It also found no significant changes in total cholesterol, LDL-C, non-HDL cholesterol, or triglycerides, and regular submaximal interval exercise without those modifications did not adversely affect the lipid profile.

The device showed high accuracy and was presented as a promising wearable platform for metabolic monitoring, diabetes care, nutritional tracking, and disease monitoring.

It suggests that understanding motivation patterns may help tailor exercise interventions for this clinical population.

The authors report that the model can estimate ACL loading from movement and muscle-activation signals, which may support safer exercise screening and biomechanics research.

Strength gains were specific to the modality trained, meaning free-weight training improved free-weight strength more and machine training improved machine-based strength more.
