This study compared the effectiveness of the single-leg Roman chair hold exercise with the Nordic hamstring curl exercise in athletes with previous hamstring injuries.

This excerpt from NSCA’s Essentials of Personal Training, Second Edition briefly reviews the role of oxygen uptake in exercise.

It is well known that moderate exercise during pregnancy benefits maternal and fetal well-being. The benefits of more vigorous exercise for pregnant women are less clear. The boundaries of safe exercise during pregnancy remain a matter for continued research, which is important to the growing number of female athletes who plan on becoming pregnant. The purpose of this article is to discuss the existing research related to the physiological concerns of the pregnant endurance athlete specifically. Because endurance training includes prolonged and repetitive exercise bouts at varying intensities, topics will include the effect of high-intensity exercise on uterine blood flow and thermoregulation, metabolic, and musculoskeletal changes in pregnancy.

This excerpt from the book Exercise Technique Manual for Resistance Training, 3rd Edition, discusses the proper technique for the glute ham raise exercise.

Is the squat or hip thrust a better exercise for increasing jump and sprint performance? The results of this study support the force vector theory.

This article examines the effects that are commonly experienced by people who have undergone knee replacement surgery as well as the exercises that can help them regain functionality.

This excerpt from NSCA's Guide to Sport and Exercise Nutrition briefly discusses micronutrients and their role in optimal athletic performance.

A study that investigated the effect of modified German volume training on muscular hypertrophy and strength concluded that the modified German volume training program is no more effective than performing five sets per exercise for increasing muscle hypertrophy and strength. To maximize hypertrophic training effects, it is recommended that 4 – 6 sets per exercise be performed.

Understand the overall process of exercise and recovery and learn to identify the four key areas of stress and recovery. In this session from the 2017 NSCA Coaches Conference, Michael Naperalsky also explains how to classify various modalities and strategies as “effective,” “promising,” or “inconclusive,” and how to measure recovery.

Joe Kenn, MA, CSCS,*D, RSCC, spoke at the NSCA's National Conference about training and the impact of training in a fatigued state.
