Fitness Articles Important research concerning a personal trainer's educational background
Malek MH, Nalbone DP, Berger DE, et al. Importance of health science education for personal fitness trainers. J Strength Cond Res. 2002 Feb;16(1):19-24.
A survey of 115 health fitness professionals revealed that a bachelor's degree in the field of exercise science and possession of American College of Sports Medicine or the National Strength and Conditioning Association certifications as opposed to other certifications were strong predictors of a personal trainer's knowledge, whereas years of experience was not related to knowledge.
The influence of direct supervision of resistance training on strength performance
Mazzetti SA, Kraemer WJ, Volek JS, et al. The influence of direct supervision of resistance training on strength performance. Med Sci Sports Exerc. 2000 Jun;32(6):1175-84.
Twenty moderately trained men were randomly assigned to either the supervised group or unsupervised group who performed identical resistance training programs using free-weight and variable-resistance machine exercises. The study showed the directly supervised men demonstrated a greater rate of training load increase and magnitude which resulted in greater maximal strength gains compared with unsupervised training group.
Super Slow Training Does Not Metabolize More Calories than Traditional Resistance Training
Hunter GR, Seelhorst D, Snyder S. Comparison of metabolic and heart rate responses to super slow vs. traditional resistance training. J Strength Cond Res. 2003 Feb;17(1):76-81.
Results showed the traditional resistance training program had a high energy cost than "Super Slow" training program. The "Super Slow" program was significantly lower in total work and relative exercise intensity when compared to the traditional resistance training program. Intensity was 2.6 times greater, and over four times more work was performed with the traditional resistance training program. This study does not support the claims of proponents that "Super Slow" is a superior method for energy expenditure. Individuals looking to lose weight through resistance training may do better to find a program that utilizes more energy than a "Super Slow" program. | Injury Prevention Neuromuscular control training programs reduce noncontact ACL injury rates in female athletes Grindstaff TL, Hammill RR, Tuzson AE, Hertel J. Neuromuscular control training programs and noncontact anterior cruciate ligament injury rates in female athletes: a numbers-needed-to-treat analysis.
J Athl Train. 2006 Oct-Dec;41(4):450-6. The results of the review indicate that to prevent one non-contact ACL injury 89 individuals need to participate in the prophylactic training program. Individuals who participate in prevention programs are able to reduce their risk of non-contact ACL injury by 70%. | Youth Fitness National Strength and Conditioning Association's
