Published: May 2024

INTRODUCTION & AIMS
Implementing resistance training (RT) for athletes may be difficult during some training-phases due to competing demands. However, it is currently unknown how strength and conditioning coaches prescribe RT during periods of planned de-loading. Therefore, we aimed to investigate the RT prescription practices of coaches during four common de-loading periods (taper, competitive season, tournament, travel).

METHODS
An anonymous online survey was shared globally to coaches, with data analysed from 204 responders (current level of athlete coached: world class n=68, elite/international n=62, highly-trained n=64, trained n=10). Coaches only provided answers about prescription for de-loading periods which they reported encountering. Where a coach indicated not prescribing RT for specific de-loading periods, they provided information on any barriers preventing RT prescription.

RESULTS
Weekly RT prescription across all de-load periods was typically reported as: 1-2 sessions, 30-60 min, 1-3 sets, 1-6 repetitions. Most coaches reported decreasing volume during all periods (taper: 89.1%, competitive season: 70.4%, tournament: 84.1%, travel: 74.6%), with the most common reduction in RT volume reported as 0-25%. Most coaches also decreased intensity during a taper (52.9%), tournament (54.8%) and travel (53.6%), with a 0-25% reduction most common. ‘Lack of equipment and facilities’ and ‘scheduling/time’ were common barriers cited to RT prescription during the competitive season (100% for scheduling/time), tournament (55.6% and 50.0%), and travel (57.3% and 60.0%). During a taper, ‘recovery’ was the most reported reason (41.7%).

CONCLUSION
During planned de-loading periods, both training volume and intensity are generally decreased by coaches compared to periods of normal training. The similarity of barriers to RT prescription during de-load periods suggests the experiences of coaches are not influenced by the phase. To address barriers experienced by some coaches, researchers should examine the use of alternative RT strategies for periods of planned de-loading to maintain training stimulus.
SOLVING THE HIGH-INTENSITY MUTLIMODAL TRAINING PRESCRIPTION PUZZLE: A SYSTEMATIC MAPPING REVIEW

Published: May 2024

INTRODUCTION & AIMS
High-Intensity Multimodal Training (HIMT) refers to all styles of high-intensity combined aerobic, resistance and/or bodyweight exercise. Previous heterogeneity in exercise prescription and reporting in HIMT reduces the understanding of which factors should be commonly considered when prescribing HIMT (e.g., exercise volume, intensity, duration). Previous studies have demonstrated positive effects of HIMT on health and performance outcomes. However, methodological disparities limit comparisons between findings. This systematic mapping review examines the prescriptive considerations and health and performance outcomes of HIMT in the context of training.

METHODS
A systematic literature search was conducted using Ovid Medline, SPORTDiscus and Cochrane Library databases and additional sources to identify studies up until February 2023. A total of 37090 records were retrieved, of which 221 were included for review. 247 individual HIMT protocols were included for categorical analysis against the Consensus on Exercise Reporting Template (CERT) and Applied Research Model for the Sport Sciences.

RESULTS
A total of 85 unique terms were used to describe HIMT. Included studies most commonly prescribed HIMT using a consistent exercise selection and circuit format. Exercise intensity was inconsistently reported on and a large proportion of studies incorrectly prescribed ‘high-intensity’ exercise according to ACSM definitions (i.e., &lt;77% HRmax). Participation location, supervision and participation format were the most commonly reported non-training variables. The most frequently reported outcomes were cardiovascular health, perceptual outcomes, body composition and biochemical outcomes. A large proportion of previous HIMT research was experimental in design.

CONCLUSIONS
Previous HIMT research demonstrates a lack of standardisation in reporting. Future studies should seek to follow guidelines such as the CERT to improve reporting rigour. Additionally, forthcoming research should attempt to actively involve practitioners in implementation studies to improve ecological validity among interventions.

