Does Tennis need many like Dr. Jim Loehr and Dr. Jack Groppel?

by Fernando Segal (4/6)

They are truly pioneers, Hall of Famers of Human Performance. They took the understanding of people's development in multiple areas to another level.

In the world of high performance, whether in sports, business, or leadership, few names carry the scientific weight and transformational impact of Dr. Jim Loehr and Dr. Jack Groppel.

Together, they redefined the way we train for excellence, not focusing solely on time or effort, but on energy, recovery, purpose, and the whole human being.

Through decades of research and applied science, Loehr and Groppel co-founded the Human Performance Institute (HPI), a revolutionary project rooted in performance psychology, exercise physiology, nutrition, and behavioral science. They broke down the walls between disciplines to create one of the most effective training models ever developed.

They taught that true high performance is multidimensional. Their model, grounded in the periodization of energy, changed the way elite athletes trained and how Fortune 500 executives led their teams. Their work expanded from Olympic champions and Tennis Grand Slam winners to global CEOs, medical professionals, military leaders, and key leaders.

Dr. Jim Loehr, a world-renowned performance psychologist, championed the importance of personal character and emotional resilience. His books such as The Power of Full Engagement and Mental Toughness, as others, outlined how our inner values shape outer performance.

Dr. Jack Groppel, an expert in bioengineering and applied physiology, brought a scientific lens to energy management and performance systems. His clarity in connecting science with action made the methodology accessible and effective across all domains with multiple book's published.

Their combined work made a resounding impact. They showed that success is not just about training harder, but training smarter, anchored in purpose and recovery.

Dr. Jack Groppel said "We don't get energy from time, we get energy from purpose. Purpose fuels everything."

At the core of their philosophy lies a profound truth: peak performance is not about doing more, is about becoming more.

.

Their legacy is in books, speeches, or accolades, but more it's in hundreds of thousands of lives transformed by a system that views performance as a full human journey. They built leaders.

They are with us now. Dr. Jim Loehr and Dr. Jack Groppel, we're reminded that leadership begins with self-mastery, and that every coach, executive, teacher, and player has the power to grow from the inside out.

Tennis means a global culture, a movement, a force for growth. We need a revolution of values, structure, and purpose in each next visionary, builder, and true leaders of tennis world like them. Many thanks Jim and Jack!!

We can do it!
