Medium Chain Triglyceride (MCT)- based supplements have increased cognitive function in general and specific functional realms. Can an MCT complex improve mental focus in sports with a high, active cognitive component? This pilot investigation tested whether the proprietary MCT complex utilized could result in positive gains in mental focus or perception of enhanced energy on the course. Each of the ten subjects played a 9-hole round using a motor cart, pushcart, carry bag, or electric trolley (which simulated playing with a caddie) while wearing a portable metabolic system to determine baseline energy expenditure, mental focus, and score baseline. Data points recorded and averaged included the volume of oxygen used per minute total (VO2/L/min), oxygen used per kg of body weight per minute (VO2ml/kg/min), converted to kcal per hour, and heart rate. A 10-point mental focus scale had golfers rating tee shots, second through fourth shots, and the short game from 100 yards in. Using their preferred mode of transport and play, the subjects completed one more, 9-hole round after once-daily consumption of the supplement for seven days. The average rating of mental focus and perceived energy increased from a level of 5.77 to 7.22 out of 10, statistically significant at P= 0.0120. Actual play scores decreased from 10.8 to 8.9 over par for the 9-hole rounds, trending positively. This initial trial suggests that a proprietary MCT complex can improve actual golf performance and the golfer's perceptions of focus and energy regardless of which mode of transport and play is used.
