Core session using Redcord equipment and bodyweight
with Tor E. Sandvikmoen – physiotherapist and performance coach.
👉 Co-author (Frontiers in Physiology, 2025):
“The effect of heavy-resistance core strength training on upper-body strength and power performance in national-level junior athletes – a pilot study”
Stronger core is associated with:
– increased force production
– improved movement efficiency
👉 Core muscles = force transfer between upper and lower body
📊 Supported by additional evidence (Sports Medicine, 2022):
“The Effects of Trunk Muscle Training on Physical Fitness and Sport-Specific Performance in Young and Adult Athletes”
– Significant improvements in sprint performance
– Moderate to large effects on agility and muscular endurance
– Significant improvements in muscle power
– Improved sport-specific performance
📊 Data from:
– 31 studies / 693 athletes (11–37 yrs)
