Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The investigational product is an ARTG listed (Aust L 187766) commercially available capsule-form herbal medicine containing Trigonella foenum- graecum (Fenugreek) seed extract.

The daily dose will be 1 capsule taken in the morning and evening (total 2 capsules per day) of either 300mg or 600mg for a period of 8 weeks. The allocation is randomised.

All participants are provided with a bottle of the product (active or placebo) and be asked to complete 3 set training sessions weekly.

The following blood tests will be performed at baseline and week 8 to assess the effect of the product and for safety measures, liver function, Bilirubin, full blood count, creatinine/eGFR, Homocysteine, glutathione, malonyldialdehyde, reactive oxygen species, c-reactive protein, blood glucose and tolerance, cortisol and testosterone.

Adherence to the intervention will be monitored by drug tablet return.

Exercise Schedule
Each exercise session will run for approximately 15mins and involves:
1. a warm-up/light stretch and mobility phase (approx 5 mins)
2. targeted resistance phase (changing on a weekly basis) (approx 10-15mins)
3. cool down and mobility stretch (approx 5 mins); and
4. recovery phase (in own time)

Participants undertaken 3 exercise training sessions weekly. Except weeks week 4 and week 8 when a strength and exercise performance assessment will be undertaken and only two exercise sessions.

In the first week there will be a strong emphasis on technique and not doing any more or less than what is given. Furthermore, a clear understanding of any previous injuries or restrictions anyone might have. As this week goes on, exercises will become more intense and depending each participants ability, the exercise will be modified to become more challenging.

Types of exercise range from core (eg sit-ups), weights (eg one arm rows, kettle bell swings), body strength (eg lunges, push ups).

Participation at each training session will be signed off.

The exercise sessions are led by a qualified personal trainer and overseen by a Exercise Physiologist

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential participants are screened by the investigator for inclusion in the study. The eligible participants are enrolled by investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the number. The investigator is blinded to the product randomized with the
numbered containers labelled prior to delivery to investigational site. Product allocated as participants are enrolled in sequential order (1-120).
