Functional evaluation of physical exercise performed on vibrating platforms

Evaluación funcional del ejercicio físico realizado en plataformas vibratorias

Introduction

Physical activity (PA) is understood as any voluntary motor action involving energy expenditure caused by skeletal muscles. PA is a necessary component for a healthy lifestyle, however, it is necessary to understand that it is possible to differentiate physical exercise (PE) considered as a type of PA, a process determined by factors of programming, systematization and organization and that influence directly on one or more elements of physical fitness, as well as an indicator of cardiovascular and metabolic risk.

The PE involves organic adaptations that allow the subject to carry out his activities in a more efficient way, in addition to enjoying a state of adequate health by increasing the energy expenditure, both in activity and at rest, causing a change in homeostasis that can be achieved to reflect on the body weight. The balance between energy consumption/expense is achieved in part because skeletal muscles require energy substrates, coming from the catabolism of ingested carbohydrates and lipids, which convert chemical energy into mechanical energy that is then translated into muscle contraction and therefore on the move. On the other hand, aerobic PE performed at intensities ranging from 55 to 70% of the maximum oxygen consumption (VO₂max), promotes the oxidation of fat acids that are mobilized from the adipose tissue (Achten, Gleeson & Jeukendrup, 2002), therefore, causes a decrease in the grease mass.

That is why moderate intensity aerobic activities have been the most used to control body weight; however, exercise performed with resistance or strength also tends to decrease the lipid profile at the blood level (Caamaño-Navarrete, Barría & Floody, 2015), with which a loss of body fat of up to 10% is generated in people with obesity when overload programs are applied, carried out with a frequency of 2 to 3 days per week and with loads greater than 40% of 1RM (Balsalobre-Fernández & Tejero-González, 2015). So, when aerobic exercise and strength exercise are combined, a significant gain in cardiorespiratory capacity and muscle mass is observed, while visceral fat tends to decrease (Simon, Sánchez, Suarez & González, 2021).

Activities such as walking, jogging or cycling, carried out with a frequency of up to five days a week, generate changes in weight, body fat, serum concentrations of triglycerides, total cholesterol, HDL, LDL, glucose, loss of visceral and hepatic fat (Washburn, et al. 2015, Shlisky, et al., 2015, Ross, et al., 2015).

The options for exercising are wide and varied, however, several studies affirm that the most effective methods to cause changes at the body level are those that combine aerobic exercise and muscular strength with nutritional follow-up, however, it becomes necessary to explore other ways. Of PE so that the population can choose the most appropriate to their needs and tastes. For example, the use of machines that use mechanical vibrations that are transmitted throughout the body cause stimuli that manage to increase the gravitational load on the neuromuscular system (Tous & Moras, 2004). Likewise, improvements have been reported in vertical jump performance derived from the increase in strength in the outer muscles of the knee (Manonelles, Giménez, Álvarez & García, 2007), increase in muscular performance of the whole body, balance, isometric strength, grip strength and body balance (Torvinen, et al., 2003).

There are still many doubts about the effects of vibrating platforms for body weight control and if we add to this, the interest in staying active in the confinement conditions that have been imposed since the beginning of 2020, the Covid-19 pandemic, We decided to carry out this intervention, whose general objective was to evaluate oxygen consumption (VO₂ m), using mechanical vibration platforms in healthy individuals, to verify their caloric expenditure compared to other forms of PE and determine its impact on overweight control.

Method

A quasi-experimental study design was carried out, in which we worked with 42 healthy men with an age of 20.28 ± 2.9 years, a height of 171.35 ± 7.01 cm, and a weight of 67.47 ± 8.75 kg.

The participants underwent a medical evaluation to determine their state of health, hereditary-family history, recent pathologies and injuries present at the time of carrying out this study, additionally weight and height were recorded according to the standards set by the Society International for the Advancement of Kinanthropometry, ISAK for its acronym in English (Esparza-Ross, Vaquero-Cristóbal & Marfell-Jones, 2019).

The Modified Bruce (MB) test was applied to assess VO2max. For this, the study subjects were summoned at 07:00 h. fasting and without having performed physical activity the day before. The evaluation protocol was carried out with a Technogym D9.3 treadmill and a Cosmed gas analyzer, Quark CPET model, which was calibrated prior to use.

On different days and under the same fasting conditions and hours, the evaluation of oxygen consumption (VO₂) was performed on a Bioshaker® brand Compact® model vibrating platform. Each subject remained for 15 min in a static position with legs slightly bent and arms in a cross position on the chest at a vibration of 2,500 cycles per minute, recording VO₂ at 5, 10 and 15 min of the test.

Statistical analysis

Central tendency measures were applied to describe the study population. The Kolmogorov Smirnov test was performed to identify the normality of the data (p> 0.05), derived from this, the T test for related samples was applied to identify the differences between the two evaluation protocols. The SPSS v 21.0 program was used for data analysis.

