Periodized Rehabilitation and Beta-alanine Supplementation in Multiple Sclerosis

Moderate intensity endurance training will be performed following a sequence of 5 training sessions every 2 weeks throughout the 12-week intervention. Sessions will include 60min of cycling on a stationary bicycle. Exercise intensity will match 60-80% of the maximal heart rate (HRmax)

Throughout the 12-week periodized intervention, subjects will perform four recurrent 3-week cycles of moderate endurance training (week 1,three sessions, 60min/session, 60-80% HRmax), high intensity interval training (week 2, three sessions, 10min/session, 3x20sec supramaximal sprint interspersed with recovery intervals of 2min), and recovery weeks (week 3, one high intense interval session as described above)

Some subjects will receive the ergogenic supplement beta-alanine.
