“…Three previous studies have investigated the differences in muscle strength between these two groups (Fong et al, 2013;Gomes et al, 2014;Yee et al, 2014). Meanwhile, another report suggested that cancer survivors do not have lower grip strength than healthy subjects (Gomes et al, 2014 Only muscle strength did not represent fatigue in cancer survivors.

“…The results of this study showed that grip strength and knee extension strength were not significantly different between cancer survivors and healthy subjects. Three previous studies have investigated the differences in muscle strength between these two groups (Fong et al, 2013;Gomes et al, 2014;Yee et al, 2014). Two previous studies showed that cancer survivors have lower shoulder muscle strength (Fong et al, 2013), grip strength, and knee extension strength (Yee et al, 2014) than do healthy subjects.…”

“…Cancer survivors with various cancer diagnoses experience fatigue more often than healthy individuals (Smith et al, 2013). To date, a few reports have investigated the differences in physical function between long-term cancer survivors and healthy subjects (Gomes et al, 2014;Yee et al, 2014). Some cancer survivors experience decreased physical function (Kenzik, Morey, Cohen, Sloane, & Demark-Wahnefried, 2015), and weight loss is common among these individuals.…”

“…Reduced physical strength is not inevitable. To date, a few reports have investigated the differences in physical function between long-term cancer survivors and healthy subjects (Gomes et al, 2014;Yee et al, 2014). However, no reports have examined the differences in the relationships between muscle strength and QOL/fatigue between long-term cancer survivors and healthy subjects.…”

We investigated the difference in relationship between muscle strength and quality of life (QOL)/fatigue in long-term cancer survivors and healthy subjects. Thirty-six cancer survivors and 29 healthy subjects were assessed for body composition and bone status at the calcaneus using the Osteo Sono Assessment Index. Muscle strength was evaluated via handgrip and knee extensor strength. Health-related QOL was assessed using the Medical Outcome Study 36-item Short-Form Health Survey. Fatigue was measured using the brief fatigue inventory. Cancer survivors exhibited lower QOL scores in the physical functioning, physical role function, bodily pain and general health domains (p < .05). Grip and knee extension muscle strength in cancer survivors was positively correlated with the physical function and bodily pain of QOL (p < .05). The usual fatigue subscale score was only significantly higher in cancer survivors than in healthy subjects (p < .05). However, there were no correlations between muscle strength and fatigue in cancer survivors. Our results showed that muscle strength was an important factor for improving QOL in cancer survivors. We believe that the findings of this study will be relevant in the context of planning rehabilitation for cancer survivors.

Exacerbated central fatigue and reduced exercise capacity in early-stage breast cancer patients treated with chemotherapy

et al. 2023

Purpose The present study aimed to characterize the etiology of exercise-induced neuromuscular fatigue and its consequences on the force-duration relationship to provide mechanistic insights into the reduced exercise capacity characterizing early-stage breast cancer patients. Methods Fifteen early-stage breast cancer patients and fifteen healthy women performed 60 maximal voluntary isometric quadriceps contractions (MVCs, 3 s of contraction, 2 s of relaxation). The critical force was determined as the mean force of the last six contractions, while W’ was calculated as the force impulse generated above the critical force. Quadriceps muscle activation during exercise was estimated from vastus lateralis, vastus medialis and rectus femoris EMG. Central and peripheral fatigue were quantified via changes in pre- to postexercise quadriceps voluntary activation (ΔVA) and quadriceps twitch force (ΔQTw) evoked by supramaximal electrical stimulation, respectively. Results Early-stage breast cancer patients demonstrated lower MVC than controls preexercise (− 15%, P = 0.022), and this reduction persisted throughout the 60-MVC exercise (− 21%, P = 0.002). The absolute critical force was lower in patients than in controls (144 ± 29N vs. 201 ± 47N, respectively, P < 0.001), while W’ was similar (P = 0.546), resulting in lower total work done (− 23%, P = 0.001). This was associated with lower muscle activation in the vastus lateralis (P < 0.001), vastus medialis (P = 0.003) and rectus femoris (P = 0.003) in patients. Immediately following exercise, ΔVA showed a greater reduction in patients compared to controls (− 21.6 ± 13.3% vs. − 12.6 ± 7.7%, P = 0.040), while ΔQTw was similar (− 60.2 ± 13.2% vs. − 52.8 ± 19.4%, P = 0.196). Conclusion These findings support central fatigue as a primary cause of the reduction in exercise capacity characterizing early-stage breast cancer patients treated with chemotherapy. Clinical trials registration No. NCT04639609—November 20, 2020.
