Energy And Carbohydrate Intake Are Associated With Quadriceps Rate Of Torque Development Following ACL Injury

Abstract

RESULTS:Average energy consumption decreased from pre-surgery to post-surgery (1797.3 ± 588.9 vs. 1587.8 ± 604.9, respectively; p=0.029). Comparisons pre-and post-surgery for weight (74.9 kg ±18.0 vs. 74.5 ± 18.5), kcal/kg (24.8 ± 7.5 vs 22.3 ± 8.8), and protein g/kg (0.99 ± 0.35 vs. 0.97 ± 0.44) did not show differences. HEI-2015 was significantly lower in teenagers pre-and post-surgery compared to the US average of 53 for Americans age 2-19 (42.4 ± 8.5; p <.001; 42.7 ± 9.8; p <.001). Adult participants' HEI was significantly lower than the US average of 59 only after ACL reconstruction (53.2 ± 13.3; p= 0.073; 50.5 ± 13.2; p= 0.011). Children had significantly lower HEI-2015 than adults before reconstruction (42.4 ± 8.5 vs 53.2 ± 13.3; p=0.007) but not after (42.7 ± 9.8 vs 50.5 ± 13.2; p=0.057). CONCLUSION: On average, energy intake decreases following ACL surgery in young participants. Future research should address links between diet quality, reduced energy intake and recovery following ACL surgery.
