Many studies in the past three decades have examined the beneficial effects of omega-3 polyunsaturated fatty acids in diet and supplementation. The effect of polyunsaturated fatty acids, specifically omega-3 and omega-6, on health have been well-studied but most of the study to date has been on animal not plant sources and much less is know about their effects on exercise performance. Additionally, while positive effects have been detected for sedentary populations or those that are at risk, well-trained athletes generally have not had established advantages in taking supplements for omega-3 and omega-6 oils. There is evidence that a specific ratio of omega-6 to omega-3 is most beneficial for the human body with regards to cardiovascular and mental health. In this study, participants randomized to either a plant supplement group (pureform omega; containing Flax, Evening Primrose, Sunflower, Coconut \& Pumpkin oils; Natural Product Number = 80050660) or placebo (isoenergetic sugar pills) will be subjected to both a time trial and a high intensity interval bout, where their performance and power output will be analyzed. Blood lactate and glucose concentration, as well as oxygen consumption and carbon dioxide production will also be examined to determine if there is a change in on fat oxidation after supplementation.

change in cycle ergometer time trial
A 40 Km time trial test on a cycle ergometer will be conducted before and after a 5-week supplementation period
at baseline and 5 weeks after supplementation
change in Aerobic capacity (VO2 max) test
Aerobic capacity will be quantified using an incremental running test on a treadmill. The workload will be increased by increasing the slope (simulating a hill) at a constant speed (6mph)
at baseline and 5 weeks after supplementation
Change in Wingate Anaerobic Test
A 30 second intense effort on a cycle ergometer against a load equal to 9% of body mass. Peak power, mean power, total work and fatigue index will be recorded at the end of each sprint.
at baseline and 5 weeks after supplementation
change in Strength/Endurance test
Number of bench presses completed (rounded to the nearest 1/2 lift) with a 60 kg load and a metromone for pacing control (30 lifts per minute) will be used and rating of perceived exertion (RPE) will be assessed immediately before and immediately after each exercise test using the Borg Scale (analog scale with verbal identifiers)
at baseline and 5 weeks after supplementation
change in Body composition
at baseline and 5 weeks after supplementation
change in Blood lactate
at baseline and 5 weeks after supplementation
change in Blood glucose
at baseline and 5 weeks after supplementation
This group will receive isoenergetic carbohydrate (corn syrup) supplement daily for 5 weeks
This group will receive a plant essential fatty acid food supplement, Pureform Omega® capsules made from Fax, Sunflower, Coconut, Evening Primrose, \& Pumpkin oils, containing a 2.5:1 omega-6 to omega-3 ratio (1.5 g per 70kg body mass plus an additional 0.5 g on exercise days)
This group will receive an iso-energetic corn syrup supplement everyday for 5 weeks
This groups will receive 4 capsules/70kg body mass (Pureform Omega® capsules made from Fax, Sunflower, Coconut, Evening Primrose, \& Pumpkin oils) every day for 5 weeks
