(v.) To "samba" : To lose muscle control in extremities after apnea. Usually occurring in spearfishers who hyperventilate (purge too much CO2) before a breath hold - this is extremely dangerous and why you never dive alone!
Always dive with a buddy and never practice "
static breath hold" techniques while near water. CO2 regulates the body's exchange of gasses so if you purge too much you
will use more oxygen while diving. Take a freediving course to learn a proper "freediving breathe-up"
