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

This article applies LTAD principles to guide the process of generating an athletic profile (part 1) and sample program design (part 2) for a middle school athlete and a high school athlete.

Hear from University of Connecticut (UCONN) Director of Football Strength and Conditioning, Matt King, as he reflects on milestones and mentors along his decade-plus coaching journey with NSCA Coaching and Sport Science Program Manager, Eric McMahon. King discusses how his early exposure to strength and conditioning as a high school athlete informs the training-age and level-based training approach of UCONN’s football team. Episode highlights include a look into UCONN’s highly collaborative sports performance department, tips for navigating marriage and children in a career with long-hours, and discussion about the National Collegiate Athletic Association (NCAA) Transfer Portal.

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.

Growth happens when you go all in, or as Brittany Wiebe says, “full send.” As Head Strength and Conditioning Coach of women’s basketball at the University of Oregon, she shares her people-first, evidence-based approach to maximize performance, minimize risk, and positively impact each individual. Using reverse engineering and fundamental principles, Wiebe describes programming around the big seven movements, progressive overload, and objective and subjective feedback. She reflects on her path through Kenya, Dubai, and the Dominican Republic, gaining exposure to athletes across sports, backgrounds, and abilities. Logistical challenges, like language barriers and limited resources, strengthened her adaptability and creativity. Wiebe believes weight room culture starts the moment you walk in. Her strategies — from high-energy greetings to rallying around big lifts — remind coaches that intent begins with environment. She challenges coaches to step outside their comfort zones, say “yes” to opportunities, and bring the same intensity to their development that they demand from athletes.
