Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Students attending Launceston Church Grammar School (LCGS) who play Australian Rules Football (ARF) or Soccer will be recruited to participate in an intervention study over a 10-week period that is proposed to occur as soon as Ethics Approval has been granted. Participants will be between 14 and 18 years of age (Grade 9 to 12) as that is the range of participants playing in the ARF or Soccer first teams at Launceston Grammar. It is expected that some participants will play at the school level only, some will play at the school and club level, and some participants will be state representatives for their specific age group. All participants will be part of the school's ARF or Soccer first team though. At the start of the 10-week data collection period, participants’ anthropometric measures will be taken, and six physical tests completed to determine baseline fitness and neuromuscular function levels. Participants will report their level of sports participation by completing a 2-question survey on the Teambuildr Strength and Conditioning Software (TeamBuildr, LLC). The questions will include:
1) How long have you been participating/training in ARF or Soccer?
2) At which level do you compete in ARF or Soccer? – with options including:
i) Socially only at school
ii) Competitively at school and club
iii) Development/State Representative
The participants will be randomly grouped into control and intervention groups, matched for age, physical characteristics, physical testing results, and the highest level they currently compete at in ARF or Soccer. The control group will complete their usual training program, led by LCGS coaches and Sports staff, while the intervention group will be provided with a 10-week periodised strength and conditioning training program with set weekly total distance and weekly high-speed running distance targets. The achievement of these targets will be monitored by collecting internal and external load data, with modifications made to the weekly training sessions to ensure individuals meet the required targets.

Participants will be provided with specific football or soccer activities and conditioning drills to complete during school football training sessions. This might include kick-passing drills where participants are required to kick the ball to a teammate and then run 50 meters to get to the next kicking position. Running/conditioning drills might include repeated sprint efforts where participants will complete sets of four to six repeated 50 to 60-meter sprint efforts, or longer but slower running efforts such as six by 200-meter running efforts.

Participants in the intervention group will be addressed both one-on-one and as a group during their scheduled school-based football or soccer training. Participants that need to perform additional training to meet their weekly training targets will be informed individually before the start of training and then addressed as a group during training.

The intensity of the exercises will depend on what the participants have completed in training during the week. For example, if participants have reached their high-intensity running distance targets for the week but still need to reach their total running distance target, then lower intensity exercises will be completed.

Participants will complete these extra sessions once a week during the Wednesday school football or soccer training sessions. The duration of these activities/sessions will vary depending on the distance required to be completed to reach the weekly targets, however, it is expected that these sessions will last between 10 to 20 minutes.

Both groups will provide internal workloads through reporting session-RPE (Rate of Perceived Exertion) load, while external workloads of all on-field training sessions and games will be measured using GPS tracking devices. Subjective wellbeing and academic stress, along with injury reporting will be monitored through the completion of a daily questionnaire developed elsewhere (McLean, Coutts, Kelly, McGuigan, & Cormack, 2010; Williams, Pendlebury, Thomas, & Smith, 2017). The participants will perform weekly neuromuscular function testing through the completion of a countermovement jump (CMJ) test. Participants will also complete the Behavioural Regulation of Sport Questionnaire (Clancy, Herring, & Campbell, 2017; Viladrich et al., 2013) pre-, during-, and post-intervention to determine any changes in motivation levels to participate in sports throughout the study. The six physical tests and anthropometric measures will be repeated after the 10-week intervention period to measure any changes in fitness levels, neuromuscular function, and body composition.

Comparator / control treatment
The control treatment involves not providing any program modification to the control group. That means the control group receives no treatment and will continue to perform or participate in their regular training routines.

Outcomes
Primary outcome [1] 331065 0
Change in physical fitness characteristics as assessed by the six physical tests, which will include the sprint test, the 505 change of direction test, the countermovement jump test, the 1-minute push-up test, the 1-minute sit-up test, and the YoYo IR1 test.
Timepoint [1] 331065 0
10-weeks post the baseline fitness testing

Change in neuromuscular function as assessed by countermovement jump test
Timepoint [2] 331066 0
Weekly countermovement jump test and after the 10-week intervention
Primary outcome [3] 331067 0
Changes in anthropometric characteristics will be assessed by measuring the changes in body mass index (BMI) which will be calculated by measuring the changes in body mass with digital scales and standing height with a portable stadiometer, changes in hip and waist circumferences measured with a measuring tape, and changes body fat percentage as estimated by measuring the sum of four skinfolds with a Harpenden calliper.

10-weeks post the baseline fitness testing
Secondary outcome [1] 408617 0
Primary outcome [4]: Change in wellbeing and academic stress which is a composite outcome. This is subjectively assessed through weekly completion of the subjective feeling of fatigue questionnaire developed by McLean et al. (2010) and adapted for this study, which assesses aspects of sleep quality, mood, stress, energy, muscle soreness, and academic stress on a 5-point Likert scale.
