Understanding how the body adapts to the overload of aerobic exercise is critical to designing effective exercise training programs, monitoring exercise responses and progress, and assessing training outcomes.

This excerpt from NSCA’s Essentials of Sport Science briefly explains the force-velocity-power profile and how it can give strength and conditioning coaches a more holistic view of athletes.

Kelly Dormandy, Assistant Athletics Director for Sports Performance at Loyola Marymount University and Head Strength Coach for the Los Angeles Sparks Women’s National Basketball Association (WNBA) team, talks to the NSCA Coaching Program Manager, Eric McMahon, about championship culture. Topics under discussion include constantly seeking new challenges, training WNBA athletes, and being proactive about networking in the field.

The VO2max test is the most effective measurement of the body’s ability to deliver and use oxygen for producing energy that can be used by the muscles. VO2max (i.e., maximum aerobic power) simply stands for the maximal volume of oxygen that can be used.

The primary aim of this study was to systematically compare the effectiveness of blood flow restriction training (BFR) versus traditional resistance training (TRT) to improve muscle size in healthy adults. Secondary outcomes were improvements in muscle strength and endurance. We performed a systematic searchwithmeta-analysis. Using predetermined criteria, 541 unique articles were identified through databases and bibliographies. After screening titles, abstracts, and full texts, 20 articles were included in the review. All 20 articles evaluated muscle hypertrophy, 19 evaluated strength, and 1 evaluated endurance in response to BFR and TRT. Data from 10 articles were included in the meta-analysis. In the qualitative analysis, TRT and BFR increased muscle size without differences between conditions for at least 1 hypertrophy outcome in 13 studies, and TRT or BFR differentially improved hypertrophy in 5 studies. TRT and BFR increased strength without differences between conditions for at least 1 outcome in 15 studies, and TRT or BFR differentially improved strength in 9 studies. Results from the meta-analysis indicate no differences in muscle size (ES 5 0.045, 95% CI [20.278 to 0.367]) or strength (ES520.149, 95% CI [20.439 to 0.141]) improvements with BFR versus TRT. Practitioners can implement BFR training to increase muscle size and strength as appropriate, especially for training periods of 8 weeks or longer.
