Psychological Outcomes Associated with CrossFit
No full textCrossFit is an exercise program that was theoretically designed to map onto ancestral forms of exercise and movement. Whether CrossFit actually matches the kinds of movements that were regularly implemented by our pre-Agrarian ancestors is up for debate. Assuming that CrossFit, regardless of its actual evolutionary relevance, may have some benefits, the current work examined whether CrossFit is associated with psychological and social benefits to individuals compared with a more traditional exercise regimen (Gold’s Gym). This study included 188 participants, 69 Gold’s Gym members and 119 CrossFit members who completed an online survey. In addition to several questions about their perceptions of their workout experience, this survey asked them to describe their motivations for exercising. They also completed measures of the Big Five personality traits and several demographic measures (such as an index of socioeconomic status (SES)). Results demonstrated that people who attend the two different gyms do not differ from one another on average in terms of SES or basic personality structure. However, those who attended CrossFit emerged as reporting relatively positively in terms of such outcomes as experiencing challenge, obtaining social recognition, and forming affiliative bonds with others. Findings suggested that CrossFit members show higher levels of intrinsic motivation for their exercise regimen compared with those who attend Gold’s Gym. The implications for designing effective exercise regimens are discussed

The paleolithic ketogenic diet may ensure adequate serum magnesium levels
No full textIntroduction
Magnesium plays an essential role in several enzymatic reactions. Its deficiency is known to be widespread and has been associated with a variety of pathological conditions characterized by chronic inflammation and/or oxidative stress. The connection between the metabolism of glucose and magnesium at the cell level is well-established. We hypothesize that magnesium deficiency in chronic conditions is primarily due to Western type carbohydrate based metabolism. In previous case studies we have shown that magnesium levels are normal on the paleolithic ketogenic diet. Here we assessed magnesium levels in a larger sample (n=50) to address whether the paleolithic ketogenic diet is able to ensure normal blood magnesium levels.
Materials and Methods
To assess magnesium levels in patients and healthy controls on the paleolithic ketogenic diet in a larger sample, we retrospectively analysed laboratory data obtained from 50 patients/subjects who were following the diet and were also not taking magnesium or other supplements. Correlation calculation was performed between magnesium and glucose levels.
Results
We found magnesium levels to be in the normal range in all but one patient/subject. There was a significant inverse correlation between glucose and magnesium levels.
Discussion
Our results indicate that the paleolithic ketogenic diet ensures normal magnesium levels in various pathological conditions as well as in healthy subjects. We believe that the high prevelance of magnesium deficiency reported earlier for a variety of chronic conditions is correlated with carbohydrate-based Western type nutrition rather than that of the chronic condition itself. We discuss underlying mechanisms
