Response to enquiry “Muscles feel tight in back of leg”.
There are several situations which bring on tight muscles in the back of the lower leg, and there are other situations that bring on tight muscles (hamstrings) in the back of the thighs.
Often, night cramps during sleep tighten the back muscles of the lower legs. Sitting for long periods without exercise will bring on delayed tightness of the back muscles of the lower legs. For example, after sitting for a long period watching TV, one goes to the supermarket to walk about and suddenly the back muscles of the lower legs will tighten up. Another example is after sitting for a long period watching TV, one drives and after some 15 minutes, suddenly the back muscles of the lower legs will tighten up. In these cases, the overly relaxed muscles of the back of the lower legs from sitting readjust their tension and this readjustment comes on belatedly. I experience both of these very often.
Tight hamstrings are the results of weak lower back muscles, twisted lower back muscles, excessive exercise involving the legs like long distance jogging, and weak knees. Weak knees tighten the hamstrings. Although tightness of the back muscles of the thighs occur in both men and women, those who have bigger beer bellies and women who have protruding bellies tend to have tight hamstrings more often than those who have less body fat. Athletes and younger women who jog and exercise a lot also tend to have tight hamstrings as a result of excessive exercise.
