Athletic Training: Running Pace, Maxes & Macros Guide

📚 Overview

Athletic performance improves fastest with structured, measurable progression. Using mathematical pace splits for endurance, percentage-based barbell loads, and macro targets gives you predictable fitness results and minimizes injury risks.

📐 Running Pace & Brzycki 1-Repetition Maximum (1RM)

Where reps performed is between 2 and 10 to maintain accurate 1RM estimation.

🔢 Worked Example

Scenario: An athlete bench presses 100 kg for 5 completed repetitions.

• Weight: 100 kg
• Reps: 5

1. Denominator = 1.0278 - (0.0278 × 5) = 1.0278 - 0.139 = 0.8888
2. Estimated 1RM = 100 / 0.8888 = 112.5 kg

💡 Pro Tips

• For endurance running, compute pace splits in seconds first before converting back to minutes and seconds.
• Active resistance trainers should aim for 1.6 to 2.2 grams of protein per kilogram of body weight daily for muscle protein synthesis.
• Warm up thoroughly with progressive sub-maximal weights before attempting high-percentage strength lifts.
• Use our Heart Rate Zone calculator to target aerobic base building (Zone 2) vs threshold work (Zone 4).
