Methods: The experiment involved 60 male rats from the Wistar strain, aged 8 weeks and 36 weeks. The animals were separated into 6 groups: 3 groups (I, II, III) of 8-week old animals, and 3 groups (IV, V, VI) of 36-week old animals. The rats in the study groups i.e. II, III, V, and VI were made to swim till exhaustion in water at 4oC and at 25°C. After the experiment blood samples were collected from each rat and hematological and cytological determinations were completed for each sample. Results: Compared with the control group, in the rats from group II (8-week old, swimming in water at 4oC) a significant increase was noted in the RBC count, Hb, Ht, and MCHC, and MCH indices, whereas in the rats from group V (36-week old, swimming in water at 4oC) increases were noted in the MCHC and MCH indices (again when compared with the control group). In the rats from group III (8-week old, swimming in water at 25oC), compared with the control group, significant increases were noted in the Hb and Ht parameters, as well as in the MCHC, and MCH indices, whereas in the group VI rats (36-week old swimming at 25oC) – the increase was noted in the MCHC index. No alterations were found in the reticulocyte count, and in poikilocytes during exercise in water at low temperatures in either the 8-week or 36-week old rats. Conclusions: The increases in the majority of blood parameters, testifies to the dehydration of the body during physical exercise which in turn affects the microcirculation function. The lack of alterations in the reticulocyte count in the peripheral blood may, in turn, testify to the ineffectiveness of low temperature during exercise upon the function of the bone marrow.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"10 1","pages":"201-208"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81535330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: The purpose of this study was to compare the potentiating effects of a depth jump vs. a box jump warm-up on vertical jump performance. Methods: Eight collegiate and nine club female volleyball players participated on three testing days separated by 48 hours. Participants performed three pre-test countermovement vertical jumps with arm-swing then completed three experimental conditions in random order: control (no intervention), box jump (onto a box), and depth jump (stepping off a box with immediate maximal rebound). They then performed three post-test jumps. Results: Analysis revealed no significant (P < 0.05) interactions, but there was a main effect for time with all scores decreasing: vertical jump height (pre-34.31 ± 5.89cm; post-33.17 ± 5.86cm), relative ground reaction force (pre-24.18 ± 3.66N/kg; post-23.53 ± 3.66N/kg), and take-off velocity (pre-2.53 ± 0.29m/s; post-2.49 ± 0.30 m/s). Conclusions: It was concluded that using 10 depth or box jump warm-ups at the box height used in this study, with 10 minutes rest is not recommended to increase subsequent vertical jump performance in female collegiate volleyball players.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"95 1","pages":"103-106"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86799830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Autonomic contribution to cardio-deceleration following exercise has been studied in adults; however, no data are available for endurance trained juvenile athletes. Aim: The aim of this study was to evaluate the association between the increase in heart rate following exercise and any change in HRV frequency components in trained juveniles. Methods: A 6 min resting ECG (lead 2) was recorded from trained juvenile cyclists (23 male, 7 female, mean age 14.7 years), before (Pre) and after (Post) incremental exercise to volitional exhaustion on a stationary cycle ergometer. Each subject performed a progressive ramp protocol where power increased by 20W min -1 , with initial power set at 60 W for females and 100 W for males. Oxygen uptake ( ¦O 2 ) was measured using breath-by-breath techniques. ECG was analysed in both time and frequency domains using commercially available software. Results: Mean ¦O 2 max was 75.5 ml Kg -1 min -1 , and mean power at ¦O 2 max was 440 W. The R-R interval SD was lower following exercise (Pre: 86ms vs. Post: 36ms, P <0.01). Normalised high frequency HRV was lower (Pre: 36.5 vs. Post: 18.7, P <0.01) and normalised low frequency HRV was higher (Pre: 58.5 vs. Post: 75.0, P <0.01) following exercise. Conclusions: In elite juvenile athletes there were no associations between exercise-induced changes in high frequency variability and heart rate ( R 2 =0.073). This suggests that in elite juveniles, the heart may be less sensitive to vagal influences - a suggestion further supported by the relatively high pre-exercise resting heart rates with normal high frequency variability.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"400 1","pages":"107-113"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74933922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The research material was a group of 100 people (86 men and 14 women) aged 16 to 39. All those persons practiced selected sport disciplines professionally or semi-professionally. From the original group of 100 persons, 76 persons who have previously suffered knee injury while practicing sport were selected for the purpose of final analysis. A question- naire was constructed for the purposes of the research in order to assess the frequency of knee joint injuries in winter sport disciplines and for the purpose of assessment of the post-injury treatment. The questionnaire included closed questions and TSK scales (Tampa Scale of Kinesiophobia). Results: Following the analysis of the research carried out among sportsmen practicing winter sports one may conclude that downhill skiing and ice hockey were characterized by the highest rate of knee injuries (skiers - 75% of the respondents, hockey players - 82%). In the case of ski jumping, the rate of injuries was slightly lower (53% of respondents). The research results show that in most cases the sportsmen suffered a knee joint injury during competitions but also show that the most frequent cause of injury in all of the discussed disciplines is the lack of warm-up or inappropriate warm-up. Conclusions: The knee joint injury results in damage of anatomic structures of the joint. The main type of knee injury suffered by the sportsmen representing all three sport disciplines was the joint sprain.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"9 12","pages":"132-139"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72536118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
