Functional Training group

Functional training was performed for eigth weeks. The group participated on the supervised training once a week and twice a week at home. The training was arranged in a circuit method, consisting of three to four blocks with two to three exercises each, with an execution time of two minutes and recovery of thirty seconds between exercises and one minute between each block. The exercises emphasized integrated, functional and multi-joint movements for mobility, flexibility, strength, power and muscular endurance with overload, as well as agility, speed and balance exercises.

The Motor Test Battery consisted of function and reach tests. After adding up the test scores, the individuals were classified as: "complete dependence" (0 to 6 points), "moderate autonomy" (7 to 13 points), "high autonomy" (14 to 20 points) and "total autonomy" (21 to 27 points).

The Motor Assessment Scale (Jorgensen et al., 2011) consists of six tests to assess static and proactive balance control, with the starting position being sitting on a bench, with hips and knees at 90º, without back support and feet on the floor. In each test, the testee can receive a score of 0 (does not perform the task and disqualifies the individual) or 1 (performs the task), with three possible attempts each.

To assess physical fitness through musculoskeletal capacity, the Lafayette hand dynamometer hand grip test (kgf; Lafayette hand dynamometer; United States) was used in three attempts for both sides, where the highest number achieved was validated, with the measurements measured in KGF.

A 3kg medicine ball throw test was carried out to assess the participant's muscle power. The participant had three attempts to throw the medicine ball as far as possible, with both hands at chest height. The distance, in meters (m), between the point where the ball touched the ground and the participant was measured and the lowest result of the three attempts was validated.

The Illinois Agility Test was carried out, which is used to measure multidirectional agility, both for disabled people in wheelchairs and for non-disabled people in clinical or athletic situations. To carry out the test, cones were used to mark out a pre-established route to be covered in the shortest time possible. The participant could make three attempts and the one with the shortest time, measured in seconds (s), was validated.

Arm muscle circumference was calculated using the equations proposed by Gurney and Jelliffe (1973): CMB (cm) = [Arm circumference (cm) - (π x triceps skinfold (mm))]

The measurement of total body mass was carried out with the participant in his wheelchair, using a scale of adequate dimensions, with an accuracy of 0.1 kg (ID-M300/5, Filizola, Brazil) and measurement unit in kilogram (kg). To determine the final TBM, the weight of the wheelchair was discounted.
