The purpose of this study was to indicate influence of wearing a warmfresh fabrics diet suit (specially designed cloth) both on body and rectum temperature and further prove the difference the amount of energy conscription. In the study, 16 people (male & female aged 20 to 39) were tested and two different types of suits were used for this test. One is diet suit (suit B) and the other is self-heating suit (suit A) which is made of warmfresh fabrics. The suit A was made of warmfresh 18%, polyurethane 20%, and cotton 62% and the suit B was made of nylon 79.9% and polyurethane 20.1%. While all participants were wearing one suits of two and they were running on the treadmill for 60 minutes with 75% of maximal heart rate. Participants of this test were attached with electrode on forehead, chest, subscapular, arm, thigh, rectal calculating energy consumption of each participant using a gas analyzer. There was no explicit difference between male and female for two suits in case of body temperature. There was significantly higher at post-minutes than at 10 minutes for the temperature of male and female after running on a treadmill. In case of energy consumption, you can check the amount of energy consumption (Male; 10minutes running wearing suit A-12.34±1.22kcal/min, maximum 60 minutes running wearing suit A-13.20±1.23kcal/min, 10minutes running wearing suit B-12.06±1.28kcal/min, maximum 30 minutes running wearing suit B-12.83±1.30kcal/min, Female; 10minutes running wearing suit A-7.02±0.62kcal/min, maximum 60 minutes wearing suit A-7.24±0.79kcal/min, 10 minutes running wearing suit B-7.07±1.12kcal/min, maximum 60 minutes running wearing suit B-7.61±1.13kcal/min.). In conclusion, there was no significant difference for 60 minutes running with VO_2max 60% level, however when participants wore warmfresh fabrics diet suit, the test showed that body temperature of arms, legs went up and this led high energy consumption. In this case, wearing a warmfresh fabrics diet suit could be recommended to increase body temperature.

Effects of 4 weeks living high training low (LHTL) on aerobic exercise capacity, concentration in oxygenated skeletal muscle, cardiac function and time trial in elite middle and long distance runners. Exercise Science. 20(4): 425-440, 2011. Effects of 4 weeks living high training low (LHTL) on aerobic exercise capacity, concentration in oxygenated skeletal muscle, cardiac function and time trial in elite middle and long distance runners. The purpose of this study was examine after 20 athletes of University and high school divided into Living Low Training Low (control) group and Living High Training Low (experimental) group, to effect LHTL that resided 3,000 m normobaric hypoxic chamber more than 16 hours per day, 4 weeks and trained at 700~1,330 m high ground more than 4 hours per day after equipped 3,000m normobaric hypoxic chamber at 1,000 m high ground on aerobic exercise capacity, oxygenated skeletal muscle concentration, cardiac function and performance. The results of this study were as followed: 1) Conditioning variables weren`t different between groups and abnormal results. So, training was desirable. 2) In oxygen transport capacity and blood concentration of Iron (whole body variables), there weren`t difference between groups. 3) In energy expenditure during intensity of LT (16 km/hr) long duration (60 min) treadmill exercise, LHTL group had lower heart rate, oxygen consumption and lactate concentration than LLTL group, so, we verified that LHTL presents effect of running economy. 4) In oxygenated concentration(local variables of vastus lateralis during intensity of LT (130 watt) long duration (30 min) bike exercise, LHTL group had a tendencies of increasing O2Hb and TOI, decreasing HHb than LLTL group, so, raised possibility that LHTL increases oxygen using capacity. 5) Cardiac function (local variables) during intensity of LT (130 watt) long duration (30 min) bike exercise, LHTL group had lower HR and higher SV than LLTL group. so, we verified that LHTL improves oxygen using capacity of cardiac muscle. 6) In performance, all groups had improved 3,000 m and 5,000 m time trial but more improved 3,000 m and 5,000 m time trial in LHTL group. Viewed in these results, we verified possibility of LHTL targeting athletes of University and high school in domestic 700~1,330 m high ground improved performance was caused by improved running economy and cardiac function in whole body and local long duration exercise.

Ham, J. H., Nam, S. S., Park, H. Y., Sunoo, S. Effects of 4 weeks intermittent sprint training on anaerobic energy metabolites and performance in hypobaric hypoxic condition, equivalent to an altitude of 3,000 m. Exercise Science. 20(4): 461-474, 2011. The study was designed to investigate the effects of intermittent sprint training in hypobaric hypoxic condition, equivalent to an altitude of 3,000 m and sea level on anaerobic energy metabolism and performance. Fourteen college male students majoring sports volunteered to participate in this research. Running grade, speed, time, repetition time, and interval between running were 10 percent, 15-17 km/hr, 30 seconds, 10 times, 2 minutes respectively. Training period was 4 weeks. They took 8 weeks rest after first training (4 weeks) in 3,000 m simulated altitude and sea level. Also second training practiced 4 weeks in that order (a cross-over study). The results of this study were as follows. Weight and muscle mass were significantly decreased after 3,000 m simulated altitude training. CPK was not significantly changed after 3,000 m simulated altitude and sea level training. LDH was significantly decreased immediately after exercise and recovery 5 minutes after 3,000 m simulated altitude training. Oxygen transporting capacity of the blood was not significantly changed after 3,000m simulated altitude and sea level training. EPOC was significantly increased after 3,000 m simulated altitude and sea level training. Anaerobic power was significantly increased after 3,000 m simulated altitude training. Leg isokinetic muscular strength was significantly increased after sea level training. But it was significantly decreased after 3,000 m simulated altitude training. 100 m time trial was significantly decreased after 3,000 m simulated altitude training. But 400 m time trial was not significantly changed in two groups. We have demonstrated that weight, muscle mass and 100 m time trial was significantly changed by 4 weeks of intermittent sprint training in hypobaric hypoxic condition, equivalent to an altitude of 3,000 m, whereas the other physiological parameters was not significantly changed in two groups.

선우섭,전정우,김형돈,최영렬 경희대학교 사회체육연구소 1995 體育科學論叢 Vol.- No.8

The purpose of this study was to compare the anthropometric parameters, anaerobic power, isometric peak torque, and isokinetic muscle performance of the college male taekwondo players, female taekwondo players, and female soccer players. Sargent jump was estimated for the anaerobic power. Maximal voluntary force in knee extension was measured before and after a muscle endurance test (MET) by using a Cybex 350 isokinetic dynamometer isometrically at 90˚and con-centrically at the angular velocity of 30˚, 120˚, and 270˚·S-¹, The MET conists of 30 maximal concentric muscle actions at the angular velocity of 270˚·S-¹. The significant group differences were observed in %fat(p<.05) and the male taekwondo players demonstrated the highest mean values. A significant difference (p<.05) was observed in sargent jump between male taekwondo players and female players. The male taekwondo players showed the highest mean value, followed by female soccer and female taekwondo players. In isometric and isokinetic muscular strength test the male taekwondo players showed a significant difference(p<.05) from the female athletes before MET and no differences were found between female taekwondo and soccer players. The similar results in isometric and isokinetic muscular strength were observed after MET except that no significant differences exist between male taekwondo and female soccer players. These results indicates that the correlation exists between sargent jump and knee extension forces. Male taekwondo players showed a significant differences from the female players in total work of MET(p<.01). However, no significant difference were observed between the subjects in knee extension endurance ratio and flexion endurance ratio and recovery ratio. The female taekwondo players showed statistically higher values compared to female soccer and male taekwondo players(p<.05) in recovery ratio of MET. Therefore, it is assumed that there exist gender differences in the muscular endurance, and further research is needed on this issue.
