VO 2 max, or milliliters of oxygen per kilogram of body mass per minute (e.g., mL/(kg·min)), is considered an excellent proxy for aerobic fitness. [8] Consequently, attempts have been made to correlate Yo-Yo test scores with VO 2 max. There are conflicting reports about such a correlation. Two studies [9] [10] reported only a weak correlation.
These two values have been reported as important factors in sports with quick, all-out efforts. Short sprinting events rely heavily upon the anaerobic energy pathways during execution, [2] which leads to speculation that greater performance in a Wingate test can predict success in these events. This has not been proven, and the more applicable ...
The available oxygen and energy supply, and disturbances of muscle ion homeostasis are the main factors determining exercise performance, at least during brief very intense exercise. Each muscle contraction involves an action potential that activates voltage sensors, and so releases Ca 2+ ions from the muscle fibre 's sarcoplasmic reticulum .
Social influences on fitness behavior are the effect that social influences have on whether people start and maintain physical activities. Physical fitness is maintained by a range of physical activities. Physical activity is defined by the World Health Organization as "any bodily movement produced by skeletal muscles that requires energy ...
Specifically, the Presidential Youth Fitness Program has focused their energy on shifting ideas away from the measurements of athletic performance and turning toward health-related fitness. [19] The Fitness Test was designed to capture best performance at core strength, aerobic capacity, upper-body strength, speed and agility, and flexibility. [14]
Movement assessment is the practice of analysing movement performance during functional tasks to determine the kinematics of individual joints and their effect on the kinetic chain. Three-dimensional or two-dimensional analysis of the biomechanics involved in sporting tasks can assist in prevention of injury and enhancing athletic performance.
In sports medicine, a preparticipation physical evaluation (PPE) is a physical examination of an athlete. [1] PPEs screen for a variety of conditions, including athletic heart syndrome [ 2 ] and risk of sudden cardiac death .
The amount of physical activity conducted by a population—and by extension the proportion of that population reaching guidelines or other specified thresholds—is dictated by a number of factors including demographics (e.g., age, sex, ethnicity), population health status, cultural aspects, and the state of the environment itself (e.g ...
