The effect of 8 weeks of functional training and chromium picolinate supplementation on leptin levels and body composition of overweight and obese women

Determining the effect of 8 weeks of functional training on blood leptin levels in overweight and obese women Determining the effect of 8 weeks of functional training on body composition (percentage of fat, fat mass and lean mass) overweight and obese women Determining the effect of 8 weeks of chromium picolinate supplementation on blood leptin levels in overweight and obese women Determining the effect of 8 weeks of chromium picolinate supplementation on body composition (fat percentage, fat mass and lean mass) of overweight and obese women

Quasi-experimental study with control group, with cross design, without blinding, random blocking method with 4 blocks and using random number table of random sequence software.

The distal training protocol is performed under the supervision of an instructor and in a gym and will include six types of hopping that will be performed for eight weeks and three 31-minute sessions each week. The intensity of the exercises is applied progressively by adding movements every week.

Admission requirements: Women 25 to 35 years old with a body mass index of 25 and above. Conditions of non-entry: Women who have had a regular exercise program in the past year, or are allergic to chromium supplements, or by a doctor Sports activities are prohibited or no conscious consent.

Group1: Daily intake of chromium picolinate supplement (two doses of 200 micrograms) for eight weeks Group2: Performing functional exercises for 8 weeks Group3: Performing functional exercises and daily consumption of chromium picolinate supplement (two doses of 200 micrograms) for 8 weeks Fourth group (control): not receiving intervention or treatment to reduce the main consequences

Serum leptin, fat percentage, fat mass, lean mass

40 participants are randomly divided into 4 groups using a table of random numbers. In the present study, the restricted randomization method was used, which will be performed in a block randomization method.The size of four blocks is equal and we will have four groups of 40 blocks (including 10 people participating in each group). Randomization tool also uses software random allocation software (Random allocation software). In addition to simple randomization, these random sequence generation software are able to generate random sequences by block generation method. For concealment, we use concealment allocation, so that the assigned group is not known before the individual is assigned. Using opaque envelopes sealed with random sequences (envelopes opaque, sealed, numbered sequentially), in which each random sequence is recorded on a card. And the cards are placed in the envelopes of the letter, respectively. In order to maintain a random sequence, the envelopes are numbered in the same way on the outer surface. Finally, the lids of the letter envelopes are glued and placed inside a box, respectively. At the beginning of the registration of participants, based on the order of entry of eligible participants into the study, one of the envelopes of the letter is opened in order and the assigned group of the participant is revealed.
