Registration Number
NCT05778136
Lead Sponsor
Rigshospitalet, Denmark
Brief Summary

This study evaluates the effectiveness of a supervised one-leg resistance training program in patients with inoperable lung cancer with the primary outcome being rate of force development.

Study design: Single center, two-armed, parallel-group, randomized controlled trial. The primary outcome being rate of force development after 12 weeks of progressive resistance training.

Detailed Description

Muscular dysfunction and sarcopenia are known phenomena in cancer patients, and patients experience reduced muscle function and muscle loss regardless of cancer type or stage. Studies indicate that there are a number of cancer-specific and non-cancer-specific factors that influence muscle dysfunction, such as age, poor nutrition, physical inactivity, cancer pathology and treatment preparations. The decreased muscle function can ultimately lead to cachexia, typically seen in stage III - IV lung cancer patients.

Previous studies have focused on 1-RM tests, muscle mass and functionality as outcomes. However, a central aspect of functionality in lung cancer patients may be the muscle's ability to develop force in a short time. The present study therefore has rate of force development as a primary outcome with muscle mass and functionality as supporting outcomes. In addition, the patients in this study will perform one-leg resistance exercise with the other leg as the control leg. This will eliminate the interpersonal bias normally seen in randomized controlled trials.

Primary Outcome Measures
NameTimeMethod
Muscle strength/function: Rate of Force Development (RFD)Baseline, 6 weeks, 12 weeks

The between group change in Rate of Force Development (Nm/s) of the knee extensors. Assessed in the CON-TREX MJ dynamometer.

Secondary Outcome Measures
NameTimeMethod
Functionality: Postural balanceBaseline, 6 weeks, 12 weeks

Postural one-leg balance on a 5-cm high, 3-cm wide, and 50-cm long plastic bar. Between group change in number of times the participants steps off the bar or needs support to prevent falling in a period of 1 min.

Muscle strength/function: 1 RMBaseline, 6 weeks, 12 weeks

The between group change in 1 repetition maximum in knee-extension and leg-press

Functionality: 6 minutes walk test (6-MWT)Baseline, 6 weeks, 12 weeks

Change in walking distance

Functionality: Sit-to-stand (5reps STS)Baseline, 6 weeks, 12 weeks

Change in time for 5 STS repetitions

Functionality: Sit-to-stand (30s STS)Baseline, 6 weeks, 12 weeks

Change in sit-to-stand in 30 seconds

Muscle strength/function: Isokinetic strengthBaseline, 6 weeks, 12 weeks

The between group change in maximum isokinetic knee extension power (Nm) (60 degrees/s). Assessed in the CON-TREX MJ dynamometer.

Lean leg massBaseline, 6 weeks, 12 weeks

The between group change in lean leg mass (kg) assessed by whole-body dual-energy x-ray absorptiometry (DXA) scan

Muscle strength/function: PowerBaseline, 6 weeks, 12 weeks

The between group change in maximum isometric knee extension power (Nm). Assessed in the CON-TREX MJ dynamometer.
