Item Compensation in movement behaviours following exercise of different intensities in older adults(2019-08-01) Goncin, Nikola; Dogra, ShilpaThe overall purpose of this thesis was to assess compensation in movement behaviours of older adults following exercise. Participants (n=28, 69.7±6.5 years) completed the following exercise protocols in random order, one week apart: moderate continuous exercise (MOD), high intensity interval exercise (HI), and sprint interval exercise (SPRT). A thigh-worn device (ActivPALTM) was used to measure movement behaviours at baseline (two weeks prior to exercise), day zero (the day of exercise), and the subsequent three days. Overall, compensation was observed in all movement behaviours but sleep. It appears that the greatest compensation occurred following SPRT, with increases in ST and decreases in LPA and MVPA. Fatigue could explain this compensation. Higher intensity exercise appears to have a more profound effect on future movement behaviour patterns than moderate intensity. This has important implications for prescribing high intensity exercises in older adults as it may increase ST, decrease LPA and displace current MVPA.Item Physiological responses to pedal-assist e-bike use in older adults(2021-12-01) Jenkins, Michael; Dogra, ShilpaPedal-assist electric bicycles (pedelecs) have been found to elicit moderate-to-vigorous intensity physical activity (MVPA) in younger adults, however, it is unknown if pedelec riding elicits MVPA in older adults or if loading the pedelec changes the level of e-assist used, and thus the intensity of the activity completed. Participants (n=21, mean age 70.1 ± 5.1) completed a maximal exercise test followed by two 6.25km outdoor pedelec rides at a self-selected comfortable pace, once with 20kg of load added and once without, in random order. Nearly all participants (19/21) achieved a mean intensity of MVPA. Mean intensity from unloaded and loaded rides was 76% HRmax and 75% HRmax, respectively. No differences were observed when comparing HRavg, HRpeak, POavg or POpeak between unloaded and loaded pedelec rides. Older adults self-select at least MVPA while riding pedelecs on a closed course. The added load did not change the intensity of pedelec riding.
