Brief Summary

This study investigates the physiological responses and the metabolic burden of a Pilates Reformer strength training session in physically inactive premenopausal women with a body mass index of 18-24.9 and 25.01-39.9. The sample included 20 women divided into two groups: 10 with normal weight (NW) and 10 with overweight/obesity (OB). In a non-randomised control design, the participants will perform a 60-minute muscle-strengthening session with Pilates Reformer equipment.

Outcome Measures

Primary Outcomes (8)

• Change in exercise-induced energy expenditure

  Exercise energy expenditure (kcal) will be measured using a portable indirect calorimetry system

  At pre-exercise, 60 minutes during PR training, and 30 minutes after the exercise session (single bout lasting 60 minutes)

• Change in excess post-exercise oxygen consumption (EPOC)

  EPOC (kcal) will be measured using a portable indirect calorimetry system

  At 30 minutes after the exercise session (single bout lasting 60 minutes)

• Change in blood lactate concentration (BLa)

  BLa (mmol/L) concentration will be measured in a microphotometer with commercially available kits

  At pre- and post-exercise session (single bout) at 4 minutes post-exercise

• Change in heart rate

  Heart rate (bpm) will be measured with a wearable heart rate monitor

  At pre-exercise, 60 minutes during PR training, and 30 minutes after the exercise session (single bout lasting 60 minutes)

• Change in perceived exertion

  Rating of perceived exertion (RPE) will be measured with the Borg scale (0-10)

  At pre- and post-exercise session (single bout) at 4 minutes post-exercise.

• Respiratory Exchange Ratio (RER)

  Respiratory Exchange Ratio (RER) will be measured using a portable indirect calorimetry system

  At pre-exercise, 60 minutes during PR training, and 30 minutes after the exercise session (single bout lasting 60 minutes)

• Breath Frequency (BF)

  Breath Frequency (BF) will be measured using a portable indirect calorimetry system

  At pre-exercise, 60 minutes during PR training, and 30 minutes after the exercise session (single bout lasting 60 minutes)

• Change in oxygen consumption

  Oxygen consumption will be measured using a portable indirect calorimetry system

  At pre-exercise, 60 minutes during PR training, and 30 minutes after the exercise session (single bout lasting 60 minutes)

Secondary Outcomes (18)

• Body weight

  At baseline and at 40 minutes after the exercise session.

• Body height

  At baseline

• Body mass index (BMI)

  At baseline

• Waist circumference (WC)

  At baseline

• Hip circumference (HC)

  At baseline

Study Arms (2)

Pilates Reformer Training (OW)

EXPERIMENTAL

A group of women with overweight/obesity in this arm will participate in a 60-minute muscle-strengthening training session with Pilates Reformer equipment.

Other: Pilates Reformer Training

Pilates Reformer Training (NW)

EXPERIMENTAL

A group of women with normal weight in this arm will participate in a 60-minute muscle-strengthening training session with Pilates Reformer equipment.

Other: Pilates Reformer Training

Interventions

Pilates Reformer Training OTHER

Participants will perform a 60-minute Pilates Reformer muscle-strengthening session. The training will include a 7-10 minute warm-up, 35 minutes of muscle strengthening and mobility exercises and a 5-minute recovery. During the training, the physiological responses and the energy expenditure of the participants will be recorded.
