- Description: Cancer is a prevalent disease with significant morbidity and mortality rates. Exercise interventions implemented before, during, or after cancer-based surgeries have shown promising benefits in improving fitness, postoperative complications, and quality of life. This thesis comprises three original research chapters aimed at investigating the effect of perioperative and preoperative 'prehabilitation' exercise in breast, colorectal, and prostate cancer patients. The first study focused on exploring exercise therapy interventions and their impact on cardio-respiratory fitness and 30-day postoperative outcomes in colorectal cancer patients. The systematic review and meta-analysis (N= 411 intervention and N= 368 control) revealed a small but significant improvement in cardio-respiratory fitness (SMD = 0.18; 95% CI = 0.03, 0.32; p < 0.05) with exercise interventions, although no significant impact on 30-day postoperative outcomes was observed. In the second study, various exercise types, including aerobic, resistance, flexibility, and mind-body exercises (alone or in combination), were compared in terms of their effect on cardio-respiratory fitness and 30-day postoperative outcomes in colorectal cancer patients (N= 411 intervention and N= 368 control). The network meta-analysis findings indicated that engaging in aerobic exercise alone (SMD = 0.30) or a combination of aerobic, resistance, and flexibility exercises (SMD = 0.57) yielded the most significant improvements in cardio-respiratory fitness. The final study examined the efficacy of pre-surgical aerobic exercise (prehabilitation) therapy in relation to post-operative cardio-respiratory fitness, quality of life, and 30-day postoperative outcomes in the Grampians Region of Victoria. The prehabilitation (PREHAB) group included a supervised aerobic based program which would see patients exercise every two/three days for a minimum of 2 weeks. A total of 11 PREHAB and 9 usual care (UCARE) patients were enrolled and analysed. The study showed that a prehabilitation exercise program resulted in small clinical improvements in some markers of cardio-respiratory fitness (+1.5% and +1.2% for absolute and relative V̇O2peak, respectively) and is safe and feasible. However, no significant improvements were observed in quality of life and 30-day postoperative outcomes. While the overall findings demonstrate some positive effects of perioperative and specifically prehabilitation exercise, it is important to consider the magnitude of these effects and any specific factors contributing to their success, if applicable. Further research is needed to fully understand the potential benefits and limitations of exercise before, during and after surgery in this patient population.

- Description: Background: Exercise has been identified as an allied health strategy that can support the management of depression in older adults, yet the relative effectiveness for different exercise modalities is unknown. To meet this gap in knowledge, we present a systematic review and network meta-analysis of randomised controlled trials (RCTs) to examine the head-to-head effectiveness of aerobic, resistance, and mind-body exercise to mitigate depressive symptoms in adults aged ≥ 65 years. Methods: A PRISMA-NMA compliant review was undertaken on RCTs from inception to September 12 th, 2019. PubMed, Web of Science, CINAHL, Health Source: Nursing/Academic Edition, PsycARTICLES, PsycINFO, and SPORTDiscus were systematically searched for eligible RCTs enrolling adults with a mean age ≥ 65 years, comparing one or more exercise intervention arms, and which used valid measures of depressive symptomology. Comparative effectiveness was evaluated using network meta-analysis to combine direct and indirect evidence, controlling for inherent variation in trial control groups. Results: The systematic review included 81 RCTs, with 69 meeting eligibility for the network meta-analysis ( n = 5,379 participants). Pooled analysis found each exercise type to be effective compared with controls (Hedges' g = -0.27 to -0.51). Relative head-to-head comparisons were statistically comparable between exercise types: resistance versus aerobic (Hedges' g = -0.06, PrI = -0.91, 0.79), mind-body versus aerobic (Hedges' g = -0.12, PrI = -0.95, 0.72), mind-body versus resistance (Hedges' g = -0.06, PrI = -0.90, 0.79). High levels of compliance were demonstrated for each exercise treatment. Conclusions: Aerobic, resistance, and mind-body exercise demonstrate equivalence to mitigate symptoms of depression in older adults aged ≥ 65 years, with comparably encouraging levels of compliance to exercise treatment. These findings coalesce with previous findings in clinically depressed older adults to encourage personal preference when prescribing exercise for depressive symptoms in older adults, irrespective of severity.

- Description: Background: Few studies have directly compared the effects of different exercise therapies on clinical depression in older adults. Thus, we conducted a systematic review and network meta-analysis of current evidence from randomised controlled trials (RCTs) to compare the effectiveness of three major exercise types (aerobic, resistance, and mind-body exercise) in clinically depressed older adults. Methods: We followed PRISMA-NMA guidelines and searched databases for eligible RCTs (inception – September 12th, 2019). RCTs were eligible if they included clinically depressed adults aged >65 years, implemented one or more exercise therapy arms using aerobic, resistance, or mind-body exercise, and assessed depressive symptoms at baseline and follow-up using a validated clinical questionnaire. Results: A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = −0.87 to −1.38), followed by aerobic exercise (g = −0.51 to −1.02), and resistance exercise (g = −0.41 to −0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = −0.10, PrI = −2.23, 2.03), mind-body versus aerobic (g = −0.36, PrI = −2.69, 1.97), or mind-body versus resistance (g = −0.46, PrI = −2.75, 1.83). Conclusions: These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression. © 2019

- Description: Objective: The primary objective of this systematic review and meta-analysis was to compare the effects of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) and usual care (UC) on cardiorespiratory fitness (peak V̇O2) in cancer patients and survivors. Secondary objectives were to compare the effects of HIIT versus MICT and UC on other cardiopulmonary exercise testing (CPET) indices. Safety and adherence to HIIT were also evaluated. Methods: A systematic review and meta-analysis of controlled trials were undertaken using eligible studies from electronic database searching (inception—December 2019). Mean differences (MD) with 95% confidence intervals (CI) were compared and heterogeneity assessed using Cochran's Q and I2 statistic. Results: Twelve eligible studies included 516 participants with post-intervention CPET data. No serious adverse events occurred. Adherence to HIIT ranged between 71.2% and 95.6%. HIIT had significantly higher peak V̇O2 compared with UC (MD = 2.11 ml kg−1 min−1, 95% CI 0.75–3.47, p =.002). No significant difference was found between HIIT and MICT (MD = 2.03 ml kg−1 min−1, 95%CI −0.75–4.83, p =.15). HIIT was more effective than UC to improve peak oxygen pulse (MD = 1.59 ml/beat, 95%CI 0.06–3.12, p =.04). Conclusions: Quantitative assessment of HIIT studies indicates good compliance, with a significant effect on peak V̇O2 and peak oxygen pulse compared with UC in cancer patients and survivors. HIIT demonstrates a comparable effect with MICT to improve peak V̇O2. © 2020 John Wiley & Sons Ltd
