Many of us want to have a ample amount of muscle but as we age we also do not want to stress out our aging joints. I have recognized as I started getting up their in age my goals in the gym have changed from being big and strong to just looking like I am big and strong. However, we all recognize that if we want to be a mass monster; we need to lift that heavy weight, right? But can we maintain a significant amount of muscle mass as we age by lifting lighter reps for higher repetitions and taking it easy on our old joints?.
Time under tension
The term, "time under tension" or TUT for short, refers to the amount of time your muscles are under a load during resistance training. Ideally them more time under tension the better for hypertrophy. So how do we perform the lift? Tempo of training should be a controlled, about1.5 second eccentric movements and explosive concentric movements. A total of maybe 1.5 seconds per repetition. Let's say, you have a max bench press of 315 lbs. As you see below, the time the muscle is under tension pressing 315lbs 1 time for 5 reps compared to pressing 50%1RM for 15 reps is much greater. Not only is there a big difference in the TUT as well as the total volume lifted. Remember, since the weight loads are light rest periods can be cut to about 1 minute further increasing metabolites.
What does science have to say
There is a compelling body of research that indicates that within wide limits, you build as much muscle from training with relatively light weights as you do from heavier loads. In fact, superior gains have been shown when lifting weights >65% 1RM. How does this happen? Researchers have discovered that fast-twitch fibers *Type II) are progressively activated as a light-load set nears muscle failure, thus indicating that tension is specific to the level of exerted effort. So, if you do a set of 15 reps the 1st few will be easy but as we reach the last few repetitions, the muscle fibers exhaust. Also, while the load is much higher, science has found that metabolites are produced during high rep training that may contribute to hypertrophic gains.

315 x 5 sets of 1 rep – 1575lbs total.. Total time- about 7.5 seconds.
150lbs (50%1RM) x 5 sets of 15 reps – 11250lbs total. Total time about 112.5 seconds
