Presently the training method is also commonly used by recreational athletes, as HIT exercises are efficient and quick to implement. In recent years HIT has also been used in strength training, by utilizing body weight as well as employing various modes of resistance training equipment.\r\nThe aim of this study was to examine the effects of two different HIT exercise models (HIT 1: 4*4 min 85%/2 min and HIT 2: 10*1 min 95%/1\u00bdmin) on aerobic performance (VO2peak), strength and body composition by means of two study groups and a third control group. Both main groups also performed two separate HIT circuit training programs utilizing their own body weight. The participants were 33 (average age 47.6 \u00b1 5.4 years) normally employed persons, and the training cycle was six weeks. In the beginning and after six week training body composition was measured by bioelectrical impedance analysis, waist circumference was measured and (VO2peak) was estimated by submaximal bicycle ergometer test. In addition, jump height and muscle fitness tests (sit-ups, squats and pull-ups) were performed. Venous blood samples were collected after overnight fast for cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides. In terms of body composition only the HIT 2 (short interval) \u2013group experienced a significant weight loss of 0.9(\u00b11.1) (p<0.05). Otherwise there were no significant changes in either group. There were no significant changes in cholesterol, LDL-cholesterol and triglycerides However, against all expectations, \u201cgood\u201d HDL - cholesterol increased in the control group by significantly, 6.4(\u00b17.4)% (p<0.05). Only HIT 2 -group had also a significant improvement in VO2max 6.9(\u00b18.8) (p<0.05).\r\nHIT 2 - group showed 1 % increase in jump height. When comparing the HIT 1 and HIT 2 -groups the study showed a statistically significant difference (0.048) between the groups in average improvement. Muscle fitness improved with statistical significance for both HIT 1 and HIT 2 \u2013groups. In the HIT 1 \u2013group the average increase was 20.2%-38.1%, whereas in the HIT 2 \u2013group the average improvement in various muscular endurance movements was 10.8%-12.9%. The greater improvement of HIT 1 \u2013group is likely the result of the group\u2019s individuals having a lower starting level. In conclusion it can be stated that it is clear that HIT training is effective for improving both oxygen uptake and muscle fitness while having small effects on body composition. The training cycle of six weeks was too short to have an impact on blood lipids levels.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Heikki V\u00e4nsk\u00e4 (hejuvans) on 2017-08-25 13:47:59.293371.
