Description of intervention(s) / exposure
The objective of the study is to verify if Slackline training sessions could be helpful in improving balance in healthy young people. The project will allow to check the impact of Slackline training on changes in the balance in students practicing moderate-intensity physical activity.


The research will be led by two university research student who will work under the substantive support of a university researcher. Training will be conducted in the park at the university

For the study will be recruited 28 students of the Opole University of Technology declaring that they are healthy and do not play any sport professionally. Each subject will undergo initial and final examinations. Test will be carried out using two selected protocols available on the Balance Master® platform.
- Tandem Walk Test- Specifies the gait characteristics of the patient crossing the measurement platform using tandem walk
- Modified Clinical Test of the Sensory Interaction on Balance- Specifies the postural swing speed in 4 different conditions:
1) patient is standing on a stable ground with open eyes
2) patient is standing on a stable ground with closed eyes
3) patient is standing on an unstable ground with open eyes
4) patient is standing on an unstable ground with closed eyes
The subjects will be randomly assigned to 2 groups.

First group will participate in 5 days intervention. Trainings will be held 5 times a week (from Monday to Friday) and each session will last 15 minutes. The task will be to maintain balance crossing a 5 cm wide and 9m length nylon tape stretched at a height of 50cm. Gibbon CLASSIC LINE 15M will be used for slackline training. The most versatile tape offered by Gibbon Slacklines. The subjects' task will be to maintain balance as long as possible and cover the longest possible distance. Each fall will result in a return to the beginning of the tape. Throughout the training, heart rate will be monitored by the Polar OH1optical heart rate sensor. Polar OH1 is a monitor armband that combines versatility, comfort and simplicity.
Second group is the control group that will only undergo initial and final tests.

Balance performance assessed using Tandem Walk Test and Modified Clinical Test of the Sensory Interaction on Balance test
Timepoint [1] 321949 0
1. baseline - Initial assessment of the participants
2. Final assessment of participants after 5 days of Slackline training
Secondary outcome [1] 376773 0
Physical activity level assessed using SenseWear Armband. The devices allow to evaluate energy expenditure expressed in MET and kilocalories, additionally monitor such parameters as: total number of steps, level and duration of physical activity, duration of sleep, rest period. All component results allow to determine one composite outcome.

Efficacy
Statistical methods / analysis
The statistical analysis will be carried out using STATISTICA 13 software. It is planned to determine the distribution of variables. In the absence of Fundamentals reject the hypothesis of a normal distribution is performed ANOVA with Tukey's test reproducible measurements do post-hoc, and with the rejection of the hypothesis of a normal distribution will be done Friedman ANOVA. The statistical significance level was accepted at p<0.05 for all tests.

Summary
Brief summary
The intervention will consist of five 15-minute training sessions.

The aim of the research is to evaluate the effects of slackline training.
We are going to:
1) Monitor physical activity in healthy people during training by evaluating energy expenditure, number of steps, change in heart rate.
2. evaluate the effects of training by analyzing the mechanisms of postural control using stabilometric platforms.

We assume that as a result of the intervention, posture control mechanisms will improve.
