Study type
Interventional
Description of intervention(s) / exposure
The intervention group will attend the health clinic 3 times per week and undertake the ACTIVE-TBI protocol with the direct guidance of an accredited exercise physiologist. Pre and post measures of cognitive performance and DTI neuroimaging will be taken for all eligible participants.

Prescribed exercise commences as soon as feasible after study entry. The delivery of the intervention is closely supervised by an experienced, Exercise and Sports Science Australia (ESSA) AEP.

The Intervention Protocol incorporates: a) strictly defined warm-up and cool down-periods; b) a work phase (a circuit program that ensures sequenced exercises for antagonistic muscle groups); and c) cessation rules (the American College of Sports Medicine (ACSM) Guidelines).

The work phase involves individually-prescribed, supervised, and graded circuit resistance training. The requirements are individually determined using 1-Repetition Maximum (1-RM) strength testing for leg press, chest press and back pull exercises. The same person assesses the 1-RM attempts for all participants. The work phase dose for each participant is set at 50% of 1-RM, which is classified by ACSM as light intensity.

The clinic is equipped with pneumatic resistance training machines, specially designed for clinical populations (Ab HUR Oy, Finland). These machines enable precise quantification of resistance, and automated load control, which aids accuracy, safety, and usability (users do not require prior experience with exercise machines). This equipment electronically records all individual work phase data (intensity, volume).

The work phase comprises 13 light-resistance machine-based exercises in each aerobic circuit (chest press, leg press, shoulder press, lat pulldown, lat row, abdominals, back extension, tricep push down (cable), seated bicep curl (cable) and leg extension, leg curl, leg abduction and adduction). Participants will exercise for a 30-second period that includes 20 repetitions at the prescribed load, followed by a 30-second rest. All intervals are timed by the supervisor. The training is graduated by: a) increasing session duration e.g., from week, 1 circuit (12 mins) and up to week 8, 4 circuits (48 min), and; b) two repeat 1-RM tests (Weeks 3, 5) for revised load prescription, if required.

There are 8 weeks with 3 training sessions per week (24 sessions, total). The session duration varies as noted above. There is one session per day, with a minimum of 48 hours rest in between sessions. The pre and post assessments occur in the week immediately pre and post the intervention, respectively.

Participants in the ACTIVE-TBI group will be eligible to discontinue the exercise program if they meet any of the following criteria:

The participant is no longer at risk of persistent symptoms (measured using the RPQ-3)
Have been medically cleared to return to contact sport by their doctor.

Key exclusion criteria

Statistical methods / analysis
Group comparisons will be made using GEE or GLMM to control for baseline. Pre-to-post comparisons will be via One-Way ANOVA using an intention-to-treat analysis. Correlations will be used to capture the expected decrease in participants meeting criteria for postconcussion syndrome pre to post intervention. Descriptive data will be used to capture symptom reduction will be associated with improvements in secondary outcomes. Symptom differences between the treatment as usual and ACTIVE-TBI participants are tested with ANOVA at program end.

Summary
Brief summary
This project establishes a proof of concept for an intervention that uses prescribed physical activity intervention, ACTIVE-TBI, to stop the progression of postconcussion symptoms. In patients slow-to-recover from mTBI, persistent postconcussion symptoms adversely impact on patients’ productivity, relationships, and quality of life. We predict a reduction in postconcussion symptoms after the physical activity intervention, ACTIVE-TBI. Other expected outcomes include: decrease of return-to-work or study times; decreased health service utilisation, and improved recovery outlook.
