Psychophysiological responses and running performance during treadmill and overground self-paced interval running in non-regular runners.
Masters thesis, Universiti Sains Malaysia.
Abstract
The purpose of this study is to determine the influence of different exercise setting
(treadmill vs overground) during self-paced interval running on psychophysiological
responses (feelings of pleasure and displeasure, enjoyment, heart rate responses) and
exercise performance (running speed) in non-regular runners. A total of twelve nonregular
runners (N = 12, 6 males and 6 females, mean ± SD; age 21.3 ± 1.7 years)
performed three experimental visits throughout the study with a minimum of 48 hours
gap between each visit. The first visit (pre-test measurements and familiarization) was
to measure anthropometric variables, established maximal aerobic speed (MAS) and
maximal heart rate (HRmax) and familiarization of experimental protocol. Following the
first visit, participants performed two counterbalanced exercise conditions; Treadmill
IR and Overground IR (8 repetitions x 1 minute work interval at self-selected exercise
intensity). The work intervals from each repetition interspersed with 75 seconds active
recovery. Distance covered (meter), average running speed (Km/h), variables of heart
rate, RPE, affective responses and perceived enjoyment were recorded before exercise,
every each of the work intervals and after exercise. Two-way repeated measures
ANOVA was performed to examine differences in all variables. The results showed
that there was a significant main effect of condition by interval for all the
measurements (P<0.05). Overground IR elicited greater running speed (ES = 1.06 to
2.75) and distance covered (ES= 1.73 to 3.57) compared to Treadmill IR. In regards to
the psychological data, Overground IR elicited greater FAS (ES = 0.40 to 0.67) as well
as RPE (ES = 0.56 to 0.91) compared to Treadmill IR. However, Treadmill IR elicited
greater FS (ES = 0.85 to 0.68) compared to Overground IR. In conclusion, the present
study indicates that psychophysiological and running performance to self-paced interval
running is influenced by the exercise setting (treadmill and overground).