Published: May 2024

INTRODUCTION
Running economy (RE) is the strongest predictor of long-distance running performance in well-trained athletes (1). Carbon-plated running shoes have indicated improvements of 4% in RE when compared to previous generation non-carbon-plated running shoes (2). However, these studies have key methodological limitations; the prescribed intensities didn’t replicate race demands, the influence of fatigue was not considered, and testing was only completed on males. AIM: The primary aim of this study was to develop an appropriate protocol to measure RE in female long-distance runners. The secondary aim was to compare performance and RE of two carbon-plated performance shoes in female long-distance runners.

METHODS
Seven female endurance athletes (age: 30.7 ± 6.6 y, mass: 59.1 ± 5 kg, VO2max: 55.3 ± 4.1 ml/kg/min) completed a graded exercise test to establish a relative race intensity (90% of lactate threshold). Participants completed two testing sessions during the follicular phase of the menstrual cycle in alternating footwear, which consisted of four 7-minute trials, a 25-minute continuous run, four 7-minute trials, and a 13-minute distance trial. RE was recorded as the oxygen consumption and energetic cost of running from minutes 5-7 of each trial. Shoe preference was recorded midway through the first session and the end of the second session. A linear mixed model was used to compare economy and performance metrics.

RESULTS
There was no significant difference in RE because of fatigue and no significant difference between shoes. However, large individual variations were evident. Participants reported disagreement between preferred shoe and the shoe that demonstrated greatest RE.

CONCLUSION
A longer protocol that controlled for the menstrual cycle did not induce fatigue related changes in female participants, supporting a higher resistance to fatigue in females (3). The individual variation between shoes suggests that further analyses should be conducted to inform shoe selection for female long-distance runners.

INTRODUCTION & AIMS
Heat acclimation (HA) is critical to mitigate the adverse effects of heat on exercise performance. While these methods yield physiological adaptations to heat, it also results in greater internal training load. This can potentially compromise training quality and lead to overreaching. Therefore, there is a need for HA protocols that address situations where training quality is crucial, yet the heat stimulus is necessary. The aim of this study was to investigate the influence of shorter, more frequent rest breaks with per-cooling (PerC) as an alternative HA session on physiological, perceptual, and self-paced maximal cycling performance, compared to continuous heat exposure.

METHODS
Thirteen participants completed one continuous and three intermittent heat exposure (IHE) maximal self-paced cycling protocols matched for total exercise and rest duration, in a random order in heat (36°C, 80% relative humidity): 1 x 60-min exercise (CON), 3 x 20-min exercise with 7.5-min rest between sets (IHE-20), 4 x 15-min exercise with 5-min rest between sets (IHE-15), 6 x 10-min exercise with 3-min rest between sets (IHE-10). Mixed-method PerC (crushed-ice ingestion and cooling vest) was applied during rest periods of all IHE protocols.

RESULTS
Total distance completed was greater in IHE-10, IHE-15, and IHE-20 compared to CON (+11%, +9%, and +8%, respectively), with no difference observed between IHE protocols. Total time spent above 38.5°C core temperature (Tc) was longer in CON compared to IHE-15 and IHE-20 (+62% and +78%, respectively), but similar to IHE-10 (+5%). Furthermore, a longer time above 38.5°C Tc occurred in IHE-10 versus IHE-15 and IHE-20 (+54% and +69%, respectively). Sweat loss did not differ between conditions.

CONCLUSION
Intermittent heat exposure with PerC may be a viable alternative HA protocol in situations where training quality takes precedence over thermal stimulus, or when both factors hold equal priority.

Published: May 2024

INTRODUCTION & AIMS
The cardiac and macrovascular system is vital for human exercise capacity, yet the microvascular network is primarily responsible for delivering nutrients and oxygen to metabolically active tissues like skeletal muscle. Due to methodological limitations, few studies have investigated the role of muscle microvascular blood flow in determining exercise capacity or intolerance in individuals with chronic conditions such as type 2 diabetes. Our aim was to use modern contrast-enhanced ultrasound to directly measure microvascular blood flow in skeletal muscle at rest and after a maximal treadmill exercise test in individuals with controlled type 2 diabetes.

