Methods: Eleven healthy resistance trained men (22.8 ± 3.5) participated into the present study. Maximal isometric strength was determined in the bench press exercise using a load cell. Muscle activation was assessed using surface elec- tromyography (EMG) signals from the muscles pectoralis major, anterior deltoid and posterior deltoid at intensities ranging to 60-90% of maximal voluntary contraction (MVC), in the bench press exercise. This procedure allowed the analysis of the strength/EMG relationship. Results: In all muscles assessed, there were significant differences in the normalized muscle activation between the intensities of 60 and 70% of the MVC, as well as between 70 and 80% (P<0.05), while there were no differences between 80 and 90% of MVC. In addition, there were significant correlations between strength and EMG signals for the muscles pectoralis major (r=0.43, P=0.04), anterior deltoid (r=0.52, P=0.01), and posterior deltoid (r=0.32, P=0.046). Conclusions: These results suggest that levels of muscle activation near to maximal are obtained at the intensity of 80 of MVC and no additional motor unit recruitment are achieved at 90% of MVC.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"23 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2013-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80047615","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}

However, no study investigated the age of peak swim performance in other disciplines such as individual medley. Objective: To examine the change in the age of peak individual medley performance for both elite female and male Swiss swimmers from 1994 to 2011. Methods: The change in age of peak individual medley performance was investigated for elite female and male swimmers from 1994 to 2011. For comparison, an analysis of freestyle swimming was also performed. Swim speed in 200m and 400m medley, sex and age of the top ten swimmers at national level (Switzerland) were analysed using linear regression and two-way analysis of variance (ANOVA). Results: The age of peak swim speed was (P 0.05). Swim performances improved for both swim styles and distances across years (P ≤ 0.03). Conclusion: The age of peak swim performance in medley and freestyle remained stable and was lower for women than for men in elite Swiss swimmers during the 1994 to 2011 period. Future studies need to investigate the age of peak swim speed in swimmers at international level in other competitive swim strokes.

In ultra-endurance races, athletes face limits in nutrition regarding both energy intake and fluid metabolism. The purpose of this review is to focus on the decrease in body mass, aspects of energy and fluid balance, and exercise-associated hyponatremia in ultra-endurance performance. An ultra-endurance performance lasting 24 hours or longer may lead to an energy deficit of approximately 7,000 kcal per day. This energy deficit may result in a decrease of body mass, including a decrease in both fat mass and skeletal muscle mass. The energy deficit cannot be completely compensated by increasing energy intake. Adequate fluid intake is required during an ultra-endurance performance to prevent dehydration. In case of fluid overload, both exercise-associated hyponatremia and swelling of limbs may occur. Limited fluid intake of approximately 300-400 ml per hour may prevent both exercise-associated hyponatremia and swelling of limbs. In summary, in ultra-endurance performances, an energy deficit seems to be unavoidable, and athletes are at risk to develop both exercise-associated hyponatremia and limb swelling in case of fluid overload.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"97 1","pages":"200-210"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75973335","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}
