Brief Summary:
Para-athletes are submitted and intense efforts in training and competitions that often overlap in days and weeks. In this sense, and in the search for better brands and indexes, it is necessary to use recovery methods that allow less late muscle pain and better physical performance. Recovery methods are widely used in athletes of various modalities, however there are no studies that point out their effects on para-athletes. This highlights the need for studies on this topic. Paragliding athletes, who train at the Londrina Yacht Club, Londrina Canoeing and Rowing School, who present paraplegia after spinal cord injury, with motor level T10 or lower, without any problem of thermoregulation will participate in the study. All were male and female, with no complaints of musculoskeletal pain or history of upper limb muscle injuries in the last six months and with the same demand for training and competitions. Initially an evaluation will be performed where 1RM, VO2 max, pain, spasticity, body temperature, heart rate variability and electromyographic signal of the involved muscles will be tested. After three days they will be induced to fatigue through a protocol in the traction exercise and immediately directed to one of the 3 intervention groups: ice pack, immersion in cold water or rest. The same baseline evaluations will be repeated after 24, 48 and 72 hours. It is expected that the group submitted to immersion in cold water presents better parameters for pain and sports performance.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 21 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: Effect of Different Techniques of Recovery After Fadiga in Para-athletes
Estimated Study Start Date : July 25, 2020
Estimated Primary Completion Date : October 20, 2020
Estimated Study Completion Date : December 20, 2020

Arm Intervention/treatment
Experimental: Immersion in cold water
The athlete will remain submerged in a "Cryo Control - Ice Bath Systems®" bathtub, which allows filtration and maintenance of constant water temperature, and shoulder blade water (Getto and Golden, 2013) for 15 minutes in the 15 degrees Celsius (Machado et al, 2016).
Other: immersion
cold water immersion

Active Comparator: Ice pack
The athlete will remain for 20 minutes with plastic packets of 500 grams of ice each, in the region of the evaluated muscles.
Other: ice pack
ice packs through the body

Sham Comparator: Control
Group in which the athlete will be instructed to remain seated in a comfortable position, at rest, for 20 minutes.
Other: rest
seated rest

Primary Outcome Measures :
  1. evolution of muscular pain [ Time Frame: pre, immediately after, after 24, 48 and 72 hours ]
    late muscle pain will be assessed at various times to detect changes caused by fatigue will be analyzed through the threshold of pressure pain, in view of the induction of pain caused to the study, the pain will be monitored at various times

Secondary Outcome Measures :
  1. oxygen consumption [ Time Frame: pre, immediately after, after 24, 48 and 72 hours ]
    will be analyzed the percentage of maximum VO2 used for a given task by means of gas analyzer

  2. spasticity [ Time Frame: pre, immediately after, after 24, 48 and 72 hours ]
    by ashworth scale

  3. muscle recruitment [ Time Frame: pre, immediately after, after 24, 48 and 72 hours ]
    with electromyography during rowing task

  4. heart rate variability [ Time Frame: pre, immediately after, after 24, 48 and 72 hours ]
    by polar, during the paddling activity
