Elastic tubing has been proven as effective as free weights again; this time, in teenagers. Several studies have shown that Thera-Band® elastic resistance has similar effects on muscle activation and strength as isotonic resistance (Andersen et al. 2010; Colado & Triplett 2008). Current physical activity guidelines recommend resistance training to improve muscular fitness in youths. A randomized, controlled study in Preventive Medicine by Australian researchers was performed to compare the effects of a resistance exercise program in 15 year old boys and girls using either elastic or isotonic free weight resistance compared to a control group. During the 8-week program, both groups trained twice a week with a PE teacher with a 1:15 instructor-to-participant ratio. They began each session with 5 minutes of aerobic activity and dynamic stretching. Resistance exercises were performed for 2 sets of 8 to 12 reps (Weeks 1-4 = 10-12 reps; Weeks 5-8 = 8-10 reps) with 60 second rests between sets. The 10 strengthening exercises were performed in 40-50 minutes in the same order. Both groups used the Borg scale at 15-18 with an 8-12RM; in other words, participants More >
