Skeletal Muscle Glycogen

Skeletal muscle glycogen (SMG) stores in highly glycolytic activities regulate muscle contraction by controlling calcium release and uptake from sarcoplasmic reticulum, which could affect muscle contraction. Historically, the assessment of SMG was performed through invasive and non-practical muscle biopsies. In this study we have utilized a novel methodology to assess SMG through a non-invasive high-frequency ultrasound. Nine MLS professional soccer players (180.4 ± 5.9 cm; 72.4 ± 9.3 kg; 10.4% ± 0.7% body fat) participated. All followed the nutritional protocol 24 h before the official match as well as performing the same practice program the entire week leading to the match. The SMG decreased from 80 ± 8.6 to 63.9 ± 10.2; p = 0.005 on MuscleSound® score (0–100) representing a 20% ± 10.4% decrease in muscle glycogen after match. Inter-individual differences in both starting glycogen content (65–90) and in percentage decrease in glycogen after the match (between 6.2% and 44.5%). Some players may not start the match with adequate SMG while others’ SMG decreased significantly throughout the game. Adequate pre-match SMG should be achieved during half-time and game-play in order to mitigate the decrease in glycogen. Further and more ample studies are needed before the application of this technology.

Kombucha Tea

Kombucha tea beverage obtained by fermenting sweetened green tea for 12 days with Acetobacter xylinum and Saccharomyces which produce various kinds of organic acids, vitamins, and acts as a probiotic. The role of kombucha tea as a growth promoter is to that improve the metabolic process in the digestion of broiler chickens, so that nutrients can and fulfilled optimally for growth and development. The aim of this research was to analyze the sceletal muscle glycogen glycogen (Gallus gallus) after treat with kombucha tea in drinking water. Kombucha tea used is the result of fermentation of green tea for 12 days. This research used DOC chickens (Day Old Chicken) as much as 20 randomly divided into 4 treatments with concentration ie 0%, 10%, 20%, and 40% kombucha tea in drinking water for 32 days. The variables measured were skeletal muscle glycogen levels, body weight, feed consumption and drink consumption. The data obtained were analyzed using ANOVA followed by Duncan Test with 95% confidence level using SPSS 17.0 software. The results of this study showed that kombucha tea on skeletal muscle glycogen and feed consumption showed no significant difference, while on body weight and drink consumption showed significantly different results. Based on the results of the study, it can be concluded that giving kombucha tea in drinking water to a concentration of 40% has not been able to affect the skeletal muscle glycogen in broiler chickens. Key words: Kombucha tea, broiler chicken, glycogen skeletal muscle
