Sweatz Scientific Research

(Scientific Research) - How much weight can I really lose wearing a Sweatz Vest?

The Sweatz Vest is a genuine weight loss marvel. It is one of the few weight loss products in the world which actually burns more calories when used. It is scientifically proven to burn twice the amount of (up to an extra 800kcal) calories when worn when doing any exercise or activity!  This can help you lose weight twice as fast!!!

We recently had the Sweatz Vests tested at one of the UK's top testing universities and the results were amazing!  The Sweatz Vest is now proven to burn these amounts of calories when worn whilst doing any exercise or activity. We are not aware of any other weight loss product in the world with actual scientific research and evidence that can rival the Sweatz Vest.

How much weight can I lose wearing a Sweatz Vest?

Because you can burn off twice the amount of calories when wearing a Sweatz Vest you can lose weight twice as quick.

.The average person wearing a Sweatz Vest each time you exercise can lose at least an extra 2-3 stone per year.

.For those individuals suffering from Obesity the Sweatz Vest can take years off losing weight

We believe the only real way to burn more calories is to wear a Sweatz Vest.

The effect of wearing a ‘Sweatz Vest’ on energy expenditure during steady state exercises

INTRODUCTION

Over the past two decades levels of obesity in Britain have been continually rising (Troiano et al., 1995; Ogden et al., 2002); with research demonstrating that lack of physical activity is the primary cause of obesity (Riddoch et al., 1991; Partick et al., 2004; Ekelund et al., 2004). The simple concept of weight management is the balance of energy expenditure and energy intake, if a person consumes more energy than they expend they gain weight, or if they expended more energy than they consume they lose weight (Blair, 1993; Doucet and Tremblay, 1997).

Weight loss has been shown to result in numerous health benefits including reduction of blood pressure and risk of hypertension (Stevens et al., 2001), hyperlipidaemia, cardio respiratory diseases, and diabetes (Higgins et al., 1993; Oster et al., 1999; Pasanisi et al., 2001), osteoarthritis symptoms (Felson et al., 1992; Felson and Chaison, 1997).

Weight loss can also be essential in weight categorised sports such as boxing, wrestling and judo (Smith et al., 2000; Ohta et al., 2002).

It has been proposed that increases in body temperature increase energy expenditure (Consolazio et al., 1963; Dolny & Lemon, 1988; Nielson et al., 1990; Febbraio et al., 1994a, 1994b; Koga et al., 1997; Ferguson et al., 2002) but may affect performance during aerobic exercise (Galloway and Maughan, 1997; Yamashita et al., 2005; Wendt et al., 2007). The proposed reason for this increase in energy expenditure is that more energy is required for thermoregulation in order to preserve homeostasis of body temperature (Consolazio et al., 1963; Dolny & Lemon, 1988).

The aim of this investigation was to determine if wearing a ‘Sweatz Vest’ altered energy expenditure during 30 minutes of sub maximal aerobic exercise.

METHOD

Ten healthy male subjects participated (age 21 ± 2 years, height 177.8 ± 8.8cm, weight 76.3 ± 8.8Kg) in this study. All participants provided written informed consent and the investigation was approved by the Institutional Review Board at the University of Salford.

Subjects completed a 30 minute run at a constant pace (6mph), at the same time of day, on two separate sessions, 3-4 days apart apart. Participants wore the same clothing for each test, with the only difference being the inclusion of the ‘Sweatz Vest’ which was randomly assigned to either testing session. The ambient temperature (18+0.5oC) of the laboratory was consistent throughout each trial.

Participants were instructed refrain from exercise prior to testing, to replicate their diet on each day of testing (Karst et al., 1984; Donahoo et al., 2004) and to refrain from caffeine consumption on the day of testing (Essig et al., 1980; Van Soerem and Graham, 1998; Hursel & Westerterp-Plantenga, 2010) as these variables can affect muscle metabolism and energy expenditure.

Prior to exercise, subjects were weighed wearing minimal clothing (underwear) and then were not permitted to drink or urinate, until after the post exercise weighing. Each subject was either then given a ‘Sweatz vest’ to wear for the duration of the exercise with normal clothing over it (SV) or wore normal clothing without a ‘Sweatz vest’ as a control test (CON). Participants were then fitted with a face mask to permit collection of inspired and expired air (Morgan Medical Analysis System MXS (MMAS)).

Baseline oxygen uptake (VO2) and carbon dioxide production (VCO2) were recorded during five minutes of stationary standing on the treadmill, to permit calculation of resting energy expenditure. Following this, participants ran on the treadmill at 6mph for 30 minutes. Breath by breath VO2 and VCO2 was recorded for the duration, with HR being recorded every 5 minutes. Energy expenditure at rest and during exercise was later calculated using Weirs formula (Energy Expenditure = (16.318 x VO2) + (4.602 x VCO2)).

Post exercise subjects stripped down to their underwear and sweat was wiped off using paper towels then they were weighed again to measure weight loss.

STATISTICAL ANALYSIS

Paired samples t-tests were conducted to determine differences in energy expenditure between conditions. Alpha level was set at p<0.05.

RESULTS

The ‘Sweatz Vests’ showed a significantly greater energy expenditure, during 30 minutes of running, compared to the control condition (figure 1).

Figure 1: Comparison of energy expenditure during exercise. Acute weight loss was greater during exercise with the ‘Sweatz Vest’ compared to the control condition.

Discussion:

The results of this investigation indicate that wearing a ‘Sweatz Vest’ while exercising at a moderate intensity can significantly increase energy expenditure, compared to the same amount of exercise without wearing a ‘Sweatz Vest’.

Results demonstrated that wearing a ‘Sweatz Vest’ during 30 minutes of moderate intensity exercise resulted in an average 30% increase in energy expenditure. This increase in energy expenditure (30%) is greater than the increase in energy expenditure associated with caffeine based products (4-5%) commonly used as weight loss aids (Hursel & Westerterp- Plantenga, 2010).

This increase in energy expenditure, associated with wearing the ‘Sweatz Vest’, during exercise will facilitate long term weight loss, if during regular (>3x week) exercise.

Conclusion / Application

Wearing a Sweatz Vest during regular aerobic exercise can maximise energy expenditure during training for weight loss, as it results in an average increase in energy expenditure of ~30%.
