Kuormitus on elimist\u00f6\u00f6n kohdistuva stressitekij\u00e4, joka saa aikaan muutoksia sen toiminnassa. Kuormitus voidaan jakaa teoreettisesti ulkoiseen ja sis\u00e4iseen kuormitukseen.

Training load is a stressor that causes changes in the body\u2019s homeostasis. Training load can be theoretically divided into external and internal load. External training load means externally visible things, i.e. work and power in dynamic motion. Internal training load refers to the body\u2019s response to the external training load, which is always training load specific as well as individual. Internal load in particular is a complex issue and measuring it is challenging in some cases. The purpose of this study was to find out the connections between internal and external training load and to study the methods of measuring them in ice-hockey games.\n\nMethods. External training load was measured using local positioning system. The variables of the external load were the total distance, the distance in different speeds, and the number of accelerations and decelerations with different intensities. All external training load variables were also analysed in relation to playing time. Internal subjective training load was measured using sRPE and sRPE-TL. Internal objective training load was analysed with different heart rate variables, such as TRIMP. One team from the Finnish ice hockey main series, the League, participated in the study. There were a total of 25 subjects. The study was carried out by measuring internal and external training load for one season, i.e. total of 59 games.\n\nResults. The external training load of this study corresponded to the external training load of previous international and NHL games. Session-RPE and heart rate based measurements were moderately correlated and weaker than in the previous studies (sRPE vs. TRIMP: r = 0.44; p < 0.001; sRPE-TL vs. TRIMP: r = 0.60; p < 0.001). Session-RPE correlated more consistently and more strongly with different external training load variables (sRPE-TL vs. total distance: r = 0.86; p < 0.001; TRIMP vs. total distance: r = 0.45; p < 0.001). The variables associated with the high intensity external training load correlated most strongly with sRPE and sRPE-TL (sRPE vs. high-intensity distance: r = 0.52; p < 0.01; TRIMP/min vs. high-intensity distance: r = 0.34; p < 0.01. Heart rate variables correlated mainly to variables associated with the low intensity of external training load.\n\nDiscussion and conclusion. The external training load and the nature of ice hockey is very high intensity and intermittent. The high intensity bursts are also usually very short compared to other team sports. Maybe because of these reasons, heart rate derived variables did not appear to be as good measures of internal training load as has been observed in previous studies and in other team sports. Subjective measures of internal training load seem to be suitable methods for measuring the total internal training load in ice hockey games.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-06-30T10:20:23Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-30T10:20:23Z (GMT).
