Purpose:

This study examined the effects of a five-week intervention combining vigorous interval training (VIT) with diet among twenty-four obese adolescents. Fourteen girls and ten boys (aged 14–15) schooled in a pediatric rehabilitation center participated.

Methods:

The VIT intensity was targeted and remained above 80% of maximal heart rate (HR) and over six kilocalories per minute. Pre- and postintervention measures were body composition (BMI, weight, body fat percentage), physical self-perceptions (PSP), physical fitness (6-min walking distance and work) and its associated physiological responses (HRpeak and blood lactate concentration). A series of two-way analyses of variance or covariance controlling for weight loss were used to examine the changes.

Results:

Significant improvements were found in body composition, physical fitness and PSP (endurance, activity level, sport competence, global physical self-concept and appearance). In addition, boys presented higher levels of perceived strength and global physical self-concept than girls. Finally, there was a significant increase in perceived endurance, sport competence, and global physical self-concept in girls only.

Conclusion:

This five-week VIT program combined with diet represents an effective means for improving body composition, physical fitness, and PSP in obese adolescents, the effects on PSP being larger among girls.

High-intensity interval training (HIIT) is regarded as a highly effective training modality to improve cardiorespiratory and metabolic functioning, and it is a common practice in training regimens of many athletes, particularly those involved in endurance events. 1 In HIIT, repeated periods of

youth in physical activity of sufficient volume and intensity to maintain and improve CRF. High-intensity interval training (HIIT) has emerged as a relatively novel and time-efficient strategy for improving CRF in adolescents. HIIT involves short bursts of high-intensity activity (ie, ≥85% heart rate

-controlled, counterbalanced design was used to determine if EECP could enhance recovery after a high-intensity interval training (HIIT) session, where each subject acted as his or her own control. Subjects were informed that they were participating in a study comparing the effects of 2 different EECP protocols: one that

High-intensity interval training (HIIT) is a structured exercise format that has recently attracted significant research attention in a wide range of populations ( Sultana, Sabag, Keating, & Johnson, 2019 ). The most recent U.S. Physical Activity Guidelines Committee scientific report refers to

High-intensity interval training (HIIT) involves repeated bouts of high-intensity exercise interspersed with recovery periods. This method is typically employed to increase the training stimulus for the cardiorespiratory system over prolonged continuous exercise. Accordingly, much of the scientific

With this in mind, high-intensity interval training (HIIT) was developed with low-volume exercises. Furthermore

High-intensity interval training (HIIT) is an exercise regimen that seems to be gaining more popularity in the general population as a quick and effective, yet enjoyable, way to partake in physical activity. High-intensity interval training, just like MICT, can take place in many different forms
