INNOVATIONS

RESULTS DISCUSSION MOTIVATION

• Technological innovations in wheelchair ergometers

– Replicate the biomechanical aspects of propulsion in manual wheelchair

– Assessment the physiological response of specific sport paralympic

Page 5: PARALYMPIC TECHNOLOGY

PURPOSE METHOD CONCLUSIONRESULTS DISCUSSION MOTIVATION

Evaluate the power parameters and fatigue

index of paralympic wheelchair athletes using

the Wingate test in a new wheelchair ergometer.

Page 6: PARALYMPIC TECHNOLOGY

PURPOSE METHOD CONCLUSION

• A new wheelchair ergometer prototype was developed to apply anaerobic tests

• Structural parts were designed with anthropometric measurements and manufactured

in two modules (propulsion and electromagnetic resistance)

• 12 Paralympic athletes users of wheelchair

– 4 Wheelchair Basketball, 4 swimming, 4 weightlifting

– Gender - 9 males and 3 females;

– Age – 27.9 ± 11.1 years;

– Injury time – 13.5 ± 9.9 years;

– Body mass – 69.0 ± 21 kg.

• Injury of wheelchair athletes: 6 spinal cord injured; 1 poliomyelitis, 1

myelomeningocele, 1 congenital malformation of the lower limb, 1

epiphysiolysis in lower limb, 2 with lower limb ampute.

NEW FATIGUE INDEX

Page 16: PARALYMPIC TECHNOLOGY

PURPOSE METHOD CONCLUSIONRESULTS DISCUSSION MOTIVATION

• Studies report factors to be considered:

– Specificity of each paralympic sport

– Gender

– Level of injury

(Devillard, 2001)

Page 17: PARALYMPIC TECHNOLOGY

PURPOSE METHOD CONCLUSIONRESULTS DISCUSSIONMOTIVATION

- Using the new wheelchair ergometer prototype

were found absolute power and a new energy

fatigue index parameters;

- The parameters studied to the sample was

related to functionality, gender, level of injury and

the specific paralympic sports.
