|- Brief summary||Objectives: To analyze exercise intensity during a mountain time trial in handcycling and to determine predictors of race time.|
Setting: Eight Dutch rehabilitation centers and Austrian mountain.
Methods: Forty participants with spinal cord injury (SCI; high lesion level (4T6): N¼11; low lesion level (pT6): N¼29)
handcycled a 20.2-km mountain time trial. Heart rate (HR) was monitored in 17 (high: N¼5, low: N¼12) participants during the
race to determine exercise intensity, expressed relative to the heart rate reserve (%HRR). Two weeks before the race all participants
completed laboratory tests to measure anthropometrics and peak values for power output (POpeak), oxygen uptake (VO2peak) and HR.
Results: Mean race time was 4 h and 1min (s.d.: 1 h and 24min), with no difference in race time between lesion groups. Mean
exercise intensity during the race was 70±7%HRR. Exercise was mainly (73% of the race time) at a vigorous intensity
(60–89%HRR), with 29% of the total time in the 80–89%HRR zone. No clear differences were found in exercise intensities
between lesion groups. The strongest predictors for better race times were higher mean %HRR during race (R2¼57%), lower waist
circumference (R2¼39%), higher POpeak (R2¼39%) and VO2peak (R2¼32%).
Conclusion: A 20-km mountain time trial in a handcycle is intensive. Faster race times were achieved by those with a lower waist
circumference, greater fitness level and ability to perform at higher average exercise intensities during the race. Level of SCI was not
significantly associated with race time.
Purpose: Recognizing the encouraging effect of challenging events, the HandbikeBattle (HBB) was created to promote exercise among wheelchair users. The purpose of this study was to reveal the effects on physical fitness and health outcomes of four-month handbike training under free-living conditions in preparation
for the event.
Methods: In this prospective cohort study, 59 relatively inexperienced handyclists participated in the HBB of 2013 or 2014. Incremental exercise tests were conducted, respiratory function was tested and anthropometrics were measured before and after the preparation period. Main outcome measures were peak power
output (POpeak), peak oxygen uptake (VO2peak) and waist circumference, of which the changes were tested using repeated measures ANOVA. To detect possible determinants of changes in physical fitness, a linear regression analysis was conducted with personal characteristics, executed training volume and upper-extremity complaints during the training period as independent variables.
Results: POpeak, VO2peak and waist circumference improved significantly with 17%, 7% and 4.1%, respectively. None of the included variables were significant determinants for the changes in POpeak found as a result of the training.
Conclusion: A challenging event such as the HBB provokes training regimes among participants of sufficient load to realize substantial improvements in physical fitness and health outcomes.
