Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

Unfortunately for many soldiers, running, pushups, and sit-ups address endurance, but do little to train mobility and strength. To meet the demands of their work and help avoid overuse injuries, a training program for soldiers should include mobility, strength, and endurance components.

Few strength coaches have shaped sport performance like Al Vermeil — the only strength coach to earn championship rings in both the National Football League (NFL) and National Basketball Association (NBA). In this Gatorade Performance Partner Special Episode, Vermeil shares how a career built on explosiveness, adaptability, and relentless curiosity has transformed teams at every level. From advancing plyometrics and Olympic lifts in the 1970s to creating the performance pyramid and the innovative “time machine” testing system, his methods have influenced generations of coaches and athletes worldwide. Known for blending timeless principles with fresh, actionable ideas, he explains how mechanics, group management, and collaboration create consistent results and lasting trust. Along the way, Vermeil offers rare perspectives on coaching longevity, revealing how his adaptability and curiosity have kept him learning — and lifting — into his 80s. Gain practical insights to keep explosiveness central, integrate performance science, and strengthen your long-term coaching impact.
