Metabolic Cost of Bodyweight Training

University of Thessaly10 enrolled

Overview

In this study, the investigators will be able to estimate the metabolic cost of several foundational bodyweight training exercises.

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 exercise-induced energy expenditure

Exercise energy expenditure (kcal) will be measured using a portable indirect calorimetry system

Time frame: At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)

Change in excess post-exercise oxygen consumption (EPOC)

EPOC (kcal) will be measured using a portable indirect calorimetry system

Time frame: At post-exercise session (single bout lasting 30 and 45 seconds)

Change in blood lactate concentration (BLa)

BLa (mmol/L) concentration will be measured in a microphotometer with commercially available kits.

Time frame: At pre- and post-exercise session (single bout) at 3 minutes post-exercise

Change in heart rate

Heart rate (bpm) will be measured with a wearable heart rate monitor

Time frame: At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)

Change in perceived exertion

Rating of perceived exertion (RPE) will be measured with the Borg scale (0-10)

Time frame: At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)

Secondary Outcomes

Body weight

Body weight will be measured on a beam balance with stadiometer

Time frame: At baseline

Body height

Body height will be measured on a beam balance with stadiometer

Time frame: At baseline
