4.1. Participants
muscle cramps
One participant from the placebo group withdrew from further participation after the baseline measurement due to personal reasons not related to the study protocol. Another participant from the pea supplement group dropped out due to heavy muscle cramps during the walking exercise bout and was therefore unable to complete the minimum walking distance of 20 km. This resulted in 15 participants per subgroup. Participants were predominantly male (80%), aged 70 ± 6 years with a BMI of 24.2 ± 2.8 kg/m
