outcome measures (8)
- Change in muscle strength [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Change in CK activity [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Delayed onset muscle soreness - DOMS [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Temperature [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Muscular oxygen saturation index [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Muscular blood flow [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Muscular effort perception [Time frame: 5 minutes after the treatment, 5 minutes, 1 hour, 24 hours, 72 hours, and 96 hours after the eccentric exercise protocol]
- Participant satisfaction with the treatment [Time frame: 96 hours after the eccentric exercise protocol]
