Brief Summary

The primary objective of this proposal is to determine the effects of post-exercise peanut consumption on long-term aerobic and resistance exercise training adaptations in middle-aged men and women. The investigators will determine the impact of peanuts on exercise training-induced improvements in muscle strength, gains in muscle mass, and improvements in cardiorespiratory fitness and metabolic capacity.

Conditions

Muscle Strength; Cardiorespiratory Fitness; Body Composition; Peanut Consumption

Keywords

peanut; muscle health; concurrent training; cardiorespiratory fitness

Outcome Measures

Primary Outcomes (3)

• Total Lean Mass

  Amount of lean mass as determined by dual energy x-ray absorptiometry scan

  From baseline to the end of the training program at 16 weeks.

• Muscle strength

  Isometric grip and knee extension strength, as well as dynamic 1-repitition maximum strength of bench press, leg press, overhead press, knee extension

  From baseline to the end of the training program at 16 weeks.

• Cardiorespiratory fitness

  Maximal oxygen consumption as determined by graded treadmill test

  From baseline to the end of the training program at 16 weeks.
