Title: | The time course of selected outcome measures in healthy women aged 65-74 years when varying exercise frequency and duration of an exercise walking programme | Contributor(s): | Smart, Neil (author) ; Morton, Richard H (author); Sabapathy, Surandren (author); Minahan, Clare (author); Gass, Gregory (author) | Publication Date: | 2014 | Open Access: | Yes | DOI: | 10.12715/har.2014.3.4 | Handle Link: | https://hdl.handle.net/1959.11/16725 | Open Access Link: | http://hdl.handle.net/10072/66538 | Abstract: | Background: We aimed to determine the time course of resting and exercise heart rates (HR); blood pressure (BP), changes in peak VO₂, time to exhaustion (TTE) and gas exchange threshold (Tge) at a constant weekly exercise time [120 mins] with counterbalanced variations in exercise duration (60 vs. 30min) and weekly visits (2 vs. 4 .wk⁻¹ session per week). Methods: Forty-six women aged 65-74 years were randomly assigned to 2 or 4 sessions.wk⁻¹) for six weeks. Results: Principal findings: (i) significant increase in Tge at six weeks, with no significant differences between exercise frequency or duration; (ii) no significant increase in peak values for VO₂, HR, minute ventilation and respiratory quotient after six weeks exercise training (iii) significant decreases in diastolic blood pressure (DBP) at rest and during exercise only in the 4 sessions.wk⁻¹ group and (iv) significant decrease in systolic blood pressure (SBP) during exercise and post-exercise period for both groups and rapid time course changes in HR and BP. Conclusions: Exercise elicited rapid reductions in HR and SBP during exercise and post-exercise recovery periods for both groups and there was no significant interaction between exercise duration and exercise frequency. | Publication Type: | Journal Article | Grant Details: | NHMRC/376601 | Source of Publication: | Healthy Aging Research, 3(4), p. 1-9 | Publisher: | Longdom Group SA | Place of Publication: | Belgium | ISSN: | 2261-7434 | Fields of Research (FoR) 2008: | 110602 Exercise Physiology | Fields of Research (FoR) 2020: | 420702 Exercise physiology | Socio-Economic Objective (SEO) 2008: | 920103 Cardiovascular System and Diseases | Socio-Economic Objective (SEO) 2020: | 200101 Diagnosis of human diseases and conditions | Peer Reviewed: | Yes | HERDC Category Description: | C1 Refereed Article in a Scholarly Journal |
