Does In-The-Moment Strategic Self-Talk Affect Volleyball Officials' Refereeing Efficacy?

Self-talk in sport is a valuable self-help tool for regulating one's emotions, thoughts, and actions. This study aimed to examine whether the use of in-the-moment, strategic self-talk enhances volleyball officials' efficacy beliefs about their refereeing decisions in match-play scenarios. The relationship between officials' general self-talk tendencies and commonly perceived refereeing efficacy in recent matches was also investigated.

Effect of fasting on the composition of plasma lipoproteins in cholesterol-fed diabetic rabbits.

Cholesterol-fat feeding is associated with unusual alterations in the composition of plasma lipoproteins in alloxan-diabetic rabbits. In the present study plasma lipoprotein lipid and apoprotein composition was studied before and after 48 hr of fasting in cholesterol-fed diabetic and control rabbits in order to further characterize these alterations. Compared with control rabbits, the diabetic rabbits had similar plasma cholesterol levels, but 100-fold higher triglyceride levels prior to fasting.

Reduction of coronary atherosclerosis by moderate conditioning exercise in monkeys on an atherogenic diet.

All available evidence that exercise may protect against coronary heart disease is circumstantial, and direct evidence is difficult to obtain in human beings. Therefore, we studied the effect of moderate conditioning with treadmill exercise on developing coronary-artery disease in monkeys on an atherogenic diet. Physical training was demonstrated by slow heart rates.
