Key result
The second lactate threshold significantly correlated with 40-km cycling performance in both sexes, but only 82% of women sustained LT2 power output for 30 minutes compared to 100% of men.
Why the study?
Does the relationship between the second lactate threshold and endurance performance differ between male and female competitive cyclists?
Observational (n=22)
Does the relationship between the second lactate threshold and endurance performance differ between male and female competitive cyclists?
Effect estimate: r = -0.63 to -0.75 (women); r = -0.69 to -0.77 (men)
p-value: p=< 0.01-0.05
While LT2 correlates with endurance performance in both sexes, it overestimates sustainable 40-km time trial power in women, highlighting the need for sex-specific training recommendations.
No takes yet. Share an insight, caveat, or question.
LT2 may overestimate sustainable power in female cyclists; leaves open whether sex-specific thresholds improve training.
Hoffmann et al. (2018) conducted an observational in Competitive cyclists and triathletes (n=22). Lactate threshold (LT2) assessment vs. Men vs Women was evaluated on Correlation of LT2 with 40-km cycling performance (r = -0.63 to -0.75 (women); r = -0.69 to -0.77 (men), p=< 0.01-0.05). The second lactate threshold significantly correlated with 40-km cycling performance in both sexes, but only 82% of women sustained LT2 power output for 30 minutes compared to 100% of men.
