Notes
- Abstract:
- The purpose of the present study was to determine intermittent graded exercise results in a higher stage intensity and higher maximal heart rate, minute ventilation, respiratory exchange ratio, and oxygen uptake compared to continuous graded exercise. The participants (11= 11) were collegiate soccer players from the local university. They completed two separate protocols on different days separated by at least 48 hours. The continuous protocol was a graded treadmill test (GXT) consisting of running while grade increased 2.5% every 2 minutes. The intermittent protocol followed the same intensity progression, but with a 1-min active recovery between each stage. During both protocols there was a breath-by-breath analysis of oxygen uptake, minute ventilation, respiratory exchange ratio, and heart rate. V02max during the intermittent protocol was higher (p < 0.05) compared to the continuous protocol (57.7 ± 5.8 ml-kg'1-min 1 vs. 55.7 ± 5.7 ml-kg ’min'1). There was also a significant increase (p < 0.05) in the maximum heart rate achieve during the intermittent protocol compared to the continuous protocol (190 ± 6 bpm vs. 186 ± 6 bpm). Minute ventilation and respiratory exchange ratio did not differ between the intermittent and continuous protocols. All 11 participants satisfied the plateau criteria (increase < 2.1 ml kg '-min'1 with stage increase, Taylor et al., 1955). We concluded that the classic continuous graded exercise test does not effectively measure true maximum oxygen uptake in collegiate soccer players. The intermittent nature of soccer player's training produces adaptations such as increased sodium-potassium pump subunits, increased efficiency of lactate clearance, and re-synthesis of PCr and other energy substrates that contribute to increased performance during the intermittent protocol, which allows for the achievement of the player's maximum oxygen uptake.
