INTRODUCTION & AIMS
Running is common and one of the most accessible forms of exercise training, yet the suitability for adults with chronic low back pain is unknown. This study assessed the efficacy and feasibility of running in adults with chronic low back pain (LBP) and explored the relationship between training parameters and pain intensity.

METHODS
This two-arm parallel (1:1) individually randomised controlled trial allocated 40 participants (mean [SD] age: 33 [6] years, female: 50%) with non-specific chronic LBP to a 12-week intervention or waitlist control. The intervention was a progressive run-walk interval program comprising three 30-minute sessions per week, that were digitally delivered and remotely supported by an exercise physiologist. Efficacy outcomes were self-reported average and current pain intensity (100-point visual analogue scale) and disability (100-point Oswestry Disability Index). Training parameters examined were fortnightly adherence, pace and distance.

RESULTS
At 12-week follow-up, the intervention decreased average pain intensity (mean net difference [95%CI]: -15.30 [-25.33, -5.27] points, P=0.003), current pain intensity (-19.35 [32.01, -6.69] points, P=0.003) and disability (-5.20 [-10.12, -0.24] points, P=0.038), compared to control. There was no attrition and mean (SD) training adherence was 70% (20%; i.e. 2.1 of 3 sessions per week). Nine non-serious adverse events deemed potentially study-related were reported (lower limb injury/pain: n=7, cardiac syncope associated with an underlying condition: n=1, LBP: n=1). Greater fortnightly adherence (-0.04 [-0.33, 0.25] points), pace (0.23 [-0.48, 0.02] points) and distance (-0.03 [-0.13, 0.06] points) tended to be associated with greater reductions in pain intensity, yet did not reach statistical significance.

CONCLUSION
Running was feasible and improved pain intensity and disability in individuals aged 18-45 years with non-specific chronic LBP when compared to control. An individualised and conservative run-walk program should be considered a suitable form of physical activity for adults with chronic LBP.

INTRODUCTION & AIMS
A novel method for prescribing maximal aerobic speed (MAS) interval sessions involves the use of rest redistribution (RR). This approach could reduce perceived exertion and fatigue, preventing a decline in performance. This study aimed to compare acute physiological and perceptual responses between traditional (TS) and RR MAS interval training in endurance athletes.

METHODS
Twenty-five endurance runners (19 males, 6 females; age=31.9±8.5 y; maximal oxygen consumption (V̇O2max)=54.6±5.7 ml·kg·min-1; height=1.77±0.10 m; body-mass=74.0±13.0 kg) who ran &gt;5 hours/week participated. Participants completed two MAS interval sessions equal in duration (18 min total, 360 s exercise, TS=660 s rest/RR=680 s rest) in a randomised order; TS: 3 sets x 6 repetitions (1 rep=20 s running:20 s rest) at 110% MAS and RR: 18 sets x 1 repetition (20 s running:40 s rest) at 110% MAS. During both sessions V̇O2 and heart rate (HR) were measured after each repetition, and blood lactate (HLa-) measured pre-exercise and after repetitions 6, 12 and 18. Rating of perceived exertion (RPE) was measured after repetitions 6, 12, and 18, and overall session RPE 10 minutes post-session.

RESULTS
Linear mixed effects models showed that TS led to a faster increase in V̇O2 (β=.16, p=.04) and HLa- (β=.09, p&lt;.01), with consistently higher HR than RR (β=5.35, p&lt;.01). Additionally, RPE (β=1.35, p&lt;.01) and session RPE were lower in RR than TS (β=1.13, p&lt;.01).

CONCLUSION
Results indicate that when session time is similar, TS (1:1 work-to-rest ratio), produces a greater physiological stimulus with higher V̇O2, HR and HLa-. Conversely, RR (1:2 work-to-rest ratio) resulted in lower perceived exertion and metabolic stress. This makes RR an appropriate choice for training periods with lower physiological stress or during periods of fatigue management. The reduced physiological demands in RR can facilitate a more controlled and sustainable training experience while still providing valuable training benefits.

