+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
| Arm | Type | Interventions | Description |
|---|
| Training | Experimental | Behavioral: TR-30; Behavioral: TR-45 | Participants in this arm will perform seven bodyweight training exercises (acute bout per exercise) at two different conditions (30 and 45 seconds). |
| Control | No intervention | | Participants in this arm will receive no intervention. |
- TR-30 (Behavioral): Bodyweight training exercises will be performed for 30 seconds and the training volume will be consisted of 1 repetition.
- TR-45 (Behavioral): Bodyweight training exercises will be performed for 45 seconds and the training volume will be consisted of 1 repetition.
+Outcome measures
Primary outcomes
- Change in exercise-induced energy expenditure [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 excess post-exercise oxygen consumption (EPOC) [At post-exercise session (single bout lasting 30 and 45 seconds)]: EPOC (kcal) will be measured using a portable indirect calorimetry system
- Change in blood lactate concentration (BLa) [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 heart rate [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 perceived exertion [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)
Secondary outcomes
- Body weight [At baseline]: Body weight will be measured on a beam balance with stadiometer
- Body height [At baseline]: Body height will be measured on a beam balance with stadiometer
- Body mass index (BMI) [At baseline]: BMI will be calculated using the Quetelet's equation
- Waist circumference (WC) [At baseline]: WC (cm) will be measured using a Gullick II tape
- Hip circumference (HC) [At baseline]: HC (cm) will be measured using a Gullick II tape
- Waist-to-hip ratio (WHR) [At baseline]: WHR will be calculated by dividing the waist by the hip measurement
- Resting metabolic rate (RMR) [At baseline]: RMR (kcal) will be measured using a portable open-circuit indirect calorimeter with a ventilated hood system
- Body fat (BF) Body fat (%) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA) [At baseline]: BF (%) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA)
- Fat mass (FM)t Body fat (%) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA) [At baseline]: FM (kg) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA)
- Fat-free mass (FFM) [At baseline]: FFM (kg) will be assessed by whole-body dual-energy X-ray absorptiometry (DXA)
- Maximal oxygen consumption (VO2max) [At baseline]: VO2max (mL/kg/min) will be assessed by a portable open-circuit spirometry system.
- Maximal strength (1RM) [At baseline]: 1RM (kg) will be measured bilaterally on a horizontal leg press and seated chest press machine..
- Muscular endurance [At baseline]: Muscular endurance (repetitions) will be measured on a 1-min curl-up and push-up test.
