Brief Summary

Strength training is effective for promoting longevity. The iso-inertial training method is an innovative way to improve strength, but it is unclear whether it improves muscle power and functional variables that are key to develop activities of daily living. The purpose of this study is to conduct a randomised controlled trial at the gymnasium Espai Esport Wellness Center (Granollers) involving physically active older adults (age ≥60). Our goal is to evaluate the effectiveness of a 6-week iso-inertial strength program on the muscle power, physical fitness and risk of falls compared to executing that program with a traditional gravitational strength method. Providing older adults with new, effective methods to preserve their functional capacities is essential for longevity. Also, bringing them into an active environment could encourage a healthier lifestyle and reduce the risk of physical and mental diseases.

Outcome Measures

Primary Outcomes (1)

• Muscle power during the eccentric

  Muscle power during the eccentric phase measured with both iso-inertial and gravitational devices, measured with a rotatory and a linear encoder (Chronojump Boscosystem®), respectively.

  Before the first training session and one week after the last training session

Secondary Outcomes (5)

• Muscle power during the concentric

  Before the first training session and one week after the last training session

• Balance

  Before the first training session and one week after the last training session

• Risk of falls

  Before the first training session and one week after the last training session

• Walking speed

  Before the first training session and one week after the last training session

• Lower limb functionality

  Before the first training session and one week after the last training session

Study Arms (2)

Gravitational group

ACTIVE COMPARATOR

Participants will have to perform a 6-week programme based on three exercises: front lunge, side lunge, and front lunge with hand grip pull, that will be the basis of each session. Exercices will be performed with the gravitational device.

Other: Gravitational training

Isoinertial group

EXPERIMENTAL

Participants will have to perform a 6-week programme based on three exercises: front lunge, side lunge, and front lunge with hand grip pull, that will be the basis of each session. Exercices will be performed with the isoinertial device.

Other: Isoinertial training

Interventions

Isoinertial training OTHER

For the front lunge and the front lunge with hand grip pull, the participant will be placed frontally on the training device (inertial). Whereas for the side lunge the participant will be placed sideways on the device (homolateral on the scrolling limb). For front and side lunge, a weight shift belt will be used, which will be placed on the waist. For the frontal lunge with hand grip pull, the grip is performed with the upper limb homolateral to the displaced lower limb. The volume and difficulty of execution of the exercises will increase over time. Investigators will instruct the participants to perform the exercises at a given intensity according to the Borg Rating of Perceived Exertion (RPE) scale. The intensity will increase throughout the training program.
