摘要：Problem statement:High intensity functional training is a popular training modality where individuals complete as many repetitions as possible in sequence to solicit maximal fatigue in a workout. Despite the popularity of these programs it is unclear whether this approach improves fitness more than a traditional resistance training program.Purpose:Thus,we aimed to understand whether muscular,aerobic and anaerobic fitnesswere improved via high intensity functional training compared totraditional resistance training.Approach:Thirtyhealthy male and femaleparticipants (23.2±3.2 years) were randomly assigned to free exercise,high intensity functional training,or traditional;n=10.High intensity functional training andtraditional workouts were supervised and training volume was similar while the free exercise group maintained normal exercise across the 6 weeks.The same test batterywas performedpre-post and additional physical activity recorded for each group. Results:Significant post training group differences were: high intensity functional training lower bodyanaerobic power was less than free exercise and traditional type training;and upper body muscle endurance was greater in high intensity functional training compared to traditional type training.There were significant improvements in all muscle strength measures for both types of training groups and aerobic power improved in the high intensity functional training group (p<0.05).However,the free exercise group also improved in many post assessments which implies a learning effect. Further,the lack of improved anaerobic fitness in either training group indicates excessive accumulated fatigue. Conclusions:Given our results,high intensity functional training or traditional will improve muscle strength and high intensity functional training likely improves aerobic power and upper body muscle endurance more. However,both typesof trainingare very intense and may lead to undue fatigue in recreationally active adults.
