Caffeine For More Reps To Failure
Caffeine has been shown to promote athletic performance under a variety of conditions. A number of studies have tested its effect on endurance athletes, and now weight room warriors have research to consider. The study was published in The Journal of Sports Medicine and Physical Fitness.
Fourteen recreational male weight lifters in their early 20s were given 5 mg of caffeine per kg of body weight or a placebo before performing 3 sets on the bench press and leg press. Caffeine helped subjects perform more reps to failure, with 11.6% greater volume on the bench press and 19.1% more reps on the leg press. Caffeinated subjects also reported a higher level of physical and mental readiness.
How Beta-Alanine Boosts Endurance
Muscle carnosine content can be elevated by supplementing with beta-alanine. That’s one reason why it’s such a popular ingredient in pre-workout products. Unfortunately, it doesn’t work the same for everyone, as a study published in the journal Medicine & Science in Sports & Exercise suggests.
Researchers had 24 active men supplement with 6.4 grams of beta-alanine per day for 24 weeks. Some received a placebo. Every 4 weeks, muscle carnosine levels were measured, and carnosine content increased at every examination for supplementing subjects. They also showed an increased capacity for high-intensity cycling compared to subjects who received a placebo. But there was a lot of individual variability in muscle carnosine content, ranging from 31.79 to 63.92 mmol per kg of muscle mass.