INTRODUCTION & AIMS
Adults with mental health concerns face compounded barriers to physical activity engagement. We recently conducted a randomised controlled trial to determine whether a lifestyle intervention targeting PA and nutrition was non-inferior to psychotherapy in managing depression (the CALM non-inferiority trial). While we demonstrated non-inferiority, participants assigned to the lifestyle intervention demonstrated improvements in dietary adherence and intake but not self-reported activity measures. The aim of this sub-study was to analyse actigraphy-derived measures to identify whether objective changes occurred and determine whether these were associated with mental health.

METHODS
This study included a sub-set of 36 of the 70 participants assigned to the lifestyle therapy intervention from the larger trial (ACTRN12621000387820) who were recruited based on indicative depression (Distress Questionnaire Scale 8+). A Fitbit Charge-2 measured daily steps (n), distance travelled (km), floors climbed (n) and minutes in sedentary, light, moderate and vigorous activity. Questionnaires measured psychological distress (Kessler-10), anxiety (Generalised Anxiety Disorder scale-7) and depressive symptoms (Patient Health Questionnaire-9). Linear mixed models determined within-group change over time. Spearman rank correlation coefficients examined associations between change scores over 8-weeks.

RESULTS
From baseline to 8-week follow-up, floors climbed increased 38% (mean change [95%CI]: 2.8 [0.0, 5.5], P=0.047) and minutes sedentary increased 9% (66.9 [20.8, 133.0], P=0.004). We found no change in daily steps, distance travelled, or minutes spent lightly, moderately, or vigorously active. Reducing sedentary time was associated with reduced depressive symptoms (rs=0.350, P=0.043), similarly increasing time spent in vigorous activity was associated with reduced psychological distress (rs=0.346, P=0.045).

CONCLUSION
Changes in activity were mixed, however vigorous physical activity and reduced sedentary time were associated with improved mental health in adults with psychological distress participating in a lifestyle therapy intervention for depression. Future investigations should seek to quantify minimum changes required to benefit mental health in this vulnerable population.

Published: May 2024

CASE SETTING
Gender diverse young people have lower rates of exercise, and higher rates of mental and physical health challenges, perpetuated by a lack of trans-friendly physical activity providers and environments. Our collaborative project aimed to create and support community-based exercise opportunities for trans and gender diverse young people (15-25yrs) to increase participation and improve their physical and mental health outcomes. Alongside feasibility data from 18 months delivery, two case studies will be presented (23 yrs non-binary individual, presenting with disordered eating and exercise, neurodivergence and mental illness; 18yrs transfeminine presenting with neurodivergence and participation barriers).

APPROACH AND TREATMENT
Through targeted community collaboration with young people and multidisciplinary support services, a supportive and inclusive structured exercise program was created. Specifically, we delivered and evaluated the feasibility of the exercise program for gender diverse young people; and educated the wider exercise and health community on inclusive exercise practices.

RESULTS
Forty-six gender diverse young people participated across the delivery of 11 x 8-10 week programs in 5 Perth metro locations, totalling 4518 exercise therapy hours. On average 100% of participants reported a score higher than 3/5 for program enjoyment, 79% of participants reported a score higher than 3/5 for motivation to return. Participants on average increased weekly physical activity participation by 50% since commencing the program, and 100% of participants would recommend the program to other trans peers.

REFLECTIONS/LEARNINGS
In WA, the absence of exercise opportunities for gender diverse young people prompted our tailored program. We prioritized inclusivity, safety, and participant-specific needs. Our proactive approach included health screenings, upskilling staff, and encouraging a supportive environment. Listening to participant expectations, involving a Youth Advisory Group, and engaging a Youth Engagement Officer proved vital for program success. Our reflections incorporate the significance of tailored, inclusive programs and community involvement in fostering active, safe spaces.

