Overview
Brief Summary
In this study, the investigators will be able to estimate the metabolic cost of several foundational bodyweight training exercises.
Detailed Description
Bodyweight training has become a popular cardiovascular training choice in fitness centers and athletic performance enhancement facilities. Despite widespread use and growing popularity, little is known about the metabolic demands of such a training method. Therefore, the purpose of this study was to quantify the cardiovascular and metabolic cost from various foundational bodyweight exercises in order to contribute to a better planning of exercise programs in the real world. Ten healthy young adults were assigned to execute seven bodyweight exercises (acute bout) for 30 and 45 seconds. Anthropometric, metabolic, and performance measurements were conducted at baseline. The metabolic cost was estimated from heart rate, blood lactate, resting oxygen uptake, exercise oxygen uptake, and excess post-exercise oxygen consumption measurements using a portable gas analyzer.

Outcomes
Primary Outcomes
Change in perceived exertion
Time Frame: At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)
Rating of perceived exertion (RPE) will be measured with the Borg scale (0-10)
Change in blood lactate concentration (BLa)
Time Frame: At pre- and post-exercise session (single bout) at 3 minutes post-exercise
BLa (mmol/L) concentration will be measured in a microphotometer with commercially available kits.
Change in exercise-induced energy expenditure
Time Frame: At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)
Exercise energy expenditure (kcal) will be measured using a portable indirect calorimetry system
Change in heart rate
Time Frame: At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)
Heart rate (bpm) will be measured with a wearable heart rate monitor
Change in excess post-exercise oxygen consumption (EPOC)
Time Frame: At post-exercise session (single bout lasting 30 and 45 seconds)
EPOC (kcal) will be measured using a portable indirect calorimetry system
