Abstract

Recent studies at the University of Cape Town found comparable physiological and metabolic responses between the elliptical trainer, stepper, and treadmill, and a decrease in muscular effort of lower extremity muscles when exercising at similar intensities on the elliptical trainer and stepper in comparison to treadmill running. It was therefore suggested that the elliptical trainer and stepper could be useful substitutes for running when periods of reduced running load are required, such as during rehabilitation from an injury, or as a means to increase running load without the risk for increased injury. It remains unknown whether the elliptical trainer can be used to improve running performance, and thereby maintain cardiovascular fitness, if added to a running training programme. Thus, the purpose of this study is to investigate whether supplementing existing running training with elliptical training enhances running performance in trained runners. The study was conducted at the Sport Science Institute of South Africa (SSISA). Thirteen trained runners were recruited (male/female: N=11/2, age: 32.8 ± 8.3) to complete PRE and POST assessments of peak treadmill running speed (PTRS), 8-km time trial, and body composition, with assessments of PTRS, 8-km time trial, RPE, and HRmax. Between PRE and POST assessments, participants took part in an 8-week intervention of either additional running, or the same additional training load on the elliptical trainer. Results indicate a significant difference between PRE and POST PTRS as runners increased their peak running speed following the training intervention by 0.4km/h [18.5 ± 1.5 and 18.9 ± 1.5 PRE and POST, respectively] for all participants combined. However, no difference was found between the elliptical training and running training groups. Eightkm time trial, RPE, and HRmax were unchanged. These findings support expectations that the elliptical trainer can be used as a useful modality to both increase running performance and maintain fitness levels when unable to run.