Published: May 2024

CASE SETTING
A Western Australia community exercise initiative supporting vulnerable youth experiencing poor mental health. Led by professionals and peers, our program offers a non-judgmental space for exercise and education, addressing discrimination, isolation, and service access barriers. Addressing a lack of physical activity options for at-risk groups, the program targets individuals affected or at risk of mental health disorders, recognizing that a quarter of youth face such challenges.

TREATMENT
An 8-week evidence-based program integrating mixed movement and education in alternative or education support settings. Tailored for at risk youth, the goal is to directly improve mental and physical health literacy, and social outcomes of participants through diverse exercise opportunities to manage and maintain thriving mental health. Specifically, we delivered and evaluated the feasibility of the program for at risk youth.

RESULTS
Since 2022, Thriving has delivered 43 8-week programs directly impacting 855 vulnerable youth in various metro (13) and regional (2) Western Australian locations, totalling 20, 860 exercise therapy hours. Forty-two collaborative partnerships and 15 staff have been involved in delivery. On average 85% of participants reported a score higher than 3/5 for program enjoyment, 80% of participants reported a score higher than 3/5 for motivation to return.

REFLECTIONS/LEARNINGS
Despite the abundance of community-based exercise and sporting organizations, a significant gap exists in their ability to address the needs of vulnerable youth, stemming from insufficient specialized skills and training. Informed by the achievements and insights of prior collaborations and projects, our program focuses on establishing inclusive activity environments for youth in low participation groups. Building on successful community relationships, we strive to encourage disengaged youth, allies, friends and families by offering tailored opportunities and pathways for meaningful exercise participation.
PERIPHERAL AND CENTRAL DEMANDS OF REPEATED-SPRINT EXERCISE WITH CONTINUOUS BLOOD FLOW RESTRICTION FOR TEAM-SPORT PLAYERS

Published: May 2024

INTRODUCTION & AIMS
Team-sport players’ repeated-sprint ability improves following repeated-sprint training with systemic hypoxia (reduced fraction of inspired oxygen) through enhanced metabolic demands compared to sea-level training. Localised hypoxia (i.e., blood flow restriction; BFR) presents a limb-specific alternative strategy, though central and peripheral demands during multiple-set repeated-sprint BFR exercise have not been quantified for team-sport players. Therefore, this study aimed to assess the impact of BFR during repeated-sprint exercise on performance, metabolic, neuromuscular, and perceptual responses for team-sport players.

METHODS
Twenty-six semi-professional and amateur team-sport players performed cycling repeated-sprint exercise (three sets of five 5-second sprints with 25 seconds of passive recovery) with continuous BFR at 45% arterial occlusion pressure or without. Power output, vastus lateralis muscle oxygenation, and cardiorespiratory responses were continuously monitored. Surface electromyography examined vastus lateralis, biceps femoris, and lateral gastrocnemius activation, and root mean square was calculated over eight consecutive cycle revolutions. Exercise-related sensations and blood lactate concentration were assessed following sets. Linear mixed models compared differences in dependent variable means between conditions and sets or repetitions.

RESULTS
Mean, peak power output, and oxygen consumption decreased (p &lt; .01) with BFR (-5.0%, -4.5%, and -6.3%, respectively) compared to without. Vastus lateralis tissue saturation index reduced (p &lt; .001) during sprints and recovery periods for BFR (-6.9% and -5.9%, respectively). Electromyography root mean square decreased (p &lt; .01) for biceps femoris and lateral gastrocnemius muscles with BFR (-2.8% and -8.9%, respectively), but remained unchanged for the vastus lateralis. Perceived limb discomfort increased (p &lt; .001) for BFR, though blood lactate concentration and rating of perceived exertion did not differ between conditions (p &gt; .05).

