Agreement between heart rate deflection point and maximal lactate steady state in young adults with different body masses

Abstract We examined the agreement between heart rate deflection point (HRDP) variables with maximal lactate steady state (MLSS) in a sample of young males categorized to different body mass statuses using index (BMI) cut-off points. One hundred and eighteen (19.9 ± 4.4 years) underwent standard running incremental protocol individualized speed increment 0.3 1.0 km/h for HRDP determination. was determined modified D max method called S.D . MLSS 2-5 series constant-speed treadmill runs. Heart (HR) blood concentration (La) were measured all tests. defined as yielding La increase less than 1 mmol/L during last 20 min. Good observed HR participants (±1.96; 95% CI = −11.5 +9.2 b/min, ICC 0.88; P < 0.001). −0.40 +0.42 km/h, 0.98; The same findings when groups. In conclusion, can be used simple, non-invasive time-efficient objectively determine submaximal aerobic performance nonathletic adult men varying status, according chosen standards
