Physical Activity of Paraplegics Who Differ in Conditioning Level
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.11 Vol.11】
To determine maximal aerobic capacities of wheelchair dependent people, their peak oxygen uptake (Peak Vo₂) during arm cranking exercise was measured Fifty paraplegic male wheelchair basketball players (Trained) and thirty-seven untrained paraplegics (Untrained) were studied. Further more, twenty paraplegics from each group were measured for distance of wheelchair propulsion and heart rate in their daily living for a period of 24 hours. Peak Vo₂ was predicted from submaximal HR-Vo₂ relationship using age-adjusted maximal heart rate (220 beats/min-age). Distance of wheelchair propulsion was measured using Speedometers (Cateye micro cyclocomputer, Model CC-6000). Heart rate during 24 hours was measured using a portable heart rate analyzer (Vine company)
The results summarized were as follows:
1. Mean Peak Vo₂ averaged 34.2 and 23.47 ml/min/kg in trained and untrained groups, respectively. Peak Vo₂ values in trained paraplegics were significantly higher than those in untrained paraplegics. (P< 0.01)
2. No significant differences were made in distance of wheelchair propulusion between the groups.
3. No significant correlation between Peak Vo₂ (ml/kg/min) and distance in daily living was obtained with Trained nor Untrained paraplegics.
4. There were no significant differences between the two groups in total heart rate, maximal heart rate, mean heart rate and distance of wheelchair propulusion in their daily living. And Heart rate in daily life was varied from 89 to 98 beats/min, but never exceeded 100 beats/min.
5. Maximal heart rate during a basketball game ranged from 135 to 185 beats/min. And distance of wheelchair propulusion during basketball game was suit about twelve times as long as that during a normal day.
In conclusion, the data suggest that habitual physical activies do not provide sufficient circulatory stimulus to develop or maintain ideal cardiorespiratory propelling or aerobic fitness to the mobile, sedantary and incapacitated wheelchair user. Sports and recreation are considered to be more important to physically disabled individuals than able-bodied persons.
