Background:
Previous studies have reported no improvements in quality of life or physical function following exercise training in patients with multiple myeloma, without a clear explanation. The purpose of the present study was to examine the effects of an exercise-training intervention on these outcomes and to determine whether the observed results could be explained by the characteristics of the training program.
Methods:
Sixteen patients with multiple myeloma who had completed first-line induction therapy were assigned to two groups. One group (2 men, 6 women, 52.6 ± 10.3 years) commenced maintenance therapy only, while the other group (2 men, 6 women, 58.8 ± 7.1 years) initiated maintenance therapy combined with a supervised exercise training program conducted twice per week. Each exercise session included 30 min of cycling and seven resistance exercises targeting the major muscle groups. The intervention lasted 4.4 ± 1 months. QoL, the six-minute walking test, handgrip strength, maximal aerobic power, maximum isometric contraction across 14 positions, and bone density were assessed before and after the intervention.
Results:
The six-minute walking test distance significantly increased in the exercise group (9.36 ± 6.88%, p = 0.001), while no change was observed in the control group (3.34 ± 5.68%, p = 0.162); however, the difference between groups was not statistically significant (p = 0.076). QoL and maximal aerobic power remained unchanged in both groups, while maximal isometric strength increased significantly in both groups.
Conclusions:
The progression of the training stimulus appears to be inconsistent in this specific population, potentially limiting improvements in quality of life and physical function outcomes. Supervision appears to be necessary for exercise training in patients with multiple myeloma. Future research should investigate alternative exercise modalities in these patients.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
