Grupo de participantes/brazo |
Intervención / Tratamiento |
---|---|
Experimental: Exercise Only Group (EX)
Participants will only receive the exercise protocol without nutrition education or counseling and instructed to continue to consume their regular diet.
|
The exercise protocol consists of a nine-week progressive intense-conditioning program involving six consecutive days (Monday-Saturday) of one-hour exercises and one-day rest weekly for a total of 54 days of exercise.
Exercises are performed in person as a group with other participating subjects and lead by certified instructors.
Exercises will involve a variety of activities ranging from running, cycling, whole-body functional movements, power movements, and open-chain weight lifting with barbells and resistance bands.
|
Experimental: Exercise with CR-LC Group
Participants will receive the exercise protocol and CR-LC Diet regimen.
|
The exercise protocol consists of a nine-week progressive intense-conditioning program involving six consecutive days (Monday-Saturday) of one-hour exercises and one-day rest weekly for a total of 54 days of exercise.
Exercises are performed in person as a group with other participating subjects and lead by certified instructors.
Exercises will involve a variety of activities ranging from running, cycling, whole-body functional movements, power movements, and open-chain weight lifting with barbells and resistance bands.
Consists of weekly nutrition plans, counseling and monitoring by on-site registered dietitians and nutritionists for nine weeks.
CR-LC consists of caloric and macronutrient restrictions.
Caloric restrictions involves a 40% deficit from calculated total daily energy expenditure.
Macronutrient restriction involves a high protein, low carbohydrate diet (35% protein, 25% carbohydrate and 40% fat).
|
Experimental: Exercise with Ancestral Diet (AD) Group
Participants will receive the exercise protocol and AD regimen.
|
The exercise protocol consists of a nine-week progressive intense-conditioning program involving six consecutive days (Monday-Saturday) of one-hour exercises and one-day rest weekly for a total of 54 days of exercise.
Exercises are performed in person as a group with other participating subjects and lead by certified instructors.
Exercises will involve a variety of activities ranging from running, cycling, whole-body functional movements, power movements, and open-chain weight lifting with barbells and resistance bands.
Consists of weekly nutrition plans, counseling and monitoring by on-site registered dietitians and nutritionists for nine weeks.
AD consists of consuming only whole foods and avoiding processed foods.
Emphasis will be on food quality with no caloric or macronutrient restrictions.
