Metabolic Cost of Bodyweight Training (BWT-UTH)

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

Study Overview

• Status: Completed
• Conditions: Body Composition; Physical Fitness; Energy Expenditure; Resting Metabolic Rate
• Intervention / Treatment: Behavioral: TR-30; Behavioral: TR-45

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Training; Participants in this arm will perform seven bodyweight training exercises (acute bout per exercise) at two different conditions (30 and 45 seconds).	Behavioral: TR-30; Bodyweight training exercises will be performed for 30 seconds and the training volume will be consisted of 1 repetition.; Behavioral: TR-45; Bodyweight training exercises will be performed for 45 seconds and the training volume will be consisted of 1 repetition.
NO_INTERVENTION: Control; Participants in this arm will receive no intervention.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in exercise-induced energy expenditure	Exercise energy expenditure (kcal) will be measured using a portable indirect calorimetry system	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	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.	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	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)	At pre-exercise, during, and post-exercise session (single bout lasting 30 and 45 seconds)
