Background and objectives
Active music-making in combination with physical exercise has evoked several positive effects in users of different age groups. These include enhanced mood, muscular effectivity, pain threshold, and decreased perceived exertion. The present study tested the applicability of this musical feedback system, called
Jymmin
®
, in combination with strength-endurance exercises in a population of healthy older adults.
Research design and methods
Sixteen healthy, physically inactive older adults (5 males, 11 females) at the mean age of 70 years performed physical exercise in two conditions: A conventional work-out while listening passively music and a
Jymmin
®
work-out, where musical sounds were created with one's work-out movements. According to the hypothesis that strength-endurance is increased during musical feedback exercise, parameters relating to strength-endurance were assessed, including
exercise duration, number of repetitions, perceived exertion
(RPE), and
participants' mental state
(Multidimensional Mood State Questionnaire; MDMQ).
Results
Results show that participants exercised significantly longer while doing
Jymmin
®
(
Mdn
= 248.75 s) as compared to the
conventional work-out
(
Mdn
= 182.73 s), (Z = 3.408,
p
= 0.001). The RPE did not differ between
conventional work-out
and the
Jymmin
®
condition, even though participants worked out significantly longer during the
Jymmin
®
condition (Mdn = 14.50; Z = −0.905;
p
= 0.366). The results of the MDMQ showed no significant differences between both conditions (Z = −1.037;
p
= 0.300).
Discussion and implications
Results show that participants could work out longer while showing the same perceived exertion, relating to increased physical endurance. Music feedback work-out encouraged a greater degree of isometric contractions (muscle actively held at fixed length) and, therefore, less repetitions in this condition. In addition to the previously described effect on muscle effectivity, this non-stereotypic contraction pattern during music feedback training may have enhanced endurance in participants supporting them to better proportion energetic reserves during training (pacing).
