Brief summary
Almost half of Australians will have a mental health condition in their lifetime, with 3 million adults having anxiety and/or depression in any year. Exercise has recently received a lot of attention for its ability to help prevent and manage symptoms of depression, as well as improving physical health. Mindfulness, which is attention to the present moment, also demonstrates positive effects on mood and mental health, however, not much is known about the effects of combining the two activities on mood in people with depression/anxiety. Yoga is an increasingly popular activity in Australia, and essentially combines exercise and mindfulness together in varying combinations, depending on the type of yoga practiced. We are interested in the effect of different combinations of exercise and mindfulness, such as exercise without mindfulness (cycling), mindfulness without exercise (yin yoga) and exercise and mindfulness combined (vinyasa yoga), has on mood state in people with depression and/or anxiety. This study involves doing a 30-minute bout of different combinations of yoga, exercise and mindfulness each week, and goes for 6 weeks in total. We are interested in measuring mood state, depression, anxiety & stress scores, sleep quality, expectation of the condition’s effectiveness, as well as some basic physical health measures such as blood pressure and blood glucose levels, before and after each session. The primary aim of this study is to investigate and compare changes in mood in people with diagnosed depression/anxiety after engaging in 30 minutes of physically active yoga (vinyasa) or non-physically active yoga (yin). The hypotheses for the study are: 1. Physically active yoga (vinyasa) will have a greater effect on improving mood in people with depression/anxiety than mindfulness-based yoga (yin). 2. Physically active yoga (vinyasa) will have a greater effect on improving mood in people with depression/anxiety than sham control and attention control. 3. Mindfulness-based yoga (yin) will have a greater effect on improving mood in people with depression/anxiety than sham control and attention control. Secondary questions that we intend to explore are: 1. Are acute changes in mood present 24 hours post yoga? 2. What are the acute effects of vinyasa and yin yoga on cardio-metabolic health measures (central blood pressure, augmentation index, blood glucose levels)? 3. Which condition scored the highest on the credibility expectancy questionnaire?
Interventions
All conditions will be supervised by an Accredited Exercise Physiologist and delivered in a one-on-one format. Due to the cross-over study design, participants will complete 1 x each condition (including both control conditions) exactly 1 week apart. The week in between each condition is the allocated wash-out period. Home adherence is not required for this study.
Mindfulness-based yoga (Yin): a very light, non-active form of yoga that involves long durations (2-4 minutes) in relaxed postures

The week in between each condition is the allocated wash-out period. Home adherence is not required for this study. Mindfulness-based yoga (Yin): a very light, non-active form of yoga that involves long durations (2-4 minutes) in relaxed postures with a focus on mindfulness and awareness to bodily sensations, thoughts, breathing. This will be lead by a video recording for standardisation and will go for 30 minutes. (20-point Borg RPE should be below 8) Exercise & Mindfulness-based yoga (Vinyasa): a moderate-intensity form of yoga that requires attention to breath and bodily movements. A focus on alignment and muscular engagement with some 'flow' sequences (i.e. each breath is synced with one movement). This will be lead by a video recording for standardisation and will go for 30 minutes. (advised Borg RPE = 13) Aerobic exercise: 30 minutes of moderate intensity (self-selected intensity with the instruction of maintaining a Rating of Perceived Exertion: 13) on an exercise bike. Including 5 minutes or warm up at the start and 5 minutes of cool down at the end (30 minutes total). (advised Borg RPE = 13)

Inclusion criteria
Moderate to severe score of depression and/or anxiety as per the Structured Clinical Interview for DSM-5.
Exclusion criteria
If a mental disorder (e.g. psychotic or personality disorders) impairs the participants ability to give informed consent, comprehend reading/writing tasks and/or participate reliably. A physical (e.g., amputation without adequate prosthetic, uncontrolled blood pressure) or cognitive impairment is present that would hinder or restrict any part of the study requirements. Unable to speak, read or write in English. Medication has changed within 4 weeks prior to the intervention. Already undertake a personal yoga or meditation practice (of more than once a week over the last 3 months).
