Slopestyle snowboarding is an injury-prone technical sport, and little research has been done on the training load. This Master's thesis examines the training load of competitive snowboarders during a six-day training camp. The purpose of the work is to measure does snowboarding training cause training response and what are the suitable methods for monitoring the training load.\nEight young subjects aged 17\u201319 took part in measurements during the training camp, where the state of the autonomic nervous system was monitored throughout the camp with an orthostatic heart rate test, as well as nighttime heart rate monitoring for resting heart rate and heart rate variability. The performance variables maximal isometric leg press (MVC) and Counter Movement Jump (CMJ) were measured before the start of training and after the end of the camp, as well as during two follow-up days. In addition, during the camp and the follow-up period, the subjects' RPE, which evaluates the perceived load, was asked.\nIn the MVC and CMJ tests, which measure performance, no significant changes were observed in any of the measurement points. In orthostatic heart rate measurements, significant changes were observed between the Pre \u2013 Mid measurement points regarding resting heart rate and heart rate variability (p<0.05). HRV decreased by 24 % and resting heart rate increased by 16,5 %. In addition, a significant change in RPE was observed between Pre \u2013 Mid measurement points as it increased by36 % (p<0.05). No statistically significant correlations were observed between heart rate variables and RPE.\nThe training response caused by freestyle snowboarding training could be detected by monitoring the state of the autonomic nervous system, as well as by surveying RPE. Training did not cause a significant change in the performance variables. The RPE survey and the monitoring of heart rate variables could be used to monitor the load. It is important to consider the training load to minimize the risk of injury especially when practicing new tricks.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-03-29T08:35:57Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-03-29T08:35:57Z (GMT).