Results

The average maximum oxygen consumption of the participants was 3.01 ± 0.4 L/min while the oxygen consumption obtained while performing the protocol on the vibrating platform was 1.03 ± 0.33. Table 1

As already mentioned above, the VO₂ max. represents the physiological threshold reached by each participant and therefore it was considered as 100% of the capacity to capture, transport and use oxygen in each individual (Del Río, Velasco & Pérez, 2014), in such a way that when they were compared the results of oxygen consumption (VO₂), obtained on the vibrating platform with VO2max, it was found that the use of the platform reaches 34.2% of the maximum possible, and that it represents an effort that does not require the mobilization of acids fat stored in adipose tissue.

Through the T-Student statistic, the VO₂max yielded by the Bruce test was compared with the VO2 obtained with the vibrating platform (Bioshaker®), taking into account a 95% confidence level (α = 0.05). Resulting in a highly significant p-value of 0.000. Therefore, there are sufficient statistical tests to consider the relationship between the variables, which implies that oxygen consumption (VO₂) is related to the tests performed (Bruce or Bioshaker®). Figure 1.

Discussion

The aim of this intervention was to assess oxygen consumption using a mechanical vibration platform in healthy individuals.

The VO₂max. represents the physiological threshold reached by each participant and therefore it is considered as 100% of their capacity to capture, transport and use oxygen and therefore it is a global estimate of physical fitness (Del Rio, Velasco & Pérez, 2014), in such a way that when the results of oxygen consumption (VO₂) obtained on the vibrating platform are compared with VO₂max. It was identified that the study subjects reached 38.2% of the maximum possible on the mechanical vibration platform.

To determine the intensity with which a physical exercise is performed, different methods are used, Londeree & Ames (1976) as well as Pollock, Wilmore & Fox (1990), who calculated the intensity of the exercise based on the theoretical maximum heart rate and what related the percentage of VO₂max.

The use of a vibrating platform in the manner suggested by the manufacturer (15-min sessions) is equivalent to performing a mild intensity physical exercise (such as walking on a horizontal surface), which does not generate a significant impact on the mobilization of adipose tissue in order to catabolize fatty acids to produce energy and therefore influence the loss of body mass. Table 2.

Regarding caloric expenditure, the measurement of maximum oxygen consumption with stress tests, as was the case with the modified Bruce test, is considered one of the indirect calorimetry assessment protocols mostly used by experts. With these indirect calorimetry tests, it has been determined that one liter of oxygen consumed per minute allows the body to metabolize the necessary substrates to produce 5 kcal per minute. The study subjects consumed 5.15 kcal per min. Therefore, if the platform is used in periods of 15 minutes a day (according to the manufacturer's instructions), the caloric expenditure it produces is 77.25 kcal. equivalent to performing low-intensity physical activities (Mataix, 2015). Table 3.

To carry out the physical activities of daily life, the contribution that cardiorespiratory capacity can give to the execution of these tasks adequately is important. In addition to the benefits that it can generate in health, derived from weight control, which consequently reduces the risk of suffering from diseases such as diabetes, hypertension, osteoporosis, among others. About, Méndez, et al., (2021) report that after carrying out a relationship between indicators of muscle strength and oxygen consumption, it was possible to verify that the VO₂ max. is positively associated with muscular endurance, while Becerra, Reigal, Hernández-Mendo & Martín-Tamayo (2013) explain the relationship between physical condition, body composition and self-perception of health in adolescents, demonstrating that VO₂ max negatively predicts the factors, somatic symptoms, anxiety and insomnia.

Regarding the energy expenditure generated by the use of vibrating platforms, it was possible to verify that these machines generate a limited energy expenditure to create significant changes in body weight and consumption of fatty acids to produce energy. The World Health Organization (2012) recommends that physical activity for the age group from 18 to 64 years should be moderate for at least 150 to 300 minutes or vigorous activities for 75 to 150 minutes.

However, the use of vibrating platforms generates a stimulus that supposes for the muscles an increase in the gravitational load that they must support to generate adaptations of different kinds, since results are reported where gymnasts have increased their strength from five to six times more than traditional training (de Hoyo, Páez, Corrales & Da Silva-Grigoletto, 2011), improves static and dynamic balance (Usano, Abián & Abián-Vicen, 2014), modifies the mechanical characteristics of the jump and muscular behavior improving the speed of shortening of the muscle fiber (Rubio, Martínez, Mendizábal, Ramos & Jiménez, 2012). The use of vibrating platforms is promoted as an alternative for carrying out physical activity, even as an effective method for weight control, therefore, and derived from the results obtained and the discussion carried out, it was concluded that the use of vibration platforms Vibration exercises are not an adequate option to develop cardiorespiratory capacity and therefore an increase in VO₂ max. Consequently, it is limited to generate changes at the level of body mass, so it is not a viable option for weight control.
