Sarcopenia, Active Aging and Oral Microbiota. Effects of HIIT in Older Adults

It will be carried out after a 10-minute warm-up period with joint mobility exercises and dynamic stretching. The intervention will consist of a training in which intense work intervals and active rest periods are combined using a cycle ergometer. The session will be divided into 4 intervals of 4 minutes duration at an intensity of 85-95% of the maximum heart rate \[MHR\], individually controlled during all sessions (Polar Team pro®), followed by active rest intervals of 3 minutes duration at 50-70% FCM. After training, a 10-minute cool-down of gentle pedaling and joint range exercises will be carried out.

Heating phase identical to the previous one. Subsequently, the participants will perform training on the cycle ergometer with an intensity close to 70% FCM maintained for 40 minutes and will be individually controlled (Polar Team pro®). The session will conclude with a cool-down phase identical to the previous one.
