Refuting the myth of non‐response to exercise training: ‘non‐responders’ do respond to higher dose of training

Key points The prevalence of cardiorespiratory fitness (CRF) non‐response gradually declines in healthy individuals exercising 60, 120, 180, 240 or 300 min per week for 6 weeks. Following a successive identical 6‐week training period but comprising 120 min of additional exercise per week, CRF non‐response is universally abolished. The magnitude of CRF improvement is primarily attributed to changes in haemoglobin mass. The potential for CRF...