METHODS
Fifteen adults with controlled type 2 diabetes (age: 62.5 ± 8.0 years [M ± SD]; BMI: 31.6 ± 6.9 kg/m2; HbA1c: 6.7 ± 0.9%; 13 females and 2 male) attended the laboratory after a 2-hour fast and completed a Modified Bruce treadmill exercise test until exhaustion. Microvascular blood velocity, volume, and flow in the vastus lateralis muscle was assessed at rest, immediately post-exercise, and 30 minutes post-exercise via contrast-enhanced ultrasound during a constant-rate intravenous contrast agent infusion (DEFINITY®). Participants also completed a whole-body dual x-ray absorptiometry scan and a six-minute walk test (6MWT).

RESULTS
Microvascular blood velocity, volume, and flow increased immediately after exercise (∼230%, ∼79%, and ∼529%, respectively; all p&lt;0.001), and remained elevated above baseline levels 30 minutes post-exercise (∼79%, ∼25%, and ∼139%, respectively; all p≤0.003). Resting and post-exercise skeletal muscle microvascular blood flow measures were not associated with VO2peak (ml/min/kg), time to exhaustion, or six-minute walk distance (all p&gt;0.05).

CONCLUSION
Muscle microvascular blood flow remains elevated for up to 30 minutes following maximal aerobic exercise in individuals with controlled type 2 diabetes. The lack of association between muscle microvascular blood flow and exercise capacity is not clear but may indicate considerable blood flow redundancy or reserve within the vascular network.

Published: May 2024

BACKGROUND
Exercise is widely accepted as a first-line treatment for chronic non-specific low back pain (CNSLBP). However, the benefits of exercise diminish over time, as does adherence to exercise. It is unclear whether greater exercise adherence is associated with improvements in pain intensity (PI) and functional limitation (FL). We explored the relationship between exercise adherence and patient-reported outcomes in people with CNSLBP.

METHODS
We conducted a secondary analysis of the Cochrane systematic review, ‘Exercise therapy for chronic low back pain’, using a subset of 24 trials that measured exercise adherence compared to usual care. Random-effects meta-analysis was performed in R for PI and FL at the closest time point post-intervention. We used predefined subgroups of exercise adherence of ‘Good’ (90-100%), ‘Moderate’ (70-89%), or ‘Poor’ (14-69%) adherence. We used the risk of bias judgements provided by Cochrane.

RESULTS
All trials included were deemed low risk of bias. Compared to usual care, ‘Good’ adherence was associated with reduced PI by 17.83 points on a 100-point scale (95% CI -26.23 to -9.43; I2 = 81.7%) and FL by 9.69 points on a 100-point scale (95% CI -12.64 to -6.74; I2 = 18.9%). ‘Moderate’ adherence was associated with reduced PI by 6.93 points (95% CI -10.43 to -3.44; I2 = 18.3%) and FL by 3.80 points (95% CI -6.10 to -1.49; I2 = 0%). ‘Low’ adherence was associated with reduced PI by 7.50 points (95% CI -19.83 to -4.84; I2 = 89.7%) and FL by 3.35 points (95% CI -10.45 to -3.74; I2 = 82.7%).

CONCLUSIONS
Greater adherence to exercise is associated with greater improvements in PI and FL in adults with CNSLBP. Further research is needed to understand the causal effect of adherence on patient-reported outcomes. Better reporting of this potentially important exercise parameter in randomised trials is also needed.
IN-HOME COMMUNITY AGED CARE FALLS PREVENTION TELEHEALTH PILOT
Authors: Street Richelle , Anderson Jane 
Published: May 2024

BACKGROUND
A small scale pilot was conducted to test the concept of a remotely delivered in-home prescriptive exercise program for older Australians at risk of falling or with a history of falls. There is limited evidence for the efficacy of remotely delivered falls prevention programs within the aged community setting. Most community models are in-person and resource poor. This can result in older Australians living in isolated locations not having access to a service or provision of a service that cannot support the intervention intensity to produce effective functional gains. In the Residential aged care facility setting, the SUNBEAM trial is evidenced to reduce falls prevalence in participating residents. This pilot aimed to discover if exercise prescription modeled on the SUNBEAM trial could be delivered in a remote format to in-home clients and result in improvement in strength, mobility and balance scores associated with a reduced risk of falling.

