Summary
This study found that phase angle (PhA), a health indicator, correlates positively with body composition and strength in male gamers. Nutritional intake varied, with protein and carbohydrate levels outside recommended ranges.
Area of Science:
- Sports Science
- Nutritional Science
- Human Physiology
Background:
- Gaming is a global phenomenon, yet the physiology of gamers remains understudied.
- Understanding gamer health is crucial due to their increasing population and engagement.
Purpose of the Study:
- To physiologically characterize Portuguese gamers.
- To investigate correlations between body composition, strength, and nutrition using phase angle (PhA).
Main Methods:
- Evaluated 35 male gamers for anthropometry, body composition (DXA, BIA), handgrip strength, and nutritional intake.
- Utilized dual-energy X-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA) for detailed body composition analysis.
- Assessed nutritional status via a three-day food record.
Main Results:
- Gamers' protein and carbohydrate intake deviated from Acceptable Macronutrient Distribution Ranges.
- Phase angle (PhA) showed positive correlations with total body water (TBW), intracellular water (ICW), handgrip strength, bone mineral content (BMC), and fat-free mass (FFM).
- Phase angle (PhA) demonstrated negative correlations with absolute, percentage, and visceral fat mass.
Conclusions:
- Phase angle (PhA) is a significant predictor of body composition in male gamers.
- Findings suggest PhA can serve as an indicator of health and performance in this population.
- Further research is warranted to explore nutritional interventions for gamers.

01:27Exercise and Muscle Performance
1.6K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:27Signs of Puberty
606
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

01:12Coefficient of Correlation
6.4K
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