CONCLUSION
Repeated-sprint exercise with BFR for team-sport players reduced performance and likely increased the physiological and perceptual stimulus for the periphery with greater reliance on anaerobic glycolysis, despite comparable or decreased central demands.
EFFECT OF PRE-EXERCISE EDUCATION ON PAIN RESPONSES TO A SINGLE EXERCISE SESSION IN PEOPLE WITH KNEE OSTEOARTHRITIS: A RANDOMISED CONTROLLED TRIAL

Published: May 2024

INTRODUCTION & AIMS
In pain-free individuals, pre-exercise education about exercise-induced hypoalgesia (EIH) reduces experimental pain following a single exercise session. However, its effect in people with chronic pain remains unexplored. This study aimed to determine if EIH education influences pain during and following exercise in people with knee osteoarthritis (OA).

METHODS
Participants were randomised into an intervention group (INT) who received 15-minutes of explicit EIH education or a control group (CON) who received 15-minutes of general information about knee OA. Following education, participants’ knowledge and beliefs about exercise and pain were assessed using five questions scored on a Likert scale. Participants then undertook a single 15-minute, low-moderate intensity home-based strength exercise session delivered online. Pain was assessed on a 0-10 scale before, during, and immediately following exercise.

RESULTS
40 people with knee OA (67 ± 10.8 years old; BMI: 27.6 ± 6.5) completed the study. Education did not significantly influence participants’ knowledge or beliefs about exercise and pain. Pain reduced during exercise in both groups (mean difference [95% CI]; INT = -0.50 [-1.39 to 0.39]; CON = -1.58 [-2.55 to -0.62]), with a moderate effect (Cohen’s d) in favour of CON (-1.08 [-2.35 to 0.18], d = 0.54). Pain also reduced following exercise in both groups (INT = -0.95 [-1.77 to -0.12]; CON = -0.98 [-1.74 to -0.22]), with no difference between groups (0.03 [-1.06 to 1.12], d = 0.02).

CONCLUSION
A single exercise session reduces pain in people with knee OA, but this was not influenced by pre-exercise education about EIH. Given the chronic nature of OA pain, any intervention that can potentiate the benefits of exercise, even if marginal, may be beneficial. Therefore, further research is needed to understand if and how EIH can be modulated in people with knee OA.
FOSTERING RECOVERY: A CASE STUDY ON THE JOURNEY FROM UNCERTAINTY TO DIAGNOSIS IN POST-COVID POTS
Authors: Powrie Olivia 
Published: May 2024

CASE SETTING
Imagine, one day you are an active 20-year-old, then after a COVID-19 infection, your life is now limited by debilitating symptoms: fainting, palpitations, and exercise intolerance. Your whole world has changed, and you have no diagnosis and no treatment options. This was reality for a patient referred to cardiac rehabilitation in early 2023 as a unique case, not meeting usual service criteria.

TREATMENT
In the absence of a formal diagnosis, there was no clear pathway for treatment and no rehabilitation guidelines to follow. After a comprehensive assessment, marking the start of the road to recovery, a conservative and gradual approach to re-introducing exercise was developed, whereby progressions were only made when no symptoms were experienced during nor following the sessions. Across the next nine months, further symptoms were identified, prompting further research, which shaped a plausible diagnosis: Postural Orthostatic Tachycardia Syndrome (POTS). Whilst initially dismissed as a possibility by the patient’s cardiologist, after further questioning, gaining objective data and referral to specialist physicians, this plausible diagnosis was confirmed.

RESULTS
Through months of rehabilitation, lifestyle modifications and commencing medication, this patient has improved symptom control and increased activity tolerance. Importantly, this has allowed return to studying, return to part time work and return to tolerating daily activities.

