The Claim

In trained males, strength-type and hypertrophy-type resistance workouts are associated with significantly greater elevations in blood lactate concentration (+3.65 mmol/L and +6.02 mmol/L, respectively) compared to cluster-type workouts, indicating higher metabolic stress in traditional training regimens.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

When trained men do certain types of weightlifting workouts, their bodies produce more lactic acid compared to other workout styles, which means their muscles are working harder and under more stress.

What the research says

1 study
  1. Study: The impact of repetition mechanics on the adaptations resulting from strength-, hypertrophy- and cluster-type resistance training

    The study found that traditional strength and muscle-building workouts caused much higher lactate (a sign of workout stress) than cluster workouts, exactly as the claim said.
