Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Osteoporosis is a major contributor to loss of independence due to bone fractures and resulting hospital treatments lead to significant morbidity. While pharmacological treatments can reduce consequences of osteoporosis, there is a pressing need for non-pharmacological interventions to improve bone health across the life-course and to reduce likelihood of age-related bone disease.

This study will allow us to determine whether synergistic potentiating effects on bone metabolism are observed in humans in relation to the timing of food ingestion and what recommendations can be made to people with respect to food ingestion and exercise to obtain the maximal bone benefits from aerobic exercise. Furthermore, if we can identify interventions that potentiate bone's response to aerobic exercise in younger adults, then such interventions may have the ability to maximise bone mass in younger adults so that with ageing, the additional bone mineral density and improved bone microarchitecture would extend the time before osteoporotic "fracture thresholds" are reached. Therefore, understanding the bone metabolic response to exercise following fasting and feeding in younger adults is important.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

In this three-arm randomised crossover study, sixteen young adult men (age: 28 ± 4) will be recruited in good physical condition. Participants will be exercised following a 12-hour overnight fast (FAST) and exercised 90 minutes after a meal (FED) to test the temporal sensitivity of the loaded bone to absorbed nutrients. Participants will also attend a breakfast-only arm (without the exercise protocol).

Participants will undergo a baseline assessment for health history (PAR-Q). The blood samples will be collected (10ml) and osteogenic response to exercise will be determined by measuring markers of bone formation; P1NP and resorption; CTX-1 and cortisol; marker of physiological and psychological stress. Insulin and glucose measurements will allow to assess the change of concentrations in fasted and fed states.
