Impact of weekly Slackline training on human balance.

INTERVENTION: 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 OH1o CONDITION: balance performance; ; balance performance Physical Medicine / Rehabilitation ‐ Other physical medicine / rehabilitation PRIMARY OUTCOME: Balance performance assessed using Tandem Walk Test and Modified Clinical Test of the Sensory Interaction on Balance test[1. baseline ‐ Initial assessment of the participants; 2. Final assessment of participants after 5 days of Slackline training] SECONDARY OUTCOME: Heart rate variability assessed using Polar OH1 optical heart rate sensor. Polar OH1 is a monitor armband that combines versatility, comfort and simplicity[1. baseline ‐ Initial assessment of the participants ; 2. Final assessment of participants after 5 days of Slackline training] 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.[1. baseline ‐ Initial assessment of the participants ; 2. Final assessment of participants after 5 days of Slackline training] INCLUSION CRITERIA: The criteria for inclusion in the study will be: 1. Female and male 2. Aged 19‐26 years, 3. Not practicing regular physical activity and not practicing sports more than 30 minutes per week.
