The Effects of 8-Week Variable Pace Interval Training on Maximal Oxygen Uptake and Lactate Threshold in Male Four-Year College Basketball Players

Key Points

• The research aims to analyze the effects of 8-week variable pace interval training on maximal oxygen uptake and lactate threshold in male college basketball players.
• Participants: 12 male college basketball players assigned to control (6) and training (6) groups.
• Control group had regular training; training group added 3 weekly sessions of 40-min variable pace interval training for 8 weeks.
• Maximal oxygen uptake measured via the 20m shuttle run test; lactate threshold assessed using a blood lactate analyzer.
• Data analyzed using paired t-tests and independent sample t-tests with effect size calculations.
• Training group showed significant increase in maximal oxygen uptake from 50.3 to 55.0 mL/kg/min (p<0.001, g=1.54).
• Lactate threshold in the training group increased significantly from 3.53 to 4.17 mmol/L (p<0.001, g=1.94).
• Control group showed no significant changes in oxygen uptake (p=0.21).
• Changes in both maximal oxygen uptake and lactate threshold were significantly greater in the training group (p<0.001).
