Brief Summary

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

Detailed Description

Battle rope 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 battle rope 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, functional capacity 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.

Arm && Interventions

Group	Intervention	Description
Training	BR-30	Participants in this arm will perform five battle rope training exercises (acute bout per exercise) at two different conditions (30 and 45 seconds).
Training	BR-45	Participants in this arm will perform five battle rope training exercises (acute bout per exercise) at two different conditions (30 and 45 seconds).

Primary Outcome Measures

Name	Time	Method
Change in excess post-exercise oxygen consumption (EPOC)	At 1 hour after exercise session (single bout lasting 30 and 45 seconds)	EPOC (kcal) will be measured using a portable indirect calorimetry system
Change in exercise-induced energy expenditure	At pre-exercise, during and 30 minutes after 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	At pre-exercise, during, and 30 minutes after exercise session (single bout lasting 30 and 45 seconds	Heart rate (bpm) will be measured with a wearable heart rate monitor
Change in blood lactate concentration (BLa)	At pre exercise and at 3 minutes after exercise session	BLa (mmol/L) concentration will be measured in a microphotometer with commercially available kits.
Change in perceived exertion	At pre-exercise, during, and 30 minutes after exercise session (single bout lasting 30 and 45 seconds	Rating of perceived exertion (RPE) will be measured with the Borg scale (0-10)

Secondary Outcome Measures

Name	Time	Method
Body weight	At baseline	Body weight will be measured on a beam balance with stadiometer
Body mass index (BMI)	At baseline	BMI will be calculated using the Quetelet's equation
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
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)
Maximal strength (1RM)	At baseline	1RM (kg) will be measured bilaterally on a horizontal leg press and seated chest press machine.
Body height	At baseline	Body height will be measured on a beam balance with stadiometer
Waist circumference (WC)	At baseline	WC (cm) will be measured using a Gullick II tape
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)
Functional capacity	At baseline	Functional capacity will be assessed using a movement-based screening tool titled Functional Movement Screening (FMS). The FMS will be consisted of 7 movement tasks that will be scored from 0 to 3 points and the sum will create score ranging from 0 to 21 points (0 = pain with pattern regardless of quality, 1 = unable to perform pattern, 2 = able to perform pattern with compensation/imperfection, 3 = able to perform pattern as directed)
Resting metabolic rate (RMR)	At baseline	RMR (kcal) will be measured using a portable open-circuit indirect calorimeter with a ventilated hood system
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
Muscular endurance	At baseline	Muscular endurance (repetitions) will be measured on a 1-min curl-up and push-up test.
