Both dieting and physical activity play a critical role in maintaining healthy body weight, or maintaining successful weight loss. [10] Physical activity helps control weight by using excess calories that would otherwise be stored as fat. Most activities burn calories, including sleeping, breathing, and digesting food. Balancing the calories ...
The effect of training on the body has been defined as the reaction to the adaptive responses of the body arising from exercise [3] or as "an elevation of metabolism produced by exercise". [4] Exercise physiologists study the effect of exercise on pathology, and the mechanisms by which exercise can reduce or reverse disease progression.
The energy for ATP resynthesis comes from three different series of chemical reactions that take place within the body. Two of the three depend upon the food eaten, whereas the other depends upon a chemical compound called phosphocreatine. The energy released from any of these three series of reactions is utilized in reactions that resynthesize ...
Aerobic exercise, also known as cardio, is physical exercise [1] of low to high intensity that depends primarily on the aerobic energy-generating process. [2] " Aerobic" is defined as "relating to, involving, or requiring oxygen", [ 3 ] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [ 4 ]
Post-exercise nutrition is an important factor in a nutrition plan for athletes as it pertains to the recovery of the body. Traditionally, sports drinks such as Gatorade and Powerade, are consumed during and after exercise because they effectively rehydrate the body by refueling the body with carbohydrates, [ 25 ] minerals and electrolytes.
We also want to note that weight loss, health, and body image are complex subjects—before starting a diet, we invite you to gain a broader perspective with our exploration of rethinking body weight.
It is especially important for older adults to maintain physical activity and cardiorespiratory fitness while minimizing the risk of injury. A workout plan for older adults may include activities ...
Set point theory can be construed as implying weight regulation in a wide or tight range around the set point, in a symmetric or in an asymmetric manner (i.e. treating weight gain and loss either the same or differently), and may apply to regulation of body fat levels specifically (in a multi-compartment model) or to overall body weight.
