About this study
Official title: Effects of Cross Training on Flexibility, Endurance and Speed Among Sprinters
CrossFit is one form of Resistance Exercise that is recognized as a high-intensity program that combines elements of mobility, technique, and strength and has seen increasing popularity in recent years. CrossFit workouts often incorporate Olympic lifts and elements of gymnastic exercises using handstands and rings. A large part of CrossFit workouts also consists of the "workout of the day" or "WOD," where workouts are performed for the best time or performed in the "as many rounds as possible" style and are completed in a group environment, with some workouts performed as a shared workload. The social nature of CrossFit, in addition to the annual 'CrossFit Games', which include national qualifying workouts and regional competitions, is what has led to CrossFit being described as the "Sport of Fitness". Competitors who complete all workouts and rank high enough will progress to the next stage of the competition. Regardless of which stage, it is expected that each workout will consist of a set of challenges that will require some combination of strength, power, endurance, and/or sport-specific skill.
By examining the effects of cross-training on flexibility, endurance, and speed, this study aims to provide a comprehensive understanding of how a diversified training regimen can contribute to the overall athletic development of sprinters. The findings could lead to improved training strategies that enhance performance and longevity in the sport.
