Is Home-Based, High-Intensity Interval Training Cycling Feasible And Safe For Patients With Knee Osteoarthritis? Study Protocol For A Randomized Pilot Study, Justin W L Keogh, Josephine Grigg, Christopher J Vertullo

Justin Keogh

BACKGROUND:

Osteoarthritis (OA) is a degenerative joint disease affecting the knee joint of many middle-aged and older adults. As OA symptoms typically involve knee pain and stiffness, individuals with knee OA are often insufficiently physically active, have low levels of physical function, and are at increased risk of other comorbidities and reduced quality of life. While moderate-intensity continuous training (MICT) cycling is often recommended, little is known about the feasibility, safety, and benefits of high-intensity interval training (HIIT) cycling for this population, even though the feasibility, safety, and benefits of HIIT have been demonstrated in other chronic disease groups.

Sedentary Behavior And Related Factors Among Full-Time, University Faculty, Anna Greer, Mary Keenan

Anna E. Greer

Purpose– Sedentary behavior, independent of physical activity, is a risk factor for both morbidity and mortality. Little is known about factors related to sedentary behavior. The purpose of this paper is to examine the relationship between sedentary behavior and the demographic characteristics, perceived physical activity (PA) environment, and PA behaviors of 72 full-time, university faculty members. Design/methodology/approach– For this cross-sectional study, data were collected online using Survey Monkey®. Findings– Participants spent an average of 473 and 328 minutes/weekend day in sedentary activity. There was a positive correlation between minutes spent in vigorous PA and minutes spent sedentary while watching TV …

Acute Exercise And Gastric Emptying: A Meta-Analysis And Implications For Appetite Control, Katy Horner, Matthew Schubert, Ben Desbrow, Nuala Byrne, Neil King

Nuala Byrne

Background: Gastric emptying (GE) could influence exercise-induced changes in appetite and energy intake. GE also could contribute tochanges in gastric symptoms and the availability of nutrients during exercise, which will subsequently affect performance. Objective: The objective of this review was to determine the effects of acute exercise on GE using a systematic review and meta-analysis. The most common parameters to determine GE were selected, consisting of half-emptying time and volume emptied. Oral-caecal transit time (OCTT) was also examined. Data Sources: Research databases (PubMed, Scopus, Google Scholar, EBSCOhost, SPORTDiscus) were searched through November 2013 for original studies, abstracts, theses and dissertations …

The Effect Of Low-Volume, High-Intensity Interval Training On Blood Glucose Markers, Anthropometric Measurements, And Cardiorespiratory Fitness In Patients With Type Ii Diabetes., Sujoy Bose

Sujoy Bose

The profound biologic, & societal burden of the syndrome of Diabetes Mellitus (DM) is subject of numerous ongoing research. There is significant interest in non-pharmacologic glycemic control, principally by exercise. While beneficial effects of generic exercise on glucose metabolism have been well established in literature, there is a paucity of research on the volume, intensity, & type of the most optimal forms of exercise that affect glycemic physiology in those with type II DM. The goal of this study was to perform a systematic review of the impact of high intensity interval training (HIIT) on glycemic control in people with …

Controlling Balance Decline Across The Menopause Using A Balance-Strategy Training Program: A Randomized, Controlled Trial, S. Fu, Nancy Low Choy, Jennifer Nitz

Nancy Low Choy

Objective: To evaluate effectiveness and long-term benefits of a specific balance-strategy training program in sedentary women aged 40-60 years and whether participation leads to adoption of a more active lifestyle. Method: Fifty healthy women were admitted to the randomized, controlled trial on the basis of their activity level. Subjects were randomly assigned to an intervention or control group, with the former attending twice-weekly for 12 weeks. Assessments made pre- and post-intervention and at 9 months follow-up included: personal demographics, hormone replacement therapy medication, activity level, balance measures, somatosensory function, ankle flexibility and leg muscle strength. Results: The intervention group showed …

The Efficacy Of A Balance Strategy Training Circuit For Community Based Elders Who Have Had A Fall, Jennifer Nitz, Nancy Low Choy

Nancy Low Choy

Background:
Older people participate in exercise programmes to reduce the risk of falls but no study has investigated a specific balance strategy training intervention presented in a workstation format for small groups.

Objective:
To determine whether a specific balance strategy training programmeme delivered in a workstation format was superior to a community based exercise class programme for reducing falls.

Design:
A randomised controlled trial model.

Setting:
Neurological Disorders, Ageing and Balance Clinic, Department of Physiotherapy, The University of Queensland.

Subjects:
73 males and females over 60 years, living independently in the community and who had fallen in the previous year …
