Suggestions
(i) Larger sample size: Conduct studies with a larger sample size to increase statistical power and enhance the generalizability of the findings. (ii) Long-term interventions: Implement longer intervention periods to investigate the effects of TC exercise programs on BMD over extended durations. (iii) Stratification based on baseline characteristics: Ensure baseline characteristic homogeneity by stratifying participants to minimize potential confounding factors. (iv) Adherence monitoring: Monitor participants' adherence to TC exercise interventions and investigate factors influencing adherence rates. (v) Diverse population inclusion: Expand the study population to include individuals with different demographic characteristics to improve external validity. (vi) Alternative outcome measures: Consider using additional measurement techniques or incorporating multiple outcome measures to provide a comprehensive evaluation of BMD and its changes.
