Abstract :There is a growing interest in maximizing CrossFit insert ignore into journalissuearticles values(CF); performance as the sport becomes more economically viable at elite levels. The ability to delineate the physiological demands of the sport of CF allows coaches and athletes to develop more efficacious exercise programming in order to maximize the athlete’s potential for success at the most elite and lucrative levels of competition. There is also a growing interest in increasing health and fitness in the general population as obesity and chronic disease rates continue to rise. Hand grip strength insert ignore into journalissuearticles values(HGS); is an indicator of total body strength, mortality, morbidity and independence among aging adults. Given that CF is the “Sport of Fitness”, it would be of interest to determine the relationship between HGS and CF performance. The current study examined the relationship between CF performance and hand grip strength insert ignore into journalissuearticles values(HGS);. It was hypothesized that CF performance would have a meaningful significant relationship with HGS. Fifteen insert ignore into journalissuearticles values(n=15); female CF participants insert ignore into journalissuearticles values(age 30.9±7.1 years, height 160.3±4.8 cm, body mass 64.5±9.6 kg); of varying experience levels insert ignore into journalissuearticles values(51.9±30.6 months); were assessed for HGS and CF performance measures. The CF performance measures were assessed via a Workout of the Day insert ignore into journalissuearticles values(WOD); comprised of 3 rounds of 30 seconds at each of the following stations: fan bike insert ignore into journalissuearticles values(FB); for maximum calories, air squats insert ignore into journalissuearticles values(AS); for maximum repetitions, sit-ups insert ignore into journalissuearticles values(SU); for maximum repetitions, and burpees insert ignore into journalissuearticles values(BP); for maximum repetitions. Each 30 second work interval was followed by 2 minutes and 30 seconds of rest to ensure full recovery of the phosphagen energy system. Scores were reported as the mean number of repetitions completed across the 3 attempts at each movement station. Individual movements as well as total repetitions were then compared to HGS with Pearson correlation coefficients insert ignore into journalissuearticles values(r);. Sit-up performance demonstrated a positive moderately insert ignore into journalissuearticles values(r=0.44); significant relationship with mean HGS insert ignore into journalissuearticles values(p<0.05);. Neither total WOD performance nor any other individual movement had a significant relationship with HGS insert ignore into journalissuearticles values(p>0.05);. Within the parameters of this study, CF participants exhibited a moderate relationship between HGS and sit-up scores.
