Determination of the best recovery based on muscles synergy patterns and lactic acid

The determination of the best recovery after an anaerobic exercise is an important challenge for professional athletes. This study compared and analyzed three methods that are often used in professional teams included: 1. Cold water pool 2. Use the massager 3. Running with 40 to 50 percent of heart rate. Methods: In this work recovery the 15 minutes recovery is done immediately after doing exercise. The impact of a particular method of recovery is quantified via lactic acid in the blood after the recovery and the synergy patterns of muscle activity. In each method, Biceps femoris, rectus femoris, tibialis anterior, lateral gastrocnemius muscles were analyzed. Results showed that there were synergy patterns in two running and ice methods, because maximum errors between basis vectors in all of the subjects were 0.13 and 0.18 respectively and Standard deviation of maximum MSE errors for all subjects is 6 (MSE index), whereas in massage recovery synergy has not been recognized because minimum error between basis vectors in all of the subjects was 4.29 and Standard deviation of maximum MSE error for all subjects is 4. Running has the best result in evacuating lactic acid. However, result in the ice method is similar to running

The Impact of Health Education based on the Health Belief Model on Improving Osteoporosis preventive Behavior among Women

Background: In all populations, bone mass decreases with age, so the researchers in this study sought to study the application of the health belief model (HBM) for adopting preventive behaviors on osteoporosis among women. Methods: This was a quasi-experimental research conducted on 64 middle-aged women (32 in test and 32 in control group). Data collection tools were a questionnaire based on HBM model with demographic questions, the food frequency questionnaire and the standard questionnaire of physical activity. After confirming the content validity and reliability, questionnaires were completed before and 6 weeks after the intervention. Data analysis was conducted using descriptive statistics (frequency, percentage, mean ± SD) and analytical statistics (correlation coefficient, paired t- test and covariance) and through SPSS 16 at the significance level of 0.05. Results: Before the intervention, the mean score of HBM model constructs were not significantly different between the two groups. After the intervention, and by controlling for confounding variables the two groups showed significant differences in variables of knowledge, perceived severity, perceived self-efficacy, cues to action, perceived benefits and Calcium intake (p< 0.05), while they showed no significant difference in regard to constructs of perceived susceptibility, perceived barriers and physical activity. Conclusion: The use of health belief model was effective in adopting the prevention of osteoporosis and improving calcium intake in women, but it did not lead to the desired results in regard to improving physical activity behavior

Sensory characteristics and lipid composition of white amur (Ctenopharyngodon Idella) fed different diets

Two fish diets, trout chow pellets (A) and alfalfa pellets (P), were evaluated as to their effects on growth, lipid level and compo-sition, fatty acid (FA) composition of polar and neutral lipids, and sensory characteristics of grass carp (Ctenopharyngodon idella). During the 6 month feeding experiment, fish fed A gained 661 g/fish compared to 358 g for fish fed P. In addition, total lipid con-tent in fish fed A increased from 1.84 to 3.72% in 4 months time, but remained approximately the same in fish fed P (P\u3c 1.0%) across feed-ing times. Three phospholipid classes: sphingomyelin (6 to 13%), lecithin (55 to 63%), and cephalin (25 to 35%) were affected by feed-ing time (P\u3c0.05). Nineteen FA were found in the phospholipids: 14:0, 16:01, 16:0, 16:1, 18:0, 18:1, 18:11, 18:2ω6, 18:3ω6, 18:3ω3, 20:1, 20:2, 20:3, 20:4ω6, 20:5ω3, 20:5ω6, 22:5uω3, 22:6ω3, and 24:1. Significant differences between diets were found in the percentages of 14 acids, and feeding time also significantly affected the levels of these acids. All of the previous FA except 16:01 plus 9 additional 16:11, 17:0, 17:1, 20:0, 22:1, 23:0, 24:0, 24:4 and an unknown, were found in the neutral lipids. Significant differences between diets were found in the percentages of 18 acids in the neutral lipids, and feeding time significantly affected the levels of 19 of the acids. Compared with fish fed P, fish fed A had higher levels of monounsatur-ated FA (MONO) and lower levels of omega-6 polyunsaturated FA (PUFA) in both neutral and polar lipids; there were higher levels of saturated FA (SAT) and omega-S PUFA in the phospholipids but lower levels of SAT and omega-3 PUFA in the neutral lipids. Compared to P, A had lower percentages of SAT (40.9 vs. 51.1), omega-6 PUFA (12.1 vs. 18.2), and omega-3 PUFA (15.8 vs. 24.7) and a higher percentage of MONO (31.0 vs. 5.3). There was no significant difference between the flavor of grass carp fed P (3.6) and that of catfish (3.7), but the panel (n = 93) scored the flavor of grass carp fed A (3.4) lower than that of catfish (P\u3c0.06). They also found no significant differences in texture among the three fish samples. Compared with catfish acceptability (3.6), grass carp fed P tended to have lower acceptability (3.4), but grass carp fed A a significantly lower acceptability (3.3). The main reason given for scoring the acceptability of grass carp lower than that of catfish was the presence of small bones in the fillets. This indicates that either grass carp must be bigger at market-size than those in this study (1585 g) or the bones must somehow be removed

GAIN ENHANCEMENT OF DIELECTRIC RESONATOR LOADED WAVE-GUIDE ANTENNAS WITH DIELECTRIC OVERLAYS

The gain characteristics of a dielectric resonator loaded coaxial probe fed circular waveguide antenna (DRLWA) with overlaying parasitic discs have been investigated experimentally. Results indicate that, when properly spaced, the overlays can enhance the gain by more than 6 dB. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down

Growth and organoleptic qualities of grass carp fed experimental diets

The growth of two different sizes of grass carp were studied in laboratory feeding experiments. Experimental diets included trout chow, bermuda grass pellets, and sudan grass; fish were fed at three feeding rates, 2.5, 5, and 10% of body weight. The fish that were fed trout chow showed excellent growth of small and large fish at 2.5, 5, and 10%. Bermuda grass produced good growth only in large fish at the 2.5% level and better growth at 5%. Small fish lost weight when fed bermuda grass at the 5 and 10% rates. This was probably due to the smaller fish being unable to consume the large pellets. The fish fed sudan grass at 2.5% body weight also lost weight during the six-week feeding trial. Organoleptic comparisons indicated that there was a significant difference in the taste preference of grass carp fed bermuda grass and trout chow. The panelists preferred fish fed bermuda grass more than those fed trout chow. There was no significant difference in the taste preference among grass carp fed bermuda grass, trout chow, and sudan grass when compared to channel catfish

Sir William Jones and the Shahnameh

The second half of the eighteenth century was a period of transition in European aesthetics. It was also a time of increasing contact between Europe and Asia. The rise of Oriental literary scholarship was a natural outgrowth of the public interest in things Oriental. While the earlier part of the century had sought to reaffirm the basic tenets of the Enlightenment with the help of its indirect knowledge of the Oriental literatures, the later generations became increasingly fascinated with the new possibilities of the literary heritage of the East. The Shahnameh first attracted the attention of the eighteenth-century Orientalists such as Sir William Jones as the supreme example of Oriental epic poetry. The present essay proposes to study Jones's conception of Persian literature and his remarks on the poetry of Firdawsi, as well as his fragmentary translations of the Shahnameh