REFLECTIONS/LEARNINGS
As exercise physiologists, we often spend more time with patients than medical practitioners, and resultingly identify characteristics which may otherwise be missed in busy clinics. This case study acts as a reminder of the importance of trusting your instinct and not being afraid to advocate for patients - doing so may just re-direct them down the road to recovery. With the increasing prevalence of dysautonomia, particularly POTS, as consequences of COVID-19 infections, there is an ever-increasing need for awareness, in addition to clinician upskilling to ensure best support and management of these patients.
SAFETY, EFFICACY, AND IMPLEMENTATION OF HOME-BASED HIGH-INTENSITY INTERVAL TRAINING FOR PATIENTS WITH CARDIAC DISEASE: A SYSTEMATIC REVIEW
Authors: Turnbull Ms Rebecca , Perera Mr Dylan , Heng Dr Hazel , Semciw Associate Professor Adam 
Published: May 2024

INTRODUCTION & AIMS
High-intensity interval training (HIIT) is safe and more effective than moderate-intensity continuous training for improving cardiorespiratory fitness in adults with cardiac disease. Home-based delivery of cardiac rehabilitation has been introduced to increase the uptake and participation of programs. The aim of this systematic review was to investigate the safety, efficacy, and implementation of home-based HIIT programs for patients with cardiac disease.

METHODS
A systematic review of the literature was conducted in three electronic databases (MEDLINE, CINAHL and EMBASE) before 2nd October 2023. Studies were included if they were written in English, peer-reviewed and compared home-based HIIT to other centre-based or home-based exercise interventions. A secondary analysis investigating intervention safety, efficacy and implementation was conducted using the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework.

RESULTS
Five studies, involving 153 participants (62 for home-based HIIT and 91 for other home-based or centre-based exercise interventions) were included in the analysis. There were no differences in functional capacity or quality of life (QOL) between home-based HIIT and other centre-based or home-based exercise interventions (p &gt; 0.05). Across all the studies, the reporting rates were highest for program effectiveness (75%) and adoption (75%), followed by reach (70%), implementation (40%), and maintenance (10%). Adverse events were reported during the home-based HIIT intervention in two studies (3%). Participant attrition within home-based HIIT interventions was 8-12%. In studies where adherence to the home-based HIIT protocol was reported, this ranged between 36% and 85%.

CONCLUSIONS
Home-based HIIT resulted in similar effects in functional capacity and QOL as other centre-based and home-based exercise interventions for patients with cardiac disease. HIIT in the home appears to be safe and effective, however adherence to the protocol varies. Further high-quality studies are needed to inform best practices for prescribing HIIT in the home.

INTRODUCTION & AIMS
Improving aerobic fitness in people with multiple sclerosis (MS) can reduce fatigue, and lower the risk of cardiovascular disease. Aerobic training can be challenging due to paresis, access to suitable equipment and fatigue. The aim was to investigate whether functional electrical stimulation (FES) cycling combined with arm crank interval exercise (hybrid FES interval training) is feasible for people with advanced MS, and its effects on aerobic fitness and fatigue.

METHODS
Hybrid FES interval training was performed 2 d/wk for 12 weeks. Each session consisted of 40 minutes of continuous FES cycling with arm crank intervals of 30 seconds work/30 seconds rest added concurrently for 20 minutes. The intensity target was a minimum of 60% of arm crank power and ‘hard’ measured by rate of perceived exertion (RPE) on a scale of 6-20. Feasibility was measured by attendance, compliance to intensity and time targets, adverse events, and drop outs. Aerobic fitness was assessed by an arm crank maximal test. Fatigue was measured via the Modified Fatigue Impact Scale (MFIS).

RESULTS
Seven participants (6 female; age 57.1±7.8y; Expanded Disability Status Scale 7.1±0.8) with advanced MS attended 80±10.4% of the scheduled sessions and there were no adverse events or drop outs. Average RPE at the end of each training session was 15±2, representing vigorous intensity exercise. Aerobic fitness did not change pre- to post-intervention [14.2±5.7 to 14.78±6.0 mL/kg/min (p=0.43)]. There was a trend towards a reduction in the MFIS score pre- to post-intervention [31.0±10.4 to 21.7±11.4 (p=0.10)].

CONCLUSION
Hybrid FES interval training is feasible for people with advanced MS who need exercise equipment appropriate for their condition, and can represent vigorous intensity exercise. The positive findings support the need for future randomized control trials that can assess the aerobic fitness changes and associated health benefits of hybrid FES interval training.
