Farinatti, PTV, Simão, R, Monteiro, WD, and Fleck, SJ. Influence of exercise order on oxygen uptake during strength training in young women. J Strength Cond Res 23(3): 1037-1044, 2009-This study investigated the effect of resistance exercise order on the oxygen uptake (...) and energy expenditure (EE). Ten trained women (age, 22 ± 2 years; body mass index, 21 ± 2 kg*m^sup -2^; peak ..., 42.2 ± 2.9 ml*kg^sup -1^*min^sup -1^) volunteered for the study. Data were collected in 5 nonconsecutive days: (day 1) assessment of the peak ... in a maximum effort ramp treadmill protocol; (days 2 and 3) determination of 10 repetition maximum (10RM) for the bench press (BP), machine shoulder press (SP), and pulley triceps extension (TE); and (days 4 and 5) performing 3 sets of each exercise with 3-minute rest intervals between sets and exercises until fatigue using 10RM in 2 sequences of opposite order (sequence A [SEQA]: BP, SP, TE; sequence B [SEQB]: TE, SP, and BP). Total ... was assessed during all exercises, recovery intervals, and for 20 minutes after the end of the sequences. Energy expenditure was estimated from net ... by subtracting rest values from total .... No difference was found between the sequences for the total ... (p = 0.68) and net energy cost (p = 0.29) (SEQA: 25.41 ± 6.51 I and 60.01 ± 29.26 kcal; SEQB: 24.81 ± 4.08 I and 57.02 ± 15.25 kcal; mean ± SD). Conversely, the ... in the rest intervals between sets was higher for BP when it was placed at the end of SEQ B, and the same occurred with TE in SEQ A. In conclusion, the ... was lower for a given exercise when it was performed first as compared with last in a training session for the upper limbs. However, these differences did not affect the overall ... or EE during sequences performed in the opposite exercise order.

INTRODUCTION
Agencies like the American College of Sports Medicine (2) or the American Heart Association (10) have established the importance of strength training to improve health. The benefits of resistance training include not only improved strength, but also favorable modifications on body composition (2). Given the increase...
