Resistance training frequency (2x vs 4x per week) does not significantly alter patellar tendon morphological adaptations (Cross-Sectional Area or Length) when volume is equated.
Do not expect your tendons to get thicker (hypertrophy) from 8-12 weeks of resistance training, regardless of whether you train 2 or 4 times a week. Focus on strength gains, which can occur without visible morphological changes in this timeframe.
ModerateRefutesMEDIUM confidence
In conclusion, the leg extension exercise performed 2 vs 4x/week induces similar patellar tendon morphological responses.
Why this rating
Small sample size and short duration for morphological changes.