METHOD
The pilot commenced in April 2023 and was delivered by an Accredited Exercise Physiologist for a period of 14 weeks, offering a total of 28 hours of exercise to 6 participants with a history of falls. Participants were provided with a home exercise kit for use and all sessions were conducted as individual appointments, using videoconferencing via the telehealth platform, Coviu. A series of strength and balance related outcome measures and assessments were collected using modified methodology for telehealth.

RESULTS
The individual results of the program demonstrated gains in strength and balance, directly linked to reducing falls risk. Participants reported meaningful impacts on sense of self from the program.

CONCLUSION
The pilot was successful in proving the concept of a remotely delivered falls prevention exercise-based program can work for the in-home aged care setting. This warrants future efforts to expand on findings to benefit the wider aged care population residing in their own homes.
FATIGUE SCIENCE INFORMING LONG COVID RECOVERY: A CASE STUDY
Authors: Giles Mrs Adriana , Phillips Dr Vicky , Sinclair Mr Chris 
Published: May 2024

CASE SETTING
42-year-old female client referred for unmanaged long covid symptoms, six months following severe acute COVID-19 infection. Referred by an occupational therapist under Life Insurance to restore health and function for return to work (RTW). Experiencing cognitive and physical fatigue, muscular aches, breathlessness, post-exertional malaise, reduced cognitive capacity and exacerbated asthma symptoms at referral. Reduced functional capacity to perform activities of daily living and usual work duties and hours.

TREATMENT/REHABILITATION PROVIDED
14 hours of exercise physiology was delivered by telehealth over nine months, during fortnightly or monthly consultations. Additional multidisciplinary collaboration occurred with occupational therapist, return to work co-ordinator, and general practitioner. The intervention consisted of educational coaching sessions on the physiology of fatigue, pacing strategies, individualised wellness strategies (sleep, mindfulness/relaxation, exercise, diet), relapse planning, and RTW planning. A commercially available wearable device obtained 24/7 biometric data, which tracked resting heart rate variability (rHRV), resting heart rate, respiratory rate, and sleep performance. rHRV objectively measured fatigue. Wellness strategies were coached from analysing the impact of client behaviours on rHRV trends. Two functional goals of housework and socialising were established.

RESULTS
Validated inventories measured self-reported improvements in; fatigue symptoms: 12-item SPHERE-12, range: 0-68 points [42 baseline; 4 final]; function: two 11-item patient-specific functional scale [housework, socialising], range: 0-20 points [5 baseline; 19 final]; and quality of life: 16-item quality of life scale, range: 0-112 [54 baseline; 79 final]. rHRV improved [10ms baseline, 56ms final]. RTW improved from four days/week to five days/week in her pre-disability role as a client manager.

REFLECTIONS/LEARNINGS
rHRV provided an objective marker of fatigue. The subject responded positively to rHRV monitoring. Real time biometric data enables individualised fatigue coaching including behaviour change, wellness and planning/pacing strategies. This approach improved fatigue and restored function to perform daily activities and RTW.
THE EFFECT OF INTRA-INFUSION EXERCISE ON CHEMOTHERAPY SIDE EFFECTS; AN INTERIM ANALYSIS
Authors: Seet-Lee Catherine , Yee Jasmine , Marvin Sarah , Mizrahi Dr David , Mahon Kate , Lacey A/Prof Judith , Edwards Dr Kate 
Published: May 2024

