Brief summary: Background: Pilates is a form of structured physical activity that is commonly used in rehabilitation settings and to improve muscular fitness, balance, and flexibility. Despite its popularity, it is not known whether the energy expenditure (EE) and oxygen consumption from Pilates sessions could also lead to metabolic fitness benefits. The aim of this study was to quantify the intensity and the EE during two different types of Pilates sessions (mat and apparatus). Methods: 18 healthy females (age: 22 ± 3 years; height: 1.6 ± 0.1cm; body mass: 61.0 ± 10.0 kg; body mass index: 21 ± 3 kg/cm2) performed two different sessions. Each session involved the performance of 15 different exercises. Oxygen consumption (VO2) was measured continuously and then converted to EE in Kcal/min. Blood lactate, heart rate (HR), and blood pressure (BP) were also measured. A repeated measures two-way ANOVA (time X group) determined differences between types.

Detailed description: The participants attended two half-hour Pilates exercise classes twice a week, for one month, to familiarize themselves with the exercises and to learn the 5 Pilates' principles. After the learning period, two experimental sessions were performed: a Mat Pilates session and a Reformer apparatus Pilates session. The order of each session was randomized and drawn beforehand. Each experimental session lasted about one and a half hours and the interval between the sessions was 48 hours. Participants were asked to not perform any exercise and to refrain from food or fluids except water eight hours prior to each experimental session. Prior to the start of the experimental sessions, participants received a standard breakfast of 321 kcal that was 76% (61 g) carbohydrate, 8% (6,7 g) protein, 16% (5,9) fat, provided by the study researchers. All sessions were conducted at the same time in the morning, and the room temperature (22°C) and humidity (40-50%) were controlled during the whole session.

Prior to the start of experimental sessions, participants rested in a supine position for 15 minutes. At the end of the 15 minutes, while still supine, measurements of BP and resting blood lactate were taken using standard laboratory procedures. Participants were then outfitted with a oxygen gas analyzer (Metalyzer 3b Cortex, Germany). Participants were connected by a mask, covering mouth and nose, to a digital gas flow analyzer. Standard calibration before every session was conducted according to the manufacturer's instructions.VO2 and HR were then simultaneously recorded for 5 minutes in a sitting position. At the end of the 5 minutes, the exercise session was started. VO2 and HR were monitored continuously throughout the session, while BP was assessed during rest intervals between exercises. At the end of the exercise session, BP and blood lactate were measured one time in a supine position in the post recovery time period. VO2 and HR were measured continuously for 5 minutes post session in a sitting position.
