If one is a very active individual or a competitive athlete, what are the positives and negatives of donating blood, platelets, and plasma?

This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.

Emerging evidence suggests that omega-3 fatty acids may play a beneficial role in preservation of, and increases in, skeletal muscle mass. This is of particular relevance to the elderly who display age-related declines in muscle mass and function.

Congratulations to the 2020 NSCA Award Winners!

The National Strength and Conditioning Association (NSCA) is proud to announce the recipients of the organization’s 2024 Career and Service Awards. Given annually, the distinguished Career Awards honor individuals who have made significant contributions to the strength and conditioning community throughout their careers.

Abstract submissions are open yearly from November to March (exact dates change annually). See the Abstract Submission and Presentation Guidelines for more information (below). Research abstract presentations are an opportunity to present current research findings to researchers and strength and conditioning professionals at the NSCA National Conference.