INTRODUCTION
Chemotherapy treatment results in side effects that impact quality of life and physical activity behaviours. Aerobic exercise in parallel with chemotherapy reduces side effects particularly fatigue and improves quality of life. Our recent clinical pilot work has shown that an acute bout of aerobic exercise increases blood flow to tumours. Therefore, if exercise is performed during chemotherapy (intra-infusion exercise), the result may be increased drug delivery and treatment efficacy. Intra-infusion exercise also provides a supervised opportunity to overcome patient-reported barriers to exercise during a period where a patient would be otherwise sedentary. AIM: The aim of this ongoing randomised controlled trial is to determine the effects of aerobic intra-infusion exercise on chemotherapy side effects and physical activity behaviours.

METHODS
Adults under 75 years receiving chemotherapy with stage I-III breast, colorectal or ovarian cancer, and ECOG 0-2 were eligible. Four chemotherapy sessions were included, cycle 1 (C1) a baseline and cycles 2-4 (C2-4) included exercise intervention or usual care. The exercise task was 20-minutes of moderate intensity cycling (40-50% heart rate reserve) during infusion. All participants received exercise education. A 7-day symptom diary (including Brief Fatigue Inventory (BFI) and Edmonton Symptom Assessment System (ESAS)) was completed following C1-C4 and an activity monitor worn.

RESULTS
Nineteen participants have completed the trial (79% female), with no adverse events reported in either group. Physical symptoms increased across cycles in both groups (p=0.003). 1-week mean ESAS physical symptoms total in the exercise group (C1 16±9.8, C4 23±13.7) and control group (C1 18±7.1, C4 23±12.7) were similar. No significant effects were seen for fatigue or step count.

CONCLUSION
Intra-infusion exercise is safe and does not increase side effects in patients receiving chemotherapy. Expected increases in physical symptoms were observed without difference between usual care and exercise. Further analysis with ongoing recruitment will continue to examine any differences between groups.
DOES EXERCISE CHANGE BLOOD FLOW TO TUMOURS? ACUTE AEROBIC EXERCISE EFFECTS ON LIVER METASTASES BLOOD FLOW: A CASE SERIES
Authors: Seet-Lee Catherine , Yee Jasmine , Clarke Jillian , Edwards Dr Kate 
Published: May 2024

AIM
Effective cancer treatment relies on intravenous chemotherapy penetrating the entire tumour in sufficient concentrations, which is largely reliant on effective blood supply into and within the tumour. However, tumours contain abnormal vasculature with inefficient blood perfusion leading to the inability for chemotherapy to reach the target tumour. Pre-clinical evidence suggests acute exercise may increase blood flow by 200%. However, most pre-clinical studies investigate the effects of light-to-moderate intensity exercise and subsequently there is little evidence regarding the most effective exercise intensity for improved tumour vasculature. Therefore, the aim of this ongoing case series is to determine whether exercise changes tumour blood flow in a clinical model using non-invasive techniques, and how exercise intensity effects degree of change in blood flow to tumours in patients with liver metastases.

METHODS
Participants were eligible if they were aged over 18 years, had stage IV cancer with liver metastasis and ECOG 0-2. The study visit consisted of an aerobic fitness test (YMCA) to determine cardiorespiratory fitness and three 5-minute bouts of exercise at low, moderate and high intensities. After each exercise bout, Doppler ultrasound was used to measure a liver tumour vessel and the hepatic artery (as a control) to determine blood flow parameters.

RESULTS
Exercise increased peak systolic velocities (PSV) to liver tumours at all intensities compared to rest. Moderate and high exercise intensities showed a marked increase in PSV within the first 2 minutes after exercise. The hepatic artery showed less variability in PSV with time compared to the liver tumour. Cardiorespiratory fitness did not affect tumour PSV.

CONCLUSION
The results of this case series thus far suggest that exercise increases tumour blood flow at all exercise intensities with particular emphasis on moderate and high intensities. This supports the potential for using exercise as an adjunct to standard treatment to improve chemotherapy efficacy.
